This is very strange situation to me i don't know if this is normal. My site which is very well listed in Google and it's all articles were quickly picked by it in the past. Now when i check my log files i see Google and other search engines are crawling my site twice a day.

Since 3 weeks all the new content i add to my site are not indexed by Google although they follow those links very well. Those articles are unique and i don't expect any dup content issue.

The similar problem is with Yahoo they have listed only three out of 50+ page from my site over 6 months, but they visit my sites almost thrice a day. if they don't want to index them why do they come? Is there anybody experiencing the similar trouble? Help me out...
