Free SEO Checker - Instantly Audit Any Website's On-Page SEO

The tool grades meta descriptions on length, not just presence. Under 100 characters = Fail (Google truncates short descriptions in SERPs and they provide weaker relevance signals). Between 100-160 characters = Pass (full 15 points). Between 161-180 characters = Warning (slightly long, Google may trim it). Over 180 characters = Fail. The result card shows your exact character count and the full description text, so you can see precisely how much to add or trim.

This checker validates self-referencing, not just presence. A canonical tag that points to a different URL - such as www vs non-www, a trailing slash mismatch, or a completely different page - earns a Warning (5/10 pts) instead of a Pass (10/10 pts). This is intentional: a canonical pointing elsewhere tells Google to attribute ranking signals to that other URL, which may be a deliberate redirect consolidation or an accidental misconfiguration. The result card shows the full canonical href so you can confirm whether it matches the URL you audited.

Start with the Issues list at the bottom of your results - every failed and warned check is listed there, sorted from highest point weight to lowest. The three checks worth 15 points each (Title Tag, Meta Description, H1) should be your first priority: a missing or too-short title and meta description alone can cost you 30 points. After those, check for missing image alt text (10 pts), a missing or mis-configured canonical tag (10 pts), and absent Open Graph tags (10 pts). Fix one issue at a time, hit Re-Test, and watch your score climb. Most pages can move from below 50 to above 75 by fixing just 3-4 of the flagged items.

Extremely serious. A noindex directive in your robots meta tag (e.g. `<meta name="robots" content="noindex">`) instructs Google and every compliant crawler to exclude the page from search results entirely. It doesn't matter how good your content, backlinks, or other SEO is - a noindexed page will not appear in Google. The check flags this as a Fail (0/5 pts) and places it at the top of your Issues list. Fix it by changing the directive to `content="index, follow"` or removing the tag altogether, then click Re-Test to confirm the issue is resolved.

The 10 scored checks each carry a point weight (5-15 pts) that directly form your SEO score out of 100. These are the HTML factors Google most clearly uses to crawl, understand, and rank pages. The 10 bonus checks - Twitter Card, viewport meta, BreadcrumbList schema, HTML lang, favicon, accessible links, accessible buttons, labelled inputs, raw mailto links, and broken anchor targets - are informational quality signals. They display as a separate pass/fail grid and do not add to or subtract from your score, so they won't inflate a bad score or penalise a good one.

An invalid href is a link where the href attribute doesn't follow a recognisable URL format. For example, `href="about"` instead of `href="/about"`, or `href="contact.html"` without a leading slash. These work inconsistently depending on the page's URL path and can confuse crawlers. The check detects any href that doesn't start with http://, https://, /, #, mailto:, tel:, or javascript: - and drops the Links score to a Warning (3/5 pts). The result card shows the first offending href so you know exactly which link to fix.

Yes - the tool audits any publicly accessible URL regardless of what platform or CMS built it. WordPress, Shopify, Webflow, Wix, Squarespace, custom HTML/CSS sites, and server-side rendered Next.js or Nuxt apps all work perfectly. If a page is accessible to a regular visitor without logging in, this tool can audit it. That also means you can audit competitor pages built on any platform - just paste their URL and run the audit.

After an audit completes, clicking Share generates a URL in the format `https://nocodevista.com/tools/seo-checker?url=https://yoursite.com/page`. On mobile it opens the native share sheet; on desktop it copies the link to your clipboard. When anyone opens that link - a client, a colleague, or a stakeholder - the tool automatically audits the same URL and shows them a fresh live report. They don't need an account. The results they see reflect the current state of the page at the moment they open the link, not a cached snapshot.
