Hello. If you mean when someone reaches out and invites you, names are cycled on the search engine, so your name would be on the first page every so often. It depends on how many people are in your category, but I find I get invites once a month for a day or so and then nothing. That is likely when my name cycles to the first few pages.
If you mean why are people not responding to your job applications, then just keep on trying, or try a new tactic with your application letter. I've been here for years and I get no response to many applications too.
Don't give up.
