Today when i opened my account i got this message: - Minimize the size of JavaScript resources on your sites We have analyzed some of the pages on your sites that serve the most ads, and have detected Page Speed problems that create a highly negative user experience for some users. Frequently viewed pages on your sites are referencing unnecessarily large JavaScript files that would benefit from comment stripping and whitespace removal. This is called minification What is meaning of this, and is there any risk with my account due to this?
you got this message in your Adsense account or in your Webmaster Tools? it means the javascript in your pages is too slow and fat.
