Claude already writes well and reasons well. Give it a real technical SEO auditor and it can check any page, crawl a whole site, tell you what to fix first and show you what changed after you fixed it. Nothing to install: connect once and ask.
Free for 14 days the first time you connect. No card.
Works on claude.ai in the browser and in the Claude desktop and mobile apps. Takes about a minute.
Go to Black SEO Analyzer in Claude's directory and click Connect. You can also find it in Claude under Settings → Connectors → Browse 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 Claude 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: "Check https://example.com/contact for SEO problems." Claude picks the right tool, runs it and explains the result. Results stay in your account, so you can come back to them in a later chat.
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
Check https://demo.blackseoanalyzer.com/contact for SEO problems.
Claude 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 and tell me what to fix first.
Claude 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 Claude 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.
This is where Claude earns its keep. One template usually produces hundreds of rows of the same issue; Claude 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?
Claude 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.
Claude 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?
Claude 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 Claude 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 with a bseoa license. Local use is covered by the free 14-day trial too.
Download the bundle for your platform, double-click it, and Claude Desktop installs it and asks for your license key.
With the bseoa CLI installed, store your key and add the server:
bseoa license store <key> claude mcp add bseoa -s user -- bseoa mcp
Or install the bseoa skill, which teaches Claude Code the CLI and installs it for you.
Cursor, VS Code and other MCP hosts are on the connector page.
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 Claude.
Crawls stop at 2,000 pages each. Single-page checks and search previews never count. When the trial ends, ask Claude for account status and it gives you the checkout link for the plan that fits your account, or pick one on the pricing page.
Connect once, then ask. 14 days free, no card.
