The more complex approach would be to determine a score based on position, number of other links on the page, degree to which they are related, degree to which the website is related, clicks from homepage to the link page, anchor text, alt and title tag possible or not, etc.

But frankly, I don't think it is worth the hassle. If your site is content rich, link from the bottom of your articles to pages that will be useful for your users and ask only for similar links from other webmasters.
