Yahoo Conversion Counter
Conversion Counter is the Yahoo! Search Marketing free, conversion tracking tool. Conversion Counter tracks the number of conversions (such as sales, registrations, newsletter sign-ups, etc.) generated by your Yahoo! listings.
Conversion Counter tracks conversions for your overall account, as well as for each keyword and match type. By tracking your results, you will be able to evaluate the effectiveness of your budget and understand how your clicks translate into sales and/or conversions. You will gain insight into the performance of your account as a whole, as well as the performance of each individual keyword and match type. Having this information will allow you to optimize your listings and get the most out of your account.
When an Internet user clicks on one of your listings and arrives at your Web site, Conversion Counter places a "cookie" on that visitor's browser. When the visitor reaches your transaction completion page (i.e. your sales confirmation or sign-up page), Conversion Counter registers a conversion and ties it to the visitor's previous search. The cookie used by Conversion Counter is active for 30 days, so you will be able to track conversions even if your site's visitors do not convert right away.
Getting started with Conversion Counter is free. You or your Webmaster simply copy and paste a piece of HTML code onto one page of your Web site (usually the sales or sign-up confirmation page). To sign up for Conversion Counter, sign up for a Yahoo account and go to the Account Set-Up page.
