SEMRush is one of the best solutions I have found for discovering site errors, getting a great explanation on how to fix it, and even posting for social media. It covers end to end so many of the varied areas of SEO, that it's become an invaluable part of my business. My favorite has been utilizing the ranking tools to see how we compare against competitors, and also tips on getting featured snippets (which we achieved for one client this year!)
There’s a reason why over 2 million people worldwide are using SEMrush. The reason is SEMrush gives you access to a ton of tools that you can use to find traffic generating keywords, analysing your competitors sites, find and fix your website SEO related issues, check out the top performing keywords and pages of your site, compare domains, track your keyword rankings and the list goes on.
Google’s bots crawl your site to determine its quality, and correct technical on page optimization is one of the main signals used. When you optimize your page based on the recommendations of the website analyzer, you can increase your organic traffic, improve ranking positions, and stay competitive against other sites ranking for your target keywords.
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.
