The Google Diversity Update: Why Your Google Listing Might Be Costing You a #1 Ranking

What the Google diversity update actually does

There’s a naming problem here, and it’s worth sorting out first, because if you search the term you’ll get two different answers.

The original site diversity update was announced in June 2019. Google’s wording: “This site diversity change means that you usually won’t see more than two listings from the same site in our top results.” One domain, two organic spots. Old news, and not what’s hurting local businesses now.

The change causing trouble today was never announced, and it works differently. It doesn’t cap how many of your pages appear. It appears to decide whether a page shows up organically at all, once that same page is already sitting in the local pack for the query. Joy Hawkins at Sterling Sky named the pattern. Her read on Google’s logic is that if they’ve already shown a searcher a business in the local pack, they’d rather not show that business again in the organic results.

The part that makes it so easy to miss is that it hits at the page level, not the site level. Your domain is fine. Your other pages are fine. The page that gets pushed down is the one your Google Business Profile links to, which is the same page Google is already showing in the map pack.

For most single-location businesses, that page is the homepage. It’s usually the strongest page on the site and it’s carrying your most valuable rankings. So you lose your best organic position, everything else looks healthy, and nobody connects the two.

The test that exposed it

Sterling Sky ran the cleanest test I’ve seen on this, using live client accounts. They took a business and repointed its Google Business Profile at the page ranking number one organically for its main keyword. The page dropped to around tenth. They changed the profile URL back, and the number one ranking returned.

That’s what makes it worth paying attention to. Nobody was squinting at a rank-tracking chart and spotting a correlation. Change, drop, revert, recover, with the profile URL as the only thing that moved. In one home services case they tracked a single location losing 242 clicks while it was happening.

Barry Schwartz wrote it up on Search Engine Roundtable in February 2025. Colan Nielsen at Sterling Sky traced the behavior back to roughly August 2024, though some accounts weren’t affected until October or November. Which means a lot of businesses took an unexplained ranking hit that fall and never found out why.

Two things to be straight about. Google has never confirmed any of this. And when Schwartz tried reproducing it on his own listings, it didn’t fire every time. So treat it as a pattern that’s been replicated a lot, not a rule.

Why it’s believable anyway

Google has done this before, out in the open. In January 2020 Danny Sullivan confirmed what became known as featured snippet deduplication. If your URL shows as the featured snippet, its regular listing comes off page one. It usually turns up again around position 11. Win the snippet, lose the blue link.

The stated reason was decluttering. Ten distinct results on page one instead of nine plus a repeat. Apply the same thinking to the map pack, where your listing already takes up a big block near the top, and demoting the organic result stops sounding like a conspiracy theory and starts sounding like a product decision.

What this looks like for a small business

Say you run a two-truck handyman operation. Your homepage targets “handyman” plus your city, and it’s been working. Map pack most days, number one organic right underneath. Your Google Business Profile points at the homepage, because that’s what every local SEO checklist tells you to do.

Come October the phone is quieter. The map pack looks the same. The homepage is still on page one, so nothing looks broken. But you’re at nine instead of one, and in Search Console the clicks on that page have halved while impressions barely moved. That’s what a position change looks like, as opposed to demand drying up. You had two slots on that page. Now you have one.

What local pack dominance actually looks like

Be careful about what this does and doesn’t prove. A geogrid only measures local pack position. It says nothing about organic results, so on its own it isn’t evidence of the diversity update. What it shows is the situation that puts a business at risk. If you’re holding the top map pack spot across a whole metro, you’re exactly the sort of business the demotion is supposed to affect. Google already has your listing on the page, in a big block, before the first organic result loads.

So what happened to that business’s organic rankings?

Sometimes nothing happens at all

Here’s a case from our own client work that complicates the picture, and it’s worth walking through slowly, because the numbers only mean something once you know what they’re counting.

We track a single-location health and wellness clinic across about a hundred search terms, and we check every one of them in four separate places. Google can show a business as a regular blue link on a computer, as a blue link on a phone, inside the map box at the top of the page, and in the longer list you reach by clicking through that map box. A hundred terms checked in four places comes to roughly four hundred individual slots, reviewed every week.

That’s the unit to keep in mind for what follows. When we say positions, we mean those slots, not the hundred terms.

Over a twelve-week stretch in 2025, well after the diversity update had rolled out, this clinic held the top organic result and the top map pack spot at the same time across a large share of its terms, on desktop and mobile both. Two appearances on the same page, for the same search, over and over.

Three other things moved in that period, and each one means something different.

The clinic stopped being invisible. At the start, roughly one in seven of those four hundred slots came back empty. Not ranked badly. Empty. Somebody searching that phrase would not have found the clinic at all. Twelve weeks later that was down to about one in forty, a drop of more than 80%. This is the number I’d point to first, because it isn’t about climbing the page. It’s about being on it.

Average position improved by more than four places. Take every tracked slot, look at what number the clinic ranked at, and average them. That average moved up by more than four positions and finished inside the top five. Worth being straight about what drives a figure like that: some of the gain came from terms that previously showed nothing starting to appear at all, which pulls an average up quickly. It isn’t all fifth places turning into first places.

It finished appearing in more than 95% of the local packs available to it. Not every search produces a map box. Some just return blue links. That figure counts only the searches where a map box appeared, and it says that when Google decided to show one, this clinic was almost always inside it. There isn’t much room left to win on that surface.

None of that came from one clever fix. It came from rebuilding how the profile described the clinic’s services so it matched the way patients actually search, a steady stream of new reviews rather than one burst, and months of correcting and building business listings across the web. [Link: the work behind it.]

Which brings us back to the diversity update. This clinic is holding both slots, on both devices, well into the period when the demotion was supposedly active. So it doesn’t fire everywhere. If it were a hard rule, that account couldn’t look the way it does.

There might be an explanation sitting in the same data. Competing clinics barely show up. For most of those terms, rivals appear here and there or not at all. If Google doesn’t have a credible alternative to put on the page, maybe there’s nothing to swap in, so it shows the same business twice.

That’s a hypothesis, not a finding. I’d want to see it hold across more accounts before calling it a rule. But if it’s right, it points somewhere counterintuitive: the businesses most at risk from the diversity update are the ones in competitive markets with plenty of substitutes, not the ones in quiet corners.

Before you assume you’ve been hit, check. You’re only a real candidate if all three of these are true. You show in the local pack for a keyword that matters to you. You also rank in the top few organic spots for that same keyword. And the page your Google Business Profile links to is that top-ranking page.

There’s an irony in who got hurt. Multi-location businesses were mostly protected by accident, because their profiles were already pointing at location pages rather than the homepage. Single-location businesses took it.

How to check your own site in about twenty minutes

Pick three or four keywords that actually bring in calls. Search each one from the city you serve, not from your office in a browser you’re logged into, since that skews what you see. Note whether you’re in the local pack and where the site sits organically.

Then go to Google Search Console, open the Pages report, and filter to the URL your Google Business Profile links to. Pull average position and clicks for the last twelve months. You’re looking for one particular shape: impressions roughly flat, average position sliding from low single digits into the high single digits or the teens, clicks falling off hard. If that break lines up with the back half of 2024, or with a date you changed the profile URL, you’ve got a strong suspect.

Cross-check the profile’s own performance data while you’re there. If website clicks on the profile are steady while organic clicks fall, the local side is fine and the damage is happening organically.

Which page should your Google Business Profile link to?

This is where the standard advice has flipped, and it pays to be careful, because the obvious fix costs you something.

The old rule was to link the homepage, since it usually has the most authority and the most links pointing at it. The new version is narrower. Link to a page that’s clearly relevant to what the listing is about, but not your best organic page for your main keyword.

Here’s the catch. Sterling Sky’s earlier testing on this same question found that the content of the page you link to affects local pack relevance. In their law firm tests, pointing underperforming listings at tightly matched service pages improved local pack rankings for those terms inside a couple of weeks. So the page isn’t a neutral choice. Swap your homepage for something thin or generic or off-topic and you might save an organic position while damaging the local pack ranking that was generating your calls in the first place.

You want a real page. A main service page, or a city page with actual content on it, internally linked, somewhere a customer would be happy to land. Skip contact pages. Skip thin pages built purely to soak up the link. Skip URLs with tracking parameters stuck on the end.

And treat it as a test, not a decision. Change one thing, leave everything else alone, give it two to four weeks. Watch organic position for the old page, local pack position for the keyword, and clicks on both. If the trade goes badly, put it back. The reversal test suggests this is recoverable, which is more than you can say for most ranking problems.

The bottom line

The local results page keeps getting more crowded. AI answers are absorbing clicks on the informational side, and paid placement has been spreading inside the map pack. There are fewer free slots than there used to be. Which makes giving up a number one organic position you already earned, over a setting that takes thirty seconds to change, an expensive thing to leave unexamined.

Google has never acknowledged the diversity update. It doesn’t hit every business, and we have an account of our own that proves as much. But it’s been replicated enough times, with clean enough reversals, that it belongs on your list of things to check. If your organic rankings slipped since the middle of 2024 and you can’t explain why, and your Google Business Profile points at the page that slipped, you’re one controlled test away from finding out whether you’ve been competing against yourself.
