I've read that AdWords instituted a new policy for destination and display URLs on April 1, 2008. What do I need to do to make sure I don't violate the policy and have my ads pulled?

Google did recently update their URL policy. The changes took effect on April 1, 2008.

The following can be found on the Inside AdWords blog:

"....... we have made the decision to no longer allow certain exceptions with regards to our display URL policy. This includes, but is not limited to redirects and vanity URLs. This policy will be strictly enforced regardless of past approvals and will apply to all advertisers, beginning on April 1st.

In line with our existing policy, we will continue to require that your ad's display URL match its destination URL (the URL of your landing page).

For example, if your destination URL is www.google.com, your display URL must also be www.google.com. The following would not be acceptable display URLs for an ad for www.google.com:

• www.google.co.uk - because this URL leads to a different site
• www.gogle.com - even though this URL simply redirects to www.google.com it is still not acceptable
• www.gooogle.com - because this URL leads to a page showing content identical to www.google.com"
