Improve your crawling
Use these techniques to help Google discover the right pages on your site:

• Submit a sitemap.
• Submit crawl requests for individual pages
• Use a simple, human-readable, and logical URL paths for your pages and provide clear and direct internal links within the site.
• If you use URL parameters on your site for navigation, for instance if you indicate the user’s country in a global shopping site, use the URL parameters tool to tell Google about important parameters.
• Use robots.txt wisely: Use robots.txt to indicate to Google which pages you’d prefer Google to know about or crawl first, in order to protect your server load, not as a method to block material from appearing in the Google index.
• Use hreflang to point to alternate language pages.
• Clearly identify your canonical page and alternate pages.
• View your crawl and index coverage using the Index Coverage Report

Improve your indexing
There are many techniques to improve Google’s ability to understand the content of your page:

• Prevent Google from crawling or finding pages that you want to hide using noindex. Do not “noindex” a page that is blocked by robots.txt; if you do so, the noindex won’t be seen and the page might still be indexed.
• Use structured data.
• Follow the Google Webmaster Guidelines.

• Read our SEO guide for more tips.

  
  Improving your serving

• If your results are aimed at users in specific locations or languages, you can tell Google your preferences.

• Be sure that your page loads fast and is mobile-friendly.
• Follow the Webmaster Guidelines to avoid common pitfalls and improve your site’s ranking.
• Consider implementing Search result features for your site, such as recipe cards or article cards.
• Implement AMP for faster loading pages on mobile devices. Some AMP pages are also eligible for additional search features, such as the top stories carousel.

• Google’s algorithm is constantly being improved; rather than trying to guess the algorithm and design your page for that, work on creating good, fresh content that users want, and following our guidelines.

  要点

• 设置好 HTML 中的 Title、URL、Keywords、Description

• 页面中的内容是否可以正常显示。如果内容是动态生成的，那么整个系统对于搜索引擎的体验将会特别。尽管 Google 可以动态的渲染页面，但是仍然会有一些影响。
• 页面的内容是否以推荐的 HTML 标签写的。如只有一个 H1 用于作内容的标题，多个 H1 标签可能会造成和 Title 不一致，导致显示在搜索引擎上的结果有误。
• 页面中的内链是否分配得合理。页面中是不是会有指向重要页面的链接，如首页。或者每个分类的详情页都会有链接，并链接到列表页。这样一来，列表页的排名就会比较高。
• 判断页面中的外链是否需要 nofollow 标签。
• 如果有独立的移动站点，要检测一下，是不是需要 rel=“canonical” 来表明他们的关系。
• 是否需要采用 rel=“next” 和 rel=“preve” 来指明页面间的关系，以让第一页拥有较高的排名。同时还能为浏览器开启 Prefetch 功能。
• 等等
