Nearly two years ago we introduced seller rating extensions. In addition to helping users identify highly recommended advertisers, seller rating extensions often provide a CTR lift to sellers who consistently deliver a positive online experience.

Today, we’re announcing a change to help keep ratings fresh and relevant. Previously, we would show seller rating extensions only for advertisers that have at least 30 lifetime reviews and a 4-star average. Moving forward, we will only show seller rating extensions for advertisers that have at least 30 reviews over the last 12 months and a 4-star average.

Since customer opinions about a business can evolve over time, this change will help make seller rating extensions more useful and relevant for searchers. It should also benefit businesses that satisfy customers and garner positive reviews on an ongoing basis.
