I have setup my blog http://revhardware.com and have written lots of articles now, but I have only ever had 2 pingbacks on one of my first articles... I thought I would get quite a lot? How do I tell if my blogs pinging correctly?
Pings and pingbacks are two different things. Pingbacks are received whenever someone else links back to your articles, while pinging services (using the rpg.pingomatic in wordpress, for example) simply announced the services that you have posted. So these two are not connected. If that was not what you meant and you actually hoped for more pingbacks, well... you should be patient and continue writing good content and hope for the best, eventually people will start linking back to your site!
It's just from experience on past blogs I had a LOT of pingbacks especially from "made for adsense" type sites, whereas now I'm getting none?? I am unsure if my site is pinging properly to let people know as I think nobody is actually seeing my articles to be able to ping them back.
