On-page SEO audit
iana.org
https://www.iana.org/help/example-domainsiana.org scores 85 out of 100 for on-page SEO health - broadly healthy with a few fixes outstanding. We evaluated 53 of 66 checks on this page and found 3 critical issues, 13 warnings and 37 checks that passed cleanly. The most significant problem is meta description present: Without one, search engines write your snippet for you from whatever text they find. Close behind it, canonical tag present needs attention - Add <link rel="canonical" href="…"> pointing at the preferred URL. Structured data is the weakest area at 50/100, covering schema presence, validity, type appropriateness, open graph, twitter cards. The page currently uses the title "Example Domains" (15 characters) and no meta description at all. We counted 188 words of body content, 27 internal links, 4 external links and 1 image, under the heading "Example Domains". Working through the 16 outstanding items below would move iana.org towards a healthy score.
