Social Media Advertising Research & Evidence-Based Practice 4

Question 1

Which platform-native tool is primarily used for measuring incremental reach and conversion lift on Facebook campaigns?

Accepted Answer

Facebook Conversion Lift Study

Answer

Facebook's Conversion Lift Study compares outcomes between exposed and holdout groups to measure true incremental impact.

Question 2

An ad researcher wants to avoid 'peeking' at results too early during an A/B test. Why is this problematic?

Accepted Answer

It inflates statistical significance leading to false positives

Answer

Stopping a test early based on interim results inflates the Type I error rate, increasing the chance of declaring a winner that doesn't exist.

Question 3

What is the key difference between reach and impressions in social media ad measurement?

Accepted Answer

Reach counts unique users; impressions count total ad displays

Answer

Reach refers to the number of unique individuals who saw an ad, while impressions count the total number of times the ad was displayed.

Question 4

A researcher discovers that users who saw an ad three or more times were less likely to convert than those who saw it once. This finding relates to:

Accepted Answer

Ad fatigue and frequency effects

Answer

Declining conversion rates with increasing frequency indicate ad fatigue, a well-documented phenomenon in social advertising research.

Question 5

In social media advertising research, what does 'incrementality' measure?

Accepted Answer

The additional conversions caused solely by the ad, beyond what would have happened organically

Answer

Incrementality isolates the true causal effect of advertising by comparing outcomes to what would have occurred without the campaign.
