There have been many movements in the blogosphere over the past year, but one that I haven’t fully ever understood is the recent transition blog sidebars have been making to the footer of the blog.

I originally noticed this probably 6-8 months ago when a few well made WordPress themes were released and started making their way around the blogosphere. At the time, I didn’t think much of it because they were fairly uncommon and they weren’t being used by full time bloggers. Since then, I’ve noticed an explosion in this type of theme’s popularity. The first full time blogger’s site I noticed it as was Ryan and Ashley’s redesign at CyberNet News , where they added a new custom made theme using various sidebar functions in the footer. Next Darren at ProBlogger released a custom theme, and today even John Chow has started using a custom theme that has various sidebar functions moved to the footer of the blog. I don’t believe any of the 3 had any modules/widgets in their footer’s prior to the site redesigns, so I can’t help but wonder what made them switch to this type of design.

What are the advantages to making this switch? The first and most obvious advantage to this type of redesign would have to be the space this makes available in your sidebar for advertising and affiliate links, which can help you make more money online with your website. The other advantage is that the footer is usually the last part of the page to load, so any hangups with your MyBlogLog widget or slow loading modules would be less noticeable by a reader when placed in the footer.

What are the disadvantages? Placing things in your blog’s footer makes them less likely to be seen. This means you would ideally want to place only things that aren’t essential to your blog’s success, such as your blog categories/archives, recent posts/comments, or extra fluff that is just for fun (like the MyBlogLog widget and Alexa widget). I am also not a big fan of the look it gives the blog, but I suppose it will grow on me as I get more used to it.

Overall, I can see reasons for using and not using this type of theme, but I just found it curious that so many full time bloggers have made the switch to this type of theme all around the same time.

What are some of the advantages/disadvantages I have missed?
