“Objects” are a term derived from web design talk for code that is added to your site to create a unique function. A good example is a web counter, which tells you how many people have visited your site.
A more sophisticated site object would be an RSS feed, which allows you to access news feed from another source. The idea is you cut and paste the code into your site and the information changes on a day-to-day basis as it is fed to one of your blog pages. An RSS feed is a useful thing to have on your site as it can link your reactions to current events and news to the original articles. It is also a good idea to have other people link to your RSS feed through a blog.
Another common object is a web ring or blogging form. This is a cheap way to draw traffic to your site. You simply join a ring of sites that have topics similar to yours and when people surf they have the option of clicking through a series of related blogs to get as much information about their site as possible.
As a rule of thumb it is best to put objects that directly relate to your site’s theme at the top of the blog and more utilitarian objects at the bottom. For instance if you have a list of objects that have sent you a number of links but they are not affiliates then you should put them closer to the bottom of the page. Something like a web counter with a high number of visitors on it is best placed at the top of the page as it can convince your readers that others enjoy reading your column too. It can also help convince bigger sites to link with you as well.
