Booster Sweeper helps you to optimize the Website speed further over the common caching and code minification plugins. Booster Sweeper allows you to dequeue assets, i.e. unload the unused CSS or JavaScript files. These are the files that aren’t necessary for certain page.
You see, with the most of the WordPress plugins or even themes, most of the assets are loaded over the whole site, while usually you do not need those resources for certain pages. By unloading those files that aren’t necessary you are reducing the overall size of the page and at the same time decreasing the number of http requests. This results in a better performance for the pages and, even if other things are configured well, in a better SEO score for your site.
The most obvious using scenario would be when…
