Footprint Finding problem

How to find Magento sites ? 

If there is a footprint for google search. ...

I can't find Footprint for magento..

if  is this  possible , 

than  please  give me any tips ...

What should this be useful for? There is no engine for this type of site and I don't see how to place a link on them anyway.

i don't know whats that platform is about but i've just take a quick look into their front end demo.

take this footprint and go from there:
