How do you guys generally a / b test your landing pages through Yahoo since they don't have the same feature as AdWords? Do you guys just duplicate the Ads and give them different urls or variables?
pretty much, but you can use Google Website Optimizer to run a simlpe A/B test for all traffic that comes to your site... Ben Attacat - ppc specialists
The Google Website Optimizer tests ALL traffic to the website (depending on the percentage of traffic you attribute - 100%, 50% etc). So if you are only testing landing pages (and not traffic sources or adverts) then the Website Optimizer can run a A/B test for all traffic to the site. You can also use Website Optimizer to test several different versions of the same page using A/B or multivariant testing of different page elements. The other option as you say is to duplicated the Yahoo! ads and just choose different landing pages - can be a hassle to analyse easily though.
