<h4>Idea Behind</h4>
There is no need to say that performance IS very important. 
What’s also important — is to understand whether you have to worry about your website performance or it’s doing fine.
Google Core Web Vitals are the metrics that Google uses to measure the user experience on the web (real user experience!).
If your website passes CWV assessment for Origin — it means that your website is fast enough for the majority of users. 
If it doesn’t pass — it means that you have to fix this. 
If it does pass but quite a few specific URLs are not passing — it’s a good time to look into those URLs and improve them to prevent the entrire webstie to be marked as failing CWV.
I wanted a simple easy-to-use tool to warn me in case my clients’ websites performance has a bad tendency and needs my attention.
I wanted a native WordPress solution, with all information available from the dashboard, simple but still informative, a guard who will do the monitoring every day and ping me, in case something goes wrong.
I have not found one and that’s why I’ve built this plugin.
I’ll be happy to know that you find it useful as well — please, leave a review.
P.S. Note about PageSpeed Insights: you SHOULD always use CWV data in case it is available for your website. In case it is not available (when the website is new and/or doesn’t have enough traffic yet) — use PageSpeed Insights. But you have to remember, that PSI — are lab tests, it’s just an emulation of real users experience. It’s better than nothing, of course.
