Proof of Usefulness Score

You're In Business

Shop Sheriff is a verifiable, highly-rated Shopify app development agency. Their flagship 'AMP' app has over 500 5-star reviews and significant adoption in the Shopify ecosystem. However, the project faces market headwinds as Google's AMP technology is largely deprecated in favor of Core Web Vitals. The PoU score is heavily penalized by the extremely low quality of the submission (lazy, sarcastic responses) and the 'everyone' reach claim, though verified traction rescues the score from zero.
