The problem
Most site problems stay hidden until they cost you traffic.
On the first 60 sites Sitewalk audited, the typical site had 20 different kinds of problem.
- 57%had pages with no meta description
- 53%had pages with no canonical URL
- 45%had pages with no structured data
- 45%linked to a page that no longer exists
Counted per site, not per page, across 60 different sites audited up to 10 November 2026 (audits of 10 pages or more, one audit per site). The owners chose to audit these sites, so this is not a sample of the whole web.
How it works
Three steps. Nothing to learn.
Ask ChatGPT.
Say "Audit yoursite.com for technical SEO problems." The first time, enter the one-time code we email you. There is no password.
Wait while it reads your pages.
Sitewalk reads one page at a time, with a pause between requests so your server stays comfortable. 50 pages usually take a few minutes, 500 pages 20 to 60 minutes. You can close the chat: we email you when it is done.
Read the ranked list.
The worst problem comes first, with a plain fix and example pages. Ask follow-up questions in the same chat.
Then let it keep watching. Ask ChatGPT: "Monitor yoursite.com". Sitewalk checks the site again every month, or every day or week on Pro, and emails you only when something changes.
The report
Worst first, with a count of every problem.
A long list of errors is hard to act on. Sitewalk sorts them by impact and counts each one, so you know where to start.
- 1ERROR
Internal links that lead to a 404 page
Found on 14 pages. Fix: point each link at the live page.
- 2ERROR
Pages blocked by a noindex tag
Found on 3 pages. These cannot appear in Google at all.
- 3ERROR
Pages with no title tag
Found on 9 pages. Fix: add a unique 50 to 60 character title.
Sample data for example.com. Made-up results for illustration only.

Keep asking. Take the report with you.
Ask follow-up questions in the same chat. Download the full report as CSV or PDF to share with your developer.
Try asking
- What should I fix first, and why?
- Which pages have duplicate titles?
- Turn this into a task list for my developer.
- Explain the redirect chains in plain words.
- Write the new meta descriptions for me.

200+ checks
18 groups. Every one spelled out.
Over 200 checks, in 18 groups. Each finding is scored by impact and carries its own plain fix. A check that could not run on your site is left out of the report and is never shown as passed.
See all 18 check groups
Response codes
Whether pages open without errors, are not caught in redirect chains or loops, and come back quickly, at a sensible size and compressed.
Titles and descriptions
Whether every page has a title and a meta description, whether they are a sensible length and not repeated, and whether any title is a placeholder.
Headings and content
Whether each page has a main heading and enough real text, with no copied pages and no leftover placeholder text.
Indexability
Whether search engines are allowed to list each page, whether each page names one correct preferred address (its canonical), and whether any page carries a nofollow tag.
Links
Whether the links on your pages work, have an address a crawler can follow, and have text that says where they lead.
Images
Whether images load, have alt text (a description for people who cannot see them) and a stated width and height, and are not oversized or served insecurely.
URL hygiene
Whether your page addresses are tidy: no spaces, double slashes, underscores, capital letters, session codes or endless filter and calendar pages.
Site structure
How many clicks it takes to reach each page, and whether any page is cut off: nothing links to it, it links nowhere, or it is reached only through one link or through pages set to noindex or nofollow.
International
If your site has versions in other languages, whether the hreflang tags are valid, point back to each other and lead to pages that work.
HTML hygiene
Whether the basics of each page's code are in order: a doctype, one title tag in the head, one head and one body tag, a valid language, zoom allowed on phones, no obsolete tags and few scripts that hold up the page.
Scripts and stylesheets
Whether the script and style files your pages use load without errors, are not oversized and can be saved by browsers for later visits.
Mobile, social and markup
Whether pages have a viewport tag, a declared language and character encoding, the tags that give a shared link a preview, and structured data.
Structured data
Whether the structured data on your pages (schema markup) is valid and complete, is not repeated or in conflict, and uses types Google still shows.
Speed (sampled pages)
A sample of your pages on Google's mobile speed test, plus Google's real-visitor data where Google has it. Shown when the audit runs it.
Security
Whether pages use HTTPS with a valid certificate, the server sends the headers that protect visitors, and nothing loads over HTTP on a secure page.
AI search readiness
Whether your robots.txt and page headers let ChatGPT search and other AI bots in, whether an llms.txt file is there and set out correctly, and whether pages have clear subheadings, article details and content that shows without JavaScript.
Sitemap
Whether a sitemap exists and is listed in robots.txt, lists your pages by their full addresses and only working, indexable ones, and stays within the size limits.
Pages as a browser shows them
For a sample of pages opened in a browser, whether what scripts add or change matches the HTML the page ships with, and whether scripts run without errors. Shown only for audits that open pages in a browser.
The speed group appears when the audit runs it. The browser group appears only for audits that open pages in a browser.

FAQ
Questions
Getting started
Do I need an account?
Yes, a free one. The first time ChatGPT asks, enter the one-time code we email you. There is no password.
Can Sitewalk keep watching my site?
Yes. Ask ChatGPT: "Monitor yoursite.com". On the free plan Sitewalk checks 1 site every month. On Pro it checks up to 3 sites every day, week or month (daily and weekly on sites you verify). You get an email only when something changes, and monitoring checks do not use your monthly audits.
How long does an audit take?
Sitewalk waits at least 1.5 seconds between requests to keep the load on your server light, and it checks each page's images too. In practice 50 pages usually take a few minutes and 500 pages take 20 to 60 minutes. An audit keeps running after you close the chat.
Reports and limits
How many audits and pages do I get?
Free: 5 audits a month. Without signing in, you get 1 audit a day of up to 50 pages. After you sign in with your emailed code, each audit can crawl up to 500 pages on any site.
What does it not check?
Backlinks, keyword rankings and Search Console data. Page speed is a sample, not a score for every page: for up to 3 pages in each audit, Sitewalk asks Google PageSpeed Insights for a mobile Lighthouse score, and adds Google's real-user Core Web Vitals data only where Google has it, which can describe the whole site and not just that page. The report says it is a sample. By default Sitewalk reads the HTML your server sends. On sites you have verified, an audit can also open your home page and the pages that look empty without scripts in a browser. Anywhere else, content that scripts add after the page loads is not read.
Pro and billing
What does Pro cost, and what do I get?
USD 9 a month, billed monthly. You get 50 audits and 20,000 pages a month, pooled across your audits. The same site counts each time it is audited. An audit above 500 pages needs a verified domain.
Can I cancel, and can I get a refund?
Yes, cancel any time. Pro stays on until the end of the period you paid for. If you ask for a refund within 7 days of a payment, a full refund ends Pro at once. Write to contact@sitewalkseo.com.
Which email do I pay with?
The email you use in ChatGPT. That email is your Pro account, so there is nothing to paste.
Privacy and data
Can I audit a site I do not own?
Yes. SitewalkBot reads the site's robots.txt first and identifies itself as SitewalkBot. It uses only ports 80 and 443. The site owner can block it with two lines from the bot page.
What happens to my reports?
They are private to your account and are deleted 12 months after they finish. Your account stays until you ask us to delete it. The privacy notice has the details and how to ask for access or deletion.
