The humble <img> element has gained some superpowers over the years. Given how central it is to image optimization on the web, let’s catch up on what it can do and how it can help improve user experience and the Core Web Vitals.
Third-party scripts, or "tags" can be a source of performance problems on your site, and therefore a target for optimization. However, before you start optimizing the tags you have added, make sure that you are not optimizing tags you don't even need. This article shows you how to assess requests for new tags, and manage and review existing ones.
This process starts with an awareness that we are not an emotion, we are having an emotion. The emotion is a transitory state of mind and body, not an identity. It can feel stilted and silly to say "I'm having the experience of anger" rather than "I'm angry!" But we're well-served by heightening our awareness of the distinction between the two. Perhaps "I'm feeling angry" is a reasonable compromise.
Saying that someone else "makes us feel" an emotion suggests that they are responsible for our emotional state, and that's highly problematic.
Having established some distance between our sense of self and our subjective emotional experience, we can then assess the steps through which we have contributed to our own response.
It might seem that such selectors would be a speed problem. However, the selector matching performance is fast. The CSS declarations are so friendly to compression algorithms that the effort required to optimise a CSS selector is usually better spent working on other parts of your application with a greater return on investment.
The other half of this statement is in the ever growing Google of it all. This update is dipping a toe into creating other measurable User Satisfaction/UX metrics. So you should be thinking-- what annoys me about websites? How would I measure that? And is my own website up to the task?
the reason we’ve been so dependent on lab data for so long is because RUM data is noisy. The steps CrUX takes to reduce this does help to give a more stable view, but at the cost of it making it difficult to see recent changes.
Don’t use runtime CSS-in-JS if you care about the load performance of your site. Simply less JS = Faster Site. There isn’t much we can do about it. But if you want to see some numbers, continue reading.
Optimizing websites for a quality user experience is key to the long-term success of any site on the web and Core Web Vitals is an initiative Google has provided as a unified guidance for quality signals that are essential to delivering a great user experience on the web. Addy Osmani and Kristofer Baxter, from Google, join us to talk more about Core Web Vitals.
The first step in improving speed is establishing who is responsible for the effort. Other than responsibility, it’s invaluable to gather a diverse group who can contribute unique ideas to the brainstorming and evaluation session (more on that below). By including people from different business areas, you’ll allow knowledge to spread throughout the organisation more freely too.
