One in five Google homepage views in the United States goes to iGoogle. You can post the “Add to Google” button on your website to urge visitors to add your choice content to iGoogle and see your items every time they visit the Google homepage.
The “Add to Google” button enables you to promote any content you choose, including interactive applications, feeds, and links to your own website, by making it easy for users to quickly add it to their iGoogle page. For as long as users keep your content on their iGoogle page, your items could appear to them each time they visit iGoogle. Active iGoogle users automatically see iGoogle each time they visit Google.com, so popular feeds/gadgets that link back to your website can drive lots of traffic back to you over time.
Use the form to create the HTML for your site. Be sure to go to the right section for either your feed or gadget. Simply enter the URL for your feed or gadget, click "Create HTML" and copy and paste the resulting text onto your website.
Additionally, if you would like to promote more than one gadget or feed, you can select the “Several” option. This option enables you to generate a new tab on iGoogle that will contain your gadgets and/or feeds.
Most blog hosting services make it easy to create a feed. Check those sites’ help content for more information (e.g. Blogger, LiveJournal, or Typepad). You can also create custom feeds using Google News and Google Groups. If you host your own website, there are a number of resources on the web to help you get started creating feeds, such as this guide by Danny Sullivan.
Most of the gadgets displayed in the Google Directory have thumbnails associated with them that illustrate what the gadget does. You can specify a thumbnail in your feed. The suggested dimensions for thumbnails are 120 pixels wide by 60 pixels high. Google downloads this image, scales it to 120x60, adds padding as necessary, and for performance and reliability, re-hosts the image on a google.com server.
The syntax can vary depending on the type of feed format you are using. Here's an example of how you might include thumbnail information in an RSS feed:
<!-- The title is used in various places in the directory and Personalized Homepage
to help users. Please keep the title as short as possible. -->
<!-- The link is used in the Personalized Homepage title-bar, to link to your site -->
<!-- The description is used in the detail page about your feed -->
<description>A nice long description of your feed.</description>
<!-- …other channel sub-elements may go here, e.g. ttl… -->
<!-- …other image sub-elements may go here, e.g. width… -->
<title>RSS Item title #1</title>
<!-- …other item sub-elements may go here, e.g. description… -->
<!-- …more items… -->
Here is an example for Atom:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<feed xmlns="http://purl.org/atom/ns#" version="0.3" xml:lang="en-US">
<title mode="escaped" type="text/html">Test feed</title>
<tagline mode="escaped" type="text/html">A nice long description of your feed.</tagline>
<!-- other feed sub-elements, including id, links, etc. -->
<!-- …item elements… -->
<!-- …other items… -->
