Google rolled out a core algorithm update on May 21, 2026 that is the biggest shift in how local search works since the original Pigeon update over a decade ago. For Louisiana service businesses, the practical changes matter. Here is the plain-English version.
What changed
Google AI Overviews and AI Mode are now the default search experience for hundreds of millions of users, surpassing one billion monthly active users in the first year. Ads are now placed directly inside AI Overview responses. The classic ten blue links still exist, but they appear lower on the page, behind an AI-generated answer that often cites one to three businesses by name.
Why this matters for your business
The local pack (the three-business map result at the top of "near me" searches) used to be the prize. It still matters, but it is now competing with the AI Overview, which often features just one or two businesses instead of three. Industry data shows some businesses experiencing fifty percent or greater drops in visibility on local intent queries because they fell out of the AI Overview citation but kept their local pack position.
Ahrefs measured a 58 percent click-through rate drop on top-ranking content when an AI Overview is present. Fewer clicks, but those clicks convert at meaningfully higher rates. ChatGPT-referred visitors convert around 15.9 percent versus the typical 1.76 percent organic baseline.
What to do about it
The play is to be the business cited inside the AI Overview, not just the one ranked below it. Three concrete moves:
1. Add structured FAQ blocks to every service page on your site. Each FAQ should be one direct question and one direct answer in plain English. Mark them up with FAQPage schema. AI engines pull citation candidates from FAQ-formatted content first.
2. Build out your Google Business Profile Services entries with full descriptions. The Services entries feed AI Overviews directly. A Houma plumber with three Services entries gets cited less often than a Houma plumber with twelve.
3. Add llms.txt to your website. llms.txt is a simple text file in plain English that summarizes who you are and what services you offer, written for AI assistants to read. ChatGPT, Perplexity, and Google AI Mode are starting to use it when they pick businesses to recommend.
The May 2026 update is going to be the dividing line between Louisiana service businesses that get cited by AI search and Louisiana service businesses that disappear from the customer's search. The good news: the bar is still low. Most local competitors are not optimizing for any of this yet.
