Is server side or client side?

Hi. The tooltips are rendered on the client side.

Is there a way to run this server side?

The tooltips are using JS so it is always client side. Parsing the content to find where the tooltips are is done server side

In order for Google bot to scan the text in the tooltip on the page, it needs to be processed on the server side and added to the html. I guess there is no way to do this?

The tooltip text does appear in the HTML of the page so Google can read it. How it processes it it is hard to tell…
