Growth Intelligence Brief #21
Is Google splitting AI Overviews from SEO visibility?
Welcome to another Growth Intelligence Brief, where organic growth leaders discover what matters and guidance on how to stay ahead of the competition in under 5 minutes. Data window: SEO visibility and AI prompt counts June 1 to June 29, 2026 (28 days, matched windows).
Exec Summary
The 5 biggest companies by AI mentions all gained SEO visibility and lost AI Overview mentions in the same 4 weeks to June 29.
For 2 quarters, SEO trended down and AI up. No mas.
The 5 biggest companies by AI mentions all gained SEO visibility and lost AI Overview mentions in the same 4 weeks to June 29. Their AI Mode mentions went the other way and grew.
LinkedIn gained 43.3% in visibility over the 4 weeks to June 29 (289.4 to 414.7), while AI mentions held flat at -2.0%. The gain is all organic, and it still leaves LinkedIn 9.1% below its April 2024 peak of 456.3.
Barnes & Noble lost 55.4% of its visibility in 4 weeks (24.76 to 11.04), the steepest drop of any tracked company with a real base.
AI mentions across the index have been flat for 8 weeks near 6.0 million per week. That flat number hides a rotation between AI surfaces that reverses how the divergence reads.
Home improvement bucked the flatline with 25% to 50% AI-mention growth in 4 weeks, while the same cluster’s organic visibility stayed flat. Summer project demand is showing up inside AI shopping answers now, not in 2027.
Let’s dig in.
SEO landscape check
Below is a quick read on the current state of search, built from the SSI (Search Signals Index): roughly 2,600 companies tracked across 26 verticals on 2 dimensions, SEO visibility and AI mentions.
The biggest platforms got their visibility back. Reddit, Facebook, Instagram, LinkedIn, and YouTube each gained between 11% and 43% in SEO visibility over the 4 weeks to June 29, and and each lost AI Overview mentions over the same period. GIB 20 flagged Reddit declining on both dimensions for the first time. Half of that fall reversed inside 3 weeks.
Google’s May core update finished rolling out on June 2, and the volatility ran through mid-June (Search Engine Land), reshuffling organic shelf space back toward the largest platforms while AI Overviews moved the other way.
The platforms clawed back their visibility
Social Networks gained 21.1% in visibility as a vertical over the 4 weeks to June 29, the third-strongest move in the index. And quite coincidental with Google’s announcement of organic social visibility tracking in Google Search Console. The recovery concentrates on the names that got hit in GIB 17 and GIB 20.
Reddit is the clearest case.
Its visibility bottomed at 2,297.6 on June 8, climbed to 3,041.2 by June 22, then settled at 2,765.7, up 18.1% on the 4-week window.
GIB 20 measured Reddit down 11.7% through June 8. The decline reversed inside 3 weeks.
The rest of the vertical moved in lockstep.
Facebook gained 20.1% in visibility
Instagram gained 21.4%
LinkedIn gained 43.3%
X gained 38.6%
All of this occurred over the 4 weeks, ending June 29. The jump clustered in the June 15 to June 22 window for every one of them, which is the fingerprint of an algorithm change rather than organic demand.
But their AI Overview mentions went the opposite way:
Reddit lost 12.8%
Facebook dropped 12.1%
TikTok lost 12.1%
Instagram decreased 9.7%
The platforms Google just rewarded in organic are the same ones AI Overviews cited less often in June. That split is the story of the month. SEO visibility and AI citation used to drift together for the mega-platforms. In June, they came apart.
Movers & Shakers
Top 5 Movers (4-week SEO)
Yellow Pages (Local Search) +66.3%. Vis 14.52 to 24.13, an all-time index high. 2nd consecutive issue on this list after +137.2% in GIB 20‘s window. AI mentions stayed flat at +0.8%, so Google routing is doing all the work.
Trustpilot (Ecommerce) +54.3%. Vis 63.51 to 97.96, also an all-time index high, adding 34.5 raw visibility points. GIB 20 asked whether the local routing favors Yelp specifically or review aggregators broadly. Trustpilot answers that: broadly.
Ace Hardware (Ecommerce) +43.9%. Vis 9.66 to 13.90, with AI mentions up 45.8% over the same window. Both dimensions point the same way, and it sits inside the home-improvement cluster below.
LinkedIn (Social Networks) +43.3%. Vis 289.43 to 414.74, adding 125.3 raw visibility points. Full breakdown in the Winner callout below.
Bed Bath & Beyond (Ecommerce) +41.6%. Vis 13.44 to 19.03, with AI mentions up 23.3% in the same window. Ecommerce as a vertical gained 4.3% in 4 weeks, so this is domain-specific.
Top 5 Shakers (4-week SEO)
Barnes & Noble (Ecommerce) -55.4%. Vis 24.76 to 11.04. 2nd consecutive issue on this list after -32.0% in GIB 20‘s window. Full breakdown in the Loser callout below.
Alibaba (Ecommerce) -40.6%. Vis 7.05 to 4.18. AI mentions stayed flat at +0.9%, so nothing is absorbing the loss.
Shutterfly (Images) -34.4%. Vis 6.90 to 4.53. A full round trip: GIB 20 ran Shutterfly as its #2 mover at +88.9%, and it now sits back below the 5.98 where the April slide began.
Angi (Local Search) -29.5%. Vis 4.84 to 3.41 while AI mentions grew 78.9%, the sharpest split in the index. Angi has moved against its own vertical for 2 straight issues, and Local Search gained 22.8% in 4 weeks.
VRBO (Travel) -25.8%. Vis 6.92 to 5.13, with Airbnb down 23.9% over the same 4 weeks. The vacation rental squeeze GIB 20 flagged has not let up.
Winner: LinkedIn
LinkedIn gained 43.3% in visibility over the 4 weeks to June 29, from 289.4 to 414.7. It climbed every week after June 8: 280.7, then 335.7, then 398.4, then 414.7.
AI mentions held roughly flat at -2.0% over the same window, so the gain is all organic. LinkedIn still sits 9.1% below its April 2024 peak of 456.3, which makes this a recovery rather than a breakout. Its user-generated pages are exactly the large-platform real estate the June reshuffle favored.
Loser: Barnes & Noble
Barnes & Noble lost 55.4% of its visibility over the 4 weeks to June 29, from 24.76 to 11.04, the steepest drop of any tracked company with a real base.
Mid-tier retail took the other side of the platform trade: As Google handed shelf space to the largest sites, names like Barnes & Noble, Kohl’s (-20.1% in 4 weeks), and JCPenney (-15.2% in 4 weeks) gave it up. Macy’s, the surprise winner from GIB 16, slid another 11.9% in June after the bulk of its round trip landed in GIB 20.
The flat AI line hides a surface rotation
AI mentions across the index have been flat for 8 weeks. The summed total for AI Overviews and AI Mode has held in a band around 6.0 million per week since late April, with June 29 at 5.96 million. The explosive growth that defined GIB 15 through GIB 17 stopped at the aggregate level.
That flat line is 3 trends stacked on top of each other. Over the 4 weeks to June 29:
AI Overviews fell 3.2%, from 5.47 million to 5.29 million
AI Mode grew 22.5%, from 547,193 to 670,163
ChatGPT mentions fell 28.4%, from 1.20 million to 860,743
AI Overviews carries roughly 8x the volume of AI Mode, so the sum barely moves while the mix underneath rotates.
The platform decline is mostly AI Overviews. Total AI Overview mentions fell only 3.2% while the 5 biggest platforms fell 10% to 17%, so the platforms lost share within the surface.
Commercial sources took it: Yelp’s AI Overview mentions grew 14.9%, Home Depot’s 21.5%, and Ace Hardware’s 35.1% over the same 4 weeks. AI Mode coverage held steady near 342 tracked companies all month, so the AI Mode growth reflects Google citing more sources rather than the index tracking more companies.
The signature divergence trade went quiet with it. Screening for companies with at least 2,000 AI mentions at baseline, AI mentions up more than 10%, and visibility down more than 5% over the 4 weeks to June 29 returns 5 names:
Zapier
Office Depot
GetYourGuide
Nordstrom
Hilton
All sit on small bases. Angi runs a sharper split than any of them and falls just under that mention floor.
Keep in mind what flat means here: AI engines still mention these 2,600 companies about 6 million times a week. The growth curve bent, but the level held.
Home improvement is where AI demand is still rising
One cluster bucked the plateau. Home-improvement and big-box retail posted 25% to 50% AI-mention growth over the 4 weeks to June 29:
Wayfair +48.1%
Ace Hardware +45.8%
Lowe’s +32.8%
Home Depot +30.9%
Best Buy +28.8%
Michaels +29.2%
Ecommerce was the second-fastest vertical for AI mentions at +10.9% over the same window.
Organic search never moved. The same cluster’s combined visibility fell 0.7% over the identical 4 weeks, and June has been flat for these companies every year the index has tracked them: 0.0% in 2023, -2.8% in 2024, and +0.9% in 2025. Seasonal project demand is real, and it only shows up in AI surfaces.
The caveat sits in the data window: AI mention tracking began in February 2026, so June 2027 is the first chance to confirm the pattern repeats. If it does, AI surfaces reprice seasonal commercial intent faster than the organic index does, and AI shopping answers become a seasonal channel a growth team can plan against.
