quick links require no increase in advertising costs is the transition to the link paid the same as one click on the ad. If the user when viewing the ad will click on a few links, you only pay for one click.

When you add quick links the price per click will decrease, as it increases the forecast of the CTR, and usually himself CTR, because the ad is more noticeable. And the higher the CTR, the lower the price per click.
