Technical Health

96.85

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

73.63

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

Strengths

  • Images and linksStrong

    Images are described in text, and pages link to each other with links that say where they go.

  • FreshnessStrong

    Something here was published or updated recently, and the site says when.

  • LanguageStrong

    The page language is declared and matches what is on the page.

Opportunities

  • Depth and readabilityPartial

    Pages have substance, but many stop short, drift from their titles, or read harder than they need to.

  • Titles and descriptionsPartial

    Titles are mostly in place; descriptions and link previews are patchier, and each page wants ones of its own.

  • HeadingsPartial

    Headings are there, but not always one main heading per page or a tidy order of levels beneath it.

Answer Readiness

53.45

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.

  • Navigation aidsStrong

    Interior pages show where they sit in the site, and say so in a way engines can read.

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.

AI Visibility

65.80

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.

  • FeedsStrong

    The site offers a feed, and its sitemap says when pages last changed.

Opportunities

  • IdentityPartial

    Who is behind the site is partly clear; an About page, a Contact page, and markup naming the organization would let machines say so with confidence.

  • 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.

  • 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.

Authority

86.51

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 archives.gov'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: /
