How to do link checking in the age of parked domains?

Checking for semantically brocken links

[conficio]

Well, I just saw the great results of a broken link check program. Looked rather good with lists of links and where they originated from. It also had a list of links where the target was redirected to another page.

However, in this age of domains that are released by their owners, how does one detect links to doamins/web pages that do not have the same content anymore, such as domains that have been bought up by speculators for their directory entires and their PageRank and are parked somewhere for the obvious reason.

Any ideas how to go about this in an automatic way?

You can also contemplate ways of detecting domains that appear to be the same as they used to be, but in actuality contain scraped content from archive.org

Ian,
very interesting "domains that appear to be the same as they used to be, but in actuality contain scraped content from archive.org."

Ian would you have an example? Can you send me a PM with it?

Thanks

For accuracy you can't beat your own eyes.

I cannot eyeball every link as often as I would like but when I have a quiet minute I do click on a few and look at the target sites in detail to see, not only if they exist, but also if they are up to date. I keep a checklist of when each link was last reviewed.
