Poor performance of third-party services can have other business impacts even if your website does not use advertising.
Each stage has its unique challenges and potential pitfalls, as other casestudies show. It also opens up the possibility for more effective use of caching strategies, potentially enhancing load times further. This caching mechanism also improves the website’s resilience to distributed denial-of-service (DDoS) attacks.
Casestudies abound. Review OWASP’s recommendations and bestpractices with your developers. Use a static analysis tool or a vulnerability scanner (available from all major vendors such as Qualys , Veracode , or Micro Focus ) to assess how well you are complying with security bestpractices.
Recently Grigorik has been championing this approach and the Google Pagespeed Insight rules have been updated to reflect this bestpractice with recommendations on how to reduce the size of "above the fold" content. All CMS's should be offering this level of image manipulation and caching. Source: SpeedCurve.
In case you have any doubts, countless casestudies have proven a consistent and demonstrable correlation between page speed and business and user engagement metrics like conversions, bounce rate, and search rank. This is often referred to as a cold cache. Yet 16 out of 20 sites did not have bfcache restoration enabled.
According to Google, the bestpractice for a website’s speed is to keep it under 3 seconds load time. As we can see from the graph below, this bestpractice is far from being met for sites based in the United States. Fonts are render-blocking as we discussed in our casestudy on web font performance.

You need a business stakeholder buy-in, and to get it, you need to establish a casestudy on how speed benefits metrics and Key Performance Indicators ( KPIs ) they care about. Study common complaints coming into customer service and see how improving performance can help relieve some of these common problems. How to get there?
