The visitor AI sends is worth more, and SEO is being bought
In one year, the traffic AI assistants send to US retail sites went from less valuable to more valuable than the rest. Meanwhile Adobe bought Semrush for 1.9 billion dollars to sell visibility inside AI answers.
42% better

Short answer: two signals arrived in the same season and they say the same thing. The visitor an AI assistant sends to a retail site now buys more than the others, and the money of the search optimisation industry has reorganised around that visitor. The first shows in Adobe's traffic data, the second in a 1.9 billion dollar acquisition. Neither says how many of these visitors there are, and that is the question to keep in mind.

AI traffic to US retail sites between October 2024 and May 2026 (Adobe)
A visitor who arrives after talking to an AI has often already compared. They are not coming to look, they are coming to buy.
In one year, from worse to better
According to Adobe's quarterly report, as reported by TechCrunch on 16 April 2026 and built on more than a trillion visits to US retail sites, traffic from AI assistants converted 42% better than the rest in March 2026. A year earlier, in March 2025, it converted 38% worse. Revenue per visit made the same swing: 37% above ordinary traffic in March 2026, when twelve months earlier the ordinary visitor was still worth 128% more.
The simplest explanation, and it is an interpretation, not a measurement: the conversation with the assistant does part of the salesperson's work. The customer compares, asks questions, rules options out, then clicks. They land on the site with the decision half made.
How many are they? Nobody says
Adobe publishes striking growth rates: plus 269% year on year in March 2026 according to its 20 April release, plus 1,324% between October 2024 and May 2026 according to its 17 June release, and plus 2,215% for travel over the same period. None of these releases gives the share of this traffic in the total. A growth rate says nothing about size: multiplying a small thing by fourteen can still give a small thing. That is the caveat missing from most articles that repeat these figures.
The search optimisation industry is being bought
On 19 November 2025 Adobe announced the acquisition of Semrush at 12 dollars a share, about 1.9 billion dollars. Semrush is one of the most widely used search optimisation tools in the world. Yet Adobe does not present it as an SEO tool but as a brand visibility platform providing generative engine optimisation (GEO) and SEO solutions, and justifies the deal by one need: remaining discoverable in AI search. The acquisition closed at the end of April 2026, and on 17 June Adobe launched a product, Adobe Brand Visibility, combining Semrush's AI visibility data with its own content tools.
That is the economic signal of the season: a marketing software vendor is betting nearly two billion on the idea that visibility inside AI answers has become a budget line of its own. It must also be read the other way round: whoever publishes the AI traffic growth figures is whoever sells the remedy. That does not make the data false, but it does not make it neutral.
The weak point sits on the website
The same report, again according to TechCrunch, adds a less discussed finding: around 34% of product pages on the retail sites studied cannot be properly read by an AI, and about a quarter of homepage content is not prepared for it. In other words, the most valuable visitor of the moment arrives through a channel that misreads one page in three.

And for a local business
These data cover online retail, not the tradesperson or the neighbourhood practice, and they should not be transposed as they are. But the mechanism does transpose. For a local business, conversion is not a completed basket, it is a call, a quote request, a visit. If the assistant does the comparing beforehand, the contacts that arrive are fewer and better qualified, and the ones that do not arrive were lost inside an answer the business never saw.
What this reading does not prove
That AI traffic weighs a lot.
None of the sources cited gives its share of the total. Growth is strong, size remains unknown to the reader.
That we verified the conversion figure.
It comes from Adobe's quarterly report as cited by TechCrunch; the report did not respond to our attempts to read it, and we say so rather than stay silent.
That the measurement is neutral.
Adobe now sells an AI visibility product. Its traffic figures also serve its sales pitch.
That online retail tells the truth about local services.
A basket and a quote do not behave the same way. Transposing to local is reasoning, not measurement.
What it changes
Count contacts, not only visits.
If AI does the sorting beforehand, volume falls and quality rises. A dashboard that only watches traffic will read good news as bad news.
Make your pages machine-readable.
One page in three misread on well-equipped retail sites: a local site with no technical budget is likely to do worse.
Distrust figures without a denominator.
A plus 1,324% without the share of the total justifies no budget on its own.
Know what AI says about you before paying someone to change it.
The big vendors now sell visibility inside AI. The first step, reading what assistants answer about your trade and your city, costs nothing.
