An interesting question, what is the aim of your blog? Are you blogging just because you like to write? Many people are. They love to write and want to let everyone know how much they know about a subject. It may that they want to share their passion, a hobby or knowledge and experience they have in a particular field. Sometimes they want to review things and let you know what their opinion is of those things. They enjoy picking something up, testing it out and sharing their results. And sometimes they just want to get all thier thoughts and feelings down on paper in a public forum, and a blog is indeed a very good way to do this.
Others start a blog because they want to earn some money from it. Again it could be your blog focusses on something you know a lot more than most about, a hobby or passion you have and you can share your very personal experience and knowledge of that subject. Other bloggers want to review things, they love to bring to the reader an independant review of something for sale on the open market.
Both of these avenues give good opportunities to make money from your blog. In the first instance you could write a report to sell on your blog, one that is related to the subject of your blog but that expands the knowledge of the reader further than your blog posts do. Give them more in the report you are selling than you do in your posts and let them know that there is much more information to be had if they buy the report.
Review sites are also a great idea to encourage sales. You buy the product (or if you are very lucky you can get a review copy without having to pay), you test it out, maybe make a video of your findings, then put an affiliate link to the product in your review. Even if the product is a physical product you can still add affiliate links from Amazon and earn some commission, although downloadable products will make a higher rate of commission for you. Amazon is notorious for paying quite small percentages in commission.
So there are two very quick and easy ideas for blogs that can earn you money. Of course if you are looking to monetise your blog don’t forget to sign up for Google Adsense or another automatic advertising product. I use Adsense and I also use Clickbank Ad Rotator, which has both a free and a paid version. The paid version can be completely customised so is by far the better option in my opinion.
It is very important for you to be clear with yourself about what the aim of your blog is. If it is to earn money from then make sure you incorporate all of the money making techniques you know of into your blog, otherwise you could be missing out on some lucrative income streams.
