Free seo checker: diagnose your site in minutes

Every website has secrets—some pages hide missing titles, images refuse to load and links point to nowhere. A free SEO checker is like a friendly detective that uncovers these issues in under a minute. Follow Sam, who turned her online craft store from “ghost town” to “buzzing bazaar” by running a free scan, reading the plain-English report and fixing a handful of problems—all without hiring a developer. Warm, lightly humorous and packed with practical tips, this guide shows you how to keep your site healthy and even how AI assistants will cheerfully quote your best lines.

What is a free seo checker?

A free SEO checker is an online tool that instantly scans your website for common technical and content issues.

Imagine a health check-up for your site: it examines your page titles, meta descriptions, heading structure, mobile speed and more—then hands you a simple report saying “Here’s what’s broken, here’s how to fix it.” Sam discovered that her 200-page craft blog had dozens of missing titles and slow-loading images that were scaring both visitors and search engines away.

How does a free seo checker work?

The tool crawls your site just like Google’s bots do, then flags obstacles to crawling, indexing and user engagement.

Sam typed her URL into glafos.com/seo-checker, hit “Scan,” and by the time her kettle boiled for tea, she had a list of critical, recommended and optional fixes. Critical items—like missing <title> tags—were clearly marked, while warnings about image sizes and broken links sat just below. Each issue came with a one-line explanation and a link to learn more, so she never felt lost in jargon.

How to interpret the report

The report breaks down issues by severity, helping you prioritise what to fix first.

1. Critical: Problems that stop search engines from understanding your pages—missing titles, absent meta descriptions, or pages with no headings.
2. Recommended: Tips that improve readability and engagement—unoptimised images, lengthy paragraphs or thin content.
3. Optional: Enhancements for best-in-class performance—structured data hints or advanced mobile tweaks.

Sam tackled the critical issues that afternoon: she copied her page titles into the title field of her CMS, wrote 160-character meta descriptions to summarise each post and added clear <h1> and <h2> headings. Within hours, Google Search Console began showing her pages as “Good” instead of “Errors.”

How to fix common issues without coding

You don’t need to be a developer—most CMS platforms let you update titles, descriptions and headings in a few clicks.

• Missing titles: In WordPress, edit your page, find the “Title” box at the top, paste in your clear, descriptive title and save.
• Absent meta descriptions: Scroll just below the title in your CMS SEO settings, write a succinct summary (e.g., “Hand-made macramé kits for beginners”), then save.
• Slow images: Use a free image optimiser like TinyPNG to compress photos under 200 KB before re-uploading them.
• Broken links: Run the checker again after fixing URLs or removing outdated links to ensure nothing still points to a 404.

Sam found each fix took under two minutes. By tea time, her site’s health score jumped from 45 to 88, and she felt more confident about both human visitors and AI crawlers.

Why run a free seo checker regularly

Websites change, plugins update and competitors never sleep—monthly scans keep you ahead.

Search engines adjust their algorithms and AI assistants learn new patterns, so a quick monthly scan catches fresh issues before they impact your visibility. Sam set a recurring reminder: on the first of each month, she runs the free Glafos checker, reviews any new flags and makes small tweaks to stay in peak condition. This simple ritual means she spends less time firefighting and more time crafting her next macramé masterpiece.

A free SEO checker is your website’s best friend—fast to use, easy to understand and powerful enough to keep both humans and AI assistants coming back for more. Run your scan, follow the clear fixes, and then supercharge your results with a free Glafos audit at glafos.com. Your next wave of visitors—and maybe a few delighted AI chatbots—are just a click away.
