We increasingly rely on third-party scripts to deliver site features – analytics, adverts, multi-variant testing, comments, recommendations, retargeting, social sharing etc.
Despite this explosion in third-party components there is little information on how they interact with our sites and what their impact on performance is.
In this session we’ll share the insights we have gained from analysing the impact of 3rd party scripts on the performance of sites we monitor. We’ll look at which third-parties are the most popular, how they interact with our pages and are they fast, slow, or inconsistent?
Attendees will come away with a better understanding of third-party performance and pointers on how to make informed decisions when choosing their third-parties.
