Why my website not show in Google search results?

[zeus]

Hi All....Why my website not show in Google search results? We did SEO work from last 4 months but still not show my website in Google Search , please suggest some solution to fit it and show in Google Search atleast last pages....Thanks

What exactly in SEO you have done?

Have you not submitted your site through webmasters tool?

And if it's been 4 months then you might wanna check your robot's.txt file because it seems to me your site is blocking the search engines to crawl and index.
