The idea behind this feature is simple, provide editors with the flexibility to change robots.txt files on the go.
The Robots.txt page (backed by SBRobotsTxt PageType) should be created by the editor for the site under Start Page.
The physical rebots.txt file content (if any) will be replaced with the CMS robobts.txt page content. The fallback behaviour of the /robots.txt URL is the content of the physical rebots.txt file (if any) otherwise the default 404 error page will be shown.
IMPORTANT:
-
If there is a physical robot.txt exists in the site root, always purge the CDN cache after the deployment or site restart. Deleting the physical robots.txt file from the site root is recommended to ensure editable robot.txt content loads without a problem.
-
If you are using IIS URL Rewrite rules to add a trailing slash at the end of the URL, add the following in the rule to ignore the robots.txt route
<add input="{URL}" pattern="\robots.txt" negate="true" />
There are some helper methods in the package to get external URLs of the page. The developer can use these methods for their implementations
usage
var urlHelper = ServiceLocator.Current.GetInstance<SeoBoost.Business.Url.IUrlService>();
There are three methods available to get external URL for the content
string GetExternalUrl(ContentReference contentReference);
string GetExternalFriendlyUrl(ContentReference contentReference, string culture);
string GetExternalFriendlyUrl(ContentReference contentReference);
