SEO checklist

The basics we set up on every site we build or take over, so search engines and AI assistants can find it, read it and tell who is behind it. 0001.dev runs on the same list.

Found and indexed

  • Pages are rendered on the server, so crawlers read the words without running scripts.
  • robots.txt lets search engines and AI assistants in, and names the sitemap.
  • A sitemap lists every public page, and only those.
  • Pages that should stay out of search, such as a thank-you page, carry noindex.
  • Staging and preview addresses are kept out of search.

One address per page

  • Every page names its canonical address.
  • www, older domains and alternate domains send visitors on with a permanent redirect.
  • Trailing and doubled slashes resolve to one form.
  • Addresses from a previous site redirect to their new pages.

Every page

  • A title of its own that says who you are and what the page is.
  • A description of 50 to 160 characters that reads as a whole sentence.
  • One main heading, and the page's language set in its HTML.
  • A text alternative for every picture.
  • Open Graph and X card tags with a share picture, so a shared link looks right.

Who is behind the site

  • Structured data for the organisation: its name and other names, logo, addresses, founding date and social profiles.
  • The founder or key people as people of their own, linked to the organisation.
  • The site's name and alternate names, which Google can show in results.
  • Breadcrumbs, and the right type for each page: about, contact, article or blog post.
  • All of it checked in Google's Rich Results Test.

Words that match searches

  • The company's name, other names, country and founder in the visible text of the home and About pages, not only in tags.
  • A page for each service or product, with its name in the title and the main heading.

Speed and phones

  • Core Web Vitals within Google's thresholds on a phone.
  • Files cached for a long time, with names that change when they do.
  • Pictures sized for the screens they appear on.

AI assistants

  • An llms.txt that says what the company is and where its main pages are.
  • No robots rule that blocks the assistants you want to be cited by.

Google and Bing

  • The domain verified in Google Search Console with a DNS record.
  • The sitemap submitted, and indexing requested for the home and About pages.
  • The site added to Bing Webmaster Tools.
  • A verified Google Business Profile with the right category, the website and a service area. The street address stays hidden unless clients visit it.
  • LinkedIn, Instagram and other profiles link back to the site.

Kept up

  • An automated check of everything above before every release, and again on the live site after it.
  • Search Console's indexing and performance reports reviewed while we look after the site.
