Recently I heard a lot of people were failed to get the adsense account where not like the old days where you just need to create a blogspot account, write certain articles and you are good to apply the accounts. If you still doing the same thing, I can guarantee that you cannot success anymore except you have a very good niche.
If you want to get some idea on how to get the adsense account then you need to have the following:
1) A decent website with at least 50 to 60 webpages before you can start to apply the adsense account
2) You need to have a term of use page
4) Valid contact method or valid email address if adsense want to contact you.
Hope all that success in adsense account. Thanks
