Did you add your Site here: http://google.com/addurl?
Did you check for some robots.txt files (maybe from a theme or framework) which forbids search engines (besides the wordpress backend option)?
Did you provide a sitemap? Sitemap Description from Google
Optimize your URL CANONICALIZATION. URL Canonicalization Description from Google
Check your meta-tags for robots-entries! (Theyre sometimes hidden in there)
If possible, add some page caching. Search Engines nowadays take that into rating as well.
If all of this does not work, it could be google has blocked your site during developement process (maybe for redirects or something). Its always a good idea to block search engines straight to the day your site goes live. If you do all above and still, your site isn’t showing up, you could do a reconsidering request!
Hope you can resolve your problem!
