Correct answer is option 'C'. Can you explain this answer?
What is ad frequency?
a)
the total number of impressions your advertisement receives
b)
the total number of users who clicked on your advertisement
c)
the number of times a single user will see your advertisement
d)
the number of visitors who completed the checkout process

Rajeev Sen answered |
Ad frequency refers to the number of times a single user will see your advertisement. This means that if a user sees your advertisement three times in a week, the ad frequency for that user is 3.
Ad frequency is an important factor to consider when creating and managing an advertising campaign. If the ad frequency is too low, it may be difficult to effectively reach and engage your target audience. On the other hand, if the ad frequency is too high, it can lead to ad fatigue, where users become annoyed or annoyed by seeing the same advertisement repeatedly and may tune out or avoid the advertisement altogether.
In general, it's important to find a balance when it comes to ad frequency. This may involve adjusting the targeting of your ads or the frequency with which they are shown to different users. By carefully managing ad frequency, you can ensure that your ads are effectively reaching and engaging your target audience without causing annoyance or fatigue.
So, Option c is correct answer.
