What Changed in Google’s Mobile Organic Results in May?
Same search. Nearby location. Different organic results. Across 8.16 million location specific SERP snapshots, Yext found a sharp shift in mobile organic results beginning in mid May 2026.

Something changed in Google’s search results in May 2026.
Schieler De’Land first flagged it to Joy Hawkins after seeing people run the same search at the same time and get different organic results. Around the same time, similar reports started appearing in the Local Search Forum. Joy was seeing it too in Places Scout ranking grids, especially on searches where the city was already included in the keyword.
The question was whether this was just random ranking noise or something much bigger.
So Joy asked Mark Kabana at Yext to dig into the historical data.
What we found was not subtle.
The important change is not that rankings stopped mattering. It is that one observed ranking became a weaker description of an entire market. Clear winners still exist, but identifying them now requires looking at the pattern across many observations rather than treating one search as ground truth.
This study measures geographic variation, not conventional day to day ranking volatility. We compared the ordered top 10 organic results across nearby locations during the same report run.
The grid that made the pattern visible
Joy’s Places Scout grids gave us a concrete example to test. In an earlier scan, the tracked site’s organic ranking was relatively consistent across the market. By May 19, the same report looked far more scattered.
That May 19 scan was collected two days before Google’s May core update began. The timing made the pattern even more interesting, but one grid could not tell us whether Google had changed more broadly.
The two scans show what Joy saw. The analysis below tests whether that visual pattern held across the full dataset.

What changed in the frame. The May scan shows the tracked website appearing across a more scattered set of grid locations than the February scan.
For each keyword, we compared the ordered top 10 organic results between adjacent points on a search grid. A higher score means nearby locations received more different results.
The index sets each report and keyword’s earlier baseline to 100. A value of 125 means geographic volatility was 25% above that baseline.
We tested the pattern across 8.16 million SERP snapshots
Was this a handful of strange grids, or a broad change in Google’s mobile organic results?
The study covered 1,272 reports and 9,371 report runs. Each organic snapshot represented one keyword, one location, one run, and one device. Each snapshot contained up to 10 traditional organic results.
Organic, the classic 3 pack, and Maps were scored separately. Each report received equal weight after its query series were summarized, so large reports could not dominate the finding.
| Measure | Final count |

| Reports with usable output | 1,272 |
| Report runs | 9,371 |
| Organic keyword and run observations | 132,512 |
| Local keyword, run, and surface observations | 263,829 |

The break begins the week of May 18
From January through early May, the mobile organic index stayed within its normal range. It rose during the week of May 18, climbed again during the week of May 25, and stayed high through June and July.
That timing overlaps Google’s May core update, which began May 21. The study measures the overlap but does not prove the update caused the change.
The baseline equals 100. The mobile organic line moves above its earlier range in mid May, while searches that already named a location rise the most.
All three series moved above 100 after mid May. Explicit location queries reached the largest peaks, even though those queries already name a location.
Mobile organic breaks away after mid May. The classic 3 pack and Maps remain close to their historical baselines.
The median paired report change was 7.20 points. 702 of 718 reports increased and 16 decreased. The 95% interval for the median report change ran from 6.82 to 7.49 points.

The biggest surprise came from searches that already named a location. Their matched geographic-volatility score rose from 8.55 to 15.08.
The biggest surprise: searches that already named a location
High-confidence explicit location queries rose from 8.55 to 15.08, a 76.3% increase. Near me searches rose from 26.04 to 33.91, a 30.2% increase.
The two organic query groups show the widest gaps. Mobile classic 3 pack and Maps rise by less than one raw point.

| Mobile classic 3 pack | 23.28 | 23.84 |

The 3 pack and Maps did not follow
Mobile classic 3 pack volatility changed 2.4%, from 23.28 to 23.84. Mobile Maps changed 2.8%, from 18.16 to 18.66. Those shifts were tiny compared with mobile organic.
The change is concentrated in mobile organic. Explicit location queries rose 76.3%, mobile organic rose 48.7%, and near me rose 30.2%. The mobile local surfaces stayed below 3%.

The change did not fade after May
The longer January baseline shows normal earlier spikes, but no earlier period stayed as high as mobile organic did from late May through July.
The monthly view shows that the mobile organic increase lasted through June and July instead of fading after one volatile week.
Mobile organic holds above its earlier range in June and July. The other three series stay close to 100, apart from smaller desktop movement.
Early August was noisy, but it was not a second jump
From August 1 through August 9, mobile organic geographic volatility was 15.6% lower than the unusually high late July comparison. The 3 pack was 6.4% lower and Maps was 2.6% lower.
August still sat above the longer mobile organic baseline. It simply did not create another upward step in geographic volatility.
Mobile organic eased from 36.9 to 31.2. The classic 3 pack moved from 34.6 to 32.4, and Maps moved from 25.6 to 25.0.

| Mobile Maps | 25.6 | 25.0 |
One website’s rank became less consistent too
The share of pins matching the center rank fell from 38.9% to 31.5%. The share within one position of the center fell from 70.6% to 56.1%.
Both center agreement measures declined. More pins ended at ranks that differed from the center pin.
Same location comparison. Mobile organic ranking change at the same location rose 7.5% for runs separated by 3 to 10 days, far less than the 48.7% change across nearby locations.
Fewer pins matched the center after the shift, either exactly or within one position.
Mobile organic rose from 28.1 to 30.2. The classic 3 pack, Maps, and desktop organic declined in the same location group measured in both periods.

| Desktop organic | 24.2 | 23.2 |
Reports with the same result depth also became more volatile, so shorter result lists do not explain the change.
The result survived every major cross check
The finding remained when we compared domains, landing page URLs, center overlap, grid sizes, and reports with the same result depth before and after.
Nearby result sets were not only reordered. They also shared fewer domains, and the number of unique SERP variations increased.
| Supporting measure | Baseline | Later | Relative change |
|---|---|---|---|
| Neighbor URL volatility | 22.04 | 32.15 | +45.9% |
| Center domain volatility | 26.94 | 34.49 | +28.0% |
| Center URL volatility | 31.85 | 40.74 | +27.9% |
| Center domain Jaccard overlap | 64.03% | 55.23% | -13.8% |
| Unique ordered domain SERPs | 30.88 | 34.50 | +11.7% |
| Average organic result count | 9.35 | 9.06 | -3.0% |
Three volatility measures rise by 27.9% to 45.9%. Center domain overlap falls 13.8%, which points to fewer shared domains across nearby pins.
Grid-size sensitivity. The mobile organic increase appeared across 49-, 81-, and 121-location grids rather than depending on one layout.
The increase measured 29.0% for 49-location grids, 56.1% for 81-location grids, and 57.8% for 121-location grids.
It was not limited to one service category
Mobile organic volatility rose across all five broad service groups in the sensitivity check. The increases ranged from 21.2% to 70.6%.
These are broad groupings, not a formal industry model. Their purpose is to show that one category did not create the overall result.
The relative increase ranged from 21.2% to 70.6%. The share of reports that increased ranged from 95.2% to 100.0%.

A messy rank grid does not always mean the full SERP changed
The Toronto grid looks chaotic for one tracked website, but the full organic SERP changed only 8.6%. The Vaughan example shows a much larger full SERP change of 55.9%.
The heatmaps show one tracked website. The percentages below measure the full ordered organic SERP.
