How do you determine how much a link is worth?

[Oren.]

Obviously things like Mozrank, domain authority, relevancy signals, authority signals, and other fundamentals are a great starting ground, but I was wondering how people put value on a links.  How much time is a link from a page rank of x or a moz rank of y worth.  How much time, money (not in terms of paid links, but in terms of manpower, copyrighting required, etc.) is a link of a certain rank worth.

Obviously there is no exact answer to this question, but I'm very curious to see what people have to say in this regard.

Depends what you can do with it..

If you have an ecommerce site selling high value items with a great conversion rate and very high customer lifetime value that link will be worth 4x as much to you as the guy with 1/2 your conversion rate and 1/2 your profit margin.

The link might be worth even less to someone running an adsense site on a noncommercial topic.

Also, it depends upon the maturity of your website.  If you have a new site with very few links then a new link can be kickass.  However, if your site is established with thousands of links then one more will not have a dramatic effect - unless it is a valuable link that hits a relatively new content page.

Yeh, I agree with EGOL.

Another thing to consider is checking out your competitors profile.  Say they have 100 links, and 10 are noticeable better (higher DA, PA, relevancy etc) it would obviously make more sense to spend more time on those 10, and in fact you may not want to spend any time on the lower quality links (i.e. you don't want them).

But yes, for the points EGOL mentioned its not a simple question to answer.

I got by # of visits, interaction on the site + and on its social network sites - by both themselves and by readers/visitors.

and how often the blog or resources are updated.
