What are the most common SEO tools?

The tools that come up most often in any real conversation are Google Search Console for free performance data, Ahrefs and Semrush for keyword research and competitor analysis, and Screaming Frog for detailed technical crawls.

On the content side specifically, Yoast and Rank Math are the most common on-page plugins for WordPress in particular, checking basics like title length and readability as you actually write the page.

Most real SEO workflows end up stitching two or three of these tools together, since no single tool on this whole list covers research, writing, and publishing all together in one single place.

That stitching problem is exactly what automatic SEO software is built to remove.
