Using hex coding of a page’s content, some clever folks have found a way to make it appear that they had links coming directly from high-level authority sites. Dannomatic at Threadwatch points this out:
-
Notice the formatting using HEX code when surrounded by a standard HREF tag this translates the link properly when the request is made to the authority websites POST for search – the result is properly translated into basic html. This is a clever coding exploit, this format ensures the request is properly formatted in basic HTML.
– -
Obviously the request is a negative search result on the authority website, however particularly site searches will cache all results of local searches, successful or otherwise.
– -
If these search results are spiderable content, then a robot such as Googlebot will view the cache results and see inbound links from a high profile authority site point to the domain in question.

I love seeing exploits and tricks like this talked about in the open. It lets a whitehat (greyhat?) like me see deeper into the brilliant minds of those who manipulate to achieve rankings – a fascinating pursuit.
