Well as we all know, you need lots of backlinks for SEO. Based on the fact that you are chosing your own anchor text, I am assuming you are buying backlinks. If so, buy about 3 or 4 sitewides from large sites, and use two keywords each in each link. Let other backlinks come naturally. Create a "link to us" page on your website with a couple of suggested anchor text and url combinations someone can implement on their site. It will eventually even itself out because over a large enough period of time, the largest percentage of visitors will select the anchor text that contains the keywords most often searched for and most related to their own sites. Kills two birds with one stone: backlinks are targeted and contain keywords commonly searched for by visitors to the site linking to you.
Does that make sense at all?
