Grok is already a search engine. It sent our 12 sites one visit in 15 months.

What just happened, and why this week matters

On 2 September 2026 Elon Musk posted that "Grok 4.7 comes out in 10 days", which points to around 12 September. He claims 2.1 trillion parameters, about 40% more than 4.6. Treat that as a promise, not a product. As of 5 to 8 September xAI's developer docs still listed 4.6 as the newest model, with no model ID, price or benchmark card for 4.7, and Grok 4.5 shipped 46 days late and 4.6 five days late.

What has shipped is the plumbing: Grok 4.6 on 12 August 2026, Grok Bot, xAI's autonomous agent, in beta from 11 August, and a native X connector on 29 August that searches posts and checks mentions.

Why should a barber in Kent care about a model number? Because a launch is usually when people try a chatbot they had ignored, and the answers they get come from whoever is already indexed. Julian Goldie's Grok SEO case study of 14 August 2026 says a page on a topic trending on X, indexed fast, reached page 1 of Google within 24 hours and was then cited three times in one Grok answer. That is his claim, not independently verified, but the local lesson holds: your pages and posts have to exist and be indexed before the surge, not after.

Is Grok actually a search engine?

Yes, in everything but name. Grok has two retrieval tools, web search for the open web and X search for live posts, and the model decides for itself when a question needs one. When it does, it runs an agentic loop: it reads the first results, fires follow-up searches, then writes an answer with numbered citations. And you cannot reliably block Grok with robots.txt, so the choice is not whether it reads your site but whether what it reads is worth citing.

The audience is not small. SpaceX's Q1 2026 filing put Grok at 117 million monthly active users, as reported by DemandSage. That is up from about 35 million in December 2025 on Similarweb's reported figures, and the same round-up says only about 23% of grok.com traffic is from the US. No UK-specific Grok figures exist. Grok is free inside X and at grok.com, with limits, so nothing stops your customers trying it this weekend.

How does Grok decide what to cite?

The best public evidence is a third-party study by Presenc AI that sampled 4,400 prompts hourly through March and April 2026. Its reported findings:

Shares as reported by the study. The sub-categories are rounded, so the web rows do not sum exactly to its headline 55%.

So roughly 45% of what Grok cites is an X post and 55% is a web page. Posts from verified accounts were cited 2.8 times as often as equally engaged unverified ones, though we have not tested whether paying for a tick helps a local account: post the facts first, decide on the tick later. Likes help, but the big lifts start at 5,000 or more, which is not a local business's game. The same study puts Grok at 4.7 sources per answer on average, against 5.8 for Perplexity and 4.9 for Google's AI Overviews, so each slot is worth more.

Two caveats. This is one study, updated quarterly, so treat the numbers as reported rather than settled. And it has no local-business or near-me findings, nor have we seen any published elsewhere. We do not know what Grok does when someone in Tunbridge Wells asks for a barber, so this month we are starting to run our own prompts, described below.

Does Grok send traffic to websites yet?

Barely, and that is the point. On 9 September 2026 we pulled AI-assistant referrals from Google Analytics 4 for the 12 websites we own or look after: sessions from chatgpt.com or chat.openai.com, perplexity.ai, gemini.google.com, claude.ai, copilot.microsoft.com and grok.com.

Four sample months from a 15-month pull. Grok's share of every row: zero, apart from a single visit in August 2025.

In the last 30 days, 10 August to 8 September 2026, that was 274 AI sessions out of 18,309, or 1.5% of all visits. Over 90 days it was 483 sessions, about 420 of them from ChatGPT. Grok sent none in either window. So the AI channel is real, August 2026 was 2.3 times August 2025, and one engine with a reported nine-figure audience is contributing nothing to it yet.

What is Grok SEO for a local business?

Grok SEO is making your business one of the sources Grok cites: a web page it can read and an X post it can find. For a barber, plumber, energy assessor or holiday let, both are within reach. News sites and high-authority domains take the biggest slice of Grok's web citations and you will not own either, but in that same study brand and company pages plus long-form blogs took 14%, and X posts took the largest share of all. Almost no local business is in the second pool.

ChatGPT already sends this kind of traffic, and we have written up how ChatGPT picks a local business separately. At The P2 Collective, a barbers in Tunbridge Wells, 43 ChatGPT sessions arrived in 90 days and 34 landed on the homepage: people asked for a barber and clicked straight through. UK Brewery Tours took 118, 12 of them to the gift-vouchers page.

The pages that get the click are homepages, voucher pages and town pages, not essays. For a plumber that means a page per service and per town. For a holiday let it means pages that answer what guests type: Field Cottage Peterstow, one cottage, is top 4 on Google for "National Trust near Ross-on-Wye", a question guests ask before they book. Those are the pages Grok's web search will find. If you would rather we did this, work with us.

What we're doing about it for our clients

The web half of our local SEO work is already running. The rest starts this month.

1. Fast static sites with structured data built in. FAQPage, BreadcrumbList and business schema, clean URLs, zero layout shift. Done for London Brewery Tour, EPC Near Me and Field Cottage Peterstow, among others.
2. Daily, AI-assisted, human-edited publishing around real questions. Every page answers its question in the first line. London Brewery Tour has run this since May 2025 and took 2,208 organic clicks in August 2026, 4.6 times August 2025.
3. Google Business Profile kept complete and active, with reviews encouraged and answered, as at The P2 Collective.

Starting this month:

4. Putting AI referrals in every monthly report. This week we pulled AI-assistant sessions, Grok included, from GA4 for every site we look after, and they go into client reports from September 2026.
5. Opening Google's new generative AI performance report for every client, and comparing AI impressions with classic ones page by page.
6. Running a fixed set of prompts of the "recommend me a barber in Tunbridge Wells" kind, in ChatGPT, Gemini and Grok for each local client, logging who gets named.
7. Publishing short, factual updates from clients' own X accounts, because Grok reads X.
8. Adding FAQ blocks with FAQPage schema for the questions owners hear on the phone, and matching Bing Places, Apple Business Connect, Yelp and Foursquare to the Google Business Profile.

What you should do this week

You do not need us for any of this. Six things to do before 4.7 lands, whenever that is.

1. Ask Grok about your own trade. Type what a customer would type: "recommend a plumber in [your town]", "best barber near [your town]". Note every business and source it cites, screenshot it and date it. That is your baseline.
2. Check GA4 for grok.com as a traffic source. Open the Traffic acquisition report, under Reports then Acquisition, switch the dimension to Session source and search for grok.com. Do the same for chatgpt.com. If Grok shows zero, you are where our sites are, and a zero today makes next month's number mean something.
3. Make your homepage answer the question in its first line. What you do, where, and for whom. "Emergency plumber in Tonbridge, same-day call-outs" beats "Welcome to our website".
4. Post one factual update from your business X account. Opening hours, a new service, a price, a finished job with a photo. Facts, not slogans. If the account has been dormant for years, start anyway.
5. Add an FAQ block for the five questions you hear on the phone. Do you do evenings? Do you charge for a quote? Is there parking? One or two plain sentences each.
6. Match your listings. Google Business Profile, Bing Places, Apple Business Connect, Yelp and Foursquare, with identical name, address, phone, hours and categories everywhere.

Common objections, answered

"Grok sends no traffic, so why bother?" Because small channels grow. ChatGPT alone sent our 12 sites 80 sessions in August 2025 and 187 in August 2026. Grok's line is still zero, and yet its reported audience had already reached 117 million monthly users by Q1 2026, up from about 35 million in December 2025. The cost of being early is an X post and an FAQ block. The cost of being late is a competitor's name coming up in answers instead of yours.

"I left X and I am not going back." Fair enough. Web pages are the bigger pool according to the one public study, so a clear, fast site with FAQ schema puts you in the larger half on its own. X is the half your competitors will ignore, so one factual post a week is worth it, but it is not compulsory.

"Should I wait for 4.7 before doing anything?" No. Nothing announced about 4.7 changes how Grok retrieves. Both of its search tools are live today, and if a launch-week surge comes, whatever is indexed by then is what gets cited. Grok 4.5 arrived 46 days late, so waiting could mean weeks.

The verdict

Grok 4.7 is a promise with a date attached, and the date may slip. Grok as a search engine is not: it is live, free to try, and reads the open web and X together. Across everything we look after it has sent one visit in 15 months.

We cannot promise you a citation. What we can do is put your business where Grok looks, on the web and, from this month, on X, then show you the GA4 and Search Console numbers every month with the Grok line included, even when it says zero.
