# Site Architecture — Technical SEO

Crawling, indexing, rendering, performance and everything the bots must do to find and understand your site.

Underlying category: [Technical SEO](https://seo-mcp.io/c/technical-seo) (50 tips).

- [Fix internal links to 404 pages](https://seo-mcp.io/t/fix-internal-links-to-404-pages) — Internal links to 404 pages waste crawl budget and strand visitors. Crawl the site, list every target that returns 404 or 410, and trace the linking pages. Then either update the link to a live URL or add a redirect when a real replacement exists. Re-crawl to confirm zero broken internal links.
- [Fix mixed content on HTTPS pages](https://seo-mcp.io/t/fix-mixed-content-on-https-pages) — Mixed content is any http:// resource loaded by an https:// page. Browsers block active mixed content such as scripts and styles, and warn or auto-upgrade passive images. Find it in the console and in crawl output, then serve every subresource over HTTPS, including third-party embeds.
- [Handle faceted navigation with canonicals](https://seo-mcp.io/t/handle-faceted-navigation-with-canonicals) — Facets multiply URLs into thousands of near-duplicates. Decide which combinations deserve indexing, give those unique titles and copy with self-canonicals, and canonicalize the remainder to the closest indexable parent. Block infinite parameter spaces and monitor crawl stats for facet-heavy URLs.
- [Add pagination handling for archives](https://seo-mcp.io/t/add-pagination-handling-for-archives) — Paginated archives need crawlable anchor links, a self-referencing canonical on each page and a clear stop at the last page. rel=next and rel=prev are no longer used for indexing. Ensure new items get internal links and that page two is not blocked or redirected to page one.
- [Serve security headers](https://seo-mcp.io/t/serve-security-headers) — Security headers reduce injection, clickjacking and downgrade risk. Send HSTS with a long max-age, a Content-Security-Policy in report-only mode first, X-Content-Type-Options nosniff, a Referrer-Policy and frame-ancestors. Verify with curl headers on the production host before you enforce the policy.
- [Add a meta viewport tag](https://seo-mcp.io/t/add-a-meta-viewport-tag) — The viewport meta tag tells mobile browsers to use the device width. Without it, pages render at a virtual desktop width and text becomes unreadable. Add width=device-width, initial-scale=1, do not disable zoom, and verify the tag is in the server response.
- [Programmatic SEO for Niche Job Boards: Templated Pages at Scale](https://seo-mcp.io/t/programmatic-seo-for-niche-job-boards-templated-pages-at) — Generate templated listing pages from structured job data so every role-and-location combination has a crawlable URL, then invest in the technical SEO underneath it. Unique titles built from template fields, internal links from hub pages, fast list and detail templates and clean indexation are what turn the template set into rankings. The tactic transfers to any niche with repeating structured records; without that technical layer the generated pages stay thin.
