It’s 11:30 p.m. After several last-minute targeting changes, your Google Display Network campaign is almost ready. You’ve set the targeting, and you’ve segmented out everything that needs to be segmented (of which there was a lot). Now all that’s left is uploading the ads so that they will start running at midnight as planned. All that’s left is adding the creative into the AdWords interface.
OH GOD NO.
AdWords just rejected your ads.
Your HTML5 ad is missing a primary .HTML file. Primary .HTML files include an Ad Size tag such as <meta name=”ad.size” content=”width=300,height=250″>. Make sure there is an .HTML file with an ad size tag in your HTML5 ad, and try again.
Now what? You’ve got 30 minutes to fix this, and both your designer and your developer left town for Vegas about two hours ago.
