How is this better than normal analytics?

Standard analytics platforms on their own really only focus on the raw data and report on how it’s being accessed. SEMRush goes far beyond that and actually breaks down the contents of your website. Finding and suggesting what content needs to be improved and how to improve it is intelligence that neither Google Analytics or Google Search Console offers separate or together. This makes prioritizing your SEO efforts easier and more successful because you are working on what needs attention and what will provide you the biggest bang for your buck.
