ChatGPT can explain SEO all day; what it couldn't do was look at your site. Black SEO Analyzer gives it a real technical SEO auditor: check any page, crawl a whole site, rank the fixes and show what changed after you fixed them. Nothing to install: add it once and ask.
Free for 14 days the first time you connect. No card.
Works in ChatGPT on the web and in the desktop and mobile apps. Takes about a minute.
Go to Black SEO Analyzer in ChatGPT and add it. You can also search for it under Settings → Apps & Connectors.
A Black SEO Analyzer page opens. Enter your email; we send a 6-digit code and a sign-in link. Use either one, then click Allow so ChatGPT can run audits in your account. New here? That same sign-in starts your free 14-day trial.
Start a new chat and ask in plain words: "Use Black SEO Analyzer to check https://example.com/contact for SEO problems." Naming it the first time makes sure ChatGPT reaches for it. Results stay in your account for later chats.
Already own a bseoa license? Sign in with the email you bought it with, or choose I have a license key on the sign-in page. The hosted add-on for license holders is $15 a month.
These work as written. demo.blackseoanalyzer.com is a made-up bakery site we keep with known problems, so you can try everything before pointing it at your own site.
Check one page in seconds
Use Black SEO Analyzer to check https://demo.blackseoanalyzer.com/contact for SEO problems.
ChatGPT lists what's wrong with that page, worst first, with how to fix each one. Here it finds the contact page is set to noindex, so search engines leave it out. Single-page checks never count against your page budget.
Audit a site and get a fix list
Audit https://www.blackseoanalyzer.com/ up to 50 pages with Black SEO Analyzer and tell me what to fix first.
ChatGPT starts a crawl, waits for it, then ranks the findings by what they cost you: broken links, redirect chains, missing titles and duplicate descriptions ahead of minor hints. Say a page count or it crawls up to 500.
Turn the findings into work
Group those issues by template and write me a ticket for each group, with the fix and the affected URLs.
One template usually produces hundreds of rows of the same issue; ChatGPT collapses them into a handful of tickets your developer can act on.
Prove the fix worked
Compare my last two crawls of demo.blackseoanalyzer.com. What improved and what got worse?
ChatGPT reports the issues fixed, the new ones and the ones still there. Audit, fix, audit again, and you have a before-and-after you can send to a client.
Preview the search result
How will https://demo.blackseoanalyzer.com/ and /menu look in Google? Rewrite any title that gets cut off.
ChatGPT shows each title and description as a search result would, marks where they'd be truncated, and writes replacements that fit.
Ask what an issue means
What does link.redirect_chain mean and how do I fix it on WordPress?
ChatGPT reads the issue's reference page from our documentation and answers from it, with a link, instead of guessing from a web search.
bseoa reads and reports; it never logs in to your site or changes it. Ask ChatGPT to edit your CMS and it will tell you it can't.
The hosted connector runs crawls on our servers. If you'd rather crawl from your own computer, with JavaScript rendering, external link checks and no page budget, the same eleven tools run locally in Codex CLI with a bseoa license. Local use is covered by the free 14-day trial too.
With the bseoa CLI installed, store your key and add the server:
bseoa license store <key> codex mcp add bseoa -- bseoa mcp
Or install the bseoa skill: unzip it into ~/.agents/skills/ and invoke it with $bseoa. It teaches Codex the CLI and installs it for you.
Starts at your first sign-in. 5,000 crawled pages, results kept 30 days, every tool. No card.
The add-on for anyone who owns a Single or Agency License. 25,000 pages every rolling 30 days, results kept 90 days.
No license needed. Same 25,000 pages and 90-day retention, everything from ChatGPT.
Crawls stop at 2,000 pages each. Single-page checks and search previews never count. When the trial ends, pick a plan on the pricing page and sign in with the same email; ChatGPT itself doesn't handle purchases, so it will point you here rather than offer a checkout.
Add it once, then ask. 14 days free, no card.
