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.

• Heading hierarchylow impactlow effort

  Heading level jumps from h2 ("How to Use Leptozan") to h4 ("Start Your Day with Leptozan")

  Headings form the page's outline; when levels jump (h2 straight to h4), search engines and screen readers get a broken table of contents and the relationship between sections turns ambiguous. Fix the jump by stepping down one level at a time — promote the deeper heading, or add the missing intermediate level. The usual cause is choosing heading tags for their default font size; set sizes in CSS instead and let the tags reflect actual document structure.

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

• XML sitemap availablemedium impactlow effort

  sitemap.xml exists but is not valid XML

  Your sitemap exists but isn't valid XML, so search engines reject the whole file and you get none of its discovery benefit — worse than having no sitemap, because you probably believe it's working. Regenerate it with your framework's built-in generator or a sitemap library rather than hand-editing; unescaped ampersands in URLs (& instead of &) are the most common breakage. Validate before deploying, and check the Sitemaps report in Google Search Console afterwards — it surfaces parse errors explicitly.

• HTTP redirects to HTTPSmedium impactlow effort

  http:// version serves content without redirecting

  Your http:// URLs serve content instead of redirecting, so search engines can crawl and index two parallel copies of every page and split ranking signals between them. Add a permanent 301 redirect from http to https at the server or CDN level — in nginx, "return 301 https://$host$request_uri;" in the port-80 server block; in Apache, a RewriteRule in .htaccess; on Cloudflare, enable "Always Use HTTPS". Use a 301, not a 302 — temporary redirects don't consolidate ranking signals — and preserve the full path in the redirect target.

• 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.

• Missing pages return 404low impactlow effort

  missing paths return a non-404 status (soft 404)

  URLs that don't exist on your site return a success status instead of 404 — search engines call these soft 404s, keep recrawling them, and may index the useless placeholder pages, wasting crawl budget that should go to real content. Configure your server or framework to return an actual 404 status (or 410 for permanently removed content) along with your error page. The classic mistake is serving a friendly "page not found" template with a 200 status — crawlers ignore the visible message; only the status code counts.
