caltech.edu
Ranked #178 of 300 on the Leaderboard. Analyzed .
Index Quotient
71.40
Technical Health
96.84Whether 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
77.10Whether 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.
- HeadingsStrong
Each page has one main heading, with subheadings in a sensible order beneath it.
- FreshnessStrong
Something here was published or updated recently, and the site says when.
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.
Answer Readiness
30.20Whether content is shaped and marked up so an engine can lift a direct answer.
Opportunities
- Question-and-answer shapeMissing
No page poses a question and answers it directly beneath, which is the shape answer engines look for; adding those pages is where this starts.
- Structured dataWeak
Little structured data is present, so engines have to infer what each page is rather than being told.
- Scannable formattingWeak
Pages read as unbroken prose: few lists or tables, and openings that take a while to get to the point.
AI Visibility
70.99Whether 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 sourcingPartial
Some articles say who wrote them and when, and some pages cite sources; the rest should say so too.
- 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
81.86Whether 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.
- Social presenceStrong
The site links to its profiles on the major platforms.
Opportunities
Nothing here to work on. The points left are the ones only the web's largest sites earn.
