Meta & Head
22.2/25
Title, description, canonical, social tags — what search engines read first.
Canonical URLmedium impactlow effort
No <link rel="canonical"> found
When the same page is reachable at several URLs — tracking parameters, trailing-slash variants, http vs https — search engines may split ranking signals across the duplicates. A canonical tag names the one version that should get all the credit. Add <link rel="canonical" href="https://www.example.com/page/"> to the <head>, pointing at the page's preferred absolute URL. Double-check it's self-referencing on the primary version: a canonical that points at the wrong page can quietly de-index the right one.
Open Graph tagsmedium impactlow effort
Missing Open Graph tags: og:url
Your Open Graph markup is incomplete, so social platforms fall back to guessed text or drop the preview image entirely when this page is shared — a broken card gets far fewer clicks than a complete one. Add the missing og:url tag to <head>. For og:image, use an absolute https:// URL to an image around 1200x630 pixels; relative paths are the usual reason previews break. Re-check with a platform's sharing debugger afterwards, since preview cards are cached.

Content & Structure
17.9/25
Headings, copy depth, images, structured data, internal linking.
Word counthigh impactlow effort
290 words of visible text
Under 300 words, search engines typically classify a page as thin content, and thin pages rarely rank for anything competitive. Decide which query this page should answer, then write substantive copy — aim for 600+ words covering what it is, how it works, common questions, and concrete examples. If the page genuinely has nothing more to say, merge it into a stronger related page with a 301 redirect rather than padding it with filler that helps no one.
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.
