Crawlers are welcome here: a sitemap points the way, links work, and pages are allowed into the index.

Pages load quickly, and the server answers fast.

Every visit is encrypted, and the headers that keep it that way are in place.

URLs are mostly in order; what remains is giving every page one settled address and making missing pages answer as missing.

Every page has a clear title and a description of its own, and shares well when linked.

Images are described in text, and pages link to each other with links that say where they go.

Each page has one main heading, with subheadings in a sensible order beneath it.

Pages have substance, but many stop short, drift from their titles, or read harder than they need to.

Pages open with a short summary and use lists and tables, so an engine can lift the facts without reading everything.

Interior pages show where they sit in the site, and say so in a way engines can read.

Structured data is partly there: not on every page, not always complete, and not always the types that earn rich results.

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 crawlers are allowed in, and pages may be quoted in AI answers.

It is clear who is behind this site, on its pages, in its markup, and in the public record.

Articles carry an author and a date, and the content points to its sources.

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.

Either a feed or sitemap dates are in place, not both; machines that watch for new content want both.

Plenty of other sites link here, including ones that matter.

The site has a large audience.

The domain has a long history, and history counts.

The site points to some of its social profiles; linking the rest of its major ones rounds this out.
