Hi blog and ping works like this, setup a blog on blogger.com the theory is that once you do this then google will come and visit your blog once you start entering
content into it, I think the 24/48hrs is a bitunrealisitic but i got on yahoo within about four days ish, still not on google yet but i guess in time it will happen, Once you have done that if you don't have a yahoo account , e-mail will do once that is done, go to my yahoo which is in the middle then add your blog to there rss feed which in turn puts your blog on my yahoo then yahoo will visit so the theory goes. Next go to
www.pingomatic.com and put your blog in the form this sends your blog to about 10-15 blog directories which is called pinging it maybe a good idea to register with feedburner also so you can put your blog on as many rss feed sites as possible which drives traffic to it. I would ping once a day to much won't achieve a great deal. I
am showing up on the search engines slowly but surely after about 1-2 weeks
but as well as pinging i submitted my blog to a few directories also.
p.s when you setup your blog in settings you need to select add your blog to our listings select yes. On the settings publish make sure notify weblogs is set to yes.
