If someone has a product/web site and he wants to play on to many keywords, which i believe most people want to do, how do he optimize his web site for all these keywords.
If you don't have have the ad-keywords in your web site then your quality score will be lower and consequently cpc will be higher.
Now it is not possible for the advertisers to stuff too many keywords on the landing page neither they can make a lot of landing pages for selling the same thing.
What should be done in this case. Does anybody has any idea ?
