Switching Google Ads Agencies Safely

Changing agency feels like an HR decision. It is closer to a moving day. The campaigns, the conversion tags, the historical data and the bidding models all sit in accounts that someone has to hand over. Whether that handover goes smoothly is decided by one thing: who holds the admin rights on the day you send the email.

Most Malaysian business owners find this out in the worst order. They give notice, feel relieved, then start discovering things. The Google Ads account was created under the agency’s own email. The conversion tags live in a container nobody else can open. Two years of learning data is about to leave with the relationship.

That outcome is common, and it is entirely avoidable. This guide is written by IZI Digital Marketing, and we sit on both sides of these handovers — receiving accounts and, occasionally, handing them back. What follows is the sequence we use to keep a switch boring, starting with whether you should be switching at all.

PART 1 · DIAGNOSE

Should You Switch Agencies or Fix the One You Have?

IN BRIEFSwitch when the problem is capability or honesty. Stay and renegotiate when the problem is scope, reporting or attention. Many accounts we are asked to take over do not need a new agency at all. They need a written scope and a working conversion setup, which we cover in what Google Ads management should include.

Switching costs you weeks. That cost is worth paying when the agency cannot do the job, and wasted when the real fault is a vague agreement that nobody has revisited in two years.

The honest test is whether you can name what has gone wrong in one sentence that describes their work rather than your feelings. “Cost per lead has doubled since March and they have not explained why” is a switching reason. “I never hear from them” is a scope reason, and a scope reason is usually cheaper to fix than to escape.

One more filter before you decide. The signals that justify changing agency are patterns, not single bad months. A quarter of falling performance during a price war in your category is market news. Three quarters with no diagnosis is an agency problem.

PART 2 · DIAGNOSE

Who Actually Owns Your Google Ads Account?

IN BRIEFCheck this before you say anything to your agency. Google Ads sets access at admin, standard, read-only and email-only levels, and only an admin can add or remove other users. If your only company email sits at standard level, you cannot complete a handover on your own — a point we unpack in who should own your Google Ads account.

Open your Google Ads account and look at the users list. Google’s documentation on access levels in a Google Ads account explains what each level can do. You want at least one company-controlled email holding admin, on an address that survives staff turnover.

A linked manager account is a separate matter and often misunderstood. Google notes that when a manager account links to an existing Google Ads account, it does not gain administrative ownership by default. So an agency managing your account through their manager account is normal and fine. An agency that created the account inside their own manager account, with no company admin on it, is the situation you want to correct today rather than on your last day.

Three other systems decide how much of your history survives:

• The analytics property. Google’s access management documentation sets four roles, and only an Administrator can add or remove users. Without that role, you cannot re-grant access to anybody.
• The tag container. Google Tag Manager’s own guidance warns that a single-administrator account can lose access to its tags if that person becomes unavailable. That is why it recommends adding a second administrator. An agency staffer leaving is exactly that scenario.
• The conversion setup. If conversions were configured inside an agency-owned account and imported into yours, the definitions can go when the link goes. Our guide to setting up conversion tracking with GA4 covers how to check the source of each action.

What Has to Transfer When You Change Google Ads Agency?

IN BRIEFSix assets travel in a handover, and each has a different failure mode. The table below assembles what Google’s own documentation says about each one. Work through it in an afternoon, rather than finding the gaps in week three.

Every row below is drawn from official Google documentation, not from agency convention. Work down the list and mark each one confirmed or unknown.

Change history deserves a second look. Google’s documentation states that change history lists changes made to your account, campaigns and ad groups during the past two years. That record is the fastest way for a new agency to see whether performance fell because of the market or because of an edit made one Tuesday afternoon.

PART 3 · DESIGN

How Much Performance Do You Lose During a Handover?

IN BRIEFExpect a dip, and expect it to be caused by the new agency’s changes rather than by the switch itself. Google states that a bid strategy can take up to three weeks, or one to two conversion cycles, to calibrate after a change. Plan around that window instead of judging results inside it.

The dip is real and it has a documented cause. Google’s guidance on the duration of the learning period notes that a bid strategy can take up to three weeks, or one to two conversion cycles, to calibrate. Performance can be more volatile while it does. Restructure a campaign in week one and you have started that clock deliberately.

So the size of your dip is a choice, not a fee. An incoming agency that changes nothing structural for a fortnight while it reads the account produces a smaller dip than one that rebuilds on day two. Both approaches can be defensible; only one of them should be a surprise.

There is also a quieter cost. Whoever takes over needs a month of live data before their reporting means anything, so your first two agency reports will describe someone else’s account. Read them for the diagnosis, not the numbers.

How Long Does a Google Ads Handover Take?

IN BRIEFBudget eight weeks from notice to a stable account, with the softest results falling in weeks three to five. The model below sets out what should be happening each week, so you can tell a normal transition from a stalled one.

The timeline below is an illustrative model built on Google’s published learning-period guidance and a standard one-month notice period. Shift the weeks to match your own contract.

Notice where the low point sits. It arrives after the new agency starts working, not when the old one leaves, which is why owners so often blame the wrong week.

The Safe Sequence for Switching Google Ads Agency

IN BRIEFOrder matters more than speed. Secure access, export the record, appoint the replacement, overlap the two agencies briefly, then remove the old access last. Reversing any two of those steps is where switches go wrong, and the reversal is almost always emotional rather than practical.

Here is the sequence we use, and the reasoning behind each step:

1. Confirm admin access on all four systems. Ads account, analytics property, tag container and payment profile, on a company email nobody else controls. Do this quietly, before the conversation.
2. Export the record. Change history, twelve months of campaign and keyword performance, conversion action settings, and a list of every active landing page. You want this while the account is still calm.
3. Appoint the replacement first. Never give notice into an empty chair. A gap of even three weeks with nobody watching spend is more expensive than a fortnight of overlap.
4. Give notice in writing, and keep campaigns live. State clearly that campaigns are to keep running through the notice period. Ask for a handover call and a written note of anything in flight.
5. Add the new agency while the old one still has access. An overlap of one to two weeks lets questions be answered by the people who know the answers.
6. Remove the old access last, and check nothing broke. Then watch conversions for 48 hours. If a tag was firing from the old container, this is when it stops.

Two of those steps get skipped most often. Owners give notice before appointing a replacement because the relationship has become uncomfortable, and they remove access immediately for the same reason. Both feel decisive. Both cost money.

What Does a Rushed Agency Switch Cost?

IN BRIEFThe bill for a badly run switch is paid in lost enquiries, not in fees. The model below prices four switching styles on the same monthly spend, and the gap between the best and worst is larger than most management fees in Malaysia.

All four rows assume the same account and the same monthly budget. Only the handling changes.

The distance between the top and bottom rows is not talent. It is access and patience — two things you control before the new agency does anything at all. That matters in a market where micro, small and medium enterprises contributed 39.5 per cent of Malaysia’s GDP in 2024, and where most of those businesses cannot absorb a quiet quarter.

PART 5 · DRIVE

How Do You Make the Next Switch Easier?

IN BRIEFWrite the exit into the new agreement while everyone is still pleased with each other. Four clauses do almost all the work, and a capable agency will sign them without argument — the reaction to the request tells you as much as the clauses do.

Negotiate these before the first invoice, alongside the wider terms covered in our guide to digital marketing contract terms worth negotiating:

• Accounts are created in your name. The ads account, analytics property and tag container belong to your business, with the agency added as a user.
• Company admin is permanent. One company email keeps admin rights on every system throughout the engagement, and it is not the account manager’s.
• Creative and landing pages transfer on exit. Ad copy, images and any pages built for your campaigns are yours, in editable form.
• A defined handover window. Thirty days of continued access after notice, campaigns running, one handover call included.

Ask for these during the shortlist stage rather than after signing. If you are still comparing options, our review of Google Ads agencies in Malaysia sets out what to test, and the same access questions apply if you are also weighing organic work through an SEO agency shortlist.

Which Handover Gaps Cause the Most Damage?

IN BRIEFNot every gap hurts equally. A missing tag container is recoverable in days; a rebuilt account loses years of history permanently. The grid below ranks the five common gaps by how often we meet them and how long each takes to repair.

Read this as a priority order for your access audit. Fix the bottom rows first.

The pattern is consistent. Gaps that only need cooperation resolve quickly. Gaps that destroy history never fully resolve, because no amount of good work rebuilds a record of what already happened.

FAQ

Common Questions About Switching Google Ads Agency

1. Can my agency stop me taking my Google Ads account?

Not if you hold admin access on the account. It depends entirely on whose email sits at admin level, because only an admin can add or remove other users. Check that today, since the answer changes what your notice email should say.

2. Should I pause campaigns while I switch?

No, keep them running unless there is a live billing problem. It depends on whether anyone is watching spend, so if there will be a true gap with no oversight, reduce budgets rather than pausing. Pausing restarts learning you have already paid for.

3. Will I lose my conversion data when I change agency?

Only if the conversion actions live in an account you do not control. It depends on how the tracking was set up, because imported or shared conversions can disappear with the link. Confirm where each action was created before notice is given.

4. How long before the new agency should be judged?

Give it eight weeks, and set the date in writing at the start. It depends on your conversion volume, since Google’s own guidance allows up to three weeks for bidding to recalibrate after changes. Judging at week four measures the transition, not the agency.

5. Is it better to switch agencies or move to a different channel?

Switch first if the channel itself still suits your customers. It depends on whether people search for what you sell, a comparison we work through in where leads come cheaper between Google and Meta. Changing channel and agency at once leaves you unable to explain either result.

THE VERDICT

Do the Boring Check Before the Difficult Conversation

Switching Google Ads agency is not risky in itself. It becomes risky when the decision to leave is made emotionally on a Friday and the access audit happens the following Monday, by which point your leverage has gone and the account is already someone else’s problem.

So reverse the order. Spend ten minutes today confirming that a company email holds admin rights on the ads account, the analytics property and the tag container. If it does, you can change agency whenever you like, at the cost of a few soft weeks. If it does not, fix that first — and treat the answer as information about the relationship you are already in.
