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.

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

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

Something here was published or updated recently, and the site says when.

Pages are thin: there is little text for a search engine to judge them on, and what is there does not always match the title.

Titles are mostly in place; descriptions and link previews are patchier, and each page wants ones of its own.

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.

Little structured data is present, so engines have to infer what each page is rather than being told.

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.

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

Much of the content only appears once scripts run, so a crawler that reads the raw page finds little.

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.

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 does not link to any social profile; linking the ones it has connects the site to its wider presence.
