Is your account ready for it?
Performance Max hands Google control over where your ads appear and who sees them, so the quality of what you feed it decides everything. It learns from the conversions you report. A business with a steady stream of tracked enquiries gives it plenty to work with. A seasonal farm stand with a handful of enquiries each month gives it very little, and the campaign can wander.
Be honest about budget too. When the daily spend is small, Google gathers its learning slowly and every click matters more. In that situation, a well-built Search campaign, or Local Services Ads if you are a trade, usually earns its place first. Performance Max can follow once the basics bring in leads steadily.
Where local lead campaigns go wrong
The usual failures are predictable. The campaign claims credit for people who were already searching your business name. It shows ads to people outside your service area who merely take an interest in Abbotsford. It treats a ten-second call or a spam form as a win, then goes looking for more of the same.
A roofer in Clearbrook can wake up to a month of enquiries from another province. A clinic can pay for page-view conversions that never turn into bookings. None of this is a flaw in the technology. It is what happens when the instructions reward the wrong thing, which is why the next section matters.
Fix these before you launch
Most of the work happens before the campaign exists. Check that every conversion action fires correctly, and that a test form and a test call each appear in the account. Spend an afternoon on this, not five minutes.
Then shape the inputs. One tangled asset group that mixes all your services teaches Google very little. Separate groups for drain repair, furnace installs or each treatment let it match the message to the search, and show you which service is working. If you skip video, Google may assemble one from your photos, and it is rarely your best work.
- Count only meaningful conversions: calls above a minimum length, completed forms and bookings
- Set locations to people in your service area, not people merely interested in it
- Add brand exclusions and a shared negative keyword list for jobs and areas you do not serve
- Build one asset group per service, with real photos, short headlines and a video if you have one
- Add a customer list or past website visitors as an audience signal
Run it beside Search, not instead of it
Keep a Search campaign on the phrases that matter most, such as emergency work or a named treatment, because Search shows you exactly what you appear for. Add Performance Max as a second campaign with its own budget and a clear start date. Where a search matches a keyword in your Search campaign exactly, Google tends to favour that campaign, so some overlap is normal.
Give the test a fixed window of about eight weeks. Changing budgets, assets and goals every few days restarts the learning and muddies the result. Write down the start date, what counts as a lead and what cost per lead you would be happy with before you look at any numbers.
Judging the results without fooling yourself
Google reports where Performance Max spent through channel and search-category views, with less detail than Search gives you. Use them to spot obvious waste, not to micromanage. The only verdict that counts is whether real jobs, bookings or sales came from the campaign, so match its leads against your phone records and your booking list every week.
If after eight weeks the leads are real and the cost is acceptable, hold steady and add one improvement at a time, such as a fresh video or a new service group. If the leads are poor, check tracking and location settings before you blame the format. If both are right and results still disappoint, pause it without guilt.
Where Google’s ad tools are heading
Google keeps folding more of its advertising into goal-based campaigns, where you supply objectives, data and creative and the system chooses the rest. That raises the value of clean conversion tracking and honest photography, and lowers the value of fiddling with bids. The advantage will belong to businesses that know which leads are worth paying for.

Questions & answers
There is no fixed number that suits everyone. The budget needs to be large enough to produce a steady flow of tracked conversions during your test window. Work backwards from the cost per lead you can afford to the number of leads you need, and check that the maths holds before launch.
It can. Performance Max covers Search, Maps, YouTube, Display, Gmail and Discover, and Google chooses the mix. Linking your business location helps it show your address and call button. Check the channel report to see where spend went, and judge the campaign by leads rather than placements.
Not necessarily. Use brand exclusions to stop it bidding on your own name, then compare results before and after. If your Search campaign already captures branded traffic cheaply, you want Performance Max to find new people rather than recycle customers who already know you.
Expect a learning period of a few weeks, during which results swing. Judge the campaign at around eight weeks on leads you can verify, not on dashboard clicks. Shorter windows mislead, and constant tinkering restarts the learning. A free marketing audit can check your tracking first.
