When will you see results from local SEO or AI search?

Maybe you paid for a new website, rewrote your service pages or hired someone to get you into AI answers. Now you want to know when the phone will ring more. That is a fair question. The honest answer is that no one can give you a date, and anyone who does is guessing.

That isn't because nothing happens. Results arrive in stages, and each stage runs on its own clock. Only the first one is fully in your hands:

1. The work is done. The page is live, the phone number is in the text, the towns you serve are listed and your Business Profile is up to date. You can check most of this the same day.
2. Search tools find it. Google, ChatGPT's search and Claude's search read the new version of your pages. This takes hours to weeks, and they set the pace.
3. Answers change. Google and the AI assistants start showing or naming you more often. Because answers vary from one run to the next, this shows up as a share across many answers, not a single moment.
4. Customers call. Calls, form requests and booked jobs rise. These also depend on the season, your prices, your competitors and how fast you answer the phone.

Google's own advice to site owners is that some changes take effect in a few hours and others take several months ¹. It suggests waiting a few weeks before judging whether a change helped in Google Search ¹. For AI assistants there is even less to go on. We found nothing from OpenAI, Anthropic or Google on how long a new page takes to change which businesses an assistant names.

So a useful plan has dates for checking the work and gathering evidence, not a date for success. This guide explains each clock and what our recorded answers show about change over time. Then it shows how to tell real progress from chance when calls are few.

Why nobody can give you an honest deadline

Each stage runs on someone else's clock

Start with Google. When you ask it to recrawl a page you changed, Google says crawling can take anywhere from a few days to a few weeks ². Asking again and again won't get the page crawled any faster ². Even then, a request doesn't guarantee the page will show up in results quickly, or at all ². Google doesn't promise to crawl, index or show any page, even one that follows all its rules ³.

Google's AI features sit behind that same step. To appear as a link in AI Overviews or AI Mode, a page must first be indexed and able to show a text snippet in Google Search ⁴. So a page Google hasn't indexed yet can't be one of their links.

Your Google Business Profile runs on its own clock. Google says edits usually take up to ten minutes to review, but sometimes up to 30 days ⁵.

ChatGPT gives one figure, and only about access. Your robots.txt file tells search tools which pages they may read. If it was blocking OpenAI's search crawler, OpenAI says its systems take about a day to adjust after you fix it ⁶. That is when ChatGPT is allowed to read your site, not when it starts naming you.

Not every change makes a visible difference

Google warns that not all changes to a website will make a noticeable difference in search results ¹. A page can be correct and complete and still not change who gets named. Assistants weigh other businesses, reviews, distance and what other sites say about you, too.

The answers move while you wait

AI answers aren't fixed lists. Ahrefs, a company that sells search tools, tracked Google's AI Overviews for more than 43,000 searches over a month. From one AI Overview to the next, nearly half of the cited sources were entirely new ⁷. Our own answers show the same restlessness in the businesses named, as the next section explains. A check before your change and a check after it can differ for reasons that have nothing to do with you.

The assistants themselves change

The companies update the models behind their assistants without asking anyone. In the six weeks of answers we recorded, two different models answered as ChatGPT and two as Claude. An update can move results for every business in your town on the same day.

Small numbers swing hard

Say your website brought four calls one month and six the next. That is a 50% rise, and it may be pure luck. Percentages built on a few calls, or a few AI answers, jump around far more than the business behind them. Keep the raw counts and what each one is out of, such as "6 calls from 210 website visits".

Other things change at the same time

Air conditioning calls climb when summer starts, and roofing calls jump after a storm. A new competitor opens, you raise prices, you turn on ads or a batch of reviews arrives. Any of these can move your calls more than a page edit does. If you don't write them down, a later rise or fall gets credited to the wrong thing.

What our recorded answers show about change over time

Between September 2 and October 14, 2026, we asked ChatGPT, Claude and Google AI Mode to recommend a local contractor 47,209 times: ChatGPT 19,577, Claude 16,358 and Google AI Mode 11,274. The questions covered HVAC, plumbing, electrical and roofing jobs in towns around Tampa Bay, Florida. Each was asked in a fresh conversation with web search on.

We didn't change anyone's website, and we don't know what the businesses changed during those weeks. So these answers can't show how long a change takes to work. They show something just as useful: how much answers move on their own. Any result you hope to see has to stand out from that background. These are observations of answers, not experiments.

We counted a business as named when the answer set its name in bold, treating close spellings as the same business. Google AI Mode's answers in our records don't mark names that way, so the figures on names cover ChatGPT and Claude.

The same question, two weeks later

Many identical questions were asked again, typically about 14 days later. On average, only 43% of the businesses ChatGPT named the first time were named again. For Claude it was 26%. If you checked once, waited two weeks and checked again, most of the names could be different even if nobody had changed a thing.

Over a month, the picks drift, not just by chance

Some of that change is luck. To see whether answers also shift over time, we took questions asked of the same assistant both before and after September 23. We paired each question's earliest answer with its latest one, then grouped the pairs by trade and town. For every business named in at least 20% of a group's answers, we compared its share of the earlier answers with its share of the later ones.

Then we tested what chance alone would do. Within each pair, we swapped which answer counted as earlier, at random, 200 times. If only luck were at work, the real gap would look like those reshuffled gaps.

• ChatGPT: across 32 pairings of a trade and a town, typically 100 paired questions each and about 28 days apart, a business's share of answers typically moved 11 points. Reshuffling gave about 4 points. For 59% of the businesses, the move was bigger than nine in ten reshuffles produced.
• Claude: across 32 pairings, typically 66 paired questions each and about 21 days apart, the typical move was 13 points against 5 points from reshuffling. For 52% of the businesses, the move was bigger than nine in ten reshuffles produced.

If chance were the whole story, only about one business in ten would clear that bar. Far more did. So over three or four weeks, the businesses assistants name shift for reasons beyond luck. Those could be model updates, new pages on the web or changes the businesses made. We can't tell which.

With only a dozen or so answers, this drift is buried in chance. It shows once there are dozens of paired answers on each side. For you, the lesson is plain. Your share can rise or fall within a month with no change on your side. A simple before-and-after check can't separate your change from that drift. Comparing with jobs or towns you didn't change can help, as the next section explains.

How many answers it takes to see a real change

Standard statistics show how rough a small sample is. With 10 answers, a business named in half of them could really be named anywhere within about 26 points either side of that. With 30 answers the range is about 17 points, and with 100 answers about 10 points.

Telling a change apart from chance takes more again. Say you were named in 20% of answers before a change. To be fairly sure a rise to 40% is real, you would need about 82 answers before and 82 after. To confirm a smaller rise, to 30%, you would need about 294 on each side. Petra Labs, a company that sells AI visibility tracking, found the same problem. With 100 runs, a real 5-point change was caught only 11% of the time ⁸.

Checking more often can look like growth

We didn't collect the same number of answers every week. In our five full weeks, the weekly total ranged from 6,689 to 8,592, a difference of 28%. A report that counted raw mentions would show growth in the busier week with nothing else changing. Every count needs the number of answers behind it.

What you can check on day one

Some of what assistants look for can be checked the moment a page goes live. Of the 41,561 answers about a specific job, 6,407 (15%) said the assistant couldn't find or confirm something about a company. Nearly all came from Claude, which said so in 6,144 of its 14,467 job answers. ChatGPT said it in 241 of 17,275, and Google AI Mode in 22 of 9,819.

That doesn't mean ChatGPT found everything. It means Claude tells the customer what it couldn't check, and the others seldom do. In those answers, the most common missing item was a phone number or other way to reach the company, in 3,851 answers. Whether the company served the customer's town came up in 755. You don't need to wait for any search tool to see whether your own page shows those two things in plain text.

A results timeline you can actually keep

Here is a schedule built around checks you control. Each step has a date for looking, not a promise about what you will find.

1. Before you change anything, write down where you stand

• Write the questions your customers ask, three or four for each job you want more of, naming your towns. Ask each one in ChatGPT, Claude and Google AI Mode, in a new conversation, on several days. Count the share of answers that name you, not your place in the list ⁹.
• Write down last month's calls and form requests from your website, with the number of visits behind them.
• Note your Business Profile calls, website clicks and direction requests, and your clicks in Google Search Console.
• Pull the same months from last year if you have them. That shows your normal seasonal swing.

2. The day the work goes live, inspect it as a customer would

• Open each changed page on your phone. Check that the job, the towns you serve and the phone number are in the page's text, not only in an image.
• Call the number from the page. Send yourself a test request through the form, and confirm someone receives it.
• In Google Search Console, run a live test of the page's address. It checks the page as it is now for problems that would stop Google indexing it ¹⁰.
• Ask whoever runs your site to confirm that robots.txt doesn't block OpenAI's search crawler, because blocked sites aren't shown in ChatGPT search answers ⁶. Anthropic says blocking its search crawler may reduce your visibility in Claude's results ¹¹.
• Write down the date and exactly what changed.

3. In the first days, ask once and wait

Request indexing for the changed pages once, or submit a sitemap, the file that lists your pages for Google. Repeating the request won't speed it up ². Check that your Business Profile edits have gone live, since a few take up to 30 days to review ⁵. If you unblocked OpenAI's crawler, allow about a day before expecting ChatGPT to read the site ⁶.

4. After a few weeks, check discovery

Look up the page in Search Console again to see whether Google has indexed the new version. Crawling alone can take days to weeks ². Then start asking your question list again, on several days. Google suggests waiting a few weeks before judging whether a change helped ¹. Treat the first few weeks of answers as a reading, not a verdict.

5. Every month, record counts with what they're out of

• AI answers: "named in 9 of 40 answers", for each assistant separately.
• Google: clicks in the Search Console Performance report. Clicks from AI Overviews and AI Mode are counted in your overall Google search traffic there ⁴. Use its weekly or monthly view, which smooths out daily swings such as weekends and holidays ¹².
• Business Profile: calls, website clicks and direction requests. Google updates the searches figure at the start of each month, and it can take up to five days to appear ¹³.
• Customers: inquiries and booked jobs, and how each new customer says they found you.

6. Compare like with like

• Compare a month with the same month last year, not just the month before, so the season doesn't fool you.
• If you changed some jobs or towns and not others, compare the two groups. If both rise together, the change probably came from outside, such as the season or an assistant update.
• Compare shares from about the same number of answers. A busier month of checking makes raw counts look bigger.

7. Write down what you can't conclude yet

Small businesses rarely get enough calls for quick answers. Say your website brings about five calls or form requests a month. By chance alone, a month could bring anywhere from 1 to 10, with nothing about your business changing. To be fairly sure your inquiries had doubled, you would need about 5 months of records before and 5 after. To confirm a 50% rise would take about 16 months on each side.

That is not a reason to give up. It is a reason to keep a short monthly note: what changed and when, the counts, and what you can't tell yet. For example: "New water heater page live March 3. Named in 6 of 30 answers in April, up from 4 of 30 in February. Too few to tell. Calls 7, up from 5, but ads also started March 10." A note like that stops one lucky month from deciding whether you keep a provider.

8. Ask a provider for dates for the work, not for results

Google suggests asking anyone you hire for SEO what results they expect to see, and in what timeframe ¹⁴. It also says that if they guarantee first place in search results, you should find someone else ¹⁴. A trustworthy answer is a dated list of work you can check yourself, plus how and when results will be measured. Be wary of a promise that you will be named by ChatGPT, or ranked first, by a set date. Nobody outside OpenAI, Anthropic and Google controls that.

Questions owners ask

How long does local SEO take?

There is no fixed timeline. You can check finished work, such as a corrected page or an updated Business Profile, the same day. Google says crawling a changed page can take days to weeks, and it suggests waiting a few weeks before judging a change. Calls depend on the season and your competitors as well, so judge results over several months of records, not one.

How long does it take to show up in ChatGPT or other AI answers?

No one publishes a timeline. OpenAI says a robots.txt fix takes about a day to reach its search systems, but that only lets ChatGPT read your site. After that, answers vary from run to run and drift over weeks. Date each change, then ask the same customer questions on several days over the following weeks and count how often you're named.

How long does it take Google to index a new or updated page?

Google says crawling can take anywhere from a few days to a few weeks after you request it, and asking repeatedly won't speed it up. It doesn't guarantee that any page will be indexed. Use the URL Inspection tool in Google Search Console to test the live page, request indexing once, then check back.

How long do Google Business Profile changes take to show up?

Google says edits usually take up to ten minutes to review, but some take up to 30 days. Check your profile after a day or two to see whether the change is live or still pending. Business Profile performance figures lag too: the searches figure updates at the start of each month and can take a few days to appear.

How do I know if SEO is working when I only get a few calls a month?

Keep raw counts, not percentages, and compare the same months year to year. With a handful of calls, a month can swing a lot by chance. Record the date of each change and anything else that changed, such as ads or the season. Expect to need many months of records before a modest rise is clearly real.

Should I trust an agency that promises results in 30 days?

Be careful. Google tells site owners to find someone else if an SEO guarantees first place in search results. And no one outside OpenAI, Anthropic and Google controls what their assistants name. A trustworthy provider gives dates for work you can check, explains how results will be measured and says what they can't promise.
