What the new Similarweb study reveals about ChatGPT and website traffic
A study published by Similarweb in July 2026, titled «The Downstream Impact of AI Visibility,» confirms with real data something many B2B SMBs suspected but couldn’t measure: being recommended by ChatGPT makes a user 2.5x more likely to visit your website within the next 7 days, compared to brands that aren’t mentioned by the AI.
What makes this study relevant is the methodology: it isn’t based on estimates or recall surveys, but on real clickstream data from a US desktop panel, covering July to December 2025 plus a January 2026 survey. Similarweb analyzed three verticals – finance, travel, and beauty – and found the same pattern consistently: being cited by a generative AI isn’t just a branding win, it’s a measurable acquisition channel.
The number almost nobody is watching: 56% arrives through branded search
The most important finding for a B2B SMB isn’t the 2.5x figure itself, but how that visit actually happens. When ChatGPT recommends a brand, the user doesn’t always click a link inside the answer: in 56% of cases, they open Google (or their search engine of choice) and search for the brand name directly, compared to about 40% for standard browsing behavior.
In the finance vertical, for example, when American Express was recommended by the AI, 7.2% of users ended up visiting its site, versus 3.1% for Capital One under comparable conditions. The difference isn’t just about who gets mentioned, it’s about who wins the branded search that follows.
This changes the priority for an SMB: it isn’t enough for an AI agent to mention your name. If searching your brand on Google shows you poorly ranked, with an outdated Google Business Profile or no clear website confirming who you are, you lose the traffic the AI just handed you for free. It’s worth checking whether your clients are searching for you on Google or asking an AI, and whether your presence covers both scenarios.
How to get ChatGPT to recommend your B2B SMB
Language models don’t recommend brands at random: they cite what they find structured, verifiable, and repeated across different sources. For a B2B SMB in Chile or Brazil, this means working on three concrete fronts:
- Content with direct answers: pages that answer specific questions in your niche (pricing, comparisons, «how to choose a supplier for X») in plain language, backed by data, without filler.
- Third-party mentions: Google reviews, industry directories, press coverage, and external comparisons. LLMs weigh what others say about you far more heavily than what you say about yourself.
- Brand consistency: the same name, description, and contact details across your website, social profiles, and directories. Inconsistencies lower the confidence a model assigns to your brand as a citable source.
If you want to go deeper on the technical side of this work, we already covered the 7-step GEO guide to get ChatGPT to cite your B2B business, which details how to structure content so AI engines treat it as a source.
How to measure the traffic AI is already sending you
Most B2B SMBs still don’t separate traffic coming from ChatGPT, Perplexity, or Gemini from the rest of their referral traffic in reports. In Google Analytics 4, check the «Referral» channel and filter by domains like chatgpt.com, perplexity.ai, or gemini.google.com: today that number is probably small, but according to the Similarweb study it’s going to grow, and if you don’t measure it now, you won’t be able to prove the return on your content investment when it’s questioned.
It’s also worth monitoring how often your brand shows up in ChatGPT’s answers when someone asks about suppliers in your category. You can do this manually every week with prompts like «best [your industry] companies in Chile» or «how to choose a [your service] provider,» recording whether you appear, in what position, and with what description. If you’re also investing in paid media on these platforms, this pairs well with what we already covered on costs and preparation for ChatGPT Ads in 2026: paid advertising accelerates visibility, but the Similarweb study confirms the model’s organic recommendation is still what generates the most trust with users.
What to do this week
You don’t need a full digital strategy overhaul to capture this opportunity. This week:
- Search for your brand on Google and check whether your profile, website, and social accounts are aligned and up to date.
- Test 3 to 5 prompts relevant to your industry in ChatGPT and note whether your company shows up.
- Set up a segment in GA4 to isolate traffic coming from AI platforms.
- Review one key page on your site (services or pricing) and rewrite it to directly answer the question a customer would ask an AI.
The Similarweb study is the first hard evidence that AI visibility already translates into real, measurable visits. B2B SMBs that start optimizing for this today will capture an advantage that will be far more expensive to win a year from now.
