Implementations an optimizing a browser rendering process that identifies content neutral web pages and renders such web pages without scripting. An example method includes generating a first rendering result of a web page with scripting turned on and generating a second rendering result of the web page with scripting turned off. The method also includes comparing the first rendering result with the second rendering result to determine whether the web page is content neutral and storing a URL for the web page in a list of content neutral URLs when the web page is content neutral. The method can further include receiving a request to render a web page identified by a URL, prior to rendering, determining that the URL is a content neutral URL, and rendering the web page with scripting turned off responsive to determining that the URL is a content neutral URL.
