Embodiments herein include receiving, by a server, a request including a hyperlink directed to a source content. The server may determine whether a database associated with the server comprises the hyperlink. The database stores information of multiple entities each corresponding to one or more hyperlinks. In response to a determination that the database includes the hyperlink, the server may identify an entity corresponding to the hyperlink and provide information of the entity to the computing device. In some embodiments, in response to a determination that the database does not include the hyperlink, the server may identify related web content and return results to user. ## Claims ### Claim 1 A method, comprising: receiving, by a server, a request from a computing device, wherein the request comprises a link directed to a source webpage, and wherein the source webpage includes a subject of interest within content of the source webpage, and further wherein the request is for at least one piece of information (a) related to the subject of interest and (b) from at least one webpage (i) different from the source webpage and (ii) other than a version copy of the source webpage;
