Before internet existed, people asked neighbors, family, or friends for advice before buying a new washing machine or trying a new brand of coffee. Today, product reviews are digital version of that friendly advice. They are written comments, ratings, and photos left by real people who already bought and used a specific item from an online store.

Most review sections use a simple five-star rating system, where five stars means excellent and one star means terrible. Shoppers can quickly look at average score to see if an item is high quality. Reading text of reviews gives even more detail. Buyers often share helpful tips, like whether clothing runs too small, if a toy is durable enough for kids, or if colors match website photos exactly.

For shoppers, these reviews provide honest feedback. People trust opinions of regular customers far more than beautiful descriptions written by marketing teams. It gives buyers peace of mind and reduces fear of wasting money on a bad product.

For online store owners, reviews are incredibly valuable. Positive feedback acts as free advertising that convinces hesitant shoppers to hit buy button. Even negative reviews help because they show where products or descriptions need improvement. Furthermore, search engines like Google love fresh content, so when customers write new reviews, it actually helps online store appear higher in search results.
