Facing Problem with Indexing

Hi, I have an issue with my blogs that they are not getting indexed by google. The last crawl was done on the 25th of May.

But I regularly create content and publish it but due to this issue, no one content is being indexed it's very frustrating.

Also used the free ping service and created some backlinks and social bookmarking as well.

But no result.

Please suggest some solid and proven solutions. If you are also facing this issue related to indexing from 2..3 weeks then please share your experience also.
