Neither a Report nor an Audit - I offer THE SOLUTION
You can use some of Google's free tools like Google's PageSpeed Insights tool or better yet Google Lighthouse to check your scores and check for any issues that are slowing down your site or causing other problems with your pages.
If you're here, you already have it. You've probably taken this data to your designers and programmers, and they've probably been able to fix a couple of those issues, but they've also said "That's all we can do"; however, his scores are still not great.
Why is this important?
By measuring user experience, Core Web Vitals is now a key factor in ranking on Google Pages.
Check out Core Web Vitals for desktop and mobile versions of your website pages. The result of the CLS, LCP and FID metrics can be 'good', 'needs improvement' or 'poor'
In LCP, the content of a single page must load in less than 2.5 seconds. An FID of 100 milliseconds or less is perfect. A good CLS should be below 0.1.
The solution is to have an expert who understands what can be done with your site once it's in the cloud so you can maximize your scores.
