Most of us know how hard it is, to get an adsense approval message, not to talk of getting it with a .tk domain, according to adsense guidelines, they need top-level domains like .com, .net, .org and not free domains like .tk, why they accepted it, i don't know, but i will share you the tips i used in getting my approval... now let's get started

Prior to my adsense approval, i have been rejected thrice after application submissions, before i got my approval message....

Approval Tips
* Have at least 8 unique contents on your homepage
* Have links like privacy policy, about us, terms of use
* Have a simple template design
* Have a nice pages/links navigation on your blog
* Due to the fact that adsense i got adsense approval with a .tk domain, you can get approval with any domain name, as long as it is not a sub-domain
* If you are using "blogger platform" , don't upload 'stupid' templates, like dens template, harmonia, and their likes, if you are using self-hosted wordpress, then carrignton mobile will be the best for adsense approval
