An independent agency's book of business is its most valuable list. Hundreds or thousands of households, each with a policy that renews, an address, a phone number and an email. Google offers a way to upload a list like that and show ads to the people on it, or to people who resemble them.
Most agencies can't use the targeting half of that tool. Google sets a spending threshold for it that the average agency's entire marketing budget wouldn't reach for years.
That threshold matters most in the campaign Google built to use every signal it can get: Performance Max. This chapter covers when an agency should start Performance Max, how we keep it from taking credit for searches the other campaigns already win, and what an agency can do with its client list before it ever reaches $50,000.
An Agency Spending Its Whole Marketing Budget on Google Would Need More Than Two Years to Unlock Customer Match Targeting.
Chapter 2 sized the average independent agency's marketing budget from the Big "I" survey of agencies: $20,600 a year in 2026. The same survey shows it up from $14,300 in 2024. That figure covers every channel, and Facebook is the social platform most agencies use, at 70%.
Google's Customer Match policy splits advertisers in two:
- Every advertiser in good standing can upload a customer list and use it for observation, which means reporting on how those people respond, and for exclusions.
- Showing ads to the households on that list, or bidding more for them, is reserved for accounts with three months of history and more than $50,000 of total spend.
Run the math. An agency that put its entire $20,600 into Google Ads would pass $50,000 about two years and five months in. One that splits the budget with Facebook, mailers and sponsorships gets there much later, if ever. At $3,000 a month in clicks, an agency crosses the line in about 17 months.
So what can a smaller agency do with its list? Two useful things.
First, exclude current clients from campaigns built to find new ones. An existing auto client who searches "car insurance quotes" to check your rates shouldn't cost you a new-client click. In a Search campaign, a customer list added as an exclusion keeps those clients out of the audience. Performance Max has its own route: the customer acquisition goal set to bid only for new customers. It uses your uploaded lists to tell new households from existing ones. Google's lifecycle-goal setup asks for lists with at least 100 active members.
Second, use only data you collected yourself. Google's policy allows uploads of information customers gave you directly, such as through your website or your office. Agencies have one more check to run. Our reading is that client lists count as nonpublic personal information under the federal Gramm-Leach-Bliley Act, and that Google can receive them as a service provider marketing your own products if two things are true: your privacy notice discloses the sharing, and a contract binds Google to keep the information confidential. Have that notice and those terms reviewed before you upload a single email address.
Performance Max Learns From Conversions an Agency Doesn't Have in Month One. It Waits for 30 Quality Conversions a Month.
Performance Max is Google's one-campaign-everywhere option. A single campaign can place an agency's ads on Search, YouTube, Display, Discover, Gmail and Maps. The agency supplies the quote goal, the money and the creative; Google picks the placement, the bid and the mix for every impression.
Every one of those choices is trained on conversion data, and that's the problem for a new agency account. In its first weeks, an agency has no quote requests on record for Google to learn from, which is why we never launch Performance Max on day one. It waits for the same gate broad match waited for in Chapter 6: roughly 30 quality conversions a month, meaning real quote requests and calls long enough to be conversations, with Isolation and Exploration both running. For most agencies that's around months 6 or 7. Busier ones get there sooner.
An agency's first Performance Max campaign gets three settings:
- The goal is conversions, not conversion value. Most agencies can't yet send Google a reliable value for each new household, so Google would be guessing at it.
- No target cost per conversion at launch. Performance Max needs room to learn. A target can come later, set from its own results.
- One campaign, built around the agency's strongest line. If home and auto quotes make up most of your conversions, that's where Performance Max starts.
Your Exact Match Keywords Outrank Performance Max on Identical Searches. Isolation Keeps the Quote Searches It Already Won.
An agency owner's first question is usually whether Performance Max will steal the quote searches Isolation spent months proving. As long as Isolation's exact keywords can serve, the best of them stay put.
Google ranks the campaigns that could answer a search, and the top rank belongs to a Search campaign's exact keyword that matches the search word for word. It beats every broad and phrase keyword in the account, and it beats Performance Max, as long as that exact keyword is eligible to serve. So if Isolation holds [home insurance agent near me], has budget left and targets the searcher's area, an identical search goes to Isolation, at Isolation's bid, with Isolation's ad. Google notes two exceptions worth knowing: a keyword held back by a tight budget or narrower targeting loses that priority, and searches that start in Google Lens, AI Mode, AI Overviews or autocomplete may not be matched the same way.
That's one more reason Chapter 6 kept the proven quote searches in exact match. They stay in the campaign you control, and Performance Max works the rest: the wordings you haven't listed, plus YouTube, Gmail and Discover, where Search campaigns don't run, and more of Maps than your location assets reach.
A Client Who Misspells Your Agency's Name Can Land in Performance Max. A Brand Exclusion Sends Them Back to the Brand Campaign.
Your agency's name is the easiest search in the account to convert. Someone typing it already knows you. If Chapter 9's brand campaign holds the name in exact match, an identical search goes there. But people type the name a dozen ways, with a town, a misspelling or a producer's name, and Performance Max is built to find conversions. Without a fence, it shows for those variations and counts the results as its own.
That has two costs. Chapter 9's agency-name campaign gives up clicks that cost almost nothing, and Performance Max reports a flattering cost per quote built on people who were already coming to you.
Google's fix is brand exclusions. Brand lists draw on Google's library of brands, and a small agency often isn't in it yet. If yours isn't, request that it be added; producer names may not qualify. Once the list exists, attach it to the campaign. For this campaign type, it blocks those names on Google Search, Shopping and searches inside YouTube. Then add the common misspellings and town versions of the name to the brand campaign as keywords, so the searches the exclusion blocks still have an ad to land on. Captive agents should check how the carrier's brand is handled before adding it, since Chapter 15 covers the carrier's own rules.
Final URL Expansion Can Send a Quote Shopper to Your Claims Page. Turn It Off or Exclude Every Page That Isn't a Quote.
Performance Max doesn't only choose where the ad shows. It can also choose which page of your site the click lands on. Google calls this Final URL expansion, and its help page says it's on by default. The same page says that turning it off "can help prevent your campaign from using unexpected URLs."
An agency website has plenty of pages no shopper should land on from an ad:
- Claims and "report a claim" pages, written for current clients.
- Make a payment and client login pages.
- Careers pages, which draw job hunters.
- Medicare and health pages, unless the agency holds Google's certification to advertise health insurance. Chapter 14 covers that process.
We usually turn expansion off at launch and point each asset group at the line page it was built for, the same pages Chapter 4 built. If you leave expansion on, add URL exclusions for every page on that list. Seven days in, open the landing page report and confirm every click reached a quote page, not the claims form.
Audience Signals Are Hints, Not Targeting. The Searches Your Clients Typed Make Better Hints Than a Demographic Box.
Performance Max asks for audience signals: lists, interests and searches that describe your ideal customer. Google is clear that they're suggestions. Google's own help page warns that the campaign can go beyond the signals whenever it expects someone outside them to convert.
So the signal's job is to give Performance Max a good starting point. The best one an agency has is free and already in its account: the search terms that turned into quote requests in Isolation and Exploration. Google itself recommends custom segments built from search terms. A segment of "home insurance quote," "homeowners insurance near me" and "bundle home and auto insurance" tells Performance Max far more than an age range and a household income box.
A second custom segment can use competitor websites, up to 20 of them. In insurance, that means comparison sites and lead sellers whose visitors are shopping for coverage right now. This is profiling, not remarketing: Google uses those sites to understand who's shopping, not to follow their visitors around.
Video matters too. Performance Max shows on YouTube, and Google's video page says that if you don't supply a video, it will create one automatically when possible. A 30-second clip of a real producer explaining how they shop a policy beats anything assembled from your logo and stock photos. It doesn't need a studio. A phone on a tripod in the office, good light from a window and one clear sentence about what the agency does for a family are enough. Shoot one version for each orientation Google asks for, horizontal, square and vertical, so it doesn't stretch or crop your clip to fit.
Next: Google Has a "Purchasing a Home Soon" Audience. Demand Gen Reaches Them Before They Shop for Home Insurance.
Performance Max finds buyers who are ready now. Chapter 11 covers a campaign built to reach people a step earlier, while they're still buying the house. Earlier chapters cover exact match before broad, license-first settings and a page for every line. Every chapter is on the guide's home page.
Our Google Ads management builds Performance Max for agencies once their accounts are ready for it. Doing it yourself? List every page on your site and mark the ones a quote shopper should never see.
