While AI traffic is growing as a referral source, Google still dominates by a factor of 345x, and Reddit out-refers all three major AIs combined.
As it stands AI traffic isn’t making much of a dent, so is it worth pursuing?
Here’s what we know so far…
Sidenote.
Thanks to our data scientist Xibeijia Guan for aggregating all of the data behind this research.
But traffic isn’t the only thing that matters.
It’s also about awareness and conversions, and we’re seeing signs that AI can deliver on both fronts.
For instance, approximately 3% of our own conversions have come from AI over the last year, based on registration data, and qualitative “how did you hear about us?” responses.
Our new research shows that Perplexity has overtaken Gemini as a traffic referral source.
According to data from Kevin Indig, Perplexity is the AI most likely to cite a brand in its responses, which does a lot to explain this growth.
In the same study, Kevin reveals that brand mentions in ChatGPT correlate most with a site’s domain rating, while Perplexity and AI overview mentions correlate with deep content.
Sites receiving under 10K visits can now expect 0.3% of their traffic to come from LLMs, vs. 0.1% for those exceeding 1 million visits.
Smaller sites also tend to attract more traffic from AI than they do from email, while the opposite is true of larger sites.
One possible explanation for this discrepancy is that smaller sites and brands are less familiar to the user, resulting in more research-geared clicks.
But, even without tracking anomalies, AI traffic would be modest, because users are able to do more of their research without clicking.
The reality is AI drives significant brand awareness, creates more informed audiences, and delivers more qualified leads—it’s not just about traffic.
Wrapping up
AI is the shiny new thing. Everyone wants to get involved. But AI traffic is still minimal compared to more established channels—you risk over-investing if you get carried away by the hype.
Like social media keeps you on-platform sharing interesting content, AI keeps you on-platform having interesting conversations—sending out external traffic is not the goal.
For that reason, AI will never be one of the top referrers in your site analytics.
Its main benefits are increased brand awareness and positive brand sentiment, through on-platform mentions.
Trackable AI traffic and conversions are a happy byproduct—treat them as your secondary KPIs.
Before you commit to building your AI traffic, ask yourself: are my audience actually using AI to find my business?
Make a judgement call based on regional and vertical AI traffic usage, and your own customer data.
Once you’re confident your audience is there, track AI broadly and regularly.
