I assume the Google Slap you are referring to is the “Bridge Page” crackdown Google has done recently. This mostly just affects folks that were doing affiliate marketing. It seems that many affiliate managers do not allow or provide a link to their checkout page and this forces advertisers to build what Google classifies as a “bridge Page” which is prohibited under policies.
If you follow policies and guidelines you will not have an issue. The problem with affiliate marketing is that you often do not control the landing page content. If you are not able to link directly to the checkout page, you become liable for anything the affiliate puts on their landing page. This makes it awkward for both the affiliate marketer and the merchant since they must trust each other and suffer equally in the consequences of the other parties’ behavior.
