Similarweb June 2026 Top 10: The Traffic Winners and Losers of the AI Era

If your organic numbers have gone soft and you're wondering where the visits went, Similarweb's ranking for June is a good place to look. It's the first month you can see the AI-era redistribution plainly at the very top of the global list.

ChatGPT now gets 5.6 billion visits a month, 24% more than last year, which puts it firmly in the global top five. Gemini has climbed to twelfth, growing 209% a year. Meanwhile, Wikipedia fell out of the top ten for the first time in a decade. CNN, Yahoo and Baidu, the publishers AI Overviews hurt most, each lost double digits in May alone.

All the figures come from Similarweb's live rankings and the blog analyses around them. If you run content for a SaaS company, the parts you'll want most are the three implications further down.

The June 2026 top 10

So who holds the top spots now? This is how Similarweb's live ranking of top websites looked in June:

Notice who's missing: Wikipedia, now at #11. It drew 3.5B monthly visits, 7.25% fewer than a year earlier. This is its first month outside the global top ten in roughly ten years.

If you're wondering where the AI platforms land, they start just below:

For the first time, the global top 25 includes four AI platforms, by the count in Similarweb's Gen AI Stats analysis. A year earlier there was one, ChatGPT.

Similarweb's official account posted about the June top ten as well:

The winners

Which sites are gaining? Sort them by growth and a pattern jumps out:

The first group is the AI platforms themselves, and ChatGPT is the story of the year. Count direct site visits and ignore search traffic, and it's larger at the top of the funnel than the rest of the top ten below it put together. So when you plan, count it among the five biggest destinations on the web. The index it retrieves from decides where 5.6 billion sessions a month end up getting answers.

Gemini grew faster than any other site in the top twenty. Google has been pushing it into Android, Chrome, Search and Workspace. In May it also made Gemini 3.5 Flash the default model for AI Mode. On that trajectory, you'll see Gemini in the global top ten by the end of the third quarter.

The second group is where AI engines send their citations, and Reddit is the clearest case you'll find. It's the most-cited source on every major engine, turning up in about 40% of AI citations according to 5W's Citation Source Index. That index covers 680M citations. The citation share is converting into visits on Reddit itself, which grew 21% year over year.

The third group rides algorithmic feeds. In June TikTok swapped places with Bing for tenth, the first time it has ranked above Bing. Its distribution algorithm helps, and so does the way younger users now treat it as their de facto search engine, with searches that start from discovery more than intent. Instagram grew its top-line visits, and on pageviews per session it now beats Facebook. On the measure that counts here, visits rather than registered users, that makes it the largest social platform globally.

Amazon is the odd one out. AI answers have eaten into the research-intent visits most retailers rely on, yet Amazon held steady and kept growing. When AI platforms retrieve product pages, they still send buyers to Amazon for the purchase, and individual retailer pages get passed over.

Lily Ray flagged the change in AI-platform traffic share back in May:

Wow - Gemini is still closing the gap.

If you only follow one race, make it ChatGPT against Gemini. ChatGPT still holds a 61% share of AI-platform visits, per Similarweb's first-quarter figures. Gemini, though, has narrowed the gap four quarters running. Even if Gemini grows at only half its 209% rate, their global visits land within 30% of each other by the first quarter of 2027.

The losers

If your plan depends on any of these sites, their numbers affect you too:

Wikipedia's drop has the widest consequences. It has been a global top-ten site for essentially all of Similarweb's measurable history. Its fall signals that ChatGPT, with its Wikipedia-heavy citations, is intercepting those visits at scale. Readers get Wikipedia's information inside ChatGPT and never reach Wikipedia. For the first time, AI diversion is visible in Wikipedia's metrics at the Foundation level.

You can't blame AI for much of WhatsApp's decline. What you're seeing there is competitive substitution: iMessage, Signal, Instagram DMs, and Telegram gaining in emerging markets. Still, landing in eighth instead of sixth or seventh reflects a messaging category that's fragmenting rather than consolidating.

If you rely on Bing, note that it's shrinking as a destination even with Copilot built in. Copilot itself is growing, eighth among AI chatbots. But bing.com keeps losing people to AI platforms they open directly, and Microsoft's search revenue takes the hit.

The regional search anchors, Yahoo.co.jp, Baidu and Yahoo.com, are all declining for the same reason. As ChatGPT and Gemini localize for 200+ countries (per Q1 earnings), the regional engines lose the captive audiences they relied on.

News is the category that got hit worst. Similarweb's blog tied CNN's May drop to AI Overviews absorbing publisher clicks. The Reuters Institute had already documented the global fall in publishers' Google traffic. What June shows you is that decline in the individual rankings, where news anchors that sat in the top 30 for years are dropping below the top 50.

What just happened on the ranking

What should you take from all this? A single quarter's rankings produced three shifts, and each one points you at a different decision.

If you've treated AI platforms as a niche, the scale numbers should change your mind:

At that size, a citation inside ChatGPT puts you in front of an audience on the same scale that algorithmic distribution on Instagram does. That's reason enough to treat AI platforms as a first-class distribution channel.

Look next at the platforms AI engines cite. Reddit is up 21% and YouTube is holding steady in second place. LinkedIn sits outside the top 20, yet Semrush's 89K-URL study shows it growing. The platforms AI engines quote most are the very ones whose traffic is speeding up. So your citation share on them becomes a distribution metric you track for its own sake, next to the AEO work on your own domain.

The third shift hits anyone whose PR plan still aims at Wikipedia and mainstream news. Wikipedia is 7% smaller than a year ago, and CNN lost 22% in a single month. The Yahoo variants are down 5% to 11% on the year. With declines that size, those outlets no longer earn their place as your main source of brand mentions. The weight has moved to Reddit, YouTube and LinkedIn, and to citations inside AI answers directly.

Practitioners on r/SEO reached the same conclusion:

Their shared view was that the "top websites" list changes quickly now. Similarweb's monthly refresh gives you the strongest signal for deciding which distribution channels still deserve investment.

AI platform placement detail

Where do the AI platforms rank against each other? In Similarweb's AI Chatbots and Tools vertical, ChatGPT is first and Gemini second, matching their fifth and twelfth places globally. Claude is third. Character.AI, Poe, DeepSeek and Grok fill fourth through seventh, Copilot is eighth and Perplexity ninth, and the tenth slot changes from month to month.

If you're watching Claude, its third place comes with a catch: it's outside the global top 20. No position on the list looks more under-monetized to me. Anthropic keeps consumer MAU private, and most of Claude's growth comes from enterprise API use and Claude Code. So the consumer product at claude.ai is smaller than its enterprise presence would make you think.

Keep Perplexity's ninth place in mind when you read Perplexity press. Its growth is real, and earlier reporting put core search at roughly 30M MAU. Next to ChatGPT and Gemini, though, the consumer product is still small. Perplexity hopes the Comet browser and Perplexity Computer will grow its ecosystem past a single URL.

RANKCONTROL

How often does ChatGPT mention your brand?

Most founders have no idea. The answer might surprise you.

Show me my mentions→50 queries tracked · all 6 AI models

Implication 1: rebalance distribution away from publisher mentions

Does your content budget still go mostly to placements in Forbes, TechCrunch, Business Insider and similar tier-1 outlets? Then you're paying too much for a channel whose returns at the top of the funnel keep shrinking. The declines in the shift above apply to every mention you buy there, and the traffic each one sends you is falling in real time.

Put the money where the growth is. That means Reddit (+21%), LinkedIn (rising, and quoted a lot by AI engines), YouTube (still second overall) and AI-answer citations themselves. The Stacker + Scrunch 239% median lift study points the same way. The earned media that still works is the kind that feeds citation share in AI answers, rather than sending readers to the publisher.

Implication 2: ChatGPT and Gemini are distribution channels

Is ChatGPT somewhere you get traffic from, or only somewhere people get answers? An r/SEO thread worked through that at the tactical level:

When OpenAI started showing more source links inside ChatGPT, referral traffic rose 150%, according to Similarweb's case study coverage. That tells you ChatGPT sends visitors as well as answering questions. If your content is cited in its answers, the referral yield you get is real, and it's growing.

So for the second half of the year, your AEO KPI stack should cover:

• weekly citation share on ChatGPT and Gemini, from our own tracking, Ahrefs Brand Radar or the AI Performance report in Bing Webmaster Tools
• referral traffic split by AI source, using GA4 or another analytics tool
• direct pageview attribution for the pages AI engines cite

Implication 3: the mention economy is now on Reddit, LinkedIn and YouTube

This is the implication that changes your weekly routine if you publish listicles and comparison posts. The biggest publisher categories, Wikipedia, traditional news and regional search, are shrinking. Reddit, LinkedIn and YouTube, the biggest social and community platforms, are growing and getting cited more often by AI engines. So each listicle or comparison you ship should come with a Reddit seeding plan and a LinkedIn post under a named expert's byline, plus a YouTube summary where it's relevant.

Why make it a first-class decision? Reddit is 21% bigger than a year ago and Wikipedia is 7% smaller. A dollar you spend on Reddit-native content, or on seeding that suits Reddit, goes meaningfully further than one spent on long-form encyclopedic content in the Wikipedia style.

For a SaaS company shipping 30-40 pieces a quarter, the split looks like this:

In 2024 the playbook used Reddit and LinkedIn to amplify content that relied mainly on Google organic for distribution. The June ranking turns that around. Reddit and LinkedIn now do the primary distributing, and Google organic is one retrieval target among several further down the line. The flip matters because it reorders which platforms get your optimization effort first and which brand voice patterns get your investment.

The category-level breakdown

Zoom out from individual sites to whole categories, and the June ranking tells the same story:

For your content strategy, that adds up to three rebalance moves. Content built to be picked up and syndicated like news is aiming at the worst primary distribution target there is. That channel compressed 20%+ over the past twelve months, and it will compress further.

Content that AI answers can't easily cite misses the category growing 40% entirely, so structure yours for ChatGPT, Gemini, Claude and Perplexity. And any mention-economy work you do belongs on social. In the Stacker + Scrunch earned-media analysis, mentions on Reddit, LinkedIn and YouTube returned the most per mention.

In short, shift your distribution toward AI Chatbots and social, which are growing, and away from news and regional search, which are shrinking. June's rankings let you measure that rebalance instead of guessing at it.

The bigger picture

Why does this month matter more than the category reports that came before it? No monthly ranking before this one showed the AI-era redistribution right at the top. In early 2024, ChatGPT in fifth, Gemini in twelfth on 209% growth and Wikipedia down in eleventh for the first time in a decade would all have seemed unimaginable.

For you as a SaaS founder, the ranking translates into a distribution rebalance. Cut back on publisher mentions and seed more on Reddit and LinkedIn. Track your citation share in AI answers more closely, and get comfortable treating ChatGPT and Gemini as first-class inbound channels.

The operational pipeline behind these citation dynamics is what our content engine covers. For the wider strategy view of AI search in the first half of the year, read The 2026 State of AI Search: RankControl's Annual Report.

Expect the ranking to keep moving. The third quarter will likely be when Gemini enters the global top ten, with ChatGPT moving up to fourth or better. Some of it is already permanent as of June. AI platforms have become durable destinations in the global top 25, and Wikipedia and traditional publishers no longer anchor top-of-funnel visibility. Plan for that, and track your citation share weekly so the data drives your next quarterly rebalance.

If you're reviewing this month, five checks are enough:

People will study the June 2026 rankings for years, because they mark the moment you could first measure the AI-era distribution shift among the biggest sites. Ship the rebalance in the third quarter, and by the first quarter of 2027 you'll be meaningfully better placed than founders who wait for the trend to settle.
