Why can’t I see my ads?

Your ad is shown only on portal pages whose address contains every word of one of your keyword lines, and only while the campaign is approved, switched on in Campaigns, and has balance and daily budget left. When several campaigns match the same page they take turns, so one visit may show another advertiser.

Check the campaign's Status and ON/OFF switch in Campaigns, your Ad Balance in Transactions, and open a portal search for the place your keywords name to see a page that matches.
