A Collection of Free SEO Tools and Resources

SEO tools investigate the potential of web pages for high placement on search engine ranking pages. They provide information on backlinks and keywords as well as insights into SEO competition on the Internet. SEO works by optimizing your site for the search engine that you want to rank for, whether it’s Google, Bing, Amazon or YouTube. In most cases, when people think ‘search engine optimization’, they think ‘Google SEO’.

Many SEO Tools highlight issues or problems with your website. This information can be key in your website ranking and will need to be fixed quickly.

There are three types of SEO you need for a well-rounded organic search strategy: on-page SEO, technical SEO, and off-page SEO. By breaking down your strategy and thinking about SEO as these three categories, it will be much easier to organize and execute your optimization plans.
