What You Need (And Don't Need) In Your Sidebar

One of the greatest things about WordPress (and some other blogging platforms) is the number of plugins available. One type of plugin is one that adds extra widgets and other things to the sidebar. Some of these can be helpful, like a latest comments plugin, or they can be completely useless, like a random quote plugin.

This post should cover some of the Do's and Don'ts of blog sidebars.

Search Box

A search box must be included in every site's sidebar. It's important that the user can search from any page of your site. If you don't want to put it in the sidebar, put it somewhere else, like in the header. If not in the sidebar or in the header, at least have it in the footer.

Page List

If you don't want to use a horizontal navigation bar, a list of pages in the sidebar can be used as long as the list does not go on for too long. The goal should be to keep each section of the sidebar small, so that there is room for each of the other sections.


Depending on the number of categories you have, a list of categories may be helpful, or it may ruin your entire site. Again, the goal should be to keep each section of the sidebar small.

Personally, I think that 10 categories should be the maximum number to have in a list. I have seen a blog with over 100 categories stretch a page with just a couple lines of content enough to make my scrollbar just a few pixels tall.


As we all know, it costs money to run a site, and one way of making money to pay the bills is through advertising. The sidebar is usually one of the most used places for ads. Of course, just make sure not to fill up your sidebar with too many ads, and make sure that they are as unobtrusive as possible.

Latest Comments

I think that a latest comments sidebar widget can be very helpful to find the latest discussions at your blog. You can display a few of your latest comments, with a combination of either a gravatar, post excerpt or a link to the author's homepage.

Latest Posts

A list with a few of your latest posts can be helpful to new visitors to your site, who may have stumbled across some of your older content. With your latest posts right in your sidebar, they can easily see what some of the latest things going on around your site are.

Other Things

I don't really think that there is much else that can go into a sidebar. (If you know of something else that would be helpful in a sidebar, let me know!) Unfortunately, there are some sidebar widgets that don't really help the user at all, like Flash games. (Trust me, I've seen those before.)


This is one that I see on a lot of blog sidebars. I don't think that a poll should be a part of a blog's sidebar. It just takes up extra space when the poll should really be part of a post.

Random Quotes

Something that I see less often that sidebar polls, but that I still see a lot, are random quote widgets. For some reason, WordPress even comes with the Hello Dolly random quote plugin. Please tell me if you can find a good use for displaying a randomized string in a sidebar.

So, is there anything else that you think belongs in a sidebar, or something that you don't like to see in a sidebar? Be sure to leave a comment.

    Subscription Box: A box giving options to subscribe should be there. It helps in building RSS readers.
    Recent Visitors: Honestly, I hate this! This widget does not deserve even a single pixel in sidebar!

    These are only ones that come to mind! And yes, last one, "Visitors Location", it's another useless widget!

    @Mr. I: Yeah. I really don't see the point of a "Visitors Location" widget. If you really need to know where your visitors are from, use some other tool, and don't display it publicly.

    Personally I never show my categories since I do not think they are useful for the visitor. I have never once used the categories to go through all the post on a specific blog.

    @Stefan: The only real reason I keep the categories in my sidebar is because the list isn't too long, and a few people actually click on them.

    If I end up having more than 10 categories, I will remove them from the sidebar.
