To know if the photos effectively attract potential buyers, you can look for signs of engagement and interest from viewers. You can also use metrics such as the number of views, inquiries, and showings the property receives and feedback from potential buyers and their agents. Additionally, you can compare your listing’s performance to similar properties in the area to see if your photos are helping your property stand out. Remember, the effectiveness of your photos will depend on various factors, including the property’s features, location, and price, as well as the quality and presentation of the images.
