Do links de-value over time?

[darkroom]

hey guys,

I got a question. I'm sure others have come across this before too but here it is.

If a site links out to my site from an article, now Google knows when that link and article was added and stuff, so does the value of that link decrease over time (say for example 1 year) ?

Any inputs would be greatly appreciated!

There's a Google patent that looks at historical data with a view to link acquistion and retention. It's discussed at length here - [webmasterworld.com...]

If its a news article it probably gets deep into the site, so in that case yes as it's buried and no longer on the homepage where it probably originated.

I'd say it's not all one way or the other. Some backlinks grow in value over time, and others devalue. Google patents have accounted for both possibilities.
