We've gone over four tools, and the fifth tool has to do with your SEO and SEM. This tool is called SEMRush. It is one of the most versatile SEO and SEM tools out there. From keyword research to competitive analysis to even social media management, this tool allows you to do it all from one platform. Now, it is not a remarkably cheap tool, so I'm going to put that out there. It's actually one of the most expensive tools we talked about today. Their cheapest plan is $119 at the time of writing this post and that plan doesn't include all of the features that we just outlined, so keep that in mind. Now, they do allow you to do a little bit of keyword research and market research for free every day. But you only get between five and ten queries that you can perform ad day for free. SEMRush also has classes that you can take for free that will teach you how to do SEO and SEM better. So it's quite a versatile website. If you are looking to level up your SEO or your SEM, this is definitely one that I would put in your tech stack
