#8046 – 4SEO - Core Web Vitals and Custom Components
What effect does the 4SEO module have on Core Web Vitals scores? Does it help with increasing these?
No, no plugin can really do that aside from the usual optimization techniques such as caching, reducing image sizes, etc.
What 4SEO does is measuring real Core Web Vitals for your site. As far as I know, it's the only plugin (for any CMS) that provides you with real CWV values for you site. Usual performance measurements tools such as webpagetest.org or even Google's own lighthouse only give you readings of your CWV, when you visit a page.
But that's not what Google uses for ranking. They use real measurements from real visitors to your site and that's what 4SEO can measure for you, so that you can optimize actual Core Web Vitals.
We also have a lot of custom components that create URLs that can be accessed on the web (we mainly do auction houses so they have different URLs for all of the items that they are selling).
4SEO will crawl any URL of your site it can find a link to, so how the page is built does not matter in principle. The amount of data it can gather however depends on how your component was built and whether it complies with the Joomla API (for instance correctly throwing the onContentPrepare and other events).
Then you can of course dive deeper by using the many documented hooks of 4SEO.
