This is a file that gives search engines information about the pages a company wants indexed or crawled. You can find this page by going to YOURDOMAIN/robots.txt. Most robots.txt files look like this
User-agent: * Disallow: /
Here’s mine for this site, it disallows some admin areas and includes a link to my sitemap.
User-agent: * Allow: /wp-admin/admin-ajax.php Disallow: /members-home/ Sitemap: https://therecipeforseosuccess.com/sitemap_index.xml
Note: You don’t need to have your sitemap in your robots.txt, it’s a nice to have.
