epfl.ch
Ranked #157 of 300 on the Leaderboard. Analyzed .
Index Quotient
72.55
Technical Health
90.18Whether 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.
- URL and canonical hygieneStrong
URLs are clean and consistent, each page has one address, and missing pages say so.
- Safe to visitStrong
Nothing marks this site as unsafe to visit.
Opportunities
- SpeedPartial
Pages load reasonably but not quickly, so visitors wait longer than they need to.
- 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
76.64Whether pages say clearly what they are about, in a form machines can read.
Strengths
- Depth and readabilityStrong
Pages say enough to be useful, in plain language, and stay on the topic their titles promise.
- Images and linksStrong
Images are described in text, and pages link to each other with links that say where they go.
- HeadingsStrong
Each page has one main heading, with subheadings in a sensible order beneath it.
Opportunities
- Titles and descriptionsPartial
Titles are mostly in place; descriptions and link previews are patchier, and each page wants ones of its own.
Answer Readiness
43.32Whether 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 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.
AI Visibility
70.28Whether 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
- 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.
- 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
82.31Whether 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.
