most people are likely to know how to get to linked in, but your webserver... not so much.
I mostly just crosslink across reputable, indexable domains and make sure the same keywords show up everywhere that’s possible. :-)
But, yeah, nothing seems to think my web server should be in the top ten of any keyword search.
I think there is a misunderstanding here. Things work the other way around. People do not seek you, linked in takes you to them.
A recruiter more often is looking for people with your skillset, than looking for you specifically.
In other words they are not typing in your name into a search engine, they are typing "aws architect python" etc.
If they were seeking you specifically, they probably already know enough about you and will just get to emailing you directly.
