Propably they have a db with all websites with 'blog' as keyword. Besides that they probably search subdomains of blog hosters such as blogspot.com
I think its automatic MadKad. I get some good traffic from there and as far as I know I didnt do anything special.
Have you tired looking for yours in there? I think we discussed something about this in V7 and also the connections with answers.com - another place that I started getting traffic from.
I have looked but cant seem to find it lol, looking at what Michael has showen us then I need to ping more but I am just lloking into this pinging lark lol thank you every one and thank you Michael for the link
Hmmmm... The googlebot hits me soon after I do a ping - maybe they are coincidental. Ah - try this also -> www.google.com/reader/ I have my feed in that to make sure google can read it. Maybe that is related??
could be i will look, I have google on my site all the time so i wouldnt know if the pinggoat helps with that but i know it doesnt help with visitors in any way well not for me
