Just got word from Yahoo! Search Marketing that they have lowered the minimum deposit requirement for all new accounts. Instead of $30 to start you can now get setup and the traffic flowing for $5. This should probably help some mom and pop type businesses with a low budget get setup without too much risk.
According to the Yahoo Search Blog:
As you may remember, back in October, Yahoo! Search Marketing eliminated the minimum spending requirement for US advertisers' sponsored search campaigns. Now we've taken one more step to making advertising with Yahoo! easier and more convenient - we lowered the minimum deposit from $30 to $5 for US advertisers.
That means now is a great time to get started with Yahoo! Sponsored Search and join a growing network of more than 100,000 advertisers. You can start with a deposit of as little as $5 and use it to pay for the click-through charges for your campaigns. After your initial deposit, you spend as much or as little as you like each month based on the keywords you select and how much you bid for each one. Through Yahoo! Search Marketing, advertisers can reach over 8o% of users online for as little as 10 cents per click. And of course, with Yahoo! an advertiser pays only when a user clicks.
I asked Yahoo about whether coupons or promotions still apply for this new minimum deposit and when I hear back I will post here the answer. Offically they have told me " coupons can be used on top of the deposit but not in lieu of it." Yahoo has some promo codes that you can use to get $25 self serve or $50 fast track back on starting a campaign. Just plug in promo code: USCJ11 and you are on your way to getting some free credits. According to this page, the answer is yes, discounts and promos still apply for the new min. deposit amount.
