Free Website SEO Checker Online - 70+ Checks in Seconds

Why You Need a Website SEO Checker

Search engine optimization is the backbone of online visibility. Without it, even the best-designed website can remain invisible to potential visitors. An SEO checker gives you a clear, data-driven picture of where your site stands and what you can do to improve.

Many website owners assume their site is "fine" because it loads and looks good. But search engines evaluate dozens of technical signals - from meta tags and heading structure to structured data and image alt text. Missing even a few of these can push your pages down in search results.

What Does a Free SEO Check Cover?

A comprehensive SEO audit goes far beyond just checking your page title. Here is what Website Grader analyzes when you run a free scan:

Meta Tags and Title Optimization

Your page title should be between 50 and 60 characters, and your meta description between 150 and 160 characters. These are the first things users see in search results. Website Grader checks both length and presence, flagging pages that are missing or have poorly optimized tags.

Heading Structure

Search engines rely on headings (H1 through H6) to understand page hierarchy. Your page should have exactly one H1 tag that clearly describes the content. Multiple H1 tags or skipped heading levels confuse crawlers and hurt rankings.

Image Alt Text Coverage

Images without alt attributes are invisible to search engines and inaccessible to screen readers. Website Grader checks that at least 90% of your images include descriptive alt text - a quick win that many sites overlook.

Structured Data and Schema Markup

Rich snippets in search results come from structured data. Website Grader verifies whether your pages include JSON-LD or other schema markup, helping you earn enhanced search listings that drive more clicks.

Beyond SEO: The Full Picture

SEO does not exist in isolation. Site speed, mobile usability, security, and accessibility all affect your search rankings. Google has confirmed that Core Web Vitals, HTTPS, and mobile-friendliness are ranking factors.

That is why Website Grader checks 70+ signals across six categories: SEO, Performance, Mobile, Security, Accessibility, and Content. Each category receives its own score, and the overall grade is a weighted average that reflects real search engine priorities.

How Scoring Works

Your overall score is calculated as: SEO (25%) + Performance (25%) + Mobile (15%) + Security (15%) + Accessibility (10%) + Content (10%). This weighting mirrors how search engines prioritize different aspects of your site.

How to Use the Results

After running a scan, focus on the critical issues first - these have the biggest impact on your rankings. Common quick wins include adding missing meta descriptions, fixing broken links, enabling HTTPS, and compressing images.

For a deeper analysis, the Pro plan unlocks every check with detailed fix recommendations, so you know exactly what to change and why.
