Switching Google Ads agencies works cleanly when the handover is treated as an asset transfer. The account you've been running has months or years of conversion data, learned bid signals, keyword history, and quality score built into it. A good transition preserves all of that so the new team starts from your actual performance baseline. If you're researching how to switch google ads agencies without losing performance, the mechanics below are what protect the work you've already paid for.
For the complete picture, see our The Complete Guide to Vetting a Family Law PPC Agency.
Most performance drops after an agency switch trace back to three things: lost account access, broken conversion tracking, or a full rebuild when migration would have worked. All three are preventable with the right sequence.
Here's the step-by-step handover that keeps your campaigns performing through the transition.
Own the Google Ads Account Under Your Own MCC
Your firm should be the registered owner of the Google Ads account, with the agency granted manager (MCC) access. This is the single most important structural decision in any agency relationship, and it's where switching gets painful if it was set up wrong.
Check your account under Admin, then Access and Security. If the account ID starts with the agency's manager account and your firm has no direct login, you have an ownership problem to resolve before anything else moves. The fix is straightforward: create a Google Ads account owned by your firm's email, then have the current agency link their MCC to yours as a manager.
Confirm these specifics before you give notice to the current agency:
- The Google Ads customer ID is registered to a firm-owned email, ideally a shared inbox like ads@yourfirm.com
- At least one admin-level user at the firm has direct standard or admin access
- Billing is set up under the firm's payment method, not the agency's
- Google Analytics 4, Google Tag Manager, and Google Business Profile are all owned by firm emails with admin access
If billing runs through the agency, you'll also need to reconcile how spend has been invoiced and switch the payment profile before the new team takes over. Agencies that charge a percentage of spend sometimes route billing through their own account for convenience. That setup requires an extra step at handover.
Preserve Conversion History and Tracking Setup
Conversion data is the single most valuable thing in your account. Smart Bidding strategies rely on it. Historical performance comparisons depend on it. Lose it, and the new agency is effectively starting from zero on bid optimization, even if the campaigns themselves stay intact.
Document every conversion action currently firing in the account before the switch. For most family law firms, that includes phone call conversions from ads, phone call conversions from the website, form submissions from the consultation request page, and sometimes chat engagements. For each one, record where the tag lives (Google Tag Manager container, hardcoded on the site, or inside a call tracking platform like CallRail), who owns the account it reports to, and the conversion value or category assigned to it.
Keep the same conversion actions firing from the same sources through the transition. The new agency can audit and improve tracking after the handover. Changing tag IDs, swapping call tracking providers, or rebuilding the GTM container during week one is how firms accidentally reset their learning history.
If your current agency used their own call tracking subscription, that number pool and all its historical call data goes away when the contract ends. Transition to a firm-owned call tracking account before the switch, port the numbers if possible, and run both setups in parallel for a week to confirm the new one is capturing everything.
Migrate the Account Instead of Rebuilding From Scratch
A healthy account with conversion history, quality score, and a mature negative keyword list is worth preserving. The right question to ask a prospective agency is how they'd approach the first 30 days of your specific account, with current performance data in front of them.
Migration preserves campaign IDs, ad group structures, conversion history, and Smart Bidding learning. The new agency can audit the structure, pause what isn't working, add new campaigns, refine negatives, and test new ad copy, all without erasing the account's performance signal to Google's algorithms.
Rebuilding from scratch is appropriate in a few specific scenarios: the account structure is genuinely broken (think one campaign with 400 keywords and no ad group logic), conversion tracking has been firing incorrectly for months and the data is unreliable, or the account has accumulated so many policy strikes and disapprovals that a clean start is faster than remediation. Outside of those cases, migration is the lower-risk path.
Ask the incoming agency directly: what in the current account will you keep, what will you change in the first 30 days, and what will you leave alone until you have 60 days of your own data? A specific answer signals they've looked at the account. A generic "we'll rebuild everything our way" signals they haven't.
Run a Structured Handover Window
Give the transition two to three weeks of overlap when possible. The outgoing agency keeps the account live and performing while the incoming agency gets access, audits what's there, and prepares their first set of changes. This window is where most of the value protection happens.
Use this handover checklist during the overlap period:
- Account access confirmed. New agency has manager-level access to Google Ads, Google Analytics 4, Google Tag Manager, Google Business Profile, and the call tracking platform.
- Conversion tracking verified. New agency has tested every conversion action, confirmed it's firing correctly, and documented the full tracking stack in writing.
- Historical data exported. At minimum, 12 months of search terms, keyword performance, ad performance, geographic performance, and conversion data pulled and saved as a baseline reference.
- Negative keyword list captured. The current negatives at both account and campaign level exported, so nothing is accidentally lost during cleanup.
- Landing page and form access handed over. New agency has CMS access to the pages ad traffic sends to, and can see form submissions in whatever platform receives them.
- Billing updated. Payment profile under firm ownership, invoicing arrangement with new agency documented.
- Reporting baseline agreed. New agency commits to the specific metrics they'll report on (consultations booked, cost per lead, qualified lead rate, spend) and the cadence.
- Change log opened. New agency documents every structural change made in the first 60 days so you can trace performance shifts back to specific decisions.
Set a hard cutover date and stick to it. Dragging the handover across two months creates ambiguity about who's responsible for what, and that's when things fall through the cracks.

Set the Performance Baseline Before Changes Begin
Export the last 90 to 180 days of account data as a frozen reference point before the new agency touches anything. This becomes the comparison you'll use to evaluate the switch. Without it, you'll be relying on memory and screenshots when you try to answer the question "is this actually better."
The baseline should include spend, impressions, clicks, click-through rate, conversions, cost per conversion, and the share of conversions that became booked consultations. If your intake team tracks lead quality, include that too. Impression share and search impression share lost to budget are useful diagnostics for understanding whether the account was constrained by budget or by bid.
Give the new agency 60 to 90 days before judging the switch. Google's bidding algorithms take two to four weeks to recalibrate after meaningful changes, and family law has enough variability week to week that short windows are misleading. Agree on the review date in writing when you start, and use the frozen baseline as the comparison.
A quick ORSA note: when we take over a family law account, the first week is spent on access, tracking verification, and a full audit of the existing negative keyword list and search terms report. We publish the audit findings and a 30 day plan before changing bids. You can see how we structure engagements on our services page.
Performance survives an agency switch when account access, conversion history, and tracking all transfer properly. The checklist above protects the asset you already paid to build, so the new team starts from your real performance baseline and the first 90 days are spent improving the account rather than reconstructing it. Treat the handover with the same rigor you'd apply to any client file transfer at your firm, and the transition becomes a step forward instead of a reset.
Before you give notice to your current agency, run through the ownership and tracking checks in the first two sections of this guide.
