Technical Health

97.84

Whether search engines can fetch, trust, and quickly load the site.

Strengths

  • CrawlabilityStrong

    Crawlers are welcome here: a sitemap points the way, links work, and pages are allowed into the index.

  • SpeedStrong

    Pages load quickly, and the server answers fast.

  • URL and canonical hygieneStrong

    URLs are clean and consistent, each page has one address, and missing pages say so.

Opportunities

Nothing stands out to work on here.

Content Quality

83.00

Whether pages say clearly what they are about, in a form machines can read.

Strengths

  • Titles and descriptionsStrong

    Every page has a clear title and a description of its own, and shares well when linked.

  • Depth and readabilityStrong

    Pages say enough to be useful, in plain language, and stay on the topic their titles promise.

  • HeadingsStrong

    Each page has one main heading, with subheadings in a sensible order beneath it.

Opportunities

  • Images and linksPartial

    Pages link to one another, though some images lack a description and some link text says "read more" rather than where it leads.

Answer Readiness

38.87

Whether content is shaped and marked up so an engine can lift a direct answer.

Strengths

  • Scannable formattingStrong

    Pages open with a short summary and use lists and tables, so an engine can lift the facts without reading everything.

Opportunities

  • Structured dataWeak

    Little structured data is present, so engines have to infer what each page is rather than being told.

  • Question-and-answer shapePartial

    Some headings are questions with an answer beneath them; more of them, each followed by a short direct answer, is what an answer engine lifts.

  • Navigation aidsMissing

    Pages give no sign of where they sit in the site; a breadcrumb trail on interior pages, in text and in markup, is the fix.

AI Visibility

66.40

Whether AI systems can reach, read, and confidently identify the site.

Strengths

  • AI accessStrong

    AI crawlers are allowed in, and pages may be quoted in AI answers.

Opportunities

  • IdentityWeak

    Little here says who is behind the site, in the markup or on the pages themselves.

  • Authorship and sourcingWeak

    Articles rarely say who wrote them or when, and pages rarely link out to sources, which gives an AI little reason to trust them.

  • Readable without JavaScriptPartial

    Most content is readable without running scripts, but some pages arrive thin, or the content is not clearly marked out from the furniture around it.

Authority

87.39

Whether the wider web vouches for the site.

Strengths

  • BacklinksStrong

    Plenty of other sites link here, including ones that matter.

  • TrafficStrong

    The site has a large audience.

  • Domain historyStrong

    The domain has a long history, and history counts.

Opportunities

Nothing here to work on. The points left are the ones only the web's largest sites earn.

Scores reflect what IndexBot could read from anthropic.com's available pages on .

IndexBot

IndexBot is the crawler behind SEO Leaderboard. It visits a website only when someone submits that domain, reads it the way a search engine would, and leaves.

What it does

  • Fetches the homepage, robots.txt, the sitemap, and up to 24 more pages, at most four at a time.
  • Reads raw HTML only. It runs no JavaScript and loads no images, fonts, or scripts.
  • Visits a domain at most once every 24 hours, however many people submit it.
  • Stores what it measured, never full copies of pages.

How it identifies itself

Mozilla/5.0 (compatible; IndexBot/1.0; +https://seoleaderboard.com/bot)

How to let it in

Bot protection often turns IndexBot away before it reads anything, and the domain then cannot be scored. If you run the site, allow the User-Agent IndexBot. In Cloudflare that is a WAF skip rule; most other tools have the same idea under a different name.

(http.user_agent contains "IndexBot")

IndexBot has no fixed IP range to allow instead, so the User-Agent is the only thing to match on. It never tries to disguise itself as a browser, and the limits above are the whole of what it asks for.

How to keep it out

IndexBot obeys robots.txt. Add this and it will not read your site, and your domain cannot be scored.

User-agent: IndexBot
Disallow: /
