The plugin options are relatively limited — you can choose what “rel” attribute you include with the link (the default is “nofollow”) and you can choose to display the button before or after your post content. You can also specify the icon’s height and width. Making some changes to your WordPress theme’s CSS options, you could further customize the appearance of the button, but as it stands, it’s a pretty basic (and easy) way to add a Buzz button. If you want to add Buzz manually to only certain posts, there is a template tag that you can add to those posts.

WP Google-buzz

Another button plugin option is WP Google-buzz from Arpit Shah. This button is extremely similar to the Google Buzz Button plugin, but it adds a few more options. You can choose to show the button before or after content or to add it to posts manually, but there are also options for what style button you want to use. Depending on how you have your blog setup, you might want to use a different size or style of button.

WPBuzzer

Hameedulah’s WPBuzzer is the most robust of the Google Buzz button plugins as of right now. The style of the button is almost identical to what the Google Buzz Button use (albeit, not quite as clean), but the options are where this plugin really shines.

You can choose where you want your buttons to appear (on posts, on pages, on the home page, in your RSS feed), whether your want the button to appear before or after the post, the target for the button (a new window or a pop-up share option) and even the CSS style. You can also choose to use a small or large button.

The biggest feature is that you can track share counts (just like we do at Mashable) if you have a Bit.ly API key and login.

Light Social

The Light Social plugin takes a slightly different approach to the Google Buzz button. Light Social is a plugin that inserts a set of social share links at the bottom of each of your WordPress posts. This way links toDigg, Reddit, Facebook, LinkedIn and Twitter are all automatically at the bottom of the post. The developer of Light Social updated the plugin to include a Google Buzz icon and share link as well. If you want to add lots of social options to your posts — Light Social is a good approach.

Buzz Your Comments

There are a number of different all-inclusive comment solutions for WordPress — there’s Echo, Disqus(which we use here at Mashable) and IntenseDebate. IntenseDebate is owned by Automattic, the people behind WordPress.com and some of the main contributors to the WordPress.org project. So it probably shouldn’t be a surprise that it’s the first of the solutions to offer Buzz integration into its service.

If you use IntenseDebate on your blog, you can now easily add a Buzz It button to the top of your comment form. This won’t let people Buzz their own comments (we expect something like that will come in the future), but it adds another “Share on Buzz” option for your post to your visitors. If you use IntenseDebate, you can activate the Google Buzz This plugin by enabling it in the Plugins Directory.
