Certain aspects of the present disclosure provide techniques for facilitating text inputs with long-tail keywords from a user in a social question and answer (Q&A) application. One example method generally includes receiving, at a server, a text input from the user at a client computer, and applying, a predictive model to the text input. The method further includes determining based on the predictive model, an increase in user traffic that is predicted to be generated from the text input and determining, a user interface (UI) to be generated for display to the user for subsequent interaction based on the increase in user traffic. The method further includes sending the UI to the client computer and receiving a subsequent text input from the client computer.
