How come Social bookmarking sites are indexed instantly is it some trick. Do they have something special powers given to them by google ?
Yes.. That might be one factor why they are instanly indexed by google. Another factor might be because they are high quality websites which means that the website has high PR, regularly updates and etc...
Social bookmarking has the ability to let google spider the links because the site is frequently updated with new members and post content on description of every links..
Exactly...content is updated too frequently on social bookmarking sites that attract google spider to crawl that page..
Content on social bookmarking sites was updated regularly for that reason sites are indexed instantly
You don't have to be famous to get instant indexing. Almost all of my blogs do it because they PING and have a lot of incoming links. Plus the content updates quickly so Googlebot is quite interested.
Sure. When a blog updates, the blog script uses a mechanism called "PING" to notify the major blog search engines that a new post has been made. They update immediately.
The content on social bookmarking sites are update regularly and Google like site that update the content regular, and the ability to ping Google about the latest update. For that reason social bookmarking sites used to be index instantly.
Even i have a active forum which is updated regulary like social networing sites but still it doesnt update qucily maybe i need to research on the ping thing
if you continue to have new content google will come more often, popular pages can be crawled every hour by the bots
I think another reason social bookmarking sites are indexed relatively fast is because google respects them.
if you write new posts everyday, google will index your sites within 3 minutes after you write your post. google bots are very clever.
