subhshiv Hello, Heather here, yes an increased cache hit rate through Ezoic is a good thing as it means that we are able to serve your website pages to your readers faster and load up the ads faster too.
When a site is growing we are looking for the cache hit rate to be in the green, please don't worry about achieving a 100% cache hit rate as this would mean that you weren't creating new content or attracting new readers to your site through your content or marketing.
For your site do you have the CDN manager set up? This further helps your cache hit rate as it means that you don't have to manually clear your cache the Ezoic CDN will do this for you. You can find out how to do this here: https://support.ezoic.com/kb/article/how-can-i-set-up-the-ezoic-wordpress-plugin-for-cdn-management many thanks
