In order to make blogs such as WordPress popular, it must offer its readers good content. But apart from that WordPress bloggers need to make sure that their blogs are attractive as well. Each should look nice and appropriate for the purpose of blog and for its target audience.
What typically dictates the look of a WordPress blog is the WordPress Skin that the blogger uses. There are so many WordPress skins available on the WordPress site. A blogger only has to choose the WordPress skin that catches his attention and use it on his blog. There are also so many other sites that offer WordPress skins for free and for sale. Some would design their own WordPress skin as well.
Again, the look of the blog can make or break a blog. A blog should look nice because it is what readers see first. A boring looking blog will be ignored right away. People will click away from the blog immediately if the blog looks dry and ugly. That is why the blogger should choose the best WordPress skin for his blog. It should be something that would interest the people who will likely be interested on his blog.
The WordPress skin should capture the attention of its target audience right away. This way people will stay and read the blogs. If the blogger is trying to sell or promote something, he will always have a chance to explain the products and services that he is offering. Readers will not click away from the page but instead read what the blogger has to say.
