Recently one of our readers asked us for tips on how to optimize the robots.txt file to improve SEO. Robots.txt file tells search engines how to crawl your website which makes it an incredibly powerful SEO tool. In this article, we will show you how to create a perfect robots.txt file for SEO.
最近，我们的一位读者向我们询问了有关如何优化robots.txt文件以改善SEO的提示。 Robots.txt文件告诉搜索引擎如何抓取您的网站，这使其成为功能强大的SEO工具。 在本文中，我们将向您展示如何为SEO创建一个完美的robots.txt文件。
Robots.txt是网站所有者可以创建的文本文件，用于告诉搜索引擎机器人如何在其网站上抓取页面并将其编入索引。
It is typically stored in the root directory also known as the main folder of your website. The basic format for a robots.txt file looks like this:
它通常存储在根目录(也称为网站的主文件夹)中。 robots.txt文件的基本格式如下所示：
You can have multiple lines of instructions to allow or disallow specific URLs and add multiple sitemaps. If you do not disallow a URL, then search engine bots assume that they are allowed to crawl it.
您可以使用多行说明来允许或禁止使用特定的URL并添加多个站点地图。 如果您不禁止使用URL，则搜索引擎漫游器会假定它们被允许对其进行爬网。
Here is what a robots.txt example file can look like:
这是robots.txt示例文件的外观：
In the above robots.txt example, we have allowed search engines to crawl and index files in our WordPress uploads folder.
在上面的robots.txt示例中，我们允许搜索引擎对WordPress上载文件夹中的文件进行爬网和编制索引。
After that, we have disallowed search bots from crawling and indexing plugins and WordPress admin folders.
在那之后，我们禁止搜索bot搜寻和索引插件和WordPress admin文件夹。
Lastly, we have provided the URL of our XML sitemap.
最后，我们提供了XML网站地图的URL。
您是否需要WordPress网站的Robots.txt文件？ (Do You Need a Robots.txt File for Your WordPress Site?)
If you don’t have a robots.txt file, then search engines will still crawl and index your website. However, you will not be able to tell search engines which pages or folders they should not crawl.
如果您没有robots.txt文件，那么搜索引擎仍会抓取您的网站并为其编制索引。 但是，您将无法告诉搜索引擎它们不应该抓取哪些页面或文件夹。
This will not have much of an impact when you’re first starting a blog and do not have a lot of content.
当您第一次创建博客且内容不多时，这不会产生太大影响。
However as your website grows and you have a lot of content, then you would likely want to have better control over how your website is crawled and indexed.
但是，随着网站的发展和内容的丰富，您可能希望更好地控制网站的爬网和索引方式。
Here is why.
这就是为什么。
Search bots have a crawl quota for each website.
搜索机器人对每个网站都有一个抓取配额。
This means that they crawl a certain number of pages during a crawl session. If they don’t finish crawling all pages on your site, then they will come back and resume crawl in the next session.
这意味着他们在爬网会话期间对一定数量的页面进行爬网。 如果他们还没有完成对您网站上所有页面的爬网，那么他们将返回并在下一个会话中继续爬网。
This can slow down your website indexing rate.
这可能会降低您的网站索引率。
You can fix this by disallowing search bots from attempting to crawl unnecessary pages like your WordPress admin pages, plugin files, and themes folder.
您可以通过禁止搜索漫游器尝试爬网不必要的页面(如WordPress管理页面，插件文件和主题文件夹)来解决此问题。
By disallowing unnecessary pages, you save your crawl quota. This helps search engines crawl even more pages on your site and index them as quickly as possible.
通过禁止不必要的页面，可以保存爬网配额。 这有助于搜索引擎在您的网站上抓取更多页面并将它们编入索引。
Another good reason to use robots.txt file is when you want to stop search engines from indexing a post or page on your website.
使用robots.txt文件的另一个很好的理由是，当您要停止搜索引擎将网站上的帖子或页面编入索引时 。
It is not the safest way to hide content from the general public, but it will help you prevent them from appearing in search results.
这不是向公众隐藏内容的最安全方法，但是它将帮助您防止内容出现在搜索结果中。

By adding sitemaps to robots.txt file, you make it easy for Google bots to find all the pages on your site.

最后的想法 (Final Thoughts)
The goal of optimizing your robots.txt file is to prevent search engines from crawling pages that are not publicly available. For example, pages in your wp-plugins folder or pages in your WordPress admin folder.
优化robots.txt文件的目的是防止搜索引擎抓取不公开的页面。 例如，wp-plugins文件夹中的页面或WordPress admin文件夹中的页面。
A common myth among SEO experts is that blocking WordPress category, tags, and archive pages will improve crawl rate and result in faster indexing and higher rankings.
SEO专家之间的一个普遍神话是，阻止WordPress类别，标签和存档页面将提高爬网率，并导致更快的索引编制和更高的排名。
This is not true. It’s also against Google’s webmaster guidelines.
