As the original poster, I think I may not have fully explained my situation.
My site offers a directory of other sites in four vertical markets. Most of my backlinks come from universities and other professinals. You can see the main site at
www.usernomics.com .
However, my business interest is in the few visitors I get who are looking for consulting services. So generating more visitors is good, but not likely to result in the people looking for consulting services.
Now I have a News Aggregator as a blog on my site that has about three articles per day. But they are not my original articles so they are not likely to be picked up by Digg, etc. You can see this at
http://www.usernomics.com/news/user-...sign-news.html .
I now rank in the top 5 on Google for:
Interface Design
User Interface Design
Human Factors
Ergonomics
Plus in the top 5 for various derivatives with: consulting, consultant, and company, e.g. "user interface consulting", "human factors company", etc.
So I think that adding links within Digg, Wikipedia, Delicious, etc. probably would not do me much good for those consulting customers. I do have links at the end of each article where others can post to those sites but I am not posting to those sites.
Does that make sense in this case?
Thanks,
Bob
