all these days my pages were indexed within 30 minutes and ranked well.. but recently i lost some backlinks but still i'm ranking high for those pages.. my problem is that google treats my newer pages like sandbox sometimes i see it in the results sometimes its totally gone. ex:- google.com/how-to-bake cookies.html is not indexed but you see "how to bake cookies" for google.com (no link to direct page) what can i do to make it right ?
I don't understand your example. What happens on my site sometimes is content gets indexed from the homepage so it ranks in Google but the actual page with the content hasn't been indexed yet.
yesterday when i checked my latest post which is indexed before, it also gone, then i deleted that post, then today i make new post with the same tittle, url and content and it get indexed within minutes, i don't understand why google deindex that post before.
This is a typical thing that can happen with new content. You will experience the "Google Dance" where your rankings will go up and down, but your rankings will stabilize after a few weeks. I have experienced the same thing with my blogs, so no need to worry (unless you are doing naughty blackhat things).
