Technical SEO
The technical structure of a site that affects crawling, indexing and how it appears in search results, separate from writing content and building links.
Project requirement
Make several static domains crawlable and indexable, with a weighted to-do list instead of a flat checklist.
Technical question
Which technical points still matter, and which of them can the build generate instead of a person?
Validation
The build generates the sitemap, robots.txt, canonical links, JSON-LD, llms.txt and https redirects; a link checker checks the built output (internal, cross-site and external links).
Decision
Generate everything that can be derived from the pages and the site configuration; keep titles, descriptions and alt texts as page-level content.
Each domain counts as a separate site; duplicated content across domains needs a canonical link or different content.
Old URLs get a 301 redirect, which keeps their link value and avoids 404 pages.
llms.txt is cheap to generate but is not treated as an SEO tool (state as of 2026-10).
On this bilingual portfolio, every page has hreflang pairs, Person JSON-LD, a sitemap entry and an Open Graph image; detail pages also carry a BreadcrumbList.
