页面信息

标题:
TLS/SSL Certificate Authority | Leader in Digital Trust | DigiCert
长度: 66 字符; 最佳长度: 10 ~ 60 字符

HTML 标题标签是页面 SEO 最重要的元素之一,出现在搜索结果、浏览器选项卡和书签中。

您的标题标签似乎不符合理想长度。

Google 的搜索结果会截断超过 60 个字符的标题;Bing 的搜索结果会截断超过 70 个字符的标题。

以下是元标题的最佳做法:

  • 标题长度保持在 10-60 个字符之间。
  • 使关键字/关键短语显而易见
  • 融入相关的有力词语
  • 清晰简洁
Meta 描述信息:
DigiCert is the leading TLS/SSL Certificate Authority specializing in digital trust solutions through DigiCert ONE, the first platform built for mastering PKI, IoT, DNS, Document, and software trust.
长度: 199 字符; 最佳长度: 50 ~ 160 字符

The length of your meta description seems to be outside the recommended range. Ideally, a META DESCRIPTION should be between 50 and 160 characters, including spaces.

A meta description tag serves as a concise and informative summary of a web page's content, aiming to engage and inform users about the page's topic.

Google relies on the actual content of the page to generate a snippet for search results, but it may also utilize the meta description for a more descriptive representation of the page.

Meta descriptions act as a compelling pitch to persuade users that the page aligns with their search intent. While there's no strict character limit, Google truncates the snippet in search results as necessary to fit the device's width.

Best practices for Meta Descriptions

  • Length: Maintain a description length of 50-160 characters to ensure optimal visibility in search results.
  • Uniqueness: Craft unique descriptions for each page on your website to differentiate their purposes and content.
  • Accuracy: Create descriptions that precisely depict the specific content and purpose of the page.
  • Keywords: Ensure that each web page has a unique meta description containing important keywords relevant to the page's content.
