Creating a custom button for your blog to be used on the Google Toolbar is a great way to promote your blog. Once installed, the button can act as a graphical bookmark to your site. You and your readers can search your site using the search bar in the Google toolbar, without having to be on your site. In fact, you can highlight any text on any web page, click on your custom icon in the browser, and you will perform a search the text you just highlighted on your blog. The custom button can even list your last several entries, with data pulled from your feed.
