If a user Googles my company name, once the search results show my link in the search results, and before they even click the link, prefetching will begin with the resources I have identified in my above code?
I read it the same way. My objective here is to get prefetch my dns and possibly add some resources on my page to be prefetched upon search. I think of we are reading that the same this might be the case. I’m working on my page loading speed .
DNS prefetching is telling the browser to start resolving the IP address for the host name mentioned while the page keeps on loading so once it hits the resource you are linking to on that domain, like a font, or script, or stylesheet, it will already have resolved the DNS for that domain and can connect instantly because it has already resolved the IP.
It has nothing to do with google and/or ranking whatsoever.
