Optimization: Ad copy, landing page testing, keyword management. The best way to combat slipping conversion rates is to optimize the PPC campaign beyond bid management. Tactics like ad copy optimization and landing page optimization allow you to increase your average conversion rate; in some cases, even during steep budget increases. As a nice side benefit, your quality scores should improve and your average cost-per-click should decrease.
@samorvil Test, Test, Test, and oh yeah Test Sam, I hate to tell you this brother but there is only one way to optimize your advertsing campagins and that is to test, test, test, and test. I know that isn't the answer you are looking for but its true. You have to remember this buddy each and every niche has diffrent ROI some has way better some have far worse. If you lose money or do not see any positive return drop the campaign if you see return or have sales I would tweek it to make it more optimzed. I would also not target high end keywords rather keywords that are similar ( I know a lot of peole will be yelling at me for telling you that -- because it's a secret ) for example you can think about "weight lose" this is easily a buck fifty to god knows what. I would suggest trying the following keyword. "Counting Calories" obivously if someone is count calories they are worried about losing weight in which BINGO you have a cheaper keyphrase. ( I don't know about that excat one but you get my idea ) TEST TEST TEST AND TEST Good Luck Brother.
