Render-blocking scripts refer to JavaScript or CSS files that prevent a web page from loading quickly. These scripts are called “render-blocking” because they block the rendering of the page until they are loaded, which can cause delays and negatively impact the user experience.
In SEO, render-blocking scripts can harm a website’s performance and ranking in search engine results. Google’s algorithms take page load speed into account when determining a site’s ranking, so a slow-loading page can negatively impact a website’s visibility and organic search traffic.
To improve the performance of a website and avoid the negative effects of render-blocking scripts, it’s important to optimize the scripts and reduce their impact on page load time. This can be done by minifying and combining scripts, using asynchronous loading, or moving the scripts to the bottom of the page.
By addressing render-blocking scripts and improving page load speed, businesses can improve their SEO and enhance the user experience of their website.
