I had recently published a blog post “Google Crawled my blog post in 32 min” well its no surprise or it’s not a miracle anymore, it’s actually a part of the blog services which Google accepts once after we published blog posts.
I started looking into deeper on how does Google actually crawls so quickly and later I found its a part of any blog service that it pings back all the blog search engines, and you can call it as “ping-o-matic“, In my observations once its published it will crawl and index quickly, however once its indexed it doesn’t re-crawl it again as quicker as it does for the first time, rather we never known when does it index for the second time if you make any further changes for your first time published post.
Just to give an example,
When there is a recent bomb blast in Bangalore, I was aware thousands of people start searching with keyword “bomb blasts Bangalore” however I wanted to check with the low traffic relatively so I updated my blog just with the heading, “multiple bomb blasts Bangalore” mentioning about the current situation of bomb blast thinking and also testing on a. whether it crawls very quickly posts which are recently published b. whether it will re-crawl if I edit it for the second time (You don’t believe my blog got suspended due to heavy traffic in a short time, Later I called the server administrator to make it to live again)
The moment I published it immediately crawled and my site was appearing in the second page for the keyword “bomb blasts Bangalore” and first page for the keyword “multiple bomb blasts Bangalore”, thats the ping effect within wordpress for every post published.

My second tests is to edit with the heading if it recrawls the changes, I changes my post heading to “Bomb blast in Bangalore, This time its Multiple” however even after 24hrs of time it not crawled the edited content.

Just to mention little bit more about the ping effect for Google, Last year Google has announced “Google Blog Search Pinging Service” where we can either ping Google Manually or We can set it for Automatic. Any Wordpress installed by default pings Blog search engines automatically once posts are published.
Here are the inferences
- There is NO surprise if the Google crawls the recently published post immediately and ranks in top of the page.
- Google might not crawl of index the edited content of the same posts.
- Blogs have or can have auto pinging service which pings all the blog search engines once posts are published.
Let me know your thoughts please, Just in case

nice info, I need to index my blog..

I’m not really sure about how exactly Google crawls & indexes a page. I changed my blog address to custom domain last month. Most of my blog pages are reindexed by Google Web search, but disappear on Google Blog Search. Could you or anyone explain it? Thanks,

This is very interesting, I was wondering why this happens.
Thanks for the info.
