Lite allows you to have a 7 day trial for $7. After the trial ends, it costs $99 per month or $990 per year. This plan allows you to track up to 5 projects (websites) and track 500 keywords per project. You can search 25 batches of keywords per day, but you can search up to 10,000 keywords per batch. I like to use it to search multiple ideas for long tail keywords at once so I don't use up all my searches.
Provides a way to track the effect of link building activity and demonstrate the impact on search traffic. Excellent for competitor analysis. Helps with researching what content to produce, which competitors are gaining in search and why, which keywords your site could realistically aim to rank for, and gives you enough information to plan how to do it.
Pros: SEMRush is a full-fledged powerhouse for SEO building strategy and SEO audits. It's pretty beefy, so I would only recommend it if you have the time and patience for SEO, as the software gives a ton of outlets in looking up actionable items for your SEO Strategy. The first thing that I really liked with SEMRush was the initial SEO audit of my site -- I was able to see what's good and what's bad about my SEO, and the quick errors or warnings for title headers and ideas for gaining more traffic was awesome. Moving on, I found their analytics just as good as Google Analytics, showing me where my traffic is coming from and where I can improve my paid search positions. I haven't used the Social or Content aspects of SEMRush but social listening looks to be baked in well and integrated nicely. If you're in the market for seeing how your organic and paid search traffic plays a part, and then strategizing in how to improve your overall position against organic search and then your competitors, I'd recommend SEMRush.
