Are you running the two sites together? i.e. are you using site XYZ to market or boost site ABC. If so, instead of putting a static link on all your pages with the same link text, mix it up. Use various link texts in differnt articles in different pages and don't always link to the same page i.e. your home page.
If it's links from other sites that you don't own and have nothing to do with your business as such, then I'd suggest one link from a page that's got either good PR or good search rankings for keywords they're targeting and use good LINK TEXT.
It all depends on what you're trying to achieve really and whether or not you manage those sites I suppose.
I'm doing an article marketing campaign, so I can't control where my link will be on XYZ site, I also can't use anchor text.
I can however control the landing page on my site.
Something else is that I could put 3 different signatures on every article to point to 3 different pages on my site, would that be benificial?
I'm doing this because I'm creating a task will distribute articles to over 150 article banks, some of them with PR6.
That will be 150 icoming one way links and I think it will be a valuable service to offer to webmasters, especially since all the sites will be confirmed to exist, accept articles, publish articles and keep them online.
