Title, description, canonical, social tags — what search engines read first.

Everything we check in this category passed.

Headings, copy depth, images, structured data, internal linking.

• Internal linkingmedium impactmedium effort

  0 internal, 4 external links

  Search engines discover and rank your pages by following internal links; a page with none is a dead end for crawlers and visitors alike. Add contextual links to related pages on your own site — navigation, related-content sections, and in-body links all count. Aim for at least a handful of relevant internal links per page.

• Structured data (JSON-LD)medium impactmedium effort

  No JSON-LD structured data blocks found

  Structured data makes your listing eligible for rich results — star ratings, FAQs, breadcrumbs, product prices — which occupy more space on the results page and draw more clicks than plain blue links. Add a <script type="application/ld+json"> block with a schema.org type that matches the page: Organization or WebSite for a homepage, Article for posts, Product for product pages. Only mark up content actually visible on the page — markup for invisible content violates Google's guidelines and can earn a manual action.

HTTPS, redirects, robots, sitemap, speed, crawlability.

• robots.txt present and permissivemedium impactlow effort

  no robots.txt found

  Without a robots.txt, crawlers assume everything is allowed — not fatal, but you lose the ability to keep them out of low-value areas (internal search results, carts, admin paths) and the standard place to advertise your sitemap. Create a plain-text robots.txt at the site root with at least a "User-agent: *" line and "Sitemap: https://www.example.com/sitemap.xml". Don't use it to hide sensitive URLs, though — the file is public, and disallowing a page doesn't remove it from the index; use noindex or authentication for that.

• XML sitemap availablemedium impactlow effort

  no sitemap.xml found

  Without an XML sitemap, search engines discover pages only by following links, so new, deep, or weakly linked pages get found slowly or not at all. Generate one at /sitemap.xml — most frameworks and CMSs have a generator built in or as a plugin — listing every canonical, indexable URL, then add "Sitemap: https://www.example.com/sitemap.xml" to robots.txt and submit it in Google Search Console. Keep it clean: listing redirected, noindexed, or 404 URLs erodes crawler trust in the whole file.

• Response compression enabledlow impactlow effort

  no content-encoding header

  This HTML is served uncompressed, so every visitor downloads far more bytes than necessary — text compresses extremely well, and the savings directly speed up first render on slow connections. Enable Brotli or gzip on your server or CDN: in nginx it's "gzip on;" (or the brotli module), in Apache it's mod_deflate via .htaccess, and on most CDNs it's a single toggle. Make sure compression covers all text types (HTML, CSS, JS, JSON, SVG), but skip already-compressed images — recompressing them wastes CPU for no gain.
