The web is not yet fully ready for CWV.

Be sure to review the metric-by-metric breakdown of the most common issues on your specific pages, as the Site Audit really shapes the problem to include the solution.
Summary
With the Core Web Vitals update now here, you have no choice but to improve your score across all three metrics (CLS, LCP, and TBT) to show Google that your pages are highly usable and deserve those rankings.
We hope that our study, which covered a lot of ground and revealed key insights, provides clear guidance to further support your optimization efforts.
While we encourage you to take another look at all of the findings, there are a few things you should take away from this study:
Only a third of desktop URLs and 3% of mobile URLs exceed the thresholds for all three CWV metrics.
Since the update, we've only seen widespread improvements on about 1% of pages. And just under 40% of them scored better on at least one metric.
This means you likely have plenty of room for cambodia phone number database improvement, and if done right and early, your on-page optimization efforts can give your pages a competitive advantage.
Pay special attention to your mobile pages.
Most of the checks for desktop are green (i.e. passed), while for mobile, we see mostly yellow and red. This means that it is easier to pass audits on desktop than on mobile, and that mobile sites face more issues on average than desktop sites.
This is most likely due to mobile thresholds and the fact that the lab data is simulated on a 3G device.
Work on your LCP (mobile) and TBT (desktop) scores.
With CLS as a less “problematic” metric, you need to work on improving your LCP and TBT scores:
CLS improvements are more likely to give you a quick jump from the "poor" to "good" score bracket.
Audit your <img>, <div>, <p>, and <h1> tags to make sure they aren't dragging down your LCP score. Use the Site Audit tool to locate the page elements that are causing the slowness.
Keep your total block time under 300ms to ensure a “good” TBT score. Again, the Site Audit tool will help you determine which long tasks are hindering your overall TBT score the most.
Keep an eye on the extent of your layout shifts and get rid of those that take up too much space from the CLS threshold. The Construction Audit reflects the contribution to CLS of each of the largest layout shifts.
Be careful with the height and width of image elements and other common CWV issues.
Take a second look at the most difficult audits to pass. Most issues—on both mobile and desktop URLs—occur with image size. Since this is a CLS-related check that has a fairly quick fix, you can use it as a quick win to improve your CLS score.
Keep your expectations reasonable.
For desktops, the most common change is from the “improvement” to “good” range. But most mobile URLs jump from the “poor” to “improvement” category, with the only exception being CLS. So don’t expect to quickly go from all “poor” scores to all “good” scores on every single VCC metric, and keep an eye out for any changes in the thresholds.
