Why did advertising campaigns stop working?

Question

Google Ads

Hello, I can't figure out why the ad campaigns stopped working. Yesterday everything worked, it was the display network, and video advertising campaigns. Are there no shows today?

Answer 1

There can be many reasons, study the account in more detail.
1. Is everything okay with budgets? Are there any remaining campaigns?
2. What is the status of ads? Maybe they are rejected? Or under consideration?
3. What is the subject of advertising? Doesn't it belong to the prohibited ones? Competitors may complain.
4. Have you stopped requests in groups or other targeting?
5. What is the rate in groups? Have you changed it?
6. What strategy does the advertising campaign follow? If it is based on conversions and their cost, and there are practically none, then impressions can be reduced.
7. Did you add any words, platforms, audiences to exceptions?
8. Have you added adjustments for devices, locations, audiences?
9. Have the show times changed?
10. Is the landing page blocked or disapproved?
If at first glance there are no reasons for the lack of impressions, then take a look at the history of changes on the account for the last few days, including those preceding this situation. If nothing could be found, call technical support.

Answer 2

Because scripts.js is included before elements with class "hot" are created. Accordingly, elements.length is equal to zero, and the condition is false.
Wrap the code in scripts.js in window.onload, or include it below.
