Why some website has no CrUX data available at all?

[Kunapas Thongpiam]

Hi guys,

I check this website and quite amaze why it doens't much data points at all despite being indexed on google properly and been in business foe years?

CrUX data is not related to search engine results. 

If there is no data for the origin, that may be due to not enough people who have opted in to have data collected from them have accessed your site. 

According to the CrUX Overview (https://developer.chrome.com/docs/crux):

The data collected by CrUX is available publicly through a number of Google tools and third-party tools and is used by Google Search to inform the page experience ranking factor.

Not all origins or pages are represented in the dataset. There are separate eligibility criteria for origins and pages, primarily that they must be publicly discoverable and there must be a large enough number of visitors in order to create a statistically significant dataset.

I think the reason this origin is not in the CrUX dataset may be that the root page redirects (from "/" to "/th")  - and because it does, sometimes a system that we depend on thinks that the home page is not publicly discoverable, and so we remove the origin.

Sorry about this. We've had problems with this pattern before - I've added it to our internal bug, which pings the responsible team.

PageSpeed Insights (PSI) follows the redirect, and displays URL level CrUX data (but no origin data) for the URL after the redirect (from "/" to "/th").

The lower part in PSI's report, after "Diagnose performance issues", is not based on CrUX data, but it could help diagnose performance problems.

If you'd like a time-series of CrUX data for the URL after redirect, you can plug the URL into CrUX Vis (or another tool), and find that here:

Good wishes!
