The policy at Google may not be changing regarding how they treat Display URL’s within AdWords accounts, but they are cracking down on those abusing the system. Effective April 1st of this year the display URL policy will be strictly enforced.
While the policy is relatively simple, some advertisers have found ways to abuse the system and in the light of some advertiser complaints, Google has decided to put its foot down in the act of fairness.
Barry Schwartz over at Search Engine Land has written on this in more detail and has given a few examples of acceptable and unacceptable Display URL’s, but in short, if your Display URL’s coincide with your landing page, you should have nothing to worry about.
