it shows that my site have been indexed 120000 pages by google ,but it can not help me to increase the traffic,less than 1000PV a day,why ?
I think it depends on your keyword. Have you checked the keywords and if it is a popular keyword you should get lots of traffic
Are most of those pages in the supplemental index? If so, don't expect them to get much search traffic I'm afraid.
what is "supplemental index" ,what are the differences between supplemental index and normal index ,i found that it shows the indexed pages is not normal ,you can see this :http://www.google.com/search?q=site:highpayinggoogleadsensekeywords.info 17700 pages are indexed ,but there are few pages in the google search results
If google doesnt find relevent results for a keyword, then it shows results from supplemental index. Try to move your pages from Supplemental index to normal index. Add good content to your pages in supplemental index. Get a few good backlinks.
