Performance Max vs Search

Short answer

Search campaigns show text ads on Google Search for keywords you choose; Performance Max shows ads across Search, YouTube, Display, Discover, Gmail and Maps from one campaign, with Google choosing placements. Use Search when you need control over which queries you pay for, and add Performance Max when conversion tracking is solid and you want reach beyond the results page.

How the two share traffic

When both campaigns could show for the same search, Google uses a fixed order. A Search campaign with a keyword that exactly matches the query, or is spell-corrected to it, is preferred over Performance Max.[3] For every other match, search themes in Performance Max sit at the same priority as phrase and broad match keywords, and the one with the higher Ad Rank serves.[4]

In practice: the searches you most want to control should be exact match keywords in Search. Everything else is open competition between the two, settled by Ad Rank. Google's keyword page sets the same order, then adds relevance between ad groups as a tie-breaker before Ad Rank.[5]

When Search is the better choice

  • You need to see every query. Search shows the search terms report and lets you block terms with negative keywords. Legal, medical and other regulated advertisers often need that.
  • Conversion tracking is new or unreliable. Search can run on clicks or manual bids while you fix tracking. Performance Max only bids for conversions or conversion value.[1]
  • The budget is small. A few exact and phrase match keywords on high-intent searches can work on a budget that would be spread thin across six channels.
  • Local service businesses whose customers search "near me" style queries usually get most of their leads from Search.

When Performance Max is the better choice

  • Online stores with a Merchant Center feed, because one campaign covers product listings and the other channels.
  • Accounts with steady, accurate conversions, since Smart Bidding bids from them.[2]
  • Advertisers with image and video assets who want YouTube, Discover and Gmail without building separate campaigns.
  • When Search volume is maxed out. If your Search campaigns already win most of the auctions they can, Performance Max reaches people elsewhere.

A common setup that uses both

  1. A brand Search campaign with your brand name as exact and phrase match keywords.
  2. A non-brand Search campaign for your highest-intent searches, with exact match on the terms you want to own.
  3. A Performance Max campaign with brand exclusions turned on, so it doesn't take credit for people already searching for you.[2]
  4. Separate budgets, and a review each week of cost per conversion per campaign, not account totals.

The reason for step 3: brand searches convert well because those buyers already chose you. If Performance Max serves on them, its results look better than the new demand it actually creates.

Common questions

Will Performance Max steal traffic from my Search campaigns?

Only where your Search keywords are not exact matches for the query. Google prefers a Search campaign whose keyword exactly matches (or is spell-corrected to) the search. For other queries, whichever campaign has the higher Ad Rank serves.

Should I run Performance Max and Search together?

Many accounts do: Search with exact and phrase match keywords for the queries that matter most, and Performance Max for the rest of Google's inventory. Add brand exclusions to Performance Max if your brand Search campaign should own brand queries.

Which is cheaper, Performance Max or Search?

There is no fixed answer. Performance Max can show cheaper placements such as Display and YouTube, which often lowers cost per click, but cost per conversion is the number that matters. Compare the two on cost per conversion or ROAS over the same period.

Can I see search terms in Performance Max?

You get search term insights by category rather than the full keyword-level control of a Search campaign. If you need to see and block individual queries, use Search.
