A/B Testing, Ads and other 3rd Party Tags

On 7th March 2018 at The Financial Times as part of The butterfly effect and tech / A-B Testing, Ads and other 3rd Party Tags

Increasingly we rely on third-party scripts to deliver business-critical features of our sites – analytics, adverts, multi-variant testing, comments, recommendations, retargeting, social sharing etc.

These scripts often get added with the seemingly innocent “it’s just a snippet of JavaScript”, but they can have a dramatic impact on performance – from slowing the loading speed though to ‘janky’ interactions.

In this talk Andy will explore how some popular types of 3rd parties affect performance, strategies for managing them and examples from sites that have tamed them.

You’ll come away with a better understanding of third-party performance, and pointers on how to reduce their impact on your visitors’ experience.
