Whether you’re trying to get traffic to your website or looking to maximise conversions, your site optimisation is a key factor that can influence your marketing activity.

This course will start by exploring what defines website performance and the impact it has on your business. This is followed by an outline of the metrics that contribute to page load time. We'll explore how optimising a site has a dramatic effect on customer experience and the impact this has on the success of your product or service.

Our trainer will give you a demonstration of the free and paid-for performance tools that are available and how to use them effectively. We’ll also cover the difference between synthetic and real user data, when to use them and what reports and resources can be generated to review with your team.

You'll learn what a performance waterfall is and how to use it to obtain a detailed analysis of the page resources. This will allow you to easily locate blocks and bottlenecks in page load times and formulate an improvement plan quickly.

Our Web Performance: Fundamentals course is available at our training centre in The Shard, London. We also offer private training courses which are ideal if you have a whole team that requires training.
