A gravatar, or globally recognized avatar, is quite simply an 80×80 pixel avatar image that follows you from weblog to weblog appearing beside your name when you comment on gravatar enabled sites. Avatars help identify your posts on web forums, so why not on weblogs?

Setting up gravatars on your weblog is easy, you don’t even need an account! Plugins are available for leading weblog software, and our tutorials will have you running gravatars in no time. To request a gravatar from our servers, you simply add an image to your comments area with an “src” attribute that points to our gravatar image generator and includes an MD5 hash of the commenter’s email address. Since all gravatars are rated with an MPAA style rating, you can restrict your site to show only gravatars whose content you are comfortable with.

Here is a list of the most important on-page ranking factors and how they are addressed by this All in One SEO plugin. You might want to visit Options – All in One SEO to tweak the default options.

Titles

The text that you see in your browser’s window bar is the most important thing *on* your page. Make sure your titles are getting rewritten and the important stuff (your post titles) always come before anything else. You can leave a few words from your blog title to do some branding but don’t overdo. If your post titles don’t contain your most precious phrases you want to rank for then tweak them. Leave the post titles as it is but change the meta title.

Descriptions

Once your pages rank in search engines your description (aside of course from your title) makes a potential visitor want to click through, or not. It’s mta descriptions, believed dead by many people, that decide over your site’s fate. If you don’t want to invest the time and write a description for every post at least let them be auto-generated. This vastly better than the usual “Share This … Posted on … under …” description that is often used. If a post has an excerpt it is used, but not if you specify an explicit description.

Keywords

All in One SEO Pack can generate them from your categories (this was the old way of tagging your posts in wordpress) or from Ultimate Tag Warrior or, starting with Wordpress 2.3, the built-in tagging system. Using your categories is optional, the rest is auto-detected and used if there.

Duplicate Content

You can have “noindex” and the like generated for archive-, category- and tag pages if you seem to have trouble with duplicate content.

Democracy adds polling functionality to your WordPress blog. It grew out of frustration with the only other WordPress polling option, WP-poll. It didn’t have valid markup, it was clunky, and it required one heck of an installation process. So Andrew decided to create my own, using WP-poll as a reference. This plugin uses AJAX for quick sending and loading of poll data, although it doesn’t depend on javascript to function. It is fully functional in non-javascript environments, meaning it will work in ALL browsers. The AJAX part is tested to work in Safari, Opera, Firefox, and IE6/Win.

It also has a full-featured admin panel, which allows one to manage their polls. You can activate, edit, delete, and add new polls from the admin panel. It is also harder to ballot-stuff than WP-poll. It uses cookies as well as IP logging to prevent users from working spamming the ballot box.
