How do search engines treat non-standard tags, in particular VUE?

Question

Search Engine Optimization

I am making a website that will use VUE+VUELIDATE for various forms, but the main content is in html. There is a desire to use on the content pages of the site All sorts of embellishments from VUELIDATE (buttons, etc.), but for this you have to wrap everything in Won't this lead to unpleasant effects? <v-app><v-content></v-content></v-app>

Answer 1

Here you need to understand that in SPA Applications are cooked at the front, and search engines (although they are trying to do something) do not like SPA, there are of course solutions to this problem, for example, to make a server prerender (SSR) specifically for search engines, and if in more detail,
then you can determine who is accessing your server, a user or, for example, Google Bot, and based on this data, transfer either a rendered page or SPA. But all this is not very good, so it is better to use SPA for the development of projects that do not imply search engine promotion. For example, the admin panel, etc.

Answer 2

All these , etc. - these are just the names of the components that are wrapped with regular divs, and are rendered to the page by regular divs <v-app><v-content>
