Abstract: Methods, systems, and apparatus for increasing comment visibility are described. In one aspect, a method includes receiving a comment request for a comment to be included in a comments field of a content page, determining that the comment will be hidden from users when online content is presented to the users based on a number of other comments presented in the comments field exceeding a threshold number, and modifying a position of the comment in relation to positions of the other comments presented in the comments field to increase visibility of the comment to the users, including modifying the position of the comment from a first position that is hidden from the users to a second position that is visible to the users.

Abstract: Methods, systems, and apparatus for generating and providing display error indications. In one aspect, a method includes accessing data defining display areas and, for each display area: respective display area borders that are different from display area borders of other display areas; and display data for each of a plurality of objects that are rendered in the display area, the display data defining, for each object: a display position of the object; display dimensions of the object; and content data defining content of the object; wherein each object in each display area corresponds to a respective object in each other display area; receiving user input specifying a change in the display data of a first object in a first display area and, in response, determining whether the change causes a display error; and for each display area for which the change causes a display error, generating an error indication.
