Google problems

Hi guys i’m a wordpress newbie and I just built my site last week. But now that i’ve been looking into SEO and how my website shows up on google, ive noticed a few problems… First off when I put site: in front of my web address (ex. site:corridorlawns.com) only the front page and and a post show up, none of my pages do. Secondly, I can’t change my tagline or the “snippet” below my site name and tagline, I have tried deactivating all my plugins and doing the ctrl + F5 trick, and nothing seems to work. Thanks!
