The invention discloses a method and an apparatus for analyzing the compatibility of a website under screen resolutions. The method comprises the steps of obtaining a target access log in a target time period, wherein the target access log is a log generated according to access information of a target website; extracting target access information from the target access log according to a preset condition, wherein the target access information comprises access information of accessing the target website by a plurality of terminal devices with different resolutions; performing statistics on a target proportion according to the target access information, wherein the target proportion is a proportion of separate access of the terminal devices with different resolutions to the target website in access of the terminal devices to the target website; and comparing the target proportion with a preset proportion, and analyzing the compatibility of the target website under the screen resolutions. Through the method and the apparatus, the problem of relatively low analysis efficiency caused by manual analysis of the compatibility of the website under different resolutions in related technologies is solved.
