Can search engines read what your pages say? Search engines can't read, but they can get an idea of what your page is about by measuring keyword density, the hierarchy of information and dozens of other criteria. An SEO agency can track all aspects of the strategies they used, whether it's ranking, conversions, or traffic. Comprehensive analytics means you can zoom in to granular levels of data and see demographic factors of the users who engage your site. You can actually track the very keywords that lead to sales and lead conversions.
