How important are reviews for e-commerce products?
An in-depth look at how important are reviews for e-commerce products and what it means for your business. Full answer and strategy on the E-Commerce Marketing page.
On Amazon, reviews are a direct ranking signal. The A9 algorithm that determines search placement weighs conversion rate heavily, and conversion rate is directly correlated with review count and average star rating.
A product with 400 reviews at 4.3 stars will almost always outrank a competing product with 12 reviews at 4.8 stars because the volume of social proof converts more buyers.
Getting your first 50 reviews is the single most important milestone for a new Amazon product listing.
On Google Shopping, reviews do not affect your placement directly the way they do on Amazon. But they affect your conversion rate.
A Google Shopping ad that triggers a product page with zero reviews converts at a lower rate than one with 50 reviews, often significantly. The same buyer who found your product through Google Shopping is going to check reviews before purchasing.
If your product page has none, a percentage of those buyers will go back to Google and find someone who does.
The fastest legitimate way to increase Amazon reviews is through the Request a Review button in Seller Central, which sends an automated, Amazon-compliant review request to every buyer.
You can also enroll in Amazon Vine if your product is newer and you need initial review volume.
What you cannot do is offer incentives for reviews, selectively request reviews only from buyers you know are satisfied, or use third-party review services. These violate Amazon's policies and the risk of account suspension is real.
For your own website, a post-purchase email sequence requesting a review is the standard approach. Time it for 7 to 10 days after delivery when the product has been used but the purchase is still fresh. Tools like Klaviyo make this easy to automate.
Google reviews collected on your Google Business Profile also feed into Google Shopping rich snippets if your product reviews are structured correctly, giving you star ratings in the shopping ads themselves.
