Abstract: Embodiments include computer implemented methods for generating a real-time personalized graduated evaluation metric associated with listings being displayed in a web browser. A user account can be authenticated by sending a set of login credentials to an authentication server and receiving an authentication token including user information. Web-based content can be displayed in the web browser application to determine that the web-based content corresponds to a listing page. A purchase metric can be generated for the listing based on a first set of listing data, a second set of listing data obtained using the first set of listing data, and the user information. A graduated evaluation metric can be selected based on the purchase metric satisfying a threshold associated with a first graduated evaluation metric and causing a web browser application to display a popup window containing a graduated visual indicia corresponding to the graduated evaluation metric.
