The invisible reviews problem
Verity Score verifies that your customer reviews are machine-readable. Specifically, we check for an AggregateRating schema in the HTML source of your product pages.
Why it matters for AI
Customer reviews are one of the most powerful trust signals for AI shopping agents. A product with 342 reviews and a 4.7/5 rating will be recommended before a product with no reviews.
Research from Yale University, Columbia University, and the University of Chicago shows that AI agents are 20–40% less likely to select products when sentiment data and review volume are missing. Without AggregateRating in the HTML, you’re effectively invisible to this growing share of the buying journey.
But here’s the catch: most Shopify review apps load reviews via JavaScript. The widget displays beautiful stars for human users, but the HTML source contains nothing. AI crawlers (GPTBot, PerplexityBot, ClaudeBot) don’t execute JavaScript - they only read the initial server-rendered HTML.
The Simple Test
- Go to a product page on your store
- Right-click → “View page source”
- Ctrl+F → search for
AggregateRatingorratingValue - If you find nothing, your reviews are invisible to AI
The Key Point: HTML vs JavaScript
The fundamental question is simple: are your reviews in the HTML source or loaded via JavaScript?
A widget that displays beautiful stars but whose data is not in the HTML source is invisible to AI agents. This is the most common problem on Shopify stores.
Verity Score automatically detects whether your AggregateRating is present in the HTML and whether the values are consistent with what is displayed visually.
