Which method is specifically used to determine the effectiveness of Internet ads?

• A. Click-through rate
• B. Pixels
• C. Conversion rate
• D. Engagement rate

Answer: (A)

This question is about measuring how well an online ad prompts people to take action. The best measure for that immediate response is click-through rate, which compares how many people click the ad to how many times the ad was shown (clicks divided by impressions). For example, 60 clicks from 1,000 impressions give a CTR of 6%. This metric directly shows how compelling the ad is at prompting action and is useful for comparing different ads, placements, or audiences in the same campaign.

Tracking pixels are pieces of code used to gather data on user behavior, but they aren’t a direct measure of how effective the ad is at generating clicks. Conversion rate looks at what happens after the click (like purchases or sign-ups), not the initial engagement with the ad. Engagement rate assesses broader interactions with content (likes, comments, shares) and doesn’t specifically quantify response to the ad itself.
