Bidding Strategy Tips:

  • Create conversion rules for each step of your funnel: landing page, click to second page, add to cart, checkout, purchase, etc
  • Create custom audiences based on conversion steps using Include and Exclude
  • Age & Gender targeting that is not “All” only shows ads to logged in Yahoo users (Mail, Fantasy Sports, Finance Portfolio, etc)
  • Start a campaign with strict targeting, after a few days if you have a good CTR, expand the targeting
  • You might start with Women age 40-49, then a week later change to all ages and gender to get more impressions
