Top10.com Total Score
Our product scores consist of a combination of the following 3 components:
Popularity
Top10.com measures user engagement based on the number of clicks each listed brand received in the past 7 days. The number of clicks to each brand will be measured against other brands listed in the same query. Therefore, the higher the share of clicks a brand receives in any specific query, the higher the Click Trend Score. Top10.com accepts advertising compensation from companies, which impacts their (and/or their products’) position, and in some cases, may also affect their Click Trend Score.
Brand Reputation
Semrush is a trusted and comprehensive tool that offers insights about online visibility and performance. The Top10.com Total Score will consist of the brand's reputation from Semrush. The brand reputation is based on Semrush's analysis of clickstream data, which includes user behavior, search patterns, and engagement, to accurately measure each brand's prominence, credibility, and trustworthiness. If a brand does not have a Semrush score, the Top10.com Total Score will be based solely on the Click Trend Score and Products & Features Score (read below).
Features & Benefits
Top10’s editorial team researches and reviews products based on factors such as: range of products and services offered, ease-of-use, online accessibility, customer service, special awards, and more. Each brand is then given a score based on the offerings in each parameter. This score may be assigned by our editorial team or by AI-powered tools. Any score assigned by our AI tools is reviewed for accuracy by our editorial team. The specific parameters which we use to evaluate the score of each product can be found on its review page.
