When evaluating Technical SEO tools, I prioritize site auditing depth, crawl analysis accuracy, and issue detection quality first, because these directly determine how effectively technical problems can be identified across a website. Next, I look at performance monitoring features such as Core Web Vitals tracking, page speed insights, and indexing status, since these help measure real-world SEO impact over time. Finally, I consider reporting capabilities, usability, integrations (like Google Search Console and Analytics), and scalability, because a good tool should not only find issues but also clearly communicate them and fit into a repeatable workflow for ongoing optimization.
