Google Local Algorithm Updates: The 2026 Local Search Change Log
Google changes how local search works constantly, and most business owners only find out when their calls dry up. This is the running log we keep for our clients: the updates that actually moved local rankings, in plain English, with what each one means for you.
New research: how AI decides which local businesses to recommend
Four September 2026 studies show AI systems recommend a local business when they can verify who it is, where it works, and which customer situations it serves, and that AI agents search through narrow follow-up queries, not the broad phrase a customer typed.
What new retrieval research means for semantic SEO
Retrieval studies suggest semantic SEO is not about adding related words, it is about answering the specific questions AI generates, keeping facts current, completing the evidence chain, and citing sources that actually prove each claim.
The “Dynamic SERP” volatility spike
Google’s May 2026 core update made local search far more volatile. Analysis of 8.16 million results found organic rankings became ~48.7% more volatile from the week of May 18, hitting mobile and geomodifier keywords (searches that include a city name) hardest.
March 2026 Core Update pushes AI Overviews into local
Google's March 2026 core update pushed AI Overviews deeper into local results, and industry tracking now puts roughly 46% of all searches as carrying local intent.
Discover Core Update rewards hyper-local expertise
The February 2026 Discover core update shifted the Discover feed toward hyper-local, in-depth expertise rather than broad, generic content.
'Ask Maps' replaces the manual Q&A
Google began retiring the old 'ask a question' feature in favour of 'Ask Maps', where Gemini scans your profile, website, and reviews to answer users conversationally.
AI place summaries reward fresh profiles
Google Maps now generates AI summaries from your reviews, posts, and web content, and multiple trackers report visibility drops when a profile sits 30+ days with no new photos or updates.
Video verification is the new default
Video verification is now the default for new listings in most regions, a single continuous take showing your signage, interior, and a live management action.
December 2025 Core Update leans on brand authority
Google's December 2025 core update leaned harder on real user engagement and brand authority for local queries.
Google removes the num=100 parameter
In September 2025 Google removed the num=100 parameter, so rank-tracking tools can now only read the first 10 positions instead of up to 100.
August 2025 Spam Update
Rolling out from August 26 to September 21, 2025, this update targeted spammy tactics across search.
Business Profile Q&A retirement begins
Late 2025 saw Google start phasing out the manual profile Q&A in favour of AI-generated answers.
The Vicinity Update (still matters)
Google's Vicinity update sharply reduced the ranking power of keyword-stuffed business names and put more weight on proximity to the searcher.
