It really does not matter if you own a business or are just considering starting to make some money online.
In both circumstances you really should have a blog where you can bring in free traffic and then sell them your product or service or as an affiliate.
The process is very simple these days and there are many free blogging solutions such as WordPress.
You can set up the blog on your own domain for free and then add some relevant posts to it.
Be sure to provide interesting and valuable content as this is what will bring people back to your site.
In order to bring in some traffic you can submit your posts to social bookmarking sites where thousands of visitors can have access to your posts.
This is very easy to do and there are lists of these sites available across the web.
Another thing to do is to create some videos where you discuss the article you have written.
Video sites again get a huge amount of traffic daily and you can get a small amount of thins directly to your site.
You will need to make sure you are optimizing the site so that each visitor has the option of signing up to your list or purchasing your product.
Make sure that you have a good sales funnel in place otherwise you will be wasting any traffic that finds its way to your blog.
Finally, make sure you continue to give great information to your subscribers who will value this and remain loyal.
If you can consistently deliver then you can have a strong customer list who will buy from you again in the future.
