页面信息
标题:
GitHub · Build and ship software on a single, collaborative platform · GitHub
长度: 77 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:
GitHub is where people build software. More than 150 million people use GitHub to discover, fork, and contribute to over 420 million projects.
长度: 142 字符; 最佳长度: 50 ~ 160 字符
Meta 关键词:
长度: 0 字符; 最佳长度: 10 ~ 255 字符
The length of your meta keywords seems to be outside the recommended range. Ideally, a meta keywords should be between 10 and 255 characters, including spaces.
Meta keywords are a specific type of meta tag that appear in the HTML code of a web page. They provide information to search engines about the topic of the page. Meta keywords were once used to help rank web pages in search engine results. However, due to the abuse by webmasters and marketers, Google claims to have stopped using them more than a decade ago. Despite this, there are still reasons to consider using meta keywords:
- Uncertain Impact on Google's Algorithm: While Google devalued meta keywords, it is uncertain if they were entirely removed from its ranking algorithm. Google keeps its ranking algorithms top secret to deter people from gaming the system.
- Other Search Engines and CMS: Other search engines like Yandex, Baidu, and Naver may still use meta keywords. Additionally, some internal CMS search systems, such as SOLR and Algolia, also utilize the meta keywords tag.
Best practices for Meta Keywords
- Relevance is Key: It is crucial to choose keywords that accurately reflect the content of your page.
- Keep it Limited: It is generally recommended not to exceed more than 10 meta keywords for a single page. Also, the content length should not exceed 255 characters (including spaces).
- Consider Long-Tail Keywords: Long-tail keywords are more specific and longer phrases that target a niche audience. These keywords can be highly effective in driving targeted traffic to your website.
Remember, meta keywords are just one aspect of search engine optimization (SEO), and search engines now place less emphasis on them compared to other factors. However, by following these best practices, you can still optimize your meta keywords effectively and improve the visibility of your web pages.
