Back in May, we launched our new and improved referral buttons. Now these new buttons are available for additional products and languages. You can choose from several different colors and options, and the buttons are in a sleeker, web-friendly GIF format -- all the better to blend in with your site.

Publishers have found that it’s most beneficial to place referrals where they're relevant. Do you run a photo blog? Try using a Picasa referral button. Looking to boost revenue for your web hosting site? Implement a Firefox referral button and watch your earnings grow.

Don’t forget you can also implement referrals in a text link format. Text links easily integrate into your site and often convert better than buttons. Here are a few tips on generating more revenue with text links:
  • You can endorse products you've enjoyed using and encourage your users to do the same.
  • Use text links to integrate the ad more seamlessly within your site content.
  • Try having the text links inherit the font and look of your site, so they fit in with your current text style and size.

If you’re not already displaying referrals on your site, you may be missing out! Publishers have let us know that they’ve seen an increase in earnings since they implemented the feature. One publisher with a history-related site told us, “I get 3,000 uniques a day, and was only making about $15/day with regular AdSense for content. Today, I tried Firefox referrals and beside my regular site income, I've already made an extra $17.20 -- and the day isn't over yet.”

Not only will you benefit from the extra earnings, but your users will learn more about other products such as Picasa, Firefox, and AdWords. To begin displaying the new referral buttons, simply choose Referrals from the AdSense Setup page of your account, then select the product you'd like to refer users to on your pages.
