Anyone who has searched for anything in the past few months has seen the block: a summarising answer at the top of the page, before the first blue result. That block is called an AI Overview, and it quietly changes what a search result is.

01 / the blockWhat the visitor sees

An AI Overview is a summary that a language model compiles from multiple pages, with references to those sources next to or below the text. So the visitor gets to read the answer before clicking a single result.

The block doesn't appear for every search. Google mostly shows it for questions suited to a summarising answer: explanations, comparisons, how-does-this-work questions. If someone searches for a specific company by name, the block usually stays away. The most-cited industry measurements put the figure at around 45 per cent of searches where such a block now appears.

02 / the selectionHow Google chooses its sources

Google chooses its sources close to the regular rankings. The company itself says that the AI features are rooted in its existing ranking and quality systems. Anyone who doesn't rank anywhere rarely appears in the block. Anyone who scores well on the underlying questions stands the best chance of being cited as a source.

That's a significant difference from ChatGPT and Perplexity, which look further than the top results and regularly cite pages that aren't at the top. For a complete picture of what visibility in AI systems involves, what is AI visibility is the starting point.

03 / the click-throughsWhat it does to your visitors

Some of your visitors stay in the block. Measurements show up to 58 per cent fewer click-throughs when an AI Overview appears above the results. That's not a fringe effect but a shift in how search works.

Anyone who already has the answer stops clicking.

There's something on the other side of the ledger. The visitor who does click through after reading the block arrives more targeted than the visitor of old, and the company that appears as a source in the block is seen by everyone who reads the summary. For the site owner, the balance can be summarised as follows.

The table isn't an argument for or against: the loss of clicks and the gain in visibility are two sides of the same block. Which side weighs more heavily for you depends on how many of your customers arrive through search queries where such a block appears. What this shift means for your visitor numbers, and what to measure and let go of, is covered in are you losing visitors to AI answers.

04 / the positionWhat Google itself says about it

Google is notably matter-of-fact about what you should do: nothing special. No special markup and no separate AI file are required to appear in AI Overviews. The advice is the same as for the regular search results: write for people, actually answer the question, and keep your site technically sound.

Google even warns against the opposite: chopping content into small pieces because AI would understand it better, or writing separate texts for AI systems. Google says the former is unnecessary, and the latter can be flagged as spam. Anyone who builds their pages with normal headings, clear paragraphs and an answer up front does well by both worlds.

In practice that means the work you do for your regular visibility is at the same time your work for AI Overviews. No separate track is needed, and no second site either. It does pay off to know whether the block appears for your search queries and who's in it, because that varies a great deal by topic. That check takes an afternoon and determines whether this is urgent for you or a side issue.

05 / the limitWhen this isn't your priority

Three situations in which AI Overviews belong low on your list.

Your customers don't arrive through search. If your business runs on referrals, a fixed circle or one large contract, an answer block on Google changes little about that.

Your basics aren't in place yet. A site that loads slowly, isn't indexed or doesn't answer customers' questions has more to gain from the basics than from the block. The rankings are the gateway, and you earn those with the regular work.

You're looking for a quick fix. That doesn't exist here. Visibility in AI Overviews follows from positions you build up over months, not from a setting you switch on.
