CWV stands for Core Web Vitals. It is a collection of specific measurements that Google uses to assess a website's user experience based on three key aspects: loading, interactivity, and visual stability. These measurements play an important role in a website's ranking in Google's search results, as they focus on how users experience the performance of a page.
What are the three main measurements in CWV?
- LCP (Largest Contentful Paint): Measures how long it takes for the largest visible element (such as an image or a block of text) to load. Google recommends an LCP of under 2.5 seconds for a good user experience.
- FID (First Input Delay): Measures how quickly the page responds to the first user interaction, such as a click or keyboard input. To ensure a good experience, FID should be under 100 milliseconds.
- CLS (Cumulative Layout Shift): Measures how stable the layout is while the page loads. If elements on the page move unexpectedly, it can create a bad experience. A good CLS score is under 0.1.
Why is CWV important?
CWV is important because Google uses these measurements to evaluate and rank websites based on how user-friendly they are. A good CWV score can improve your page's ranking in the search results, while a poor score can hurt it. Additionally, a fast and stable page is crucial for maintaining users' attention and reducing bounce rate.
Benefits of optimizing CWV:
- Improved user experience: A page that loads quickly and is easy to interact with keeps users engaged longer.
- Better SEO ranking: Google rewards pages with good CWV scores by giving them better positions in search results.
- Higher conversions: A faster and more stable page can lead to more sales, sign-ups or interactions, as users are not frustrated by slow or unstable pages.
To improve your CWV score, you can optimize images and scripts, ensure fast server response, and improve the layout's stability during loading. CWV is therefore an important part of any modern SEO strategy.
