Measuring and improving your keyword and content performance is an ongoing process that involves tracking, analyzing, and adjusting your SEO strategy based on the results and feedback you get. To do this, utilize SEO tools like Google Analytics, Google Search Console, and keyword rank trackers to monitor website traffic, rankings, conversions, and engagement metrics. Additionally, use SEO audits such as content audits, technical audits, and competitor audits to identify any issues or gaps that may affect website performance. Furthermore, SEO experiments like A/B testing, content updates, and keyword optimization can help you compare different versions of content and keywords. Finally, utilize user reviews, comments, and surveys to understand audience satisfaction and preferences in order to improve content quality, relevance, and value.
