What is the Index Quotient?

How ready a website is to be found by search engines, answer engines, and AI, from 0.00 to 100.00. The average of five Pillar Scores.

Anyone can submit any public domain. Every site is read the same way, once a day at most, by a crawler that obeys robots.txt.

Technical Health
Whether search engines can fetch, trust, and quickly load the site.
Content Quality
Whether pages say clearly what they are about, in a form machines can read.
Answer Readiness
Whether content is shaped and marked up so an engine can lift a direct answer.
AI Visibility
Whether AI systems can reach, read, and confidently identify the site.
Authority
Whether the wider web vouches for the site.

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: /
