Introduction
Third-party scripts can cause negative load-time effects. Why is this an issue? Well, in Google’s view, a poorly-optimized page should not rank highly. Instead, search results should favor pages with fundamental design strengths — including JavaScript minification, rapid execution time, and render-friendly scripting.
In reflection of this belief, Google has planned the gradual release of a major update to its search algorithm that is scheduled for June through August of 2021. This update will increase the importance of a page’s loading speed as a contributing factor to a web page’s overall ranking on Google’s search results page. As a result, how third-party scripts impact page load times is becoming more important than ever.
