During a hangout, one SEO professional asked John Mueller about web components for SEO.
Their question was: Is there any problem with using web components for SEO? Is it okay to use them for my website?
John explained that web components are essentially a way of using predefined components within a website.
And the benefit of these components is that you don’t have to reinvent the wheel every time that something specific needs to happen on a web page.
For example: if you need a calendar on one of your pages, then you just use a web component for a calendar, and then you are done.
The best way to do so is in Search Console, where there is the inspect URL tool. There, you can insert your URL, and you will see what Google will render for the page for the HTML.
You will be able to see it on the screenshot, first of all, and then you will also be able to see the rendered HTML.
You can also double check what Google is able to pick up from your web components.
And, if you think that the important information is there, then perhaps you are all set.
If you think that some of the important information is missing, then you can drill down and try and figure out what is getting stuck there.
Furthermore, be sure to look up documentation from Martin Splitt on John Mueller’s team. He has written a lot of this documentation. Martin can also be found on Twitter.
