As the popularity of your website increases, there is no doubt that the number of active visitors will grow to the same extent. You are probably going to ask yourself how to deal with this and where is the problem in it. Well, if you are thinking about a huge number of visitors and a possibly higher advertising revenue you can’t see a single downside, but here’s the trick:  your website (if not optimized) won’t be able to be as responsive as before.

One way to optimize your website is using a script that combines and compresses CSS and JavaScript files. Eliminating render blocking is just part of the whole procedure. Most modern websites use JavaScript to add extra functionality to it such as animations and dynamic actions. They also use CSS files to streamline the visual style on all pages of the site. In both cases, it is recommended to keep this information in separate files instead of entering the entire code into a HTML file. That’s all render blocking is about.

Follow the impact your website has upon users

Once you start optimizing your website you should start tracking the results you are obtaining. For instance, check your Page Speed before and after you made some changes. The user experience should be as pleasurable and clean as possible and that is the one thing you’ll want to obtain for your website. Also, make sure you follow up if there are any side effects of lining up your code after you’ve eliminated render blocking JavaScript and CSS. If everything works fine, you have nothing to worry about. If there are problems with the way your website works, check the changes twice or think about a clean start.
