ChatGPT vs Gemini for SEO: Which Drives More Traffic?

ByTyler Ziton

ChatGPT beats Gemini for SEO traffic today. Statcounter’s March 2026 data shows ChatGPT sending 78.16% of all AI chatbot referrals to websites, against 8.65% for Gemini. Gemini is growing faster and sits inside Google, Android, and Chrome, so chase ChatGPT for clicks and Gemini for reach.

How ChatGPT Sends You Traffic

ChatGPT sends you traffic as a destination: a shopper opens the app, asks a question, and clicks one of the links in the reply. Those visits land in your analytics as referrals from chatgpt.com, so they are easy to count.

To be eligible for those links, your site has to let ChatGPT’s search crawler in. OpenAI’s help page on ChatGPT search says to allow OAI-SearchBot, and adds that ChatGPT sometimes partners with other search providers and rewrites your question into several narrower searches before it answers.

Links are also showing up in more replies than they used to. Similarweb’s tracking found the share of US ChatGPT answers that include a citation rose from 1.6% in June 2025 to 6.8% in May 2026. That’s still a small slice, and the biggest shares went to travel and automotive questions.

Where those clicks land changed this year too. Similarweb found that after ChatGPT’s May 2026 redesign, homepages went from roughly 26% to 29% of its referral traffic to about 62%. More than half of the shoppers ChatGPT sends you now arrive on your homepage, so that page has to route them to the right collection fast.

So the pages that win in ChatGPT are the ones that answer a buying question head on. “Best of” roundups, comparison posts, and product pages with clear specs get cited far more than brand stories, and I cover the full list of moves in how to rank on ChatGPT.

How Gemini Sends You Traffic

Gemini sends you traffic as a layer on top of Google: most people meet it in AI Overviews, AI Mode, the Android assistant, or the Chrome sidebar, and only some open the Gemini app. Google said the Gemini app passed 1 billion monthly users in August 2026, so the audience is there even when the click isn’t.

The tracking works differently too. A click from the Gemini app shows up as a referral from gemini.google.com. But a click from an AI Overview or AI Mode is counted as regular organic search, since Google’s documentation says traffic from its AI features is included in the Web totals in Search Console.

That means Gemini’s real influence is bigger than its referral line. Your store can be named in an AI Overview a thousand times a day and see none of it labeled as Gemini.

Google has the advantage of integrating Gemini across its ecosystem: Search, Android, Workspace and Chrome.

That line is from Statcounter’s CEO, Aodhan Cullen, and it explains the growth curve. Because Gemini pulls from Google’s own index, the work that gets you cited is mostly the work that gets you ranked, and I list the steps in how to rank in Google Gemini.

What Each One Wants From Your Pages

ChatGPT wants a single page that answers one buying question completely, and Gemini wants a site that covers the whole topic. That difference comes from where each one looks.

On the ChatGPT side, the model runs a handful of narrow searches and quotes the clearest page it finds, while Gemini leans on Google’s long record of which sites are trusted on a subject.

For a store, the ChatGPT version of that is a “best heated jackets for women” post with named products, prices, and a plain verdict for each. One strong page like that can get your brand named, even on a small site.

The Gemini side looks like the cluster around that post. You’d have the collection page, the sizing guide, the care guide, and four or five posts that answer the next questions, all linked together. Write the one page ChatGPT can quote first, then build the cluster Gemini trusts around it.

ChatGPT vs Gemini for Clicks You Can Measure

ChatGPT wins for clicks you can measure, and it isn’t close yet. Statcounter tracks which AI chatbots send visits to websites, and its March 2026 numbers put ChatGPT at about nine times Gemini’s share.

AI chatbotShare of referrals, March 2026Share in April 2025
ChatGPT78.16%Not reported
Gemini8.65%2.31%
Perplexity7.07%12.07%
Copilot3.19%Not reported
Claude2.91%0.30%

The second column is where the story is. Gemini nearly quadrupled in eleven months and passed Perplexity for second place, while Perplexity lost about 40% of its share.

For your store, that table sets the order of work. Fix your ChatGPT visibility first, since it sends about eight of every ten AI chatbot visits. Then watch the Gemini line each quarter, since it is the only one climbing that fast.

ChatGPT vs Gemini for Reach

Gemini wins for reach, since it rides on products people already open every day. Similarweb’s data on visits to the AI tools themselves shows ChatGPT falling from about 76% of worldwide traffic in June 2025 to about 53% in May 2026, while Gemini rose from under 9% to about 27%.

On top of that, those figures only count visits to gemini.google.com and the app. They leave out every AI Overview and AI Mode answer inside Google Search, which is where most shoppers see Gemini’s writing without knowing the name.

Reach matters even when you can’t count the click. A shopper who sees your brand named in an AI Overview on Monday may search your store by name on Thursday, and that sale shows up as branded search or direct traffic.

Gemini’s reach also grows without shoppers choosing it. Nobody has to download anything to see an AI Overview, and every Android phone and Chrome window carries a Gemini button. ChatGPT has to win each user, and Gemini inherits Google’s.

That’s why I don’t judge Gemini by its referral line alone. I check whether the store’s name shows up in AI Overviews for its ten most important questions, and I watch branded search in Search Console for the lift that follows.

How Do You Track ChatGPT and Gemini Traffic Separately?

You track ChatGPT and Gemini traffic separately in GA4 by filtering session source for chatgpt.com and gemini.google.com. Open Reports, then Traffic acquisition, switch the table to session source, and type each domain into the search box. It takes about a minute, and it works on data you already have.

Once you’ve found both rows, compare three numbers for each: sessions, engagement rate, and revenue. On most stores I look at, the ChatGPT row is several times larger and the Gemini row is newer and growing.

Just know the Gemini row will always run low. It only counts clicks from the Gemini app and site, and every click from an AI Overview or AI Mode is filed under organic search instead. To see that hidden part, watch Search Console for question keywords where impressions are climbing while clicks stay flat, since that pattern usually means an AI answer is sitting above your result.

If you want a permanent view, build a custom channel group in GA4 with one rule that matches the AI domains. GA4 applies it to past data too, so your history fills in the moment you save it.

Which Visitors Buy More?

Visitors from ChatGPT and Gemini both engage more than other traffic once they land, and their buying rate has caught up. Adobe measured AI referrals to US retail sites and found a 23% lower bounce rate, 12% more pages per visit, and 41% longer visits than other traffic by February 2025.

The conversion gap in that data was closing fast. In July 2024 an AI visitor was 43% less likely to buy than other visitors, and by February 2025 the gap was down to 9%. Adobe’s later releases have AI visitors pulling ahead, and I go through those numbers in do AI citations convert into customers.

Adobe doesn’t split those numbers by chatbot, so nobody can tell you from public data that a ChatGPT visitor beats a Gemini visitor. Your own GA4 can tell you, though. Build one channel for AI referrals, break it out by source, and compare revenue per visit after 90 days.

I’ve seen the ChatGPT side turn into dollars on a client store. At Exclusive Beauty Club, ChatGPT revenue grew 2,234% from April 2025 to April 2026, and the Exclusive Beauty Club case study shows the pages behind it.

Can You Optimize for Both at Once?

Yes, you can optimize for ChatGPT and Gemini at once, since about 80% of the work is shared. Both want a page they can crawl, an answer in the first sentence, and a brand that other sites mention. These five steps cover both:

  1. Allow OAI-SearchBot in robots.txt and check that nothing blocks Googlebot.
  2. Submit your sitemap to Bing Webmaster Tools as well as Google Search Console.
  3. Rewrite the first paragraph under each heading on your top ten pages so it answers the heading.
  4. Publish one “best [product] for [use case]” post for each of your main collections.
  5. Earn mentions in roundups, review videos, and forum threads in your category.

None of those steps is specific to one tool. A robots.txt fix helps every crawler, an answer-first paragraph is what both models lift, and a mention in a trusted roundup feeds ChatGPT’s searches and Google’s view of your brand in the same week.

Step 2 surprises people. ChatGPT leans on outside search providers, so a page that Bing has never seen can be missing from its answers, and I explain the evidence in does ChatGPT use Bing.

Where the two split is the last 20%. ChatGPT rewards single pages that answer one buying question well, and Gemini rewards a site that covers a whole topic, since it inherits Google’s view of your authority. That split is how I plan a store’s AI search work: money pages first for ChatGPT, then topic clusters for Gemini.

Which Is Better for Doing SEO Work?

Gemini is better for SEO research and ChatGPT is better for SEO drafting, if your question is which tool to work in. Gemini is wired into Google’s products, so it can work inside Sheets on a Search Console export and pull from live Google results. ChatGPT is the stronger writing partner for outlines, rewrites, and metadata.

Can Either One Replace an SEO?

No, neither ChatGPT nor Gemini can replace an SEO, though both can take hours out of the week. They write a fine first draft and a poor strategy, since neither knows your margins, your stock, or which keywords turned into orders last year. That gap is the same one I’d expect from any assistant, whichever company built it. I ran the same question on a third model in can Claude do SEO.

Which One Is Better for Keyword Research?

Gemini is better for keyword research, but only as a starting point. It can summarize what ranks today and group a Search Console export by topic in a few seconds. Neither tool has real search volume, so check any keyword list against Search Console or Google’s own autosuggest before you build a page around it.

Should You Publish What They Write?

No, you shouldn’t publish what ChatGPT or Gemini writes without editing it. Use the draft for structure, then add what the tool can’t know: your product details, your customers’ questions, and numbers from your own store. A page with first-hand detail gets quoted by both tools, and a page that reads like either one wrote it gets skipped.

Which Should You Pick?

Pick ChatGPT first if you sell products people research before buying, and add Gemini once your ChatGPT basics are done. Here is the short version:

  • Pick ChatGPT first if you want AI traffic you can see in GA4 this quarter, you sell considered purchases, and you already have product pages and “best of” posts worth citing.
  • Pick Gemini first if most of your revenue already comes from Google, your blog ranks for questions, and AI Overviews are showing up on your main keywords.

Most Shopify stores I talk to fit the first line. They have the pages, and the pages just aren’t written so a chatbot can quote them.

Whichever line fits, give it one quarter before you judge. Set a baseline today: your ChatGPT referral visits in GA4 and a list of which brands each tool names for your five main buying questions. Check both again in 90 days, and you’ll know which platform moved.

Get Cited on Both

ChatGPT drives more clicks today and Gemini reaches more people, so the plan that holds up is the one that serves both from the same pages. If you want to see where your store stands, book a call and I’ll run your top buying questions through ChatGPT and Google with you and show you who gets named instead of you. If you’d rather hand it off, my AI search services cover both platforms.
