One useful research tool we like is SEMrush, which provides users with top-ranking keywords that drive traffic to their site (and competitor sites), along with the number of searches done for those keywords.

5. SEMrush

SEMrush is a great tool. It allows you to see who is ranking for certain keywords, suggests related keyword phrases and their search volumes and shows the competition for keyword phrases. The tool can also be used to see all valuable keywords for which a competitor is ranking, thus leading to great keyword ideas for yourself.
