Presented live at Mozcon 2019: Google's algorithms have undergone significant changes in recent years. Traditional ranking signals don't hold the same sway they used to, and they're being usurped by factors like UX and brand that are becoming more important than ever before. What's an SEO to do? The answer lies in testing. Sharing original data and results from clients, Rob will highlight the necessity of testing, learning, and iterating your work, from traditional UX testing to weighing the impact of technical SEO changes, tweaking on-page elements, and changing up content on key pages. Actionable processes and real-world results abound in this thoughtful presentation on why you should be testing SEO changes, how and where to run them, and what kinds of tests you ought to consider for your circumstances.
