How google can prevent cheating the age filter

prevent black hat getting benefit from aged domains

[bytb]

Most domains aquired by black hat seo are aged to try and get there sites recognised as an authority on the subject by buying an old domain that typically is loosely related to that subject.

Most of these domains the home page was wiped out at some point. Thats why there for sale. I think if google look for a consistancy of home page appearing in there index, those showing a long gap could have there age filter reset to when it first reappeared in results. Google would in my opinion then need to work out the difference between the average time a hijacked page is returned to results and a banned page is returned to results. I am guessing here but I rekon to filter out domains falsely using aging filter look for an 18 month gap in there listings historicaly on google.

Google is pretty efficient at resetting doamins to zero when they change hands.

That's why a web site that is sold 'as is', rather than just the doamin, it's important to arrange a smooth transition to avoid losing all 'credit'.

Domain buyers who use totally new (=different) content get little benfit from the previous life. Just a few refrrals from old links, most of whom will leave immediately on not finding what they expected.

So no worries there!

This sounds good but doesn't add up I am afraid, Black hats are openly posting on webmasterworld how they cheat age filter. I am seeing authourity to sites registered and banned and then reregistered. Yes there may in some cases be a penalty but once its complied with seems to accept age content back to original date of domain.No check on content at all.
