How to pick a Google Ads bid strategy on a small budget

Say you run a garage door company in Hayward. This is a made-up example. A while back you started a Google Ads campaign, picked “Maximize conversions” because the name sounded right, and let it run. Now you’ve read that Google changed how bid targets work this summer, you can’t remember whether your phone calls were ever being counted, and you’re not sure which of the strategies in the dropdown is meant for an account your size.

Bid strategy is the setting that tells Google how to spend your budget on each click. For a small account, the right choice comes down to one question: how many real leads does Google Ads actually see you getting? The rest of this post is how to answer that, and what to pick for each answer.

Which bid strategies can you choose from now?

Google’s automated bidding page lists the options by goal. These are the ones that matter for a local service business:

• Maximize clicks gets as many clicks as it can within your budget. Google lets you set a maximum cost per click so it can’t overpay for any one click. It treats mobile and desktop clicks the same, even though they often convert differently.
• Maximize conversions uses Google’s AI to get as many conversions as it can. Google says it aims to spend your average daily budget, and that you must have conversion tracking set up to use it.
• Target CPA does the same job but aims for an average cost per conversion that you choose.
• Maximize conversion value and Target ROAS are the same ideas for businesses that record a different value on every conversion. Google says to have “two or more differentiated values” first. If every call and form counts as one conversion on your account, skip these.
• Manual CPC means you set the bids yourself. It still exists, but it takes steady attention, and most owners don’t have the hours.

Two naming changes can trip you up if you’re working from an older guide:

• Enhanced CPC is gone from Search and Display campaigns. Google’s page says it ended the week of March 31, 2025, and that campaigns not moved to another strategy are “now effectively using Manual CPC.” If you set up your account years ago and never looked, check.
• Target CPA has a new label. Starting in June 2026, “Maximize conversions with a Target CPA” is simply “Target CPA.” Google says it works the same way and the change is only visual.

Why does conversion tracking come before the strategy?

Every conversion-based strategy learns from your conversions. Google’s Maximize conversions page says it plainly: you must set up conversion tracking to use it. If Google Ads can’t see which clicks turned into leads, a smarter strategy has nothing to learn from.

For a contractor, the lead is usually a phone call or a form. Google’s call tracking page separates three things worth knowing:

• Calls from your ads, through Google’s call assets.
• Calls to the number on your website, which need Google’s forwarding number and the Google tag on the site.
• Taps on a phone number on your mobile site. These count the tap, not the call. Someone can tap and hang up.

You also set a minimum call length, and calls shorter than that don’t count. If your calls aren’t being recorded, a minimum that’s too high for your business is one thing to check.

Then check which conversions are primary. Per Google’s page on primary and secondary conversion actions, primary actions are used for bidding and secondary ones are observation only. A form submission and a qualified call should be primary. A page view should not be. If the wrong things are primary, the bidding system optimizes toward the wrong thing.

A quick test: open the Conversions column for the last 30 days and compare it with the calls and forms you know came from your ads. If the two don’t roughly match, fix that before you touch the strategy.

Which strategy fits your account?

Count your conversions for the last 30 days, then find yourself below. The cutoffs come from Google’s own guidance where it gives one, and from my own judgment where it doesn’t. I say which is which.

You have no tracking yet, or almost no conversions. Maximize conversions and Target CPA have little to learn from. Google says you can start Target CPA with no conversion history, but there is nothing for it to work from yet. Use Maximize clicks with a maximum cost per click while you fix tracking. This is my rule of thumb, not Google’s: treat it as a few weeks’ holding pattern, because clicks are not jobs.

You have a handful of conversions a month. Use Maximize conversions with no target. Google doesn’t publish a minimum number of conversions for this strategy. It does say the strategy aims to spend your full average daily budget, so set a daily budget you’re comfortable spending every day, not one you hope it won’t reach.

You have steady conversions. Move to Target CPA. Google says to evaluate it on the last 30 days, “including at least 30 conversions,” and to base the target on your average cost per conversion over that period. Google also says it doesn’t calculate recommended targets for campaigns with fewer than 7 conversions, so below that you’d be guessing.

What changed on August 17 for Target CPA?

If you use a target, read this part. Google changed how Target CPA and Target ROAS behave for campaigns that are limited by budget. Before, a campaign that was beating its target could keep doing better than the target. Now Google steers it closer to the target you entered. Google’s own example: a campaign with a target of 10 and a recent actual cost of 5 would now deliver closer to 10. The rollout began August 17, 2026 and, per the FAQ, finished August 27.

In plain terms: a target that is looser than your recent results will pull your cost per lead up toward it. Google doesn’t change your targets or budgets for you. Its options are to keep your target, set it to match recent results, set a new one, or switch to Maximize conversions if you’d rather keep volume (your cost per conversion then moves with your budget). Manual CPC and Target impression share are not affected.

If you set a Target CPA, set it near what you’ve actually been paying, not what you wish you paid.

What does “learning” mean in practice?

Google’s page on primary and secondary conversions says Smart Bidding strategies “require a standard 7-14 day learning phase,” and that changing budgets, targets or conversion goals during it resets the window. In practice that means one change at a time, then leave it alone.

Give it the same patience on the other end. If your leads usually book a few days after the click, Google’s FAQ says to wait one to two conversion cycles before you judge a change. A Tuesday verdict on a Monday change is noise.

When should you move to the next strategy?

Move when the data supports it, one step at a time:

• Maximize clicks to Maximize conversions once tracking has run for a month and the conversion count matches the calls and forms you know about.
• Maximize conversions to Target CPA once the last 30 days include at least 30 conversions, and you have a target you can set from your own numbers.
• Back down a step if conversions dry up after you add a target. A target that’s too tight starves the campaign. Raise it or return to Maximize conversions.

Whatever you pick, judge it on booked jobs, not on Google’s conversion count. A conversion is Google’s number. A job is yours. A strategy that doubles form fills and books the same number of jobs hasn’t improved anything.

What to do about it this week

1. Open the Conversions column for the last 30 days and compare it with the calls and forms you know came from your ads.
2. Check your call conversion settings: which actions are primary, and what minimum call length you set.
3. Count your conversions for the last 30 days.
4. Pick by the count: none or almost none, Maximize clicks with a cost per click limit while you fix tracking; a handful, Maximize conversions; 30 or more, Target CPA set near your recent average.
5. Look at the campaign status. If it says “Limited by budget,” set any target to match recent results, not a hopeful number.
6. Make one change, write down the date, and leave it alone for two weeks.
7. After a month, compare booked jobs with the month before.

If you also run Local Services Ads, they’re moving into Google Ads too, as a campaign with its own single Target CPA. Here’s what to do before that switch. And if you’d rather not babysit any of this, day-to-day account management is part of our digital advertising work.
