There is an awkward problem at the beginning of a career in digital advertising.
Employers want candidates who understand campaigns.
Real campaigns involve spending money.
Nobody particularly wants to give an inexperienced applicant control of thousands of pounds of advertising spend so that they can acquire the experience required to get their first job.
It sounds like a closed circle.
It isn’t.
Paid media is actually one of the easier professions in which to demonstrate how you think before anybody lets you near a live client account. You can learn the platforms, analyse existing advertising, build campaign plans, work with sample data, create ads, study landing pages and show how you would measure performance without pretending you have achieved results you have not.
That distinction matters.
A good junior paid-media candidate does not need to arrive having managed a £500,000 account.
They need to demonstrate that they understand what advertisers are trying to achieve, how online advertising systems help them achieve it and how they would decide whether a campaign was working.
First, understand what a web advertising job actually is
“Digital marketing” covers an enormous range of work.
Prospects currently identifies entry-level roles including digital marketing executive, paid media assistant, PPC specialist, SEO executive, social media executive, CRM assistant and content marketer. Skills England’s digital marketer occupational standard includes roles such as PPC analyst, display advertising executive, programmatic executive, social media specialist and digital marketing campaign manager.
Those jobs overlap, but they are not identical.
A paid search specialist might spend much of the day working with search queries, keywords, bids, conversion data, advertising copy and landing pages.
A paid-social executive may work more heavily with audiences, creative testing, video, images and campaign objectives.
A programmatic role can involve display inventory, audiences, bidding technology and ad platforms.
A performance marketer may work across several paid channels and be judged primarily on commercial results.
An advertising agency account executive may spend more time translating a client’s commercial objectives into briefs, coordinating specialists and explaining results.
Before applying for everything containing the word “digital”, work out which parts actually interest you.
Learn the commercial logic before obsessing over the platform
Beginners sometimes approach paid advertising backwards.
They learn where buttons are in Google Ads and conclude that they have learned PPC.
Platforms change.
Interfaces change.
Automation changes.
The commercial questions underneath them change much more slowly.
Suppose a retailer sells a product for £100.
How much can it afford to spend acquiring a customer?
To answer that, you need considerably more information.
What is the gross margin?
How many customers return?
How often?
Are customers buying one product or several?
How many people who click an advert eventually buy?
Do customers usually convert immediately or several weeks later?
What proportion of apparent conversions would have occurred anyway?
A person who knows every menu inside an advertising platform but never asks those questions may be less useful than a beginner who understands why they matter.
Paid advertising is not fundamentally about buying clicks.
It is about buying attention with the expectation that enough of that attention will create sufficient value to justify its cost.
Everything else follows from that.
Learn the basic advertising maths
You do not need advanced mathematics to enter paid media.
You do need to be comfortable with numbers.
Imagine a campaign spends £1,000 and receives 2,500 clicks.
Its average cost per click is £0.40.
If 100 of those visitors buy, the conversion rate is 4%.
The advertising cost per acquisition is £10.
If those customers collectively generate £4,000 in measured revenue, the campaign has generated £4 in revenue for every £1 of advertising spend.
But even then you cannot simply declare the campaign profitable.
Revenue is not profit.
There may be product costs, fulfilment costs, discounts, returns, agency fees and other marketing costs.
That habit — asking what the number actually means — is enormously useful in performance marketing.
You should understand common concepts such as impressions, reach, clicks, click-through rate, cost per click, conversions, conversion rate, cost per acquisition, revenue and return on advertising spend.
Do not merely memorise the formulas.
Learn what could cause each number to change.
Get comfortable with Google Ads without pretending certification equals experience
Google itself offers free Google Ads training through Skillshop, covering areas including Search, Display, Measurement, Video and Shopping. Google also offers certification assessments in its advertising products. Google Ads training on Skillshop
That makes Skillshop a sensible resource for somebody trying to enter paid search.
But there is an important caveat.
Passing an assessment does not magically turn somebody into an experienced PPC practitioner.
Google itself recommends that candidates have on-the-job experience using Google Ads and understand advertising concepts and best practices before taking its certification assessments. Google Ads certifications currently last one year before renewal is required.
So put a certification in the correct place.
It can prove that you have deliberately studied the platform and achieved a recognised standard in an assessment.
It cannot prove that you have successfully managed a client’s advertising budget for a year.
Employers know the difference.
You should too.
Build a portfolio before somebody gives you a campaign
If you were applying for a design job, nobody would find it strange for you to show a portfolio.
Aspiring paid-media professionals should think similarly.
Your portfolio does not need to claim real campaign results.
It should demonstrate how you approach an advertising problem.
Imagine a fictional independent furniture company wants to sell more desks online.
You could create a short campaign case study explaining the business objective, proposed audiences, campaign structure, keyword themes, sample advertisements, landing-page recommendations, measurement plan and what you would test first.
The exercise becomes particularly valuable when you explain why.
Why separate branded and non-branded search?
Why prioritise one group of products?
Why exclude another?
Why send traffic to a category page rather than the homepage?
What would count as a conversion?
How would you decide whether an expensive keyword was worth retaining?
What information would you want from the business before deciding how much to spend?
Those questions reveal far more than a decorative screenshot of an advertising dashboard.
Prospects’ current guidance for people trying to enter digital marketing specifically recommends building practical evidence and suggests exercises including mock Google or TikTok campaigns, digital-strategy analysis, email sequences, social-media strategies and SEO audits. It advises presenting the objective, strategy, tools and results clearly.
For a simulated exercise, of course, there are no genuine results.
Say so.
Never invent campaign performance
This deserves its own section because digital-marketing CVs have a temptation that many other CVs do not.
Numbers look impressive.
Increased ROAS by 275%.
Reduced CPA by 43%.
Generated £80,000 in revenue.
Those claims can transform a CV if they are true.
They can also destroy your credibility if they are fiction.
If you have constructed a portfolio campaign rather than run it, label it clearly as a speculative, simulated or portfolio exercise.
You can still demonstrate useful analysis.
For example:
Developed a portfolio paid-search strategy for a fictional online furniture retailer, including campaign structure, keyword themes, negative-keyword logic, sample copy, conversion definitions and a proposed testing framework.
That is completely respectable for an applicant seeking their first role.
Pretending the imaginary retailer generated £200,000 is not.
Create one excellent campaign case study rather than ten shallow ones
Your first portfolio does not need to resemble an agency’s entire client list.
A single detailed case study can demonstrate an extraordinary amount.
Start with the business rather than the ads.
Suppose your hypothetical company sells premium dog food online.
Who buys it?
What problem does the product solve?
What makes it different?
How expensive is it?
Is repeat purchasing important?
Are shoppers likely to know the brand already?
What might they search for?
What would make them hesitate?
What action should the advertising produce?
From that foundation, build the advertising strategy.
You might identify several categories of search intent. Somebody searching for the brand name is in a different position from someone searching “best food for senior dogs”. Someone searching “dog food” is broader still.
Think about what message fits each stage.
Then think about the landing page.
An advert can do its job perfectly and still produce poor commercial results if it sends somebody to a confusing page with weak information, slow loading or an unclear route to purchase.
That is why good paid-media people develop interests beyond the advertising interface.
Learn to critique landing pages
A paid-advertising job frequently sits at the intersection of several disciplines.
You may not design the website.
You may not write all the copy.
You may not control prices or stock.
But those things can determine whether your advertising works.
Take a real website and imagine you are sending paid traffic to one of its pages.
Ask:
Does the page fulfil the promise made in the advert?
Can the visitor immediately understand what is being offered?
Is the intended action obvious?
Does important information appear early enough?
Are there unnecessary distractions?
Would someone arriving on a mobile phone have a good experience?
What objections might prevent a purchase or enquiry?
Do not redesign the entire internet.
The value of the exercise is demonstrating that you understand advertising performance is not created by the ad platform alone.
Learn measurement early
One of the quickest ways to distinguish a thoughtful beginner from someone who has merely watched a few advertising videos is to ask:
“What should we measure?”
“Clicks” is rarely enough.
Suppose you are advertising a solicitor.
A visitor clicking an advert does not necessarily create any business value.
A completed enquiry might.
But even enquiries vary in quality.
A personal-injury enquiry for a firm that only handles commercial property may be worthless.
An enquiry from a business seeking a £20,000 piece of legal work is very different.
Now imagine an ecommerce business.
The conversion might be a sale, but even there you could care about order value, margin, new versus returning customers and repeat purchasing.
Your portfolio exercises should therefore include a measurement section.
Explain what the primary commercial outcome is, which secondary actions may be worth observing and how you would distinguish useful conversions from vanity metrics.
Understand attribution without pretending it is perfect
Advertising platforms are very good at producing numbers.
Numbers can create an illusion of certainty.
Imagine someone sees a paid-social advert on Monday, searches for the company on Wednesday, reads two reviews on Thursday and finally purchases through a Google search advert on Friday.
Which channel caused the sale?
There is no single universally correct answer.
The platforms may each view the journey differently.
Privacy controls, consent, multiple devices and offline interactions complicate matters further.
As a junior applicant, nobody expects you to solve the entire problem of marketing attribution.
They will, however, notice if you understand that a reported conversion is not necessarily the same thing as proving an advert single-handedly caused the purchase.
A little healthy scepticism around marketing data is a valuable professional skill.
Learn enough about creative to talk to creative people
Performance marketing is increasingly difficult to separate neatly into “creative people over there” and “numbers people over here”.
Paid-social campaigns in particular depend heavily on the creative.
A marketer therefore needs to think about the opening seconds of a video, the image, headline, offer, call to action, audience and landing page as parts of one system.
You do not necessarily need to be a graphic designer or video editor.
But you should be able to look at an advertisement and ask sensible questions.
Who is this for?
What gets their attention?
What problem is being presented?
What is the promise?
What evidence supports it?
What happens next?
What could we change in the next version to learn something?
“Make another ad” is not much of a testing strategy.
Build a testing hypothesis
One of the best phrases to understand early in digital advertising is:
If we change X, we expect Y because Z.
For example:
If we emphasise free delivery in the headline, we expect more product-page visitors to click because delivery cost appears to be a recurring objection in customer reviews.
Now you have a reason for the test.
That is considerably stronger than changing the headline, image, button, audience and landing page simultaneously and then declaring victory when performance moves.
Your portfolio can include several proposed tests.
The important thing is demonstrating disciplined thinking rather than predicting that every test will succeed.
Real advertising contains failed tests.
That is why they are tests.
Get some real experience without waiting for a graduate scheme
Eventually, simulated campaigns should give way to genuine experience.
That does not mean persuading somebody to hand you £10,000.
A local charity might need help understanding its digital presence.
A student society may need to promote an event.
A small business may let you analyse its marketing even if you do not control its ad account.
You might run your own small website, newsletter or ecommerce experiment.
The National Careers Service specifically suggests that aspiring marketing professionals can develop experience through volunteering, including helping charities with social media and communications. It also recognises university, college, apprenticeships, progression from junior roles and direct application as routes into marketing.
The DMA similarly notes that a degree is not the only route into marketing and identifies work experience, online courses and apprenticeships as alternatives.
Real experience matters because genuine audiences rarely behave as neatly as case studies.
Do you actually need a degree for digital advertising?
No single degree is mandatory for most digital-advertising careers.
The National Careers Service says employers recruit marketing graduates from several relevant subjects but also describes non-degree routes. Prospects similarly states that digital marketing is open to graduates of all disciplines, although advertising, communications, business, creative design, journalism and marketing can be particularly useful.
That makes sense.
Digital advertising combines skills from several worlds.
Marketing teaches you about markets, customers, positioning and promotion.
Psychology can help you understand behaviour and decision-making.
Statistics and economics can develop quantitative reasoning.
English, journalism and communications can strengthen messaging.
Computer science and data subjects can be useful in increasingly technical marketing environments.
Design can be valuable in creative advertising.
Business subjects help put campaigns into their commercial context.
The important question is not whether your degree title says “digital marketing”.
It is whether you can turn what you have learned into evidence relevant to the work.
If you are choosing a university course specifically for marketing
If you already know that advertising or digital marketing interests you, look beyond the degree title.
Prospects notes that current marketing programmes can differ substantially in emphasis. Some courses lean towards creative and strategic areas such as communications, branding and campaign development, while others place greater weight on data, PPC, SEO, analytics and measurement.
Look at the actual modules.
Also look for opportunities to work on live briefs, placements, industry projects and analytics.
A course that allows you to graduate with several pieces of demonstrable work may be more useful for your first job search than one in which every assessment disappears into an academic filing system after marking.
If you are currently preparing a university application, browsing business and management personal statement examples by subject can help you see how other applicants connect academic interests, projects and professional ambitions. Personal Statement Examples also has a leadership and marketing personal statement example that discusses online marketing, research, metrics and the relationship between marketing activity and wider business strategy.
Use examples to understand how applicants develop their reasoning, rather than borrowing their wording.
A strong application should explain what made you interested in marketing and what you have done with that interest.
A better personal statement starts with something you actually investigated
“I have always been passionate about marketing” is not especially informative.
You could make the subject much more convincing by discussing something you have actually noticed.
Perhaps you became curious about why two companies selling almost identical products advertise themselves completely differently.
Perhaps you ran social media for a club and discovered that posts generating the most likes did not necessarily produce event bookings.
Perhaps a business project made you interested in customer-acquisition costs.
Perhaps you built a small website and discovered that attracting visitors was harder than creating it.
Perhaps you became interested in the privacy and ethical questions surrounding targeted advertising.
These are useful beginnings because they generate questions.
Why did one message outperform another?
Why do consumers respond to one offer but ignore another?
How should an advertiser decide how much a customer is worth?
How do you measure something that happens across several channels?
How far should personalisation go?
That is much more interesting than announcing that you are “creative, hardworking and passionate about brands”.
What if you already have a degree?
Do not automatically assume you need another one.
Prospects says postgraduate qualifications in digital marketing are increasingly available and may be particularly useful for somebody whose first degree is unrelated, but it does not describe a master’s as essential for entry.
There are several possible routes.
You could pursue postgraduate study.
You could take a professional qualification.
You could complete platform training.
You could build a portfolio.
You could enter marketing through a junior role.
You could move sideways from sales, ecommerce, content, customer service or another commercial function.
If you are considering postgraduate marketing study because you want to combine stronger commercial knowledge with analytics, the Business Analytics master’s personal statement example on Personal Statement Examples is also an interesting comparison because it connects technical analysis with marketing and business decision-making.
The important question is what gap the qualification solves.
Learn spreadsheets properly
There are glamorous bits of advertising.
Spreadsheet work rarely appears in recruitment videos.
It matters anyway.
Get comfortable with sorting, filtering, basic formulas, percentages, conditional logic, lookups and pivot tables.
If somebody gives you thousands of rows containing campaign, spend, clicks, conversions and revenue, you should gradually become capable of turning that information into something useful.
Which campaign spends the most?
Which produces the cheapest customers?
Which has deteriorated?
Which appears strong on revenue but weak after considering cost?
Where did the change begin?
Can you present the answer clearly?
An entry-level marketer who can interrogate data and explain what they found has an extremely useful foundation.
Do not overlook writing
Paid advertising contains far more writing than people expect.
There are headlines.
Descriptions.
Calls to action.
Creative briefs.
Client emails.
Reports.
Presentations.
Explanations of why performance changed.
Recommendations about what should happen next.
Bad writing creates bad communication even when the analysis behind it is excellent.
Practise explaining a campaign in plain English.
Do not write:
The campaign experienced a 17% WoW diminution in CVR concomitant with a 23% increase in CPC, resulting in consequential CPA inflation.
Write:
Cost per acquisition increased because clicks became more expensive while a smaller proportion of visitors converted. I would first investigate whether this was caused by a change in traffic quality, the landing page or both.
The person reading your report may not spend all day inside an advertising platform.
Good marketers translate.
Understand that AI changes the work without removing the need to understand it
Modern advertising platforms contain increasing amounts of automation.
AI can assist with creative production, analysis, audience modelling, bidding and campaign management. Prospects now specifically highlights AI, data ethics and privacy as areas digital marketers should understand as the profession changes.
This makes fundamentals more important, not less.
If a system recommends something, somebody still has to decide whether that recommendation makes commercial sense.
If AI produces twenty headlines, somebody still needs to judge whether they are accurate, distinctive and appropriate.
If automated bidding spends more aggressively, somebody needs to understand the business objective against which it should be judged.
Knowing how to press fewer buttons does not make marketing judgement obsolete.
Agency or in-house?
Your first paid-media role may be at an agency or inside one organisation.
Both can be excellent training environments.
Agency work may expose you to several industries, business models and campaign types quickly. You also learn the discipline of explaining performance to clients.
An in-house role can give you deeper knowledge of one organisation, its customers, commercial economics and wider marketing activity.
Neither environment is automatically better.
When interviewing, ask what you will actually do.
Will you work in the platforms?
Who will train you?
What accounts would you support?
Will you see commercial data beyond advertising metrics?
How is performance reviewed?
A glamorous agency name matters rather less if your entire first year consists of copying figures between spreadsheets without anybody explaining what they mean.
How to write your first paid-media CV
Your CV should make practical evidence difficult to miss.
If you have not yet held a marketing job, do not hide your best work at the bottom under “interests”.
A portfolio project can sit beneath a heading such as Digital advertising projects.
For example:
Paid search portfolio project – ecommerce
Developed a Google Search campaign strategy for a fictional specialist retailer. Researched search intent, created keyword themes and negative-keyword rules, wrote sample advertisements, mapped landing pages and defined a measurement and testing plan. Presented recommendations in a ten-slide campaign proposal.
That is more useful than:
Interested in PPC and social media.
Certification can then support the project rather than replace it.
If you have Google Ads certification, say which certification and when you obtained it.
If you know Excel, explain what you can actually do with it.
If you have run advertising, use genuine numbers where confidentiality permits.
Evidence beats adjectives.
Prepare for the interview by expecting campaign questions
A junior interview is unlikely to consist entirely of technical platform trivia.
You may be shown a campaign and asked what you notice.
You may be asked what you would do if conversion rate suddenly fell.
You may be asked how you would launch a new product with a limited budget.
You may be shown an advert and asked how you would improve it.
You may be asked why one keyword is more valuable than another.
There may not be one perfect answer.
Interviewers are often interested in how you reason.
A useful structure is:
What do I know?
What do I not know?
What would I investigate?
What decision might follow?
Suppose conversion rate falls by 30%.
Do not immediately announce that the adverts need rewriting.
Perhaps the website broke.
Perhaps mobile checkout stopped working.
Perhaps tracking changed.
Perhaps the campaign began attracting different searches.
Perhaps a promotion ended.
Perhaps the figure is based on a tiny sample.
Strong analysts diagnose before prescribing.
A portfolio project you could build this weekend
Choose a real business whose website and public advertising you can observe, but do not claim to represent it.
Write a short fictional brief.
For example:
A specialist UK running-shoe retailer wants to increase first-time customer sales without allowing customer-acquisition costs to exceed an agreed level.
Research the market.
Choose one advertising channel.
Define the target audience and objective.
Develop campaign structure.
Create sample advertisements.
Choose the landing pages you would use.
Explain the conversions you would measure.
Propose three tests.
Identify the information you would need from the business before launch.
Finally, add a page called What I cannot know from the outside.
That last page may be one of the strongest parts.
Perhaps you need product margins.
Customer lifetime value.
Existing conversion rates.
Historical advertising performance.
Stock levels.
Seasonality.
Average order value.
That demonstrates commercial maturity.
Marketing is not about confidently inventing missing information.
It is about knowing when missing information matters.
What employers should see when they look at you
For an entry-level web-advertising role, nobody sensible should expect you to arrive as a fully formed performance-marketing director.
They should be able to see the beginnings of the right habits.
You understand that advertising exists to achieve business objectives.
You are comfortable with numbers.
You can write.
You can learn platforms.
You ask questions about measurement.
You recognise the importance of the landing page and customer journey.
You can explain why you made a decision.
You know the difference between genuine evidence and an impressive-looking claim.
And, perhaps most importantly, you are interested enough in the work to have started practising before somebody pays you to do it.
Your first paid-media job checklist
Before applying, aim to have:
- a basic understanding of paid search, paid social and how they differ;
- confidence with the main advertising metrics and the commercial meaning behind them;
- at least one detailed campaign portfolio project;
- examples of advertisements or creative briefs you have produced;
- a basic measurement plan;
- enough spreadsheet ability to analyse campaign data;
- familiarity with landing-page and conversion principles;
- relevant platform training or certification where useful;
- a CV that shows projects and evidence rather than merely claiming an interest in marketing; and
- a clear explanation of why this part of digital marketing interests you.
You do not need to wait until somebody gives you access to a major advertising account before you begin learning how advertisers think.
Start with a business problem.
Work out who the customer is.
Decide what action you want them to take.
Construct the advertising logic.
Decide how you would measure success.
Then question your own assumptions.
That is already much closer to doing the job than simply saying you want a career in digital marketing.
