6.SEO & Interaction Indicators

In today’s SEO environment, Google pays more and more attention to user interaction indicators, such as page dwell time, interactive performance, etc. This chapter will delve into how to optimize web page speed and user interaction experience to improve SEO effects and user satisfaction.

1. Google’s New Age SEO Metrics

With the development of Internet technology, Google constantly updates its search algorithm to provide a better user experience. In recent years, Google has introduced a series of new SEO indicators that focus more on user experience and web page performance.

Okay, here’s the updated Chinese description of core web metrics and their importance:

1.1 The Importance of Core Web Vitals

Core Web Vitals is measure page health and performance, and continue to play a small role in Google's search ranking algorithmsmesure。

These metrics are designed to measure several key aspects of user experience: loading speed, interactivity, and visual stability.

* Largest Contentful Paint (LCP)： This metric measures the time it takes for the largest content element visible in the viewport (for example, an image or a large piece of text) to complete rendering。 A good LCP score is 2.5 seconds or less.

* Interaction to Next Paint (INP): This metric has replaced First Input Delay (FID) in March 2024. INP measures how quickly a page responds to user interaction. It looks at the latency of all interactions that occur during the life cycle of a page visit. A good INP score is 200 milliseconds or less.

* Visual Stability (CLS, Cumulative Layout Shift): This metric quantifies the unexpected layout shift of visible content during page load. A good CLS score is 0.1 or less.

There is no need to force optimization. Such technical indicators only play a small role in rankings and mainly ensure a good user experience.

1.2 The rise of user interaction indicators

In addition to Core Web Vitals, Google is increasingly paying attention to other user interaction metrics:

* Length of time on page: The longer the user stays on the page, usually means the higher the quality of the content.

* Bounce rate: Measures the rate of users leaving the site immediately after visiting a page. A low bounce rate usually indicates highly relevant content.

* Page depth: The number of pages a user views in a session. High page depth indicates that users are interested in the content of the website.

* User engagement: Including user interaction behaviors such as comments, sharing, and subscriptions. High engagement indicates that the content is valuable to users.

These indicators jointly reflect user satisfaction with the website, so they should be given sufficient attention in SEO strategies.

2. Optimize loading performance (LCP)

LCP is one of the key indicators in Core Web Vitals, which directly affects the user’s perception of page loading speed.

2.1 Identify and optimize LCP elements

The LCP element is usually the largest visible element on the page and may be:

* Images: Use appropriate image formats (such as WebP) and sizes to achieve lazy loading.

* Video: Use video thumbnails as placeholders and only load the full video on user interaction.

* Large DOM elements: Optimize DOM structure and reduce unnecessary nesting.

Optimization strategy:

* For pictures, you can use the <picture> element to provide multiple formats and sizes.

* Use CDN to speed up resource loading.
