Item
Types on Google's review snippet page. For LocalBusiness and Organization Google asks for reviews that your site collects about other businesses, not about yourself (its guidelines on self-serving reviews).
One absolute URL per line. Google recommends several images with 16x9, 4x3 and 1x1 ratios.
Average rating
Use a dot as the decimal separator, 4.6 and not 4,6. The scale is 1 to 5 unless you set the limits below.
Google accepts ratingCount or reviewCount; this tool writes ratingCount, the form its examples use.
One review (optional)

What it checks and how it works
The tool follows Google Search Central's review snippet page, opened on 29 Oct 2026. For an aggregate rating it needs ratingValue and either ratingCount or reviewCount (this tool writes ratingCount), and recommends bestRating and worstRating. For a review it needs author and reviewRating.ratingValue, and recommends datePublished and the rating limits. The item must be one of the types Google lists, among them Book, Course, Event, LocalBusiness, Movie, Organization, Product, Recipe and SoftwareApplication.
Use a dot as the decimal separator (4.6, not 4,6). For LocalBusiness and Organization, Google says reviews are for sites that collect reviews about other businesses, not about themselves, under its self-serving reviews guidelines. The tool does not verify that the ratings are real or that they are visible on the page; Google's guidelines require both.
