How to Switch Google Ads Agencies Without Losing Your Data

By Jason Stern  ·   ·  Founder, Enlightened Media (Google Premier Partner)

To switch Google Ads agencies without losing data, make sure your business has admin access to the account, then link the new agency's manager account before removing the old one. Campaigns, history and conversion data live inside the Google Ads account itself, so if you keep the account, you keep the data. The real risk is when the agency owns the account.

Step one: find out who owns the account

Before you give notice, log in to Google Ads and check where you stand. Go to Admin, then Access and security. The Users tab shows who has access and at what level. The Managers tab shows which manager accounts are linked to yours.

You will be in one of three situations:

  • You own it. Your business email has admin access, your payment method is on the payments profile, and the agency is linked as a manager. This is the easy case.
  • You have access, but not admin. Ask the current agency to upgrade your user to admin before anything else. It is a quick change on their side.
  • The agency owns it. The account was created under their login, billed to their payment method, or you have no login at all. You will need to ask for admin access, and the best time to ask is before you announce you are leaving.

Read your contract too. Some agency agreements say the account or the campaigns belong to the agency. Know what you signed before that conversation.

Why keeping the same account matters

Google Ads stores everything inside the account: campaign settings, keyword and search term history, change history and every conversion your tracking recorded. Smart Bidding strategies like target CPA learn from that conversion history.

If you have to start a fresh account, none of that comes with you. Campaigns can be rebuilt, but bidding starts with no conversion data and you lose the long-term record of what worked. In the accounts I have taken over, keeping the existing account has been the smoother path whenever admin access was available, even when the old build needed heavy cleanup.

If the old agency will not hand over access, a new account is not the end of the world. It means a slower first stretch while new data builds.

Everything else to secure besides Google Ads

The Google Ads account is only one piece. Lead tracking usually runs through other tools, and this is where data quietly gets lost:

  • Google Tag Manager: make sure you are an admin on the container that fires your conversion tags.
  • Google Analytics 4: get admin access to the property and confirm it is linked to Google Ads.
  • Call tracking: if the agency set up tracking numbers in its own call tracking account, ask how those numbers can move to an account in your name. If they are shut off, calls from your ads and website can stop connecting.
  • Landing pages: if your ads point to pages the agency hosts, those pages may go offline when you leave. Know where your final URLs point.
  • Google Business Profile and Merchant Center: confirm you are the owner, not just a manager.

If you are not sure what fires where, a conversion tracking review is worth doing as part of the switch.

What to export before the old agency leaves

If you keep the account, most of the history stays put. Still, save a few things for your own records:

  • A full account export from Google Ads Editor (Google's free desktop app), which captures every campaign, ad group, keyword and ad
  • Monthly performance reports by campaign for at least the last 12 months
  • A search terms report and your negative keyword lists
  • A list of conversion actions and which ones are set as primary
  • Past reports, notes or strategy documents the agency sent you

If you are moving to a new account, these exports matter even more. An Editor export lets you recreate the structure without starting from a blank page, though history and bidding data do not carry over.

How to time the handoff

The goal is no gap in management and no stretch where two agencies are editing the account at once.

  • Choose the new agency first. See how to hire a Google Ads agency for what to check.
  • Secure admin access and the other tools above before giving notice.
  • Give notice according to your contract. Month-to-month terms make this simple.
  • Have the new agency send a link request from its manager account, and accept it under Admin, Access and security, Managers.
  • Agree on a cutover date. On that date, unlink the old agency's manager account and remove any individual logins they had.
  • Keep campaigns running through the switch. Pausing everything costs you leads for no reason.

If you can, avoid switching right before your busiest season. The first few weeks with a new manager carry the most change, and you want that window to land when a dip would hurt least.

The first 30 days with a new manager

A good new manager does not tear everything down on day one. In the accounts I take over, the first month usually looks like this:

  • Week 1, audit and tracking: confirm conversions fire correctly and count only real leads. Nothing else matters if tracking is wrong.
  • Weeks 1 to 2, stop the waste: add negative keywords from the search terms report and fix settings like overly broad locations or unwanted networks.
  • Weeks 2 to 4, structural changes: rebuild campaigns or ad groups that need it, in stages, so bidding is not relearning everything at once.
  • End of month, baseline report: leads, cost per lead and what changed, compared with the period before the switch.

Expect some movement while bid strategies adjust. Judge a new manager on direction over the first couple of months, not the first week. At Enlightened Media onboarding takes about 7 days and there are no setup fees, so the first month goes to the work itself.

Frequently Asked Questions

Will I lose my data if I switch Google Ads agencies?

Not if you keep the same Google Ads account. Campaigns, history and conversion data live in the account, not with the agency. You lose that history only if the agency controls the account and you have to start a new one. Secure admin access to Google Ads, Tag Manager, Analytics and call tracking before you give notice.

How do I remove an agency from my Google Ads account?

As an admin, go to Admin, then Access and security. On the Managers tab, unlink the agency's manager account. On the Users tab, remove any individual logins from the agency. Do this on an agreed cutover date, after your new agency's link request has been accepted, so the account is never left unmanaged.

Can an agency refuse to give me my Google Ads account?

If the agency created the account under its own login, it controls access, and what happens next depends on your contract. That is why ownership should be settled before you sign. If access is refused, you can build a new account and recreate the campaigns, but conversion history and bidding data do not transfer.

How long does it take to switch Google Ads agencies?

The access and link changes take minutes once everyone cooperates. Most of the time goes to contract notice periods and onboarding. At Enlightened Media onboarding takes about 7 days. Expect a few more weeks before performance settles, since bid strategies go through a learning period after significant changes.

The Bottom Line

Switching agencies is mostly an access problem. If your business owns the account and the tools around it, you keep your history and the new manager starts with real data. I personally manage every account at Enlightened Media, and clients always own their account and data.
