Personalized Search Results: Why Your Google Rankings Look Different on Every Screen

Personalized search results are the first thing people blame when their own Google search disagrees with a ranking report, and they are only part of the story. Two people typing the same words into Google on the same afternoon can see different pages, because Google adjusts results to the searcher’s location, language, device and recent activity, and then to their search history if they are signed in. A fixed-location Google rank checker that queries from a set country and device removes the biggest of those variables, which is why its numbers rarely match your own screen.

That is why a client can call you to say “we’re number 2, your report says 6”, and both of you are telling the truth. Below I explain what changes a Google results page, what personalisation really does (and how to switch it off), and how a non-personalised check from a set country, city and device settles the argument.

Why two people get different results for the same search

Google publishes a short help page on why your Google Search results differ from others. It groups the reasons into three: time, context and personalisation. Here they are, with what each one does to a hand check.

What personalized search results are, and what they are not

Google’s page on personalisation and Google Search results describes it as Search showing you results based on information in your Google account, such as your search history, when a setting called Personalized Recommendations is on. Three points from that page matter for rank checking:

• Not every result is personalised. Personalisation can change the order of results, or the order of blocks on the page. Google’s own example: if you usually watch videos, it may put videos above websites.
• Switching it off does not make results neutral. With personalisation off, Google says it still uses your location, your language, the type of device you use and your current searches.
• The page tells you. When personalisation is off, or Google has too little information to use, the bottom of the results page says “Results are not personalized”.

To switch it off:

1. Signed in: turn off Personalized Recommendations in your Google account’s search personalisation settings.
2. Signed out: turn off the setting Google calls Search customization.
3. For one search only: use the “Try without” link at the bottom of the results page. Your settings don’t change.

So a signed-in business owner who searches for their own business often may see a different order from a stranger. But turning personalisation off rarely closes the gap on its own, because location, device and time are still in play.

Location: the input you can’t see on the screen

Google’s help page on how it determines your location when you search lists four sources:

• Your device’s location, if you allow google.com to use it. This can be precise.
• Your home and work addresses in your Google account, used when it’s likely you are at one of them.
• Your past activity, such as places you searched for before.
• Your internet address (IP), which Google describes as roughly based on geography.

Google always estimates at least a general area: larger than 3 square kilometres and with at least 1,000 users. The same page notes that when a browser is slow to share its current location, google.com may reuse the device location from your last search, kept for up to 6 hours.

An illustration, not real data: a dental clinic owner searches “emergency dentist” on a phone at the practice; their agency searches the same words on a laptop across town. Google is answering two different questions, and neither answer is “the ranking”.

Device and timing: the two things people forget to match

Google tailors results to the device, so a site can sit at different positions on a phone and on a computer. In our public sample report, “hotel pms system” ranked 8th on Google.co.uk desktop and outside the top 30 on Google.co.uk mobile, in the same check. If the client searched on a phone and the report row was desktop, both would be right.

Timing is the other one. Google says time may be one of the biggest reasons results vary between people, and that ranking improvements take time to roll out across its data centres. A position checked on Monday morning is not a check of Thursday afternoon. Small differences between two checks a few hours apart are normal, which is why one screenshot proves very little.

Personalized search results vs a non-personalised rank check

A rank check removes the inputs you can’t control and fixes the ones you can. Our pay-per-check rank reports use a live check through a Google results API: one query per keyword per engine, with desktop and mobile as separate queries. An engine is one Google edition in one location on one device, for example Google.co.uk for the United Kingdom on mobile. No Google account or search history sits behind the query, and a city engine is checked from a point inside that city, not from a national average.

That does not produce “the one true ranking”. It produces a position you can repeat: the same keyword on the same engine next month, measured the same way.

Figure 2 shows why this matters. In the public sample report, “hotel guest messaging” ranked 7th on UK desktop, 9th on UK mobile, 17th on US desktop and 14th on US mobile. None of those rows is personalised, and they still differ by up to ten places. Someone in the UK searching on a phone should compare their result with the 9, not with the 7 or the 17, and even then their own location within the country can move it.

A ranking without a country, a device and a date is an anecdote, not a measurement.

Why “your report is wrong” arguments happen

In my experience, the argument almost always comes from comparing two different things:

• Signed in, with history. The client is logged in to Google and visits their own site every day.
• Wrong device. The client checked on a phone; the row they are reading is desktop.
• Wrong place. The client searched from home in another city, while the report row is national or for a different city.
• Wrong day. The report ran on the 12th; the client searched on the 20th.
• Different wording. Singular and plural are separate keywords. In the sample, “pms for small hotel” ranked 28th on UK desktop and “pms for small hotels” 29th.
• Counting ads. The report counts organic results, so paid ads at the top of the page are not part of the count.

How to do a fairer hand check

You can get close to a report row by hand, as long as you control what you can:

1. Open a private window so you start signed out, or use “Try without” if you stay signed in.
2. Use the device the row is for: your phone for mobile rows, a computer for desktop rows.
3. Search from the place the row is for. If the row is for another country or city, a check from your desk will not match it.
4. Type the keyword exactly as it appears in the report.
5. Count organic results from the top, skipping ads.
6. Write down the date, the time and the position.

Even then, expect small gaps, because time and data centres still differ. Judge a report by the direction of its keywords over several checks, not by one position on one afternoon. Our guide to checking keyword rankings accurately compares the hand check with Search Console, subscriptions and one-off reports, and the walkthrough on how to read a rank tracking report shows what to do with the rows once you trust them.

If you would rather have someone read the report and turn it into actions every month, our SEO rank tracking service does exactly that. If you just need numbers you can defend in a meeting, you can order a non-personalised Google rank check for up to 400 keywords.

FAQ

Does incognito mode show non-personalised Google results?

Partly. A private window starts without your Google sign-in, so your account’s search history is not used. Google still uses your location, language, device type and current searches, so the page is not a neutral view. Treat it as one person’s search, from one place, at one moment.

Why are my Google rankings different on my phone and my computer?

Google tailors results to the device you use, so desktop and mobile pages can differ in order and in the blocks they show. A site can rank on one and not the other: in our sample report, one keyword ranked 8th on desktop and outside the top 30 on mobile. Always compare a phone search with the mobile row.

How accurate are rank trackers?

A rank check is accurate for the engine, location, device and moment it ran. It cannot match every person’s screen, because each search has its own location, device, timing and history. Compare direction over several checks rather than single positions.

Can I turn off personalized search results completely?

You can switch off Personalized Recommendations when signed in, or Search customization when signed out. Google notes that this does not pause or delete your stored activity, and that location, language and device are still used. So you can remove personalisation, but not context.

Why does my client see a different position from my report?

Usually because their search ran on a different engine: another device, another place, another day, or a signed-in account. Ask which device they used and where they were, then compare their result with that row. If no row matches their situation, add their city as an extra engine on the next check.
