Search Engine Optimization 


Basically, SEMrush tools can help in SEO, but the specific tools for search engine optimization available are the SEO Writing Assistant tool and the On-Page SEO checker.

The SEO writing assistant tool works for content optimization. It analyzes your content to detect its SEO-friendliness and plagiarism count. It also checks for voice tone, word count, and readability.

The On-Page SEO checker analyzes your site’s general SEO health with insight into technical ideas, strategy ideas, SERP features, semantic ideas, etc. That way, you can check the SEO health of your entire site or specific pages.
