- By unlocking net-new searches using broad match and keywordless technology.
- By requiring manual bidding adjustments for every auction.
The correct answer is: By unlocking net-new searches using broad match and keywordless technology
Key Takeaways
- – AI Max for Search expands reach by unlocking net-new searches through broad match and keywordless technology, not by restricting match types.
- – It is a campaign or ad group level setting inside an existing Search campaign, so you do not need to build a new campaign type to test it.
- – Keywordless matching uses your landing pages, final URLs and creative assets as signals, which is why weak or thin landing pages hurt performance more than usual.
- – Wider matching means more irrelevant queries can slip through, so negative keyword lists, brand controls and locations of interest settings need to be reviewed regularly in the Search terms report.
What does keywordless technology actually mean in AI Max for Search?
It means Google can serve your Search ads on relevant queries even when no keyword in the ad group matches them. Instead of relying only on your keyword list, it reads your final URLs, landing page content and asset text to understand what you sell. This is the same underlying matching approach used in Performance Max, brought into a standard Search campaign.
Where do I turn on AI Max for Search in the Google Ads interface?
Open the Search campaign, go to Settings, and look for the AI Max section. You can enable it for the whole campaign or apply it to selected ad groups. Alongside the main toggle you will find the search term matching and asset optimisation controls, plus final URL expansion settings.
Does enabling AI Max mean my exact and phrase match keywords stop working?
No. Your existing keywords stay in the campaign and continue to drive matching. AI Max adds a layer on top so the campaign can also reach queries your keyword list does not cover. This is a common confusion, people assume it replaces keywords when it actually extends them.
How do I control irrelevant traffic after switching AI Max on?
Use campaign level and account level negative keyword lists, add brand exclusions if you do not want competitor or brand terms, and use the URL controls to stop Google sending traffic to pages you do not want promoted. Check the Search terms report weekly during the first month. Broader matching only works commercially when your conversion tracking is accurate, so verify that before you scale spend.
