What to verify on a video marketing agencies selection checklist before signing

What to take away

A video marketing agencies selection checklist is a set of pass or fail tests you run before signing, covering compliance, creative standards and commercial terms.

Treat it as a gate, not a scorecard. If a supplier fails a mandatory line, stop.
Check cookie and tracking behaviour early, because it affects every video embed you publish.
Ask for named references and verify two of them yourself.
Agree exit terms, asset ownership and notice periods in writing before the first invoice.

Start with the compliance gate

Compliance lines come first because they are hard to fix later. Ask how the agency handles consent for embedded players and remarketing pixels.

The ICO's guidance on the use of storage and access technologies sets out when consent is needed for cookies and similar tools. It applies to video embeds as much as to any other script. If the agency cannot explain its approach in plain words, that is a fail.

Add a line on advertising claims. The ASA's AdviceOnline library is where you check the specific rules that apply to your sector before creative goes live. Ask who signs off claims, and record that name in the contract.

Check creative and distribution standards

Agencies that distribute content natively should show they follow published creative principles. The IAB UK native distribution principles cover labelling, disclosure and how paid content sits alongside editorial.

Creative and distribution checks

Follow IAB UK native distribution principles
Two recent examples of good disclosure
One example where disclosure went wrong
Request paid social account structure
Confirm who holds admin access

Ask for two recent examples where disclosure was handled well. Then ask for one where it went wrong and what changed.

For paid social and search, request the account structure, not just the results. You want to see who holds admin access.

Verify the evidence pack

This is the part buyers skip. Set a rule: no reference, no shortlist.

Two named client contacts, with permission to call them.
Three case examples with a stated objective and a stated result.
A clear statement of what the agency did versus what the client did.
Named freelancers or subcontractors who will touch your account.
Current professional indemnity and public liability cover.

If the agency cannot name the people doing the work, assume the pitch team will not deliver.

Compare commercial terms properly

Rates matter, but structure matters more. For example, a team paying £400 a month for editing retainers may still face separate charges for strategy, talent and media.

Ask for a full cost model across twelve months, including ad spend handling fees. Then compare it against the reviews and comparison methods used across this section, which explain how to score suppliers on evidence rather than presentation.

Watch for evergreen usage rights, exclusivity clauses and automatic renewal. Each one can lock you in long after the campaign ends.

Test the working relationship

Run one small paid task before you commit to a retainer. A single edit, a script or a media plan will show you response times, revision behaviour and how the agency handles feedback.

Set a response time expectation in writing. Ask what happens if the named lead leaves. Ask how often you will speak to a person rather than read a dashboard.

If the agency only wants to talk about reach, that is a warning. You need a view on how the work supports a commercial outcome.

Run the final due diligence pass

Before signature, confirm the entity you are paying. Check it on Companies House, and match the name to the contract and the invoice.

Then work through the remaining lines.

Data processing agreement signed and dated.
Asset ownership and source files confirmed.
Notice period and exit assistance stated.
Named account lead and escalation contact.
First ninety day plan with review points.

A written checklist turns a persuasive pitch into verifiable facts. For a worked example of how that looks, the England agency reviews show how evidence is presented and challenged.

Common questions

How long should a selection checklist take to complete?

Allow two to three weeks for a shortlist of three. Most of that time goes on reference calls and the small paid task, not on reading proposals.

Should the checklist differ for a production company and a marketing agency?

Yes. A production company needs more checks on crew, insurance and usage rights. A marketing agency needs more on media buying, tracking and reporting.

What is the single most useful question to ask?

Ask which named person will run the account day to day, then speak to that person before you sign. If the answer changes, treat it as a fail.

Do we need legal review before signing?

For any contract above a modest annual value, yes. Ask a solicitor to check ownership, liability caps and termination. It is cheaper than a disputed exit.
