Not showing in searches

I have been monitoring stats over the past few weeks and wondering why I am not getting many referrals from search engines.
I have gone to google and put my domain in, it came up.
I then put my domain with the title of one of the listings, this showed nothing, and repeated this several times with random listings, none of these showed up.
Is there something I should have ticked here to show up in searches? I am concerned that if I don’t show up in searches when searching by listing title, I wont be found.
