You don’t ping googlebot as such.
If yahoo is there, googlebot will follow.
If you registered then a link would help the bot find you ?
yahoo.net is associated with one of the services from pingomatic so its not exactly yahoo serps.
Google uses pingomatic or one of those as well I believe.
You can also use this plugin to be sure: http://www.arnebrachhold.de/2005/06/05/google-sitemaps-generator-v2-final
Using pingomatic would definitly mean that googlebot is being pinged. And as far as i can tell, their blog search updates fairly frequently.
However, this does not mean you’ll be included in the actual google search listings yet.
webalizer should definitly show if googlebot isthere. if not. It just means googlebot is slightly slower.
(do note pingomatic only pings google blog search. not it’s actual search pages)
or u could use a stat plugin like http://www.randypeterman.com/StatTraq/
I just use Gamerz’ Useronline plugin and I see several times a day my dear bots happily grazing my content 🙂
