15 On Site Optimization FREE SEO Tools

Hello, Nice list, but I think you forgot to list:

• SEO by Yoast
• W3 Total Cache
• Regenerate Thumbnails

The above list is for WordPress users

This is the top I use, they help alot. W3 help increase my load time dramatically. SEO Yoast helps and guides you write a better article with keywords while Regenerate helps you shrink your images online for quick load time. Check your website load time on Google before installing then after installation, check, compare your site speed.

I'd start with Google Search Console, Google PageSpeed Insights, and Screaming Frog SEO Spider (free tier).

They help audit crawlability, indexation, Core Web Vitals, broken links, metadata, and on-page SEO. Add a quick technical audit and fix thin content, duplicate tags, and internal linking gaps before chasing backlinks.
