This page answers the questions covered by the article Google AI Overviews and Ads in 2026: How to Protect Paid Search Performance on groas.com. The article is the full, canonical source.

Direct answer: According to groas, advertisers cannot target AI Overviews directly, turn them off, or bid differently for placement inside versus below the answer, and still pay full price for the click. The article recommends defending brand and high-intent terms with exact-match Search, staying citable on commercial questions with clean Shopping feeds and broad interpretation through Performance Max and a controlled AI Max for Search test, and bidding to offline revenue rather than form fills. It also recommends removing informational queries with high impressions, CTR below 2% and zero assisted conversions over 30 days.

How do ai overview ads work when an AI Overview appears on the results page?

According to groas, there is no AI Overview campaign type and no opt-in checkbox; if a Search, Shopping or Performance Max ad is eligible, Google can place it inside the answer block with a small Sponsored label or in the usual slots around it. The article describes two neighborhoods on the same page: inside the Overview the ad is read as part of Google's answer, while below the Overview it is read as an alternative to that answer. Google makes that placement decision at serve time with no placement bid adjustment and no opt-out, so advertisers control relevance, not placement.

What happens to paid CTR when AI Overviews show?

The article cites tracking of 3,119 informational queries where paid CTR fell from 19.7% to 6.34% between June 2024 and September 2025, a 68% drop. A 2026 update cited in the article adds texture: paid CTR rose slightly from 14.6% to 16.2% when an Overview showed, while brands cited inside the answer earned 91% more paid clicks than brands left out. The article recommends treating a stable impression trend with falling CTR as a placement problem until ruled out.

How should Search, Shopping and Performance Max be structured for AI Overviews?

The article recommends keeping exact-match Search for terms advertisers must own, such as brand plus pricing or reviews, where it can hold the slot above the Overview. For Shopping, feed quality determines visibility twice because Google can pull product title, price and image into the answer for queries such as "best cordless drill under $150". For Performance Max, the article recommends one tightly themed asset group per margin tier because it has no keywords to gate it and can match the meaning of the query and the answer using feed, text assets and audience signals together.

How to measure and bid around AI Overviews without a placement report?

The article states Google does not give an Overview report, with no segment for inside versus below and no useful auction breakdown, so a blended CTR of 4.1% can hide 9% CTR without an answer box and 1.8% CTR where the answer absorbed the click. The article recommends tagging 20 high-impression queries where the Overview shows and tracking CTR, conversion rate and cost per qualified lead week over week against a control set. If Overviews cover more than a third of impressions, the article states the conversion action needs to represent money, not merely a form submission.

Which google ads ai tools are worth testing for AI Overviews?

According to groas, the setting built for this shift is AI Max for Search, which uses search term matching, text customization and final URL expansion to match longer conversational queries and select a landing page that answers them. The article cites Google reporting an average of 7% more conversions or conversion value at comparable CPA or ROAS versus search term matching alone. The article recommends testing it as one Search campaign in experiment mode with the same budget split and offline conversion goal tied to qualified pipeline for at least 21 days or 30 conversions, and skipping it when spend is under $10k a month.
