Every SEO tool your blog needs.
All free.

Yes, but not an expensive one. As a blogger, the core SEO tasks you actually need to do are: audit your posts for on-page issues, write good meta titles and descriptions, compress your images for page speed, and check your domain authority over time. All of these are available free on SEO Site Checker. You only need paid tools like Semrush or Ahrefs if you're doing large-scale keyword research or backlink campaigns across multiple sites.

Start with an audit: run your blog URL through SEO Site Checker's Website SEO Score Checker to find the exact issues hurting your rankings. The most common fixes for bloggers are: writing unique meta descriptions for every post (use the Meta Tag Analyzer to check and fix these), compressing all images before uploading (use the Image Compressor), fixing heading structure so each post has one H1 and logical H2s, and adding internal links between related posts.

Completely free. There are no paid plans, no premium features, and no credit card ever required. You can use every tool as a guest without creating an account. Creating a free account (no cost, no card) unlocks full detailed reports, PDF downloads, and up to 100 tool uses per day. The platform is funded by non-intrusive ads, not by charging users.

For a new blogger, the Website SEO Score Checker is the single most valuable starting point. It tells you everything that's wrong with your blog's on-page SEO in one scan and gives you a prioritised list of fixes. Once you've worked through those fixes, the Meta Tag Analyzer becomes your most-used tool: run it before publishing every new post to make sure your title and description are properly optimised.

Most bloggers upload images at full camera or phone resolution, often 3-6 MB per image without compressing them first. Page load time is a Google ranking factor, and large images are the most common cause of slow blogs. A 3 MB image can typically be compressed to under 300 KB with no visible quality difference using SEO Site Checker's Image Compressor. If your blog has 20 posts with 3 images each, this single fix can dramatically improve your site speed scores.

The meta title is the clickable headline that appears in Google search results, it's one of the most important on-page SEO factors. The meta description is the 2-3 line summary that appears below it. Neither directly affects your keyword ranking, but a well-written meta description improves your click-through rate, which indirectly helps your rankings. SEO Site Checker's Meta Tag Analyzer checks both for length, keyword inclusion, and completeness and lets you preview exactly how your post will look in Google.
