I’ve repeatedly made the declare that AI chatbot visitors converts higher than search engine visitors.
My pondering was that ChatGPT or Perplexity customers undergo analysis and exploration cycles (bear in mind the Messy Center) sooner and are nearer to a purchase order intent once they click on on an outgoing hyperlink.*
However I couldn’t show it at scale. Till now.
*In fact, there should be an affect of seeing manufacturers talked about in AI chatbots even with out a hyperlink, however that’s not the main focus of this examine.
To show this psychological mannequin proper or mistaken, Similarweb offered me with a big dataset of over 7 million referral classes from ChatGPT, Copilot, Gemini, and Perplexity with Google Search throughout September, October, and November within the U.S.
The information focuses on transactional referral visitors. Because of its trade dimension, I discover a heavy bias towards ecommerce, however the information additionally covers conversions like software program sign-ups.
Due to the Similarweb staff, particularly Lewis and Adelle, for supporting me with the info and your time.
Earlier than leaping in, I need to level out a giant caveat: AI chatbot referral visitors remains to be tiny in comparison with Google.
In How vital is AI chatbot visitors in B2B?, I discovered AI chatbot visitors to make up lower than a p.c of natural visitors at this time.
It’s rising at a speedy price and will catch up over the subsequent years, however actuality is that it’s nonetheless small.
AI chatbot visitors (in SaaS) – Picture Credit score: Kevin IndigIdentical ‘Ol, Identical ‘Ol
I need to begin with a have a look at the highest 10 touchdown pages as a result of it’s consultant of how to consider the remainder of the info on this examine.
About 80% of (transactional) visitors to prime the highest 10 touchdown pages goes to ecommerce websites.
And, it’s largely to the identical gamers you already know from (Google) Search as a result of AI chatbot solutions use search outcomes to floor (assume: weight) their solutions.
Prime 10 touchdown pages by visitors from referrer (Picture Credit score: Kevin Indig)Amazon, eBay, and Walmart dominate in Google Search simply as a lot as in AI chatbots.
Microsoft seems surprisingly typically within the prime 10 touchdown pages, apparently as a result of searchers are in search of software program like Copilot or Groups.
Considering one step additional, if search outcomes decide who’s seen in LLMs, the websites that dominate proper now may also dominate the AI world.
I’m skeptical that that is the way it will truly play out as a result of customers ask longer queries and have a conversational expertise in AI chatbots, which ought to enable LLMs to develop their very own “rating components.” What we’re seeing is the very first iteration.
AI Chatbot Site visitors Is Extra Engaged
The large query I’m attempting to reply is whether or not AI chatbot referrals convert higher than search visitors.
I checked out two metrics to match the visitors high quality of every referral supply: session period and the variety of web page views per session.
Excessive session period together with a excessive variety of (non-bounced) web page views means customers consider a product for longer and usually tend to purchase when taking a look at transactional visitors.
Avg session period by referrer (Picture Credit score: Kevin Indig)The development is crystal clear: AI chatbot referrals keep greater than a minute longer than Google visitors.
The entrance runner is Copilot, with a median of 11.6 minutes per session. On common, AI chatbot visitors stays for 10.4 minutes, in comparison with Google’s 8.1 minutes.
Avg session period and variety of non-bounced pageviews by referrer (Picture Credit score: Kevin Indig)To place session period into perspective, I wished to see if customers who keep longer additionally go to extra pages on a web site. The reply is “sure.”
AI chatbot referrals go to 12.4 pages on common, in comparison with Google’s 11.8.
Once more, extra pageviews inside the similar session correlate with a better likelihood of conversion when taking a look at transactional visitors, so this implies AI chatbot visitors has a better high quality.
The typical may not appear large, however fortunately, Similarweb despatched me information by month as nicely, so I used to be in a position to take a look at the development over time.
I discovered that the variety of non-bounced web page views from Copilot and Perplexity grew sooner than from Google between September and October: 15% and 22%, in comparison with Google’s 5%.
Gemini’s non-bounced web page views shrunk by -11% over the identical time and ChatGPT by -5%, which is cheap given its speedy visitors progress.
Session period vs. visits on chatgpt.com (Picture Credit score: Kevin Indig)Basically, it’s spectacular that ChatGPT’s session period grows whereas visitors is exploding. It implies that the fashions are getting higher at answering questions whereas extra persons are utilizing them.
Google’s session period and visitors are flat compared, however with the context that Google is a matured channel and magnitudes bigger than ChatGPT.
Complete visitors to Copilot vs. Perplexity (Picture Credit score: Kevin Indig)To my shock, Microsoft Copilot visitors reveals higher engagement than Perplexity, which has larger adoption and launched a selected ecommerce function (Store with Professional).
Copilot just isn’t as far-off from Perplexity as you would possibly assume (14 vs. 21 million visits in December 2024), and each noticed large visitors positive factors in October 2024.
I clarify this development with Microsoft’s roll-out of Copilot on all of its gadgets and software program merchandise.
AI Chatbots Ship Extra And Higher Site visitors To Homepages Than Google
To grasp the place AI chatbot referrals land and evaluate it to Google, I checked out folder depth as outlined by the variety of slashes in a URL after the area identify.
Increased folder depth = extra folders within the URL = “deeper” within the web site structure.
A seek for a transactional key phrase on Copilot (Picture Credit score: Kevin Indig)For instance, a seek for “greatest low cost fridge magnets” in Copilot leads you to www.amazon.com/Greatest-Sellers-Fridge-Magnets/zgbs/kitchen/3737161?type=MG0AV3, which has a folder depth of 4.
Discover how Copilot references solely Amazon outcomes, although Bing ranks Amazon No. 3 and No. 4 for the question.
The primary (Printrunner) and second outcomes (Uprinting) don’t permit you to purchase fridge magnets however to design them. Plainly Copilot understands that.
My concept was {that a} larger folder depth means extra visitors goes to particular merchandise (ecommerce) and touchdown pages (B2B).
If customers soar off of AI chatbots once they’re able to convert, touchdown on pages with a better folder depth ought to be a greater outcome than a class web page they must discover once more.
Understand that most websites have a comparatively flat structure.
Contemplate the homepage stage 0, a weblog folder (/weblog) or class web page stage 1, and merchandise/sub-categories/touchdown pages on stage 2 or 3. In fact, giant retailers like Amazon might considerably skew the outcomes as a result of it has so many sub-categories.
Folder depth of referral visitors (Picture Credit score: Kevin Indig)Folder depth for referral visitors varies considerably between the distinction referral sources, even amongst AI chatbots.
For instance, ChatGPT sends over 50% extra visitors to homepages than Copilot or Perplexity and over 3 times greater than Google Search.
You also needs to be aware that solely AI chatbots ship referrals to a folder stage of 8, which is the results of most websites not having as many ranges, extra so than desire.
I ponder in the event that they’d ship much more visitors deeper into web sites if extra websites had larger folder depth, which could not be ultimate for (Google) Search however perhaps for AI Search. We’ll want extra information to reply this query.
Avg folder depth with and with out Google (Picture Credit score: Kevin Indig)On common, AI chatbots ship extra visitors to the homepage than Google, which sends extra visitors to the second and third folder ranges.
Perplexity sends visitors the deepest with a median folder depth of two.45 in comparison with Gemini with 2.00 and Google Search with 2.33.
Share of visitors going to the homepage by referrer (Picture Credit score: Kevin Indig)ChatGPT sends most customers to the homepage with 30%, in comparison with the opposite referral sources, whereas Google sends the least with 10%. The typical for Gen AI referrals is 22%.
Nevertheless, it really works nicely for ChatGPT: Session period is larger than Google’s for referrals to non-homepages, and each web page views + session period are larger for homepage referrals than for Google Search.
Avg. pageviews and session period of homepage referral visitors (Picture Credit score: Kevin Indig)The information signifies that homepages are extra necessary within the “AI future” and that AI chatbots qualify customers higher earlier than sending them out.
This is a vital distinction to (Google) Search, the place homepages are sometimes not the most effective outcome apart from model searches.
To make this level even clearer, our data about transactional visitors within the outdated Search world is that customers are impatient.
As Adelle from Similarweb identified to me, AI appears to go counter to the age-old examine of “each second a web page masses sooner, it converts extra individuals.”
As an alternative, it pre-qualifies customers earlier than they go to a web site, which results in these customers being blissful to spend extra time.
Because of this, search engine marketing specialists, UX designers, and product managers have to rethink the function of homepages within the person journey and web site structure.
Deeper Content material Appears To Resonate Higher
Subsequent, I requested myself if we are able to see a relationship between the variety of phrases in a search question and the place customers land.
Sadly, we are able to solely measure the variety of phrases per question for Google Search, so I’m making a giant leap right here.
I strongly assume AI chatbot customers ask longer questions as a result of the expertise is extra “conversational,” which Sundar Pichai, Alphabet’s CEO, confirmed on a number of earnings calls:
Previously 12 months, we’ve answered billions of queries as a part of our Search Generative Expertise. Individuals are utilizing it to Search in solely new methods, and asking new forms of questions, longer and extra complicated queries, even looking with pictures, and getting again the most effective the net has to supply.1
With the idea that AI chatbots and outcomes “immediate” customers to seek for longer queries, I in contrast the variety of phrases per question with session period in relation to folder depth for Google Searches.
% visitors and session period by folder depth (Picture Credit score: Kevin Indig)Session period shrinks till a folder depth of 4, which is when it flattens out.
In different phrases, customers spend the identical time on a web site regardless of whether or not they go to a web page on stage 4 or stage 10.
That development leads me to imagine that they discover what they’re in search of on deeper ranges of a web site (when coming from Search).
Google referral visitors to the homepage vs. different pages (Picture Credit score: Kevin Indig)The identical just isn’t true once we have a look at the variety of phrases for referral classes to the homepage: Session period doesn’t flatten out however retains dropping with larger ranges of folder depth.
So, how can we carry this again to AI chatbots? The information for Google Search raises the query of whether or not AI chatbot visitors would interact even higher if much less went to the homepage.
Since AI chatbots perceive context so a lot better than (Google) Search, not less than outdoors of AI Overviews, sending customers to extra particular pages ought to be a greater expertise.
The rationale this isn’t taking place but may very well be that AI chatbots haven’t crawled sufficient of the net but and that search performance remains to be very nascent.
Conclusion: What It All Means
The adoption of AI chatbots goes extremely nicely.
ChatGPT has over 300 million weekly customers, Bing Chat appears to assist the forever-second search engine lastly achieve market share, and we’ve hit a staggering 72% of corporations that use AI in not less than one enterprise perform.2
Over 7 million referral classes from AI chatbots and Google Search reveal that:
- About 80% of transactional visitors goes to ecommerce websites, and the identical gamers (Amazon, eBay, Walmart) dominate each in search and AI chatbots.
- AI chatbot referrals present larger engagement: They keep 2.3 minutes longer on common (10.4 vs. 8.1 minutes) and examine extra pages (12.4 vs. 11.8 pages on common).
- AI chatbots ship considerably extra visitors to homepages (22% common) in comparison with Google (10%) however nonetheless present larger engagement.
- Copilot and Perplexity confirmed sooner progress in web page views (15% and 22%) in comparison with Google (5%).
The large query is whether or not corporations are keen to make an funding in AI chatbot visibility at this level with the potential reward of creating themselves as a first-mover however at the price of decrease short-term affect.
The early outcomes are promising, however loads can change till AI as a “channel” reaches important mass.
