If you’re already paying someone to manage your PPC and you’re reading this, the account itself usually isn’t the problem, the relationship is. The part that actually keeps people stuck is the fear that switching will somehow reset months or years of campaign history and send performance back to square one.
That fear is bigger than the real risk, most of the time. In most cases, your PPC campaigns can move to a new manager without losing a single day of history, as long as a few things get handled in the right order and the right sequence.
Will Switching Agencies Reset Your Campaign History?
No, not if the account itself stays the same. Quality Score, conversion history, audience and remarketing lists, and Smart Bidding’s learned performance data all live inside your Google Ads account, not with whichever agency happens to have access to it. Switching who manages that account is closer to changing who holds the keys than starting over with a new one.
The mechanism behind this is called manager account (MCC) linking. Your new agency requests access to your existing account, you approve it, your old agency’s access gets removed, and nothing about the account itself changes in that process. What stays intact when the account itself doesn’t change:
- Your Quality Scores and keyword-level performance history
- Conversion tracking and historical conversion data
- Audience and remarketing lists
- Smart Bidding’s learned performance data
- Campaign structure, ad copy, and account settings
There’s one real exception worth checking now, before you’ve said anything to anyone: this only holds true if the account is registered to your business rather than created inside your current agency’s own manager account.
That happens sometimes, often just for convenience early on rather than anything deliberate, but it means getting the account back can require their cooperation or a support case with Google.
If you’re not sure which situation you’re in, not having admin access to your own account is one of the clearer signs covered in PPC Agency Red Flags to Avoid in New York.
What to Secure Before You Say Anything to Your Current Agency
Before telling your current agency anything, confirm you have admin-level access to your own Google Ads account, then gather your conversion tracking documentation, keyword and negative-keyword lists, audience lists, and a performance history export.
Doing this quietly while the relationship is still active is far easier than requesting it after you’ve already given notice and things have gone cold.
- Confirm you personally have Admin-level access to the Google Ads account, not just the agency
- Document your conversion tracking setup: what’s tracked, and how it’s configured
- Request your current keyword lists, negative-keyword lists, and audience or remarketing lists
- Pull a performance history export or summary, ideally 12 months or more
- Check access to linked accounts too: Google Analytics, Google Tag Manager, and Merchant Center if relevant
None of this requires confrontation. Most of it can be checked and gathered quietly, on your own, before the conversation with your current agency ever needs to happen.
How a Good Agency Handles Onboarding an Existing Account
A properly run onboarding starts with an audit of what’s already there, not a rebuild, and it never involves pausing your campaigns while the paperwork gets sorted out.
Google’s systems relearn from scratch when campaigns go dark or change dramatically, so a good agency makes changes gradually over the first few weeks instead of overhauling everything on day one.
In practice, that looks like the new agency reviewing your existing structure, search terms, Quality Scores, and conversion tracking accuracy before touching anything, then separating quick, low-risk fixes from things that need a more careful, phased approach. Your campaigns stay live the entire time.
If an agency’s onboarding pitch sounds like tearing everything down and starting fresh, that’s a sign they’re planning to rebuild rather than actually manage what you already have.

How Long a Clean Switch Actually Takes
A clean switch, where you already have admin access and the account is genuinely yours, typically wraps up in one to two weeks, covering the access transfer, the billing move, and a short overlap period. A contested handoff, where access has to be recovered first, can add several more weeks on top of that, since Google’s recovery process takes time.
| Step | Typical Timeframe |
|---|---|
| Verify admin access and secure your data | Before you say anything; no fixed timeline |
| New agency’s manager account gets linked | 1–3 business days |
| Billing transfer to the new agency | Up to 7 days |
| Overlap period with both sides watching the account | 1–4 weeks, agency-dependent |
| Full transition, start to finish, cooperative exit | Roughly 1–2 weeks |
| Full transition, start to finish, contested access | Several weeks or more |
What a Responsible Switch Looks Like
A responsible switch is boring on purpose: access and data get requested while the current agency is still active, the new agency audits before changing anything, and nobody leaves a gap where the account isn’t being watched.
What actually causes problems isn’t a bad agency, it’s a rushed handoff, where access gets requested too late or changes happen too fast.
Signs a handoff is being rushed, worth watching for on either side:
- No access handed over before notice is given
- Sweeping structural changes on day one, before anything’s actually been reviewed
- No documented plan for what happens to current campaigns during the changeover
- A stretch where nobody, old agency or new, is actually watching the account
The best protection against a rushed handoff on the new agency’s side is asking about their onboarding process before you sign, not after. That’s part of a broader set of questions worth asking any agency you’re vetting, covered in Questions to Ask Before Hiring a PPC Agency in NYC.
Frequently Asked Questions
Will my campaigns pause or go dark during the switch?
No, not in a properly handled transition. Pausing campaigns is actually one of the more common mistakes in a switch, since Google’s bidding systems relearn from scratch when campaigns go dark or change dramatically, which can hurt performance more than the switch itself would. A good agency keeps campaigns running throughout and makes changes gradually instead.
Do I lose my Quality Score when I switch agencies?
No, as long as the same Google Ads account keeps running. Quality Score is calculated and stored at the keyword level inside your account, not by whichever agency has access to manage it, so relinking the account to a new agency doesn’t reset it. You’d only lose that history by starting a brand-new account
How long does switching PPC agencies typically take?
A cooperative switch, where you already have admin access, usually wraps up in one to two weeks: a few business days to link the new agency, up to a week for billing to transfer, and a short overlap period. If access needs to be recovered from an uncooperative agency first, that can add several more weeks.
What if my current agency won’t give me access to my own account?
Start by requesting admin access and an ownership check in writing, since a documented request is useful even if it’s ignored at first. If the agency still won’t cooperate and the account was built under their own login rather than yours, you may need to escalate to Google Ads support or, as a last resort, rebuild in a new account.
Should I tell my current agency I’m leaving before or after I’ve secured my access?
After, if there’s any doubt about what you actually have access to. Some agencies get slower to cooperate once notice is given, so it’s worth quietly confirming your admin access and exporting your data first, then giving notice once you know exactly where things stand.
Will I lose my remarketing audiences or conversion history?
No, provided the account itself isn’t rebuilt from scratch. Audience lists and conversion history are stored at the account level and move with the account when a new agency gets access, the same way Quality Score and campaign structure do.
Is there a bad time of year to switch PPC agencies?
Switching itself isn’t risky at any particular time, but doing it right before your busiest season adds unnecessary pressure if anything doesn’t go perfectly. Where possible, aim to complete the switch with a few weeks of runway before a seasonally critical period rather than in the middle of one.
What should a new agency’s onboarding process actually look like?
It should start with an audit of your existing account, not immediate changes, followed by a specific plan for what will change and when. If an agency’s pitch focuses entirely on what they’ll build fresh without mentioning what already exists in your account, that’s worth asking about directly before you sign.
