Ranking Methodology

To evaluate the performance of contractors, our methodology employs a systematic approach that considers various factors contributing to customer experience and satisfaction. We focused on assessing the accessory dweling unit builders in the Austin area. The methodology involves assigning weightings to specific categories based on their significance in determining customer service quality. Here’s the breakdown of the categories and their respective weightings:

• Average Customer Satisfaction (35%): This metric represents the average rating given by customers across the same review platforms as the Average Customer Satisfaction Score. A higher average rating indicates greater overall satisfaction with the service provided.
• Service Rating Score (25%): We analyze the ratio of high (4-5 stars) to low (1-2 stars) ratings for each business across multiple review platforms: Google, Houzz, and Yelp. A higher percentage of positive reviews contributes to a higher score, reflecting better customer satisfaction.
• Complaint Percentage (25%): We analyze the ratio of complaints to total reviews for each business. A lower complaints ratio indicates better service quality and results in a higher score.
• Business Hours and Availability (10%): The operating hours of each business are assessed to gauge accessibility. Companies with extended operating hours are awarded a higher score, as they offer greater convenience to customers.
• License Status (5%): We verify the licensing status of each contractor with their local licensing board to ensure legal compliance. Companies with valid licenses receive a higher score, reflecting professionalism and adherence to regulations.
• Total Score: We determined the overall rating for every contractor by calculating a weighted average, with the category weight determining the amount the subscore contributed to the total score 

Additional Note: Service Rating Score, Average Customer Satisfaction, and Complaint Percentage are calculated with a Bayesian estimate to account for if the contractor has a low number of total reviews. A Bayesian average is a statistical method used to calculate the average of a set of data points while taking into account prior information or beliefs about the distribution of the data. It combines the observed data with a prior distribution to generate a more accurate estimate of the true average.
