I'm using Google rich snippets (https://developers.google.com/structured-data/rich-snippets/reviews) to tag ratings and reviews on this website: http://www.fwpest.com/
Google's Structured Data Testing Tool says "All good" here: https://developers.google.com/structured-data/testing-tool/?url=http://fwpest.com
But I don't see the stars below the website url on a Google SRP here: https://www.google.com/search?q=f%26w%20pest%20control
By contrast, I do see the star rating and review metadata displayed for the ContactUs and BBB pages.
Why stars for ContactUs and BBB pages but no stars for fwpest.com?
Google Search doesn’t seem to show Rich Snippets for homepages.
This is currently not documented, but confirmed by the Google employee @methode:
We (Google) don't accept rich snippets for homepages; rich snippet annotations should be placed on leaf pages.
