Not all urls indexed with submitted sitemap

I have submitted sitemap using Google Webmaster and I see 28 url submitted and only 23 indexed. Why? Google say for themselves that if url is not indexed but it is presented in a sitemap it can be because of duplicate content, shallow content or some other reasons that violate Google rules, but I have only original content on all webpages and can't see what is the issue. Any thoughts?

 

I'm also facing the same problem if somebody can resolve our issue then please do suggest what should we do.

 

Same problem for me as well. I have good unique content. Google crawls my site but doesn't index. No idea why :-(

 

As I know Google will index all urls day by day, just be patient.

 

Guys the issue resolved it took me 5 days to have submitted urls = index urls by G

 

Good for you. I'm still waiting for the past 10 days. What was your issue and how did you solve it?

 

Its happen to me also but after some days google indexed all pages of my site.
