Well I must say adsense is the biggest platform to earn thousands of dollars but you need patience and hard work.although it is very easy to be a part of adsense and very easy to make an adsense account.if you wanna get paid you have to earn atleast $100.the features and functionality of adsense are very easy to use.but the main thing I dont like about adsense is that if your ctr is more than 20 or 25 percent adsense will block your account.thats why I dont like adsense although the service and support features of adsense are very good.this is my personal opinion about adsense.
