An increasingly vital factor in optimization is the speed of the website. Decreasing the load time of a page makes impatient people very happy, especially when they are using a mobile device. Google has created Core Web Vitals as measurements for response times and speed of your website.
Core Web Vitals measures three aspects of Page Speed:
- Largest Contentful Paint: Measures the time it takes for the largest image or text block to load on the page. The target is under 2.5 seconds.
- First Input Delay: Measures how quickly people can interact with your page. The target delay is under 100 milliseconds.
- Cumulative Layout Shift: Measures how much the layout of the page changes as elements load. Typically, ads are the culprit here, as they cause content to move.
These measurements are used by Google and other search engines to measure the user experience and responsiveness on a page. Having poor scores in these categories does not mean that rankings will suffer. These elements are only a small part of the overall ranking algorithm.
