LSI and Link Popularity
“Link Popularity Building Best Practice: Vary Your Anchor Text ”
Increasingly, link building for a site needs to be handled with greater levels of finesse. It used to be (as in 6 months ago) that you would just buy hundreds of links with the same title and description which honed in on your main targeted key phrase. That technique is easily distinguished by the engines and consequently is getting people excluded from the indexes for those very phrases.
So the moral of the story is: Mix it up. Use multiple variations of your title and description for link building. Anything that is replicated over and over again is going to probably do you more harm than good.
