Google's May 2026 core update did something we have not seen at this scale before. Reddit grew its top-3 presence in every single niche tracked across a 100,000-keyword analysis. Not most niches. All twenty. If your brand competes for informational or experience-led searches, a forum thread is now sitting in the spots you used to own, and it is happening across the board.
This is not a small wobble. According to SE Ranking's analysis of the May 2026 core update, Reddit's overall top-3 share climbed to 10.24% after May, up from 8.56% after March and 9.19% after December. That is roughly one in every ten top-3 positions going to a single platform. As I broke down in my LinkedIn post, the direction of travel matters as much as the numbers themselves.
Key Takeaways
- Reddit grew its top-3 share in all 20 niches tracked after the May 2026 core update, reaching 10.24% overall.
- Reddit held the #1 spot for 13,872 keywords after May, a 54% jump from 8,993 after March.
- The biggest gains landed in experience-led niches: Pets (+3.18pts), Education (+3.03pts), Sports and Exercise (+3.02pts), and E-Commerce and Retail (+2.61pts).
- YMYL niches like Healthcare and Real Estate barely moved, suggesting Google still trusts expert sources for high-stakes topics.
- The SERP was brutally volatile: 76.03% of top-3 URLs changed position, and only 32.20% of domains that lost top-10 rankings in March had recovered by May.
Reddit Did Not Just Grow. It Took Over the Top Spot
The headline figure is the niche-wide growth, but the sharper story is the #1 positions. Reddit held the top organic result for 13,872 keywords after May, up 54% from 8,993 after March. That is not Reddit creeping into position three. That is Reddit beating your homepage, your service page, and your blog to the single most valuable slot on the page.
The gains clustered exactly where you would expect people to crave real opinions over polished brand copy. Pets jumped from 14.87% to 18.05% (+3.18 points). Education rose from 10.46% to 13.49% (+3.03 points). Sports and Exercise went from 9.75% to 12.77% (+3.02 points). E-Commerce and Retail climbed from 11.50% to 14.11% (+2.61 points). These are searches where buyers want lived experience: which product actually lasted, which course was worth it, what worked for someone like them.
Where Reddit Did Not Win: YMYL Stayed Put
The flip side is just as telling. Your-Money-Your-Life niches barely budged. Healthcare moved from 0.93% to 1.33% (+0.40 points). Real Estate shifted a rounding error, from 3.67% to 3.73% (+0.06 points). News and Politics added 0.78 points. Google still appears to want vetted, accountable sources when the stakes are health, money, or property. If you operate in a YMYL space, this update is less of a threat and more of a reminder that demonstrable expertise is your moat. This is the same logic we unpacked when Google's March 2026 core update reshuffled the rankings.
A Full Reversal From March
What makes May fascinating is that it undid March. After the March core update, Amsive found that Reddit and similar user-generated sites lost US search visibility while brand sites gained ground. SE Ranking's own March data showed Reddit's top-3 share dipping below its December level. Then May swung the pendulum hard the other way. Two consecutive core updates, two opposite outcomes for the same kind of content. The lesson for anyone running SEO services in Singapore is simple: do not over-index on a single update. Build for durability, not for the last algorithm tweak.
YouTube Quietly Lost Organic Ground
While Reddit surged, YouTube's top-3 organic share slipped to 2.14% after May, down from 2.50% after March. The likely explanation is not that YouTube is losing relevance, but that its results are migrating into video SERP features that this organic-only analysis does not count. It is a useful reminder that the blue-link ten is no longer the whole battlefield.
The SERP Was Chaos, and Recovery Is Slow
Underneath the Reddit story sits real turbulence. SE Ranking found 76.03% of top-3 URLs changed position after May, and a staggering 88.39% of top-10 URLs moved. Around 19.87% of top-10 pages dropped clean out of the top 100. Recovery has been ugly too: only 32.20% of domains that lost top-10 rankings in March had returned by May, leaving 67.80% still waiting. And 17% of the current top-10 are brand-new entrants. Translation: rankings are not just shuffling, they are being rebuilt, and sites that get hit are not bouncing back quickly.
One Honest Caveat Before You Panic
Worth flagging for transparency: this data comes from SE Ranking, which sells rank-tracking and AI-visibility tools, so it has a commercial interest in the topic. The study tracks a single US location (New York) and counts organic blue links only, with no SERP features, AI Overviews, or video carousels. The patterns are clear and corroborated by Search Engine Journal's coverage, but Singapore SERPs and feature-rich results may behave differently. Treat it as a strong signal, not gospel.
What This Means for Your Brand
Reddit's rise and the parallel growth of AI-driven answers point the same way: people increasingly trust peer voices and synthesised answers over brand pages. That does not make your site irrelevant. It changes the job. You need content worth citing, a presence in the communities that now rank, and a strategy that spans both classic search and AI surfaces, the exact shift we covered in our piece on how AI is changing SEO. It also ties into the broader move toward conversational discovery we explored when Google began answering questions straight from Maps and Business Profiles.
The brands that win from here are the ones building genuine authority and getting found wherever the answer lives. That is precisely the work we do as a GEO agency in Singapore, pairing traditional rankings with visibility inside AI-generated results.
