Why would you want to link to your competition?
The true purpose of a link is to benefit your visitors. Sending them across the street is not benefitting them becuase you are the best!
You want "related" not competing links.
PR7 site with a text anchor is great, especially if it is a related service that serves your visitors.
me, I would get my site listed in the top directories, and get text links from related sites with customer focused design. Someone else, will tell you something different.
But we can angle a bit towards quality and quantity vs just quantity. Think of Google and their customer centric philosophy, and strive to get ahead of the curve ;)
It seems, that it all works, for a time, but the real quality stuff, keeps on working. Like the clean and dirty
seo debate. Dirty
seo works till it doesnt, clean
seo keeps on working, so you choose ;)
