What's the practical difference between an AI summary above search results and a full AI search mode?
A summary sits above the conventional results and answers one query with a few links; the normal result set is still there and still earns clicks. A dedicated AI mode replaces the results page with a conversation, fans one question into several underlying searches, and carries context between turns. The second changes which pages get seen far more, because you are competing for passages across several rewritten queries at once.
One query versus a fan-out
A summary answers the query as typed. A conversational mode decomposes it. Ask which air conditioner to buy for a house in a hot climate and the system may run separate searches for sizing, efficiency ratings, common failure modes and installation considerations, then assemble one answer from several source sets.
That decomposition is the important part. You are no longer competing for a keyword. You are competing for the sub-questions the system generated, most of which you never chose and cannot see.
Coverage matters more than any single page
A homeowner whose system stopped cooling moves through a predictable ladder: what is wrong, is it urgent, can I do anything myself, what does a repair involve, repair or replace, what drives the price, how do I choose a company, who near me does this well.
A site that covers the bottom rung only — the service page — enters the conversation late, if at all. A site that covers the ladder appears in several turns, and the last turn is where a company gets named. That is the argument for a structured answer library over a handful of service pages.
Local questions play by different rules
When the question turns to who nearby can do the job, the answer leans heavily on map and listing data rather than on your prose: category, service area, hours, reviews, verification status. Excellent explanatory content does not compensate for a wrong category or an unverified profile.
So the two halves of the work are genuinely different. Content wins the explanatory turns; records and listings win the selection turn. Doing one without the other leaves you in the conversation but not in the recommendation.
How to prepare without guessing at product roadmaps
You do not need to know which interface a person used. Both reward the same things: content that answers a specific question in a self-contained passage, technical accessibility, and consistent third-party records.
The difference is emphasis. In a fan-out world, breadth across the buyer's sequence pays more than depth on one page. Start by writing down the ten questions your phone staff answer most often — those are the rungs, in the customer's own words, and they are already recorded in your call data.

Have a version of this question about your own business?
The useful answer usually depends on which systems you run and how they're connected. That's a conversation, not a blog post.
