esa.int
Ranked #251 of 300 on the Leaderboard. Analyzed .
Index Quotient
64.56
Technical Health
79.75Whether search engines can fetch, trust, and quickly load the site.
Strengths
- SpeedStrong
Pages load quickly, and the server answers fast.
- Safe to visitStrong
Nothing marks this site as unsafe to visit.
Opportunities
- CrawlabilityPartial
Crawlers can get in, but not everything helps them along: a complete sitemap, working links and pages that are allowed into the index are what to check.
- URL and canonical hygieneWeak
URLs are working against the site: pages answer at more than one address, and missing pages do not say they are missing.
- Secure connectionPartial
The connection is encrypted but not fully hardened: steering every visit onto it and sending the standard security headers would finish the job.
Content Quality
66.94Whether 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.
- 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
34.27Whether 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 dataMissing
Pages carry no structured data, so nothing tells an engine what each one is; marking up the page type, and the site's name, is the first step here.
- 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
57.72Whether 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.
- Authorship and sourcingStrong
Articles carry an author and a date, and the content points to its sources.
Opportunities
- Readable without JavaScriptWeak
Much of the content only appears once scripts run, so a crawler that reads the raw page finds little.
- IdentityWeak
Little here says who is behind the site, in the markup or on the pages themselves.
- FeedsMissing
There is no feed and the sitemap carries no dates, so nothing tells a machine when something new appears; a feed is a small addition.
Authority
84.12Whether 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.
