This is my project I made. http://www.binarydecimal.com/ I just don't know is google gonna banns me or it will index. I was inspired by this website http://www.hexadecimalnumbers.com/ I saw this website has about 40-50 milions of indexed links and it using Adsense... But I made my website faster, better look, more links, better links hierarchy, canonical, better internal linking and more number systems. Also made sitemaps "addon" So here is a example of number 100 (decimal) converted to all other number systems (from binary to base36) http://www.binarydecimal.com/100-decimal/ I think this can be useful. I just don't know what do you think - Will google ban this website after a while??? Can I use Adsense on it?
