Having a blog is a great thing: you can promote your products and services and get a lot of attention for your business; you can promote your work, whether as a painter, photographer, or writer, and maybe even get a job related to the things that you love; or you can simply express yourself and even update your relatives and friends on the goings-on in your life, which can be great if you live in a faraway place and cannot update your relatives and friends more than once.
However, a blog can also be a good way for you to earn money, over and above mere expression and promotion.
Thanks to a lot of different online money-earning methods, you can earn commissions when visitors go to your blog. For instance, you can put up advertisements on your site through an affiliate network or through an advertising program. If one of your visitors clicks on your ads, then you get commissions. The ads are tailored to fit the contents of your website, and they are made so that your visitors will most likely be interested in them and thereby click on them. Therefore, you need to have good website content, as this is what the ad companies need in order to know what kind of ads to place on your site.
Moreover, the more visitors you have, the greater the chance that someone will click on your ads and that you will get commissions.
This means that you need to invite more and more people to your blog, and not just to get money, but to get attention. After all, if your blog is interesting enough, you may get a lot of people linking to you. One way that you can promote your blog is through posting on forums.
