I'm a tiny bit confused (partly because I've only recently been introduced to Ping.fm)...
Does this ping.fm WP plug-in automatically make posts from your RSS Feeds to the other social media sites that you have associated w/ your Ping account?
If so, that seems awesome!
I'll have to check that out.
And if it does & you're not noticing any added traffic, that's curious.
Are you making ANY regular posts yourself?
Are the posts that are sent out giving any real value to that/those niche(s)?
Is anything else being done to add followers/fans on those social media sites?
There are automatic tools that could help w/ that (i.e. that automatically add Twitter followers).
I think that these great tools should be used in combination with each other.
You know, add followers, fans, etc., then automatically post great content to your
pages, tweets, etc. that push traffic back to not only your Social Media sites,
but also to your AutoBlog as well.
At least, that's what it seems to me to be the thing to do,
based on ALL the massive amount of shit that I've been studying.
Hope this helps at least a little!
