Running an SEO audit takes less than 30 seconds. Here is exactly what happens when you analyze a page.
Paste the full URL of any publicly accessible webpage. The checker works with any platform: WordPress, Shopify, Wix, Squarespace, Next.js, or custom-built sites. You do not need to install anything or create an account.
The tool runs 130+ checks across 8 categories and returns an overall letter grade. Scores above 95 earn an A+, while scores below 45 receive an F. Most websites land between 50 and 75 (C to B range). Each category gets its own sub-score so you can see exactly where your site is strong and where it needs work.
Every audit covers these areas in detail:
Every failed check includes a plain-language explanation of why it matters and the exact code or content fix you need. Missing a meta description? The checker generates one. Missing schema markup? It writes the JSON-LD. You can copy each fix directly into your source code.
Download a detailed PDF report to share with your developer, team, or clients. The report includes every check result, your scores, and all recommended fixes in a format that is easy to hand off and act on.
After analyzing thousands of audits, these are the issues that impact rankings the most.
Google weighs your title tag more heavily than any other on-page element. Keep it under 60 characters, place your primary keyword near the front, and make it compelling enough for humans to click. A well-written title tag alone can move you 10+ positions.
Since March 2024, Interaction to Next Paint (INP) is the official interactivity metric. Unlike FID which only measured the first interaction, INP measures every interaction throughout the page session. Sites with heavy JavaScript frameworks often fail this metric. Aim for under 200ms.
Google's quality raters look for Experience, Expertise, Authoritativeness, and Trustworthiness. For your website, this means: link to an about page, show real author names, display contact information, and have a privacy policy. These trust signals are especially critical for YMYL (Your Money Your Life) topics.
Pages with structured data can earn rich results in Google: star ratings, FAQ dropdowns, how-to steps, and more. These enhanced listings get significantly higher click-through rates than plain blue links. The SEO Checker validates your existing schema and tells you what types to add.
Google has confirmed that accessibility overlaps with SEO best practices. Missing alt text on images means Google cannot understand your visual content. Missing heading hierarchy confuses both screen readers and crawlers. The SEO Checker audits all of these and provides fixes.
It runs a comprehensive audit across 8 categories: technical SEO & performance, meta tags, content quality, structured data, accessibility, E-E-A-T trust signals, mobile optimization, and international SEO. You get a letter grade (A+ to F) with actionable fixes for every issue.

Yes, we estimate Performance, Accessibility, Best Practices, and SEO scores using heuristic analysis of your HTML. Each category includes a confidence level (low/medium/high) since some metrics like Core Web Vitals require browser rendering. For exact scores, run Google Lighthouse directly.
