The report cites heavier pages, often weighed down by excessive scripts and tags, as one of the reasons for the slowdown. These problems can be mostly eliminated by using a solution like the Trusted Data Interchange (TDI), which permits rules-based script execution and helps to limit the scripts to only the most relevant and essential.
Radware also cited “Time to Interaction” (TTI) as relevant statistic to monitor when determining how to increase user engagement. Studies have shown that a one-second delay in page time can decrease user conversion by up to 7%. TDI can help here, too, as the system loads tags asynchronously and let users more quickly interact with website content instead of waiting for the page to complete loading.
