This update changes the way Google's algorithm ranks product reviews on different sites, focusing on rewarding high-quality product reviews which go in-depth and contain supporting files such as Images or videos. This is the fourth Google Product Reviews update released and It should take 2-3 weeks to complete the update.

Google has given some tips to help shoppers discover your reviews, those of which being:

• Evaluate the product from a user’s perspective
• Demonstrate that you are knowledgeable about the products reviewed. It could help to use expert terminology (e.g. if you are writing a product review for a washing machine then it will help to mention the strengths and weaknesses of each feature)
• Provide evidence such as visuals, audio, or other links of your own experience with the product. This is to support your expertise and reinforce the authenticity of your review.
• Share quantitative measurements about how a product measures up in various categories of performance.

• Explain what sets a product apart from its competitors
• Cover comparable products to consider, or explain which products might be best for certain uses or circumstances.
• Discuss the benefits and drawbacks of a particular product based on your own original research
• Describe how a product has evolved from previous models or releases to provide improvements, address issues or otherwise help users in making a purchase decision.
• Identify key decision-making factors for the product’s category and how the product performs in those areas (for example, a car review might determine that fuel economy, safety and handling are key decision-making factors and rate performance in those areas)
• Describe key choices in how a product has been designed and their effect on the users beyond what the manufacturer says.
• Include links to other useful resources (your own or from other sites) to help a reader make a decision.
• Consider including links to multiple sellers to give the reader the option to purchase from their merchant of choice.
• When recommending a product at the best overall or the best for a certain purpose, include why you consider that product is the best, with first-hand supporting evidence.
• Ensure there is enough useful content in your ranked lists for them to stand on their own, even if you choose to write separate in-depth single product reviews for each recommended product.

This update should not affect websites but when you look at your google reviews you should find that higher-quality reviews which can provide more information for a user will be shown first. This is great as it means people looking for a product will be able to get more information from reviews.
