Hi, I have a question about backlinks. I made an 11-hub link wheel a few weeks ago for a niche site using a keyword-based domain. I did a random link order and didn't close the linkwheel. I social bookmarked each linkwheel hub on Digg, Stumble, Delicious, Reddit, Mixx, and Diigo. Today, I checked Google Webmaster Tools and only see 1 backlink which is Hubpages. Any idea why I'm not seeing them all?
