Overview

Digital marketing assessments are practical and data-heavy. You are typically given a set of channel results, a landing page or an ad account summary and asked what you would change, in what order and why. The tasks are close to the daily work of the job, which is why they separate people who have run campaigns from people who have watched them run. This page covers the formats and how they are marked.

Why employers assess this role

Platform names on a CV say very little — anyone can list the major ad platforms, and dashboards make it easy to describe results you did not produce. A practical task shows immediately whether a candidate can find the problem in an account, and whether they change one thing at a time or everything at once.

What you'll be asked to do

Diagnose an underperforming campaign

A campaign missing its target, with enough data to locate the problem if you look in the right order. The sequence you check things in is marked as much as the conclusion.

•Impressions are steady, clicks are steady, conversions have halved — work out where to look first
•Cost per acquisition has risen across every campaign in an account; identify the plausible causes
•One ad set consumes most of the budget and delivers the worst results; decide what to do

Critique a landing page or ad

You are shown a page or a set of ads and asked what is losing conversions. Assessors look for specific, prioritised observations rather than a list of everything that could be improved.

•Name the three changes you would make to a landing page and rank them by expected impact
•Explain why an ad with a high click-through rate might be attracting the wrong traffic
•Identify the mismatch between an ad promise and the page it leads to

Design a test

A proposed change and a requirement to say how you would judge it. This is where most candidates lose marks by changing several variables and then being unable to attribute the result.

•Set out a test for a new landing page headline, including what you would measure
•Explain how long you would run a test before acting on it, and why
•Say what result would make you keep the original rather than the variant

Allocate and pace budget

A month of spend across channels, usually with one channel over-pacing. You are scored on whether you protect the outcome or simply flatten the spend.

•Reallocate spend halfway through a month when one channel is running hot
•Decide which channel to pause when the budget is cut without notice
•Justify keeping spend in a channel that looks expensive on last-click reporting

Practise a Digital Marketing Specialist assessment before the real one

Run the same AI job simulations companies use to evaluate applicants. You get a scored report showing where you're strong and where you're not, plus what to work on.

Sample tasks — and what strong looks like

Conversions have dropped sharply while traffic and click-through are unchanged. Set out how you would find the cause.

Mid

What strong looks like: Checks whether the drop is real before explaining it — tracking, a site change, a form failure — then segments by device, source and campaign. Weak answers assume an audience or creative problem and start rewriting ads without confirming that conversions are actually being recorded.

You are given a landing page and asked what is costing conversions. Name and rank your changes.

Entry

What strong looks like: Picks a small number of specific problems tied to what the visitor is trying to do — an unclear offer, a form asking for too much, a message that does not match the ad — and ranks them. Weak critiques list generic best practice such as adding testimonials or shortening copy with no link to this page or this audience.

Two channels report the same conversion, and the totals no longer match the finance figures. Explain how you would handle it.

Senior

What strong looks like: Recognises this as an attribution overlap rather than a data error, states which source is being treated as the reference, and proposes a consistent basis for reporting going forward. Weak answers pick the more flattering number.

Propose a test for a page you believe underperforms, and say what would make you reject the result.

Mid

What strong looks like: Changes one thing, names the metric in advance, states roughly how much data is needed before deciding, and names a guardrail such as lead quality that must not degrade. Weak submissions test a full redesign and cannot say afterwards which change mattered.

How to prepare

#1
Practise reading a performance table and writing down what you would check first, second and third before you write any recommendation.
#2
Rehearse the discipline of confirming a metric is real before explaining it. Tracking breakages account for a large share of the drops these assessments describe.
#3
Work through a few live landing pages and force yourself to name only three prioritised changes, since unranked lists score poorly.
#4
Learn to state a test in one sentence: one variable, one metric, one decision rule.
#5
Practise explaining a channel result to someone with no marketing background, because the written sections are usually pitched at a commercial reader.
#6
Do a timed mock with a full data set rather than isolated questions, as pacing across diagnosis and recommendation is a common failure.

Common mistakes

Explaining a metric change without first checking whether the measurement itself broke.
Recommending a long list of improvements with no order of priority.
Testing several changes at once and then being unable to say which one worked.
Judging channels on click-through rate rather than on what happens after the click.
Quoting platform-reported conversions as fact when they overlap across channels.
Filling the answer with platform terminology instead of stating what would actually change in the account.

How it's scored

Criterion	What strong looks like
Diagnostic order	Eliminates measurement problems first, then segments the data, and only then proposes a cause. The sequence is visible on the page.
Prioritisation	A short ranked set of actions with the expected effect stated, rather than an exhaustive list of possibilities.
Measurement rigour	One variable at a time, a metric named before the test runs, and a stated basis for deciding when to stop.
Commercial awareness	Recommendations are connected to revenue or qualified pipeline rather than to traffic and engagement alone.
Communication	The recommendation is legible to someone outside the channel, with jargon either avoided or explained in passing.

Frequently Asked Questions

Which platforms will I be tested on?

Most assessments are platform-neutral and give you the data rather than access to an account, because the reasoning transfers and the interface does not. Where a specific platform is used it is normally stated in advance.

Do I need to do the arithmetic by hand?

You will usually need basic derived figures such as cost per acquisition or conversion rate. A calculator or spreadsheet is normally allowed, and the marks are for what you conclude from the number, not for computing it quickly.

Is it a problem if I have only worked in one channel?

Not necessarily. The diagnostic habits transfer, and assessors generally weight the reasoning over channel-specific detail. Where a task sits outside your experience, saying what you would check and what you would need to learn scores better than bluffing.

How long should the written recommendation be?

Short. A ranked set of actions with a sentence of reasoning each is enough. Length is not scored and long answers frequently bury the recommendation.

Can I practise a realistic one first?

Yes, and it is worth doing before an employer is watching. Cohesyve gives you three scored assessments at no cost, with a report showing whether you are losing marks on diagnosis, prioritisation or measurement.
