I know adding to Webmaster Tools for PBNS is a death wish. But how about just submitting the URLs of your PBNs to Google ? Is it a footprint too ?
If it's OK to do it then how you do it? I mean, do you just submit all the URL's from the same IP or use different IP's to submit each PBN ?
Just asking cos submitting URL really helps getting indexing quicker.
If it's also a footprint, then how to get your PBNS indexed ?
Do you just let them get indexed naturally over time, or you ping them on a service like Pingomatic.com ?
