I have problem happen recently to adwords when my credit expired something happen to account and after finishes the payment and add new credit card, there is no Impr. as I paid upfront payment and the account dose not work anymore as usual, i have change few setting even change the budget even more but same, I am not sure what's wrong there, not sure why but I guess adwords change some policy there, and makes it harder for advertisers .. ! I find out something about keywords that isn't trigger the ads I am not sure about this but same text advertisements were running before with no problems.. I rollover some keywords and this appear to me :
Your quality score is too low that;s why is not showing. The KW phrase does not trigger any of your ad- basically it means that your KW is not in your ad or landing pages. For example, if your selling travel business, your ad has to have the KW travel or your landing pages. Otherwise, your QS wil be too low and your ad will not show. Make sure the KW is in your ad and landing pages.
I see that the quality score is low and I agree with fong47. Also when you move your mouse over "No" you will see other reasons which might give you a little insight of what's going on. You also can do a keyword diagnosis in adwords to give you a more detailed overview of why your ads are not showing. For the rest fong47 is absolutely correct about relevancy. Landing pages and ad text should have your keywords that you are targeting; however if you have a huge list of keywords; group them together, put them in different campaigns and adgroups and then target them with multiple ads. Makes your life easier to match the landing page and ad text. Perhaps you will need more landing pages for the keywords list that you are targeting. The point is keywords in your landing page and ad text that closely match give you a higher QS with lesser cost on CPC as well.
Yes, but it should be appear in the network of websites, this prevent it to appear in search engine of google, but should appear in the network sites, right ?
Actually this applies everywhere whether its the display network or the search engine. You have to understand Google is about relevancy and user experience, it would not show an ad that fulfils QS for search engines. Although yes QS has nothing to do with the display network it wont be able to tell where to show it due to poor quality in the first place.
Your quality score is only 3/10 . It's not enough to display your ads. You should refine your keywords list, change your langding page content intend to customer and put those keywords reasonably. Finally, set your CPC more than usual and see how your ads act in the next 3 days.
