A niche blog can be advertised in a magazine or a newspaper esier than a normal blog. The reason for this is once again because the focus. Lets say you have a blog about cars. its easier to make a ad and get advertisers as well as drawing people to your site via magazine or paper. Usually people buy magazines of things they have interest in and anything that has not to do with that magazine topic they reallly dont want while reading that specific magazine.
But when you advertise your niche blog in a magazine that has to do with the same topic, that is when you will get the attention of those readers and potentially get more visitors to your site.
