What happens to your marketing when you leave an agency
Most people discover what they own at the worst possible moment, which is the week they decide to leave. It is a twenty-minute check and worth doing while the relationship is good.
The four things that should be yours
If any of these sit in an agency's account, you are renting rather than owning.
- The ad account, with your business as the owner and them as a user
- The domain, registered to you, with the login
- The website files and hosting, in your name
- Analytics and Search Console, as the property owner
Why the ad account matters most
An ad account carries the history — conversion data, audiences, what the algorithm has learned about who buys from you. Rebuilding that takes months and costs real money in worse performance while it relearns.
If the account belongs to the agency, leaving means starting from nothing. Plenty of agencies rely on that without ever saying it.
The website trap
A site built on an agency's platform or hosting, with no access for you, cannot be moved. The practical options become paying to rebuild or staying.
Ask for the hosting login. If there is a reason you cannot have it, that is the answer.
How to check, today
Log into each of the four things above yourself. Not a dashboard the agency gave you — the actual account.
If you cannot log in, you do not own it. That is worth knowing now rather than during a disagreement.
Leaving well
Give notice, ask for access transfers in writing, and check each one has actually happened before the final invoice is paid.
A decent agency will do all of this without friction, because they expected to be asked.
