Lots of posts on here that using Social Bookmarking is a good way to generate traffic and a good SEO method generally. Is there an up to date list or directory or something similiar that lists them all ?
I have sorted through many of the lists and, to be honest, most didn't do anything for me. I suggest researching and testing each social bookmarking site (reddit, propeller, stumble, digg, etc.) and see what works best for your product/service. I hope this info helps. -AS
There is no update lists. Even if the guys have it, they will not prefer to share it. However there are lists which includes lots of invalid sites. You hve to check them and create a list and keep up to date everything. Actually, bookmarks help a lot to get index quicker from google as well as offer good backlinks too.
