I also have blog which get cached by google as soon as i post. I thinks its normal and happen with lots of blogs but still give good feeling that my blog is in special group.
The idea is to have the content updated as frequent as possible and once update is done, it should be followed by ping.
I don't have a blog, and if I make a new page, and make a ping to the respective page, google will take it in max 30 minutes.
Google loves blogs, and text in general. I use Wordpress, and get indexed several times daily (I update constantly).
Are you an AdSense guru ? =)) Looks like your blog is all about AdSense, keyword stuff in url, titles, descriptions, everything lol How is your CTR? with those huge Google Ads that blast every visitor's eye... I wonder how much will you still be in the program
That's great. I've not checked so quickly but I usually checked within the day and it gets updated. I think a high PR blog helps too. Peter Lee
nice job...even though it may be normal! it's good to know that your site is indexed through and through.
Really good for you considering that your site seem to have a lot of content that are not very unique.. Maybe google is checking out to see when you trip their duplicacy filter. Just run a copyscape.
I agree with ms. cora (I mean, hershey!) that the more frequently your blog was updated, the most frequently Google spiderbot with crawl and index your blog.
