The Monthly Social Index Spotlight: Petco, PetSmart, Sprint, T-Mobile

Overall, the photos posted by Petco are of better quality than those shared by PetSmart. Within a day or two days of one another in March, each brand posted bunnies. They earned an equal number of comments, but the Petco photo had two times the number of "Likes" and four times as many shares. Furthermore, roughly three-quarters of Petco’s photos included a call to action (CTA). Comparatively, fewer than half of PetSmart’s photos contained a CTA.
