ethos (character) logos (reason) pathos (emotion)

Explanation:

Ethos is an appeal to credibility or character. The ad mentions "online reviewers love us," which is using the reputation and credibility of the reviewers (an external source) to persuade. Logos is appeal to logic (no data/statistics here). Pathos is appeal to emotion (no emotional language like joy/sadness). So it's ethos.

Answer:

ethos (character)
