Ok i have a Campaign running at $20 a day and the bid on my keywords is 0.91 avg CPC is 0.74. What i would like to know is what can i do to gain more sales or lower the CPC price with out losing clicks? Once your Campaign is at this stage what do you usually do?
Track your conversions. Cut Words that are not converting. Have compelling ads, if you have good click-troughs and position placements you should be rewarded with a great quality score and lower click costs.
ya my ctr is doing really well for some of my keywords but how can i track which keywords are converting? since i am a affilite were do i need to place my code for tracking?
Depends on what network (if any) you are an affiliate of. If you have a affiliate manager, use "Conversion Tracking" within adwords and forward the code to them and they can place it for you. If you are promoting Clickbank or so you may ask the merchant himself, or use a program such as Prosper / Track 202.
You need your pixel placed on the thank you page if using google's conversion code or tracking 202. There are other programs out there that don't require this step.
