Google On How To Avoid AdWords Ad Disapproval

Google AdWords support representative, Charvi, said in a Google AdWords Help thread some tips on how to avoid AdWords ad disapprovals.

Google offered four tips and posted two videos with advice on this topic.

Here are the four tips:

• Your ad should lead to a website that works for all users regardless of browser, location or device
• Your ad can't lead to a website that’s under construction or an error page
• Your landing page's domain must match the domain of your ad's display URL; For e.g., if the website you're advertising uses "example.com," your display URL must also contain "example.com"
• Each Ad Group can have only one Display URL Domain

Here are those two videos:
