Another tip is to go to YaHoo Site Explorer and enter the URLs of your top ten competitors for the keyword phrase you are targeting. You can see all (well, most of the back-links for them and get back-links there yourself. You can often find hundreds of such back-link sites. You will find many more back-links with YSE than using "link:" with Google.

I won't get into the LSI thingie here--most people don't believe there is such a thing. But I can assure you there is. Not only will using LSI help your money pages rank better, it can drastically help your articles show better in Google. Use it in your video descriptions as well!
