Why does my Google ranking change depending on where I search from?
Short answer
For local searches Google works out the results separately for each searcher's location. Distance from the searcher is one of the three things Google says it ranks local results on, so the same search gives different results at your office, at home and across town. There's no single ranking to check.
Your Google ranking changes with where you search from because, for local searches, Google works out the results separately for each searcher’s location. Google names distance as one of the three things local results are based on, along with relevance and prominence. Two people typing the same words a few neighborhoods apart are, in effect, asking different questions. So a business doesn’t have one ranking. It has a ranking at every place a customer might be standing.
Where Google thinks you are
Google places you using the device’s location if you have allowed it, and otherwise from rougher clues such as your internet connection. That’s why the phone in your truck and the desktop in your office can disagree. The phone knows roughly which street it’s on. The desktop may only be placed in the right part of the county. Google usually shows the location it’s using at the bottom of the search results page, which is worth a look the next time a result surprises you.
What happens when the search names a city
Google measures from the place named. Someone in Oceanside who types “plumber La Mesa” gets results built around La Mesa. This is documented in general terms: Google says distance is calculated from the location term used in a search, and from what it knows of the searcher’s location when no place is named. It doesn’t say which point inside a named city it measures from.
A “near me” search works the other way. The words name no place, so the searcher’s own position does all the work, and that is the starting point for how to rank for near me searches.
Other reasons two people see different results
Location is the main cause, but not the only one. These also change what appears, and most are observation and not something Google documents in detail:
| Cause | What changes |
|---|---|
| The exact wording | “AC repair” and “air conditioning service” can return different businesses. |
| Time of day | Businesses that are closed at that moment tend to appear lower. |
| Search or Maps | The Google Maps app and the map pack on a search page don’t always show the same order. |
| Signed-in activity | Google says results can be personalized by past activity. How much this affects local results is unclear. |
| Layout tests | Google regularly tries different layouts, including where sponsored listings sit. |
Why checking your own ranking misleads you
Searching for yourself from your own office shows you the best case. You’re standing at the one point where distance favors you most. An owner in Carlsbad who sees first place every morning can be absent for a customer in San Marcos and never know it.
The same caution applies to any report that gives one position per search term. “You rank second for plumber” is only true somewhere. The question to ask is where the search was run from, and whether that is where your customers are.
How to see the real picture
Check from many places at once. A rank grid runs the same search from points spread across your service area and maps the result, so you can see where you’re strong, where you fade and where you’re missing.
If you want a rough check without one, ask a few customers or friends in other cities to search for your service and tell you what they see. It’s slow and patchy, but it’s more honest than searching from your desk.
I use grids as the before-and-after measurement for every change, and running them is the job of local rank tracking. Once you can see the pattern, the next thing to ask is how far from your office you can rank.
