The evidence to demand for marketing work you cannot see, service by service

Most of what a marketing agency does happens inside systems the client never opens, which is why a completed work report is the least useful page in the monthly pack. The fix is not to trust less. It is to ask for the evidence that already exists, because almost every marketing task leaves a record in a place with a timestamp and an author on it. A keyword plan is a document with a version history. A campaign change is a row in the account's own change log. A technical fix is a before and after on a URL anybody can fetch. Once you know which record goes with which service, verification takes minutes a month rather than trust.

This page sorts evidence by how hard it is to fake, then lists what to ask for against each service an Indian agency commonly sells.

The evidence hierarchy, strongest first

The rule that falls out of this table is short. Ask for the top two wherever they exist, accept the third for strategy work, and treat the bottom two as illustration rather than evidence.

What to ask for, service by service

Paid search and paid social management

• The account's own change history, filtered to the month, which you can open yourself if the account is in your name.
• A list of campaigns, ad groups and audiences created or paused, with dates.
• Search term exclusions added, which is the single clearest sign somebody is actually working the account.
• The billing side separately, so the fee and the media spend are two lines rather than one.

Technical site work

• A list of URLs changed and what changed on each. A page either serves the new title or it does not, and you can check it in a browser.
• The coverage and indexing reports from the search console property, which lives in your account.
• Before and after page speed readings on named URLs, taken with a tool you can run yourself.

Content and page production

• Live URLs. A page that was written and not published is work in progress, not a deliverable.
• Word count and publication date per page, which the page itself carries.
• The brief that each page was written against, so you can see what it was meant to achieve.

Social media and creative

• Permalinks to every published post, which is a complete and checkable record.
• The content calendar as a document with version history rather than a monthly image.
• Source files for anything designed, handed over as they are made rather than at the end. Our page on the ten parts of a social media agency brief covers how to write the scope so this is already agreed.

Website and conversion work

• A staging URL during the build and a deployment date for each release.
• Repository access or at minimum a release note per deployment.
• For a conversion test, the variant URLs, the dates it ran and the number of visitors in each arm.

Tracking and analytics configuration

• A written list of every conversion action with what it fires on and which platform it reports to.
• A test enquiry you submit yourself, which should appear in every system within the hour.
• The tag container's own version history, which records every publish with an author.

Strategy, research and planning

• The document, with version history, named contributors and the dates it was worked on.
• The data it was built from, attached rather than described.
• A decision log saying what was considered and rejected, which is the part that shows the thinking.

The one check that replaces most of the others

Hold the accounts. If the ad accounts, the analytics property, the search console property, the tag container, the domain and the business profile are all in your legal entity's name, then four of the seven services above become self verifying, because the system's own log is open to you whenever you want it. If they are in the agency's name, every item on this page depends on them choosing to show you, and the handover at the end of the relationship becomes a negotiation. Settle this in the first week, which is also the right week to settle the rest of the operational list in the marketing onboarding checklist.

How to run this monthly without becoming the quality department

• Pick two services a month and verify those, rotating. Full verification every month turns into a second job for both sides.
• Open one thing yourself rather than asking for it. Two minutes in the change log is worth more than a page of report.
• Verify one claim at random. The point is not suspicion, it is that a relationship where claims are occasionally checked produces more careful claims.
• Write down what you verified and the date. Six months later that record is the honest history of the engagement.

Questions about verifying agency deliverables

Is it insulting to ask an agency for evidence

A good agency expects it and most of them keep this material already, because they need it internally. The ones that find the request difficult usually have a record keeping problem, and that is worth knowing early.

What if the work genuinely leaves no record, like a strategy session

Then the record is the document that came out of it, with its version history, plus a decision log. Thinking is a real deliverable and a dated document is the right evidence for it.

The agency only gives me screenshots. What should I say

Ask for the same thing one level up the table. Instead of a screenshot of the change history, ask to be added to the account so you can open it. The request is specific, it is cheap for them to grant, and granting it ends the conversation permanently.

How much of my own time should this take

About twenty minutes a month after the first time, which is two services verified from records you can open. The first pass takes a couple of hours because you are finding out where everything lives.

Does this apply to a freelancer as well as an agency

It applies more, because a freelancer usually has no account management layer and no handover process. Agree where the work will live before it starts, and the rest follows.

What is the single most revealing thing to ask for

The search term exclusion list on a paid account, or the list of URLs changed on a technical engagement. Both are short, both are specific, and neither can be produced by somebody who did not do the work.

The claim this page cannot verify, and the reading that can

One kind of marketing claim leaves no record anywhere in this list. If an agency tells you it has improved how your business appears when buyers ask an assistant, nothing in an ad account, a search console property or a tag container will show it. The only evidence of that kind is a saved reading, meaning the question asked with no brand name in it, the full answer, the sources it used and the date. When we took 50 such readings on India buying questions on 22 October 2026, across ChatGPT and Gemini with the country written into every question, 91.1 per cent of the 1,606 sources those answers used were pages on a company's own website. AI Knows Us keeps those readings as the record, which is the same principle as everything above, that a claim is worth what the document behind it is worth.
