Surviving Google's local algorithm updates: a UK guide
Every year Google shakes the map pack, and every year businesses that were "doing fine" disappear from searches they owned. Here's how local updates actually behave, how to tell an update from a problem you caused, and why boring white-hat signals are the only ranking that survives.
Twice or so a year, UK trade forums fill with the same post: "ranked top 3 for years, vanished overnight, changed nothing." Sometimes the poster did change something. Sometimes a competitor earned the spot. But sometimes it's the third thing: Google moved the goalposts for everyone at once.
In short
Google updates its local ranking systems regularly — some announced, many not. Most "I got hit by an update" cases are actually something else, so diagnose before you react: check for profile problems, competitor movement and measurement changes first. When it genuinely is an update, the recovery path is the same boring one that prevents the damage: fundamentals, not tricks.

Google publishes its update history for core updates, and its local ranking framework — relevance, distance, prominence — has been stable for years. What updates change is the weighting and policing inside that framework.
The pattern from past local shake-ups (the industry named them Possum, Hawk, Vicinity — Google mostly didn't) is consistent: each one re-balanced proximity, filtered near-duplicate businesses, or cracked down on a manipulation tactic that had started working too well. The lesson isn't in any single update; it's that the tactics updates punish are the same ones every time — stuffed business names, fake addresses, bought reviews.
First, prove it's actually an update
The overnight-drop post has four usual suspects, and the algorithm is the least common:
- Your profile changed state. A suspension, a rejected edit, or Google accepting a public "suggest an edit" to your category or hours. Check the profile dashboard before anything else.
- A competitor did real work. New reviews, a rebuilt profile, a second location. One business improving looks identical to you dropping — from where you're standing.
- Your measurement moved. Checking from a different device, logged-in state or location changes what you see. This is why a single search from your own kitchen is worthless as tracking — and why we scan a whole grid from fixed points every month.
- An actual update. Broad movement, same dates, across many of your tracked squares at once — and other businesses reporting the same window.
Only the fourth one is an algorithm story. A month-by-month geo-grid history makes the diagnosis in about ten seconds, which is most of the reason we insist on it.
The two-week rule
When it is an update: change nothing for two weeks. Rollouts take days and often partially rebound. The panic moves — swapping your primary category, rewriting your description, buying a burst of anything — destroy your ability to see what the update actually did, and they're exactly the erratic-behaviour pattern you don't want attached to your profile while Google is re-evaluating it.
After the dust settles, compare your grid before and after. Lost everywhere? Prominence issue — reviews, citations, links need a quarter of real work. Lost only at the edges of your patch? Proximity re-weighting — tighten focus on your core area and win it deeper. Lost for one keyword family? Relevance — your services and categories drifted from what you actually sell.
Building the ranking that survives
Every local update Google has shipped rewards the same dull portfolio: the right categories honestly chosen, real reviews arriving steadily and answered, consistent name-address-phone everywhere, an active profile with fresh photos and posts, and a real location serving a real area.
None of that is clever. That's the point — clever is what updates are built to catch. A business that ranks because of a keyword-stuffed name is renting its position from a loophole; a business that ranks on fundamentals owns it through every shake-up.
That's also the honest sales pitch for white-hat work, and the only guarantee we'll ever make about algorithm updates: we can't promise you'll never move, but we can make sure that when Google swings the bat, you're not one of the things it's aiming at.
Quick questions
How do I know if a local algorithm update happened? +
Check Google's published update history first — core updates are announced there. Local-only shake-ups often aren't announced, so the practical signal is a sudden, broad movement across your whole rank grid on the same dates other businesses report movement, not just one keyword twitching.
My rankings dropped overnight. Is it always an update? +
Usually not. The most common causes are closer to home: a profile suspension or pending edit, a category that got changed, a new competitor doing real work, or simply measuring from a different spot than before. Rule those out before reacting to a ghost.
Should I make big changes right after an update? +
No. Updates often roll out over days and partially rebalance afterwards. Panic edits in week one — swapping categories, rewriting everything — make it impossible to tell what actually worked and can hurt you when the dust settles. Diagnose first, act in week two or three.
Can an update be good for my business? +
Yes. Every shake-up demotes someone — often profiles propped up by spam. If your profile is clean and active, an update that clears keyword-stuffed names or fake-review competitors out of your pack is free ranking gain. That's the honest case for white-hat work: you're on the same side as the algorithm.
Does Google update local rankings more than normal search? +
The local pack has its own ranking system and it moves constantly in small ways — proximity alone re-sorts it per searcher. Named shake-ups are rarer, but because local results are so location-sensitive, even ordinary changes can feel dramatic in a dense area.
