What is a robots.txt file?
Before search engines crawl your website, they check the robots.txt file for instructions. Robots.txt is a very powerful file, so tread lightly when updating it. Double-check that you are indeed communicating your intended goals.
You can view your robots.txt file at www.mywebsite.com/robots.txt.
WordPress & Robots.txt
WordPress websites in development typically use the robots.txt file to block crawlers from indexing the website. The code looks like:
“User-agent:” followed by an asterisk addresses all crawlers. “Disallow:” followed by a forward slash instructs crawlers to not index any page on the website.
To update your robots.txt file, navigate to the Reading settings in your WordPress website. When you’re ready for search engines and people to visit your website, go to Settings > Reading in the left-hand menu, and uncheck the box for “Discourage search engines from indexing this site”.
Then, your robots.txt file will read:
Should I add my XML sitemap to the robots.txt file?
Rather than adding your XML sitemap to the robots.txt file, submit it directly to Google Search Console and Bing Webmaster Tools.

An easy way to update your robots.txt in WordPress is in the Yoast SEO plugin.

What are robots meta directives?
Robots meta directives provide firm, detailed instructions on how search engines should crawl and index an individual page’s content.
<meta name=“robots” content=“[parameters]”>
The most common content values are:
- Nofollow – Don’t follow the links in the page’s content.
- Follow – Follow the links in the page’s content.
- Noindex – Don’t index the page.
- Index – Index the page, please.
If you want to exclude a page from search engine results, but you want crawlers to follow the links on that page, use:
<meta name=“robots” content=“noindex,follow”>
