How to Make Money
If you search this on Google you will find a lot of different answers but in reality you need 3 things:
Any Website which is a part of Adsense program must meet adsense guidelines. Adsense has a number of policies related to website content, copyright laws, ad placement, traffic sources and many more. To make a career as an Adsense publisher and want to make money online, you need to make sure that you will never violate these rules.
Besides being compliant with adsense policies you need to have a lot of content published on your website. Although content can mean a number of things (videos, images, etc) what you need is original and unique TEXT content (blog posts, articles, how-to guides). Of course with the text you can have images and videos but text has to be the main part of the website.
To make money with Adsense a LOT of traffic is needed. In my opinion adsense is not suitable for websites that only receive a few hundreds of visits per day.
So, if you want to become a ‘professional’ adsense publisher you need a good website, a lot of original content and many people visiting your website on a daily basis.
