Performance Max for Local and Small Businesses: Where to Start

You give Google a goal, such as calls, form fills, store visits or online sales, plus a budget and a set of creative assets: headlines, descriptions, images, logos and videos. Google’s systems decide where to show ads, to whom, and which asset combinations to use. Instead of keywords, you add audience signals that hint at likely customers, and Google treats them as starting points.

For local businesses, the important link is the Google Business Profile. Connecting it lets Performance Max show ads on Maps and in local results, and lets it optimise toward store visits or calls where those goals are available.

It suits businesses that already have conversion tracking and some conversion history, a clear offer, and enough budget for the system to learn. It suits less well a business with no tracking, very small budgets or a single niche service where a few exact search terms do all the work.

A plumber who gets most jobs from people searching “emergency plumber near me” may do better starting with a standard Search campaign. A local gym with good photos, a membership offer and online sign-ups is a more natural fit for Performance Max.

Skipping the basics is the most expensive mistake. Check each of these first:

• Conversion tracking in Google Ads or via Google Analytics 4, counting only valuable actions such as calls over 60 seconds, booked appointments or purchases.
• A complete and verified Google Business Profile linked to the Google Ads account.
• A landing page that loads quickly on mobile and states the offer, location and contact options clearly.
• Enough assets: several headlines and descriptions, landscape and square images, a logo, and ideally a short video.
• Brand exclusions or negative keywords where your account offers them, so the campaign does not just collect searches for your own name.

If you do not provide a video, Google may create one automatically from your images, and the result often looks generic. A simple 15-second phone-shot video usually performs better.

There is no single correct figure, and Google does not publish an official minimum for Performance Max. The practical test is whether the budget allows a reasonable number of conversions each month. If one lead costs, for example, between 20 and 40 in your currency in a typical account, a budget that buys only three or four conversions a month gives the system very little to learn from.

Start with what you can sustain for at least six to eight weeks without changes. Frequent budget swings reset learning and make results hard to read.

Keep the structure simple. One campaign per goal and location area is usually enough for a small business. Inside it, create asset groups by service or product line, for example “teeth whitening” and “dental implants” for a dental clinic, each with its own images, text and landing page.

Add audience signals that reflect real customers: your customer email list, website visitors and custom segments based on the terms people search. Use location targeting with care, choosing “presence” or people regularly in the area where that option is available, so ads do not reach people who only showed interest from far away.

Performance Max gives fewer levers than Search campaigns, but several are worth using:

• Final URL expansion settings, to stop Google sending traffic to unrelated pages such as your blog or careers page.
• Account-level negative keywords or brand exclusions, where available in your account.
• Asset reports showing which headlines and images get impressions and performance ratings.
• Search term insights, which group the searches that triggered ads.
• Channel performance reporting, now available in Google Ads, showing spend by channel.
• Placement reports to spot poor Display and YouTube placements.

Check the search terms monthly. If many are your own brand name, the campaign may be claiming credit for customers who would have found you anyway.

Judge Performance Max on business outcomes, not clicks. Compare cost per qualified lead or per sale against your previous campaigns and against a realistic target. For call-based businesses, record calls and listen to a sample to check quality.

Store visits and local actions, such as direction requests, show up when the profile is linked, but treat them as indicators rather than exact counts. Ask new customers how they found you as a simple second check.

A few errors cause most disappointments:

• Counting page views or button clicks as conversions.
• Running Performance Max alongside a Search campaign for the same terms without understanding which one wins the auction.
• Uploading only one or two images and letting Google fill gaps.
• Judging results after one week.
• Ignoring the Business Profile, which feeds Maps visibility.
