Technical SEO is about more than getting higher search rankings or driving more traffic from organic search results. Rather, technical SEO is about making the website better for users. One of the best ways to identify technical SEO issues is through usability testing. During a usability test, you recruit participants to use your website while you watch. As you watch people using your website, where do they struggle? What confuses or frustrates people about your website? Where do they run into dead ends or other impediments? Chances are if people are confused, frustrated, or unable to use some aspect of the website, search engine robots will have issues moving through the website too. Keep in mind, Google is, in many respects, trying to emulate how humans use and think about websites as they make determinations about what to show in search results.
