AdWords Conversion Optimizer Criteria changed

Google adwords Conversion optimizer is now available to most of your campaigns. Now one can use adwords conversion optimizer to any campaign with atleast 50 conversions in last 30 days which was earlier 200. By doing so i think now there is chances to see the realibility and result of this conversion optimizer. Now more B to B sites and ecommerce sites will use this tool. As we know the conversion Optimizer uses our conversion tracking data to get more conversion at lower cost.
It achieves this by optimizing your placement in each ad auction to avoid unprofitable clicks and get you as many profitable clicks as possible.

So now if you are looking for more conversion at low cost then try conversion Optimizer even though you have very less(50) conversions.
