Site speed
The speed of your site is a critical factor in the popularity and convenience of the site. Search engines give this parameter a very close attention.
["The popular Twitter Bootstrap framework is available in 2 compressed and regular versions. The difference in size between these two versions is 70%."]
You should comply with the following rules regarding site speed.
- The webpage loading speed should be less than 0.2 seconds.
- Gzip compression should work for all text pages. That is, pages which have mime type = text / *. This is a page, CSS and javascript files. This can be done either using the settings of your web server or CMS. We recommend using nginx to compress files.
- Connecting Javascript files should be at the bottom of the page.
- The size of the Html page should not exceed 120 kb.
- The page should have a minified JS and CSS code. Minification means a particular process that removes all spaces, line breaks and extra characters from your CSS and js files. Perhaps your CMS supports such compression or allows you to install a separate module. You can do this with the help of the following programs https://github.com/cssnano/cssnano and https://github.com/mishoo/UglifyJS2 or by using this site; http://refresh-sf.com/
According to statistics from Google; if the speed of page generation falls from 0.3 to 0.5 seconds, then the number of search requests falls by a third.
