Determining the age of links

any way to do this?

[fom2001uk]

So we can find out a lot about backlinks

the linking page's URL
unique linking domain
Class C IP address
age of linking site
PR of linking page
cache date of linking page
inbound links to linking page
number of outbounds on linking page

but what about the age of the link itself?

This is surely key to how valuable the link is (is it sandboxed?, if so when did the clock start on it?, etc)

So I'm wondering is there any way of finding out how old any particular link is?

Span, I'm not referring to the age of the page (Wayback machine tells me that), but the age of the link. When was the link made live? That's vital because we know links need to age before they get credited. See what I mean?

Other than finding out exactly who placed the link, and if they remember when they placed it, I don't see any way of determining this.

Is that the case?

I was thinking to find the page in the archive with the link on it and then go back in history until you find the same page without link. Takes a lot of time, but it is faster and more reliable than finding the person who made the link and asking when that happened. Who remembers when a link was made? I know I don't.

Now I get you.

Great idea, thanks :-)
