Why home page URL won’t show anywhere within the search results?
JOHN MEULLER (Webmaster Analyst from Google):
So oftentimes we do show the home page as the first one for site query, but it’s not guaranteed. It’s not something that our systems always do. So specifically a site query is something that we would see as an artificial query, in the sense that there is no correct ranking for us to provide there. So that’s something where it’s not really a sign of an issue if you’re not seeing the home page on your site query search results from the beginning. It’s not really something that you need to fix.
