There are certain things to look at when evaluating SEO performance. First of all, the number of organic visitors the website is attracting. This is an important factor as the traffic gathering on your website should be organic. Another factor is the time spent on your website. If the users are spending more time, this means that the content is engaging and interesting. Another way to measure SEO performance is by bounce rate. This shows the number of people that leave the website without checking out what your website offers. The higher the bounce rate, the higher people leave your website without any interaction.
