Pinging and rss feed directories have a lot to do with it.
I just wanted to say that I'm amazed at how quickly Google seems to index (some) WordPress blogs.
In the past, I've made several websites "manually" (i.e., all hand-coded .php and .css files, starting from scratch), and it takes days for Google to notice when I add new content to those sites. But with my latest, WordPress-based sites, new content (posts) appears in the Google index (as discovered using the site: search) within a few hours (certainly the same day)!
Perhaps it's something to do with this pinging malarkey. In any case, I'm now a bit reluctant to go back to hand-coding sites; WordPress-based sites seem to have a real advantage in this sense.
That's why I like WordPress. But it has definately a lot to do with the ping services WordPress is using and normal sites aren't
Pinging really helps a lot IMO.
some of my new sites got indexed within 48 hrs of creation...
All are based on wordpress...
Some of my Wordpress sites take less than 30 seconds to get crawled and indexed.
great to know this as i haven't notice. i only notice that my visitors keep growing/
