Performance Max has become Google’s default recommendation for almost every advertiser. Search campaigns remain the workhorse of most profitable Google Ads accounts. Choosing between them, or deciding how to run both, depends on your goals, your data and how much control you need.
How each campaign type works
Search campaigns
Search campaigns show text ads on Google search results when people search for terms related to your keywords. You decide which keywords to target, how closely to match them, which search terms to exclude and what each ad says. Reporting shows the actual search terms that triggered your ads, so you can see exactly where your money goes.
Performance Max
Performance Max (PMax) is a goal-based campaign that runs across all of Google’s inventory from a single campaign: Search, Shopping, YouTube, Display, Discover, Gmail and Maps. You supply assets (headlines, descriptions, images, videos), audience signals and a conversion goal, and Google’s automation decides where, when and to whom ads are shown. Control over placements and search terms is more limited, although Google has gradually added more reporting and exclusion options.
When Search makes more sense
- Lead generation with clear intent: plumbers, lawyers, clinics and B2B services where people search for exactly what you offer.
- Tight budgets: with limited spend, you want every dollar on high-intent searches rather than spread across display and video.
- Limited conversion data: automated campaigns need a reliable volume of conversions to learn. Without it, Search with careful keyword control is usually more efficient.
- Brand and compliance control: regulated industries often need to know exactly which queries trigger ads and what the ads say.
When Performance Max makes more sense
- Ecommerce with a product feed: PMax has largely replaced Standard Shopping as the main way to run Shopping ads at scale, and it often performs strongly for retailers.
- Accounts with solid conversion volume: the more good conversion data Google has, the better the automation performs.
- Reaching new audiences: PMax can find demand on YouTube, Discover and Display that Search alone won’t reach.
- Strong creative assets: good images and video give PMax more to work with across its channels.
Running both together
Many accounts benefit from a hybrid approach: Search campaigns covering core, high-intent keywords and brand terms, with Performance Max layered on for Shopping and broader reach. When an exact search query matches a keyword in a Search campaign, Google generally prioritises the Search campaign, which helps keep your most important terms under direct control. Watch for overlap, though. PMax can claim credit for branded searches and remarketing conversions that would have happened anyway, so consider brand exclusions and judge PMax on incremental results rather than reported conversions alone.
Common mistakes
- Launching PMax with weak or misconfigured conversion tracking, so the automation optimises toward the wrong actions.
- Counting low-value actions (page views, button clicks) as primary conversions.
- Uploading generic stock imagery and a handful of headlines, then expecting strong results.
- Judging performance after a few days, before the campaign has finished learning.
- Letting PMax absorb brand traffic and calling the result growth.
The practical answer
For most service businesses, start with well-structured Search campaigns and accurate conversion tracking, then test Performance Max once you have reliable data and good creative. For most ecommerce businesses, PMax with a well-optimised product feed is the core, supported by Search for brand and key categories.
