More than three in four shoppers already use AI to help them buy. Knowing how to optimize for AI search helps an assistant send them your way.

The short version

More than three out of four American shoppers used AI to help them shop in the past six months: 77.6%, from a Search Engine Land report on a survey of 1,009 US consumers. If you sell anything, odds are many of your customers checked with an assistant before they ever reached you.

Assistants are starting to do more than point. NielsenIQ and Similarweb, two firms that track what people buy and where they go online, put it plainly in a September 2026 announcement:

"AI agents are moving beyond product discovery to become part of the purchase itself." — NielsenIQ and Similarweb, September 2026

That puts learning how to optimize for AI search on the same list as keeping your hours and prices up to date. The people who measure shopping for a living are still catching up, too: the same announcement noted that current measurement tools cover retail, ecommerce, search, and media, but don't fully capture purchases that run through AI. If the professionals can't see the whole picture yet, most business owners can't either.

What an AI agent is, in plain terms

An AI agent is autonomous software that can take action for you, like placing an order or booking an appointment. Think of it as a personal shopper you send out with a list and your card: you tell it what you want, it compares options, and it can check out on your behalf.

Most people aren't ready to hand over their card yet, and the 31% who say they never would make that plain. Everyone else sits somewhere between "help me choose" and "go ahead and buy it."

For a business owner, both groups lead to the same place. The assistant builds the shortlist either way, and whether it buys or the customer clicks through afterward, you have to be on that list.

Short questions come from people ready to buy

ChatGPT gets about 2.5 billion prompts a day and searches the web on roughly 30% of them, which works out to around 750 million web searches a day, and a lot of them come from people trying to get something done. Semrush looked at which prompts send ChatGPT out to the web, and the pattern is clear: search-triggering prompts run short, while the ones it answers from what it already knows run longer. Most of the short, search-style prompts are navigational or transactional: people trying to reach a specific site or complete a task, like booking or buying.

Picture the customer at a coffee counter who says "large, black, to go." They've already decided and only need someone to sell it to them. A short prompt to an assistant often comes from that same type of customer, and a page that can't answer a short, specific question fast loses that customer to whichever competitor's page can.

How to optimize for AI search when AI does the shopping

AI search optimization means making your business easy for an AI assistant to understand and recommend. For online stores, this gets called ecommerce AI search optimization; for a local shop or service business, it works the same way with a map pin attached. An assistant can only recommend what it can read and check, so start with these:

Final thoughts

Go back to that 77.6%. For a long time, shopping meant walking past a window or scrolling a page of results while the store did the persuading. More and more, it means typing one short sentence to an assistant and trusting what comes back.

We work on this every day, building the first impressions that businesses and SaaS companies hand to assistants that read a website faster than any customer ever will. The owners who do well here are the ones whose facts are easy to read and easy to trust.

Common questions

How many shoppers use AI to help them buy?

77.6% of US shoppers used AI to help them shop in the past six months, according to a Search Engine Land report on a survey of 1,009 US consumers.

Will AI shopping agents actually spend money for people?

Some will, but most shoppers aren't there yet. 31.21% of respondents in the same survey said they would never let an AI spend any of their money autonomously. Everyone else sits between letting it build a shortlist and letting it complete the purchase.

What is AI search optimization for ecommerce?

It means making your product pages, prices, and buying process easy for an AI assistant to read and recommend, the same idea as traditional SEO but aimed at an assistant summarizing your site instead of a person scanning it.

Why are prompts that trigger a web search shorter than other prompts?

Semrush found that ChatGPT prompts triggering a web search average 8.7 words, versus 13.5 words for prompts answered from memory. Short prompts tend to be navigational or transactional: someone trying to reach a specific site or complete a task like booking or buying, rather than asking an open-ended question.

How do I check if AI assistants recommend my business?

Ask ChatGPT, Gemini, and similar assistants a question a real customer would ask, such as "where can I buy [your product] in [your town]?" and see whether you're named. Jumpstart GEO's free AI visibility audit runs this check across the major engines.
