Unlike many of the free blogging services, we not only allow you to place ads and make money with your blog, we strongly encourage it!
The amount and type of income that you make from your blog will depend on how you choose to monetize it and how hard you work to build your audience.
There are many ways to do this.
Direct advertisers - banners, text ads, and paid reviews just to name a few
Direct Affiliate marketing of a specific product
Affiliate marketing through a network like ClickBank.com or Amazon.com
Ad networks like Google Adsense
Selling your own products and services
We cover some of the easiest ways to get started making money with your blog in the Blogging Basics Training Course: https://theblogpress.com/build-blog-website-wordpress/.
How long this takes depends on you and what your expectations are. At a minimum, if you follow the detailed plan and do ALL of the items that we show you how to do, then you should at least be covering your blog hosting costs within the first 90-days. I can't guarantee this, because it really does depend on you and the effort and time you are willing to dedicate to it.
Blogging is not a get rich quick scheme as many will have you believe, but it is possible to generate a 6 figure income from blogging - we do. But it took us 3 years of consistent effort to get there.
I cannot tell you how long it will take you to get there, but if you're willing to learn and work, and NEVER quit, then it is possible for you.
