Site 17% indexed by Google. Please HELP!

I have trouble in google sitemap. My site is online more than 2 years.

9,170 Submitted

So poor! I am so disappoint:(
Please HELP!

Is that poor, or fairly normal? I have 248 out of 1902 indexed (13%). But that is all my actual pages, the others are urls for many different things on the site and I don’t think it really matters whether they are indexed or not.

17% is poor, and can say 100% bcz its >2 yrs old. so need to do some good work on it… Better keep updating slightly every day and re submit sitemap after update. and see the difference, if no chances for a month have to work more
