Over time, create redirects from one page or URL to another. ## When to Use the Alias, Mapping Rule, Static Mapping, and URL Redirect Features **Redirecting host-only URLs** Always click App Launcher ![App Launcher](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-cc-b2c_merchandiser_administrator-264-0-0-production-enus/ea76f372-6cfa-42a6-8e7c-05c6df7abed8/cc/b2c_merchandiser_administrator/images/appLauncher.png), and then go to **Merchant Tools** | **Site** | **SEO & Discoverability** | **Aliases.** Hostname aliases generate 301 redirects for host-only URLs.

For example, if you change the name of a category. This is the only feature that can be used to redirect B2C Commerce URLs. See [Creating a Redirect from a B2C Commerce URL](https://help.salesforce.com/s/articleView?id=cc.b2c_creating_a_redirect_from_a_digital_url.htm&release=264.0.0&type=5 "The URL redirects feature redirects obsolete or unavailable B2C Commerce pages to currently available pages, or to a specific URL outside B2C Commerce. You can also schedule when a redirect becomes active and when it expires."). For more information about how this feature works, see [URL Redirect Processing and Examples](https://help.salesforce.com/s/articleView?id=cc.b2c_url_redirect_processing_and_examples.htm&release=264.0.0&type=5 "Use the URL Redirect module to create redirects from existing B2C Commerce URLs to new B2C Commerce URLs."). **Redirecting legacy Platform URLs** If the redirect is from a legacy platform different than B2C Commerce, mapping depends on the type of redirect URL. - A content page or unique or unusual - in this case you want to click App Launcher ![App Launcher](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-cc-b2c_merchandiser_administrator-264-0-0-production-enus/ea76f372-6cfa-42a6-8e7c-05c6df7abed8/cc/b2c_merchandiser_administrator/images/appLauncher.png), and then select **Merchant Tools** | **Site** | **SEO & Discoverability** | **Static Mappings.**, which is used for specific pages, whether they are landing pages or searches that don't conform to a general pattern. See [Static Mappings.](https://help.salesforce.com/s/articleView?id=cc.b2c_static_mappings.htm&release=264.0.0&type=5 "Create static mappings from existing legacy URLs to new URLs in B2C Commerce. The URLs can be either dynamic pipeline calls or static resources, however, make sure that source URLs are unknown to the system. Replicate static mappings from Staging to Production instances. The file size of the configuration in Business Manager is limited to 2 MB. If you exceed the limit, use the site import and export functionality to update the static mappings.") - A product or category page or conforms to a pattern - in this case you want to click App Launcher ![App Launcher](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-cc-b2c_merchandiser_administrator-264-0-0-production-enus/ea76f372-6cfa-42a6-8e7c-05c6df7abed8/cc/b2c_merchandiser_administrator/images/appLauncher.png), and then select **Merchant Tools** | **Site** | **SEO & Discoverability** | **Dynamic Mappings.** - mapping rules identify the pattern of an incoming URL and map it to a pattern for a B2C Commerce URL. Creating a few mapping rules can let you manage many URLs from a legacy site efficiently. Mappings can be maintained in B2C Commerce for as long as you wish. We don't recommend removing them, because it isn't possible to predict when other site owners or search engines update their links, and removing the mappings prematurely causes you to lose traffic. See [Dynamic Mapping](https://help.salesforce.com/s/articleView?id=cc.b2c_dynamic_mappings.htm&release=264.0.0&type=5 "Configure dynamic mapping rules that use a pattern to identify a URL from your legacy site and automatically redirect it to a B2C Commerce URL. It isn't possible to use mapping rules to redirect an existing or obsolete B2C Commerce URL to a different B2C Commerce URL, nor is it possible to create redirects for static resources like images."). ## Legacy Platform URL Redirects and Site Rankings Most merchants migrate from an existing site to B2C Commerce. Usually, the existing site has built up search rankings and links on other sites to their site that drive traffic to the merchant. Use B2C Commerce to create mappings between old links and new pages so that you don't lose traffic from other sites and search engines. If you don't create these mappings, the old links don't work, and your SEO rankings can be severely impacted. To create redirects for these links, we have three features: B2C Commerce hostname aliases, B2C Commerce Site URL-Mapping Rules, and Site URL Static Mapping. See [Configuring 301 Redirects for Legacy URLs](https://help.salesforce.com/s/articleView?id=cc.b2c_configuring_301_http_redirects_for_legacy_urls.htm&release=264.0.0&type=5 "301 Redirects are used for permanent URL redirection, sending users to a different URL than the one they originally typed into their browser or selected from search engine results. The 301 redirect is considered a best practice for upgrading users from HTTP to HTTPS."). Links that become obsolete because you change a category name on B2C Commerce also need permanent redirects so as not to lose customers who have bookmarked products and to retain your rankings. To create redirects for these links, use the URL redirect feature. B2C Commerce reserves `sitemap*xml` as a redirect keyword for XML sitemaps used by search engines to crawl the site. This string can't be used when creating redirects using any of the B2C Commerce URL redirect features. However, if you are redirecting a legacy sitemap page that showed an overview of your old site, you can set up a redirect using the string `sitemap` or `SiteMap`. See [Sitemap Overview](https://help.salesforce.com/s/articleView?id=cc.b2c_sitemap_overview.htm&release=264.0.0&type=5 "Sitemaps are XML files that provide search engines, such as Google and Yahoo with information about a website so crawler can index it more efficiently. Sitemaps contain a list of all the URLs available for indexing and can provide the search engine with additional information, such as when a page was last updated, frequency of updates, and the relevance of a page. Search engines use this information to construct links to your site and control the ranking of links within its search results."). ## Error Pages If a user mistypes a URL or attempts to reach a page that no longer exists, they see a 404 page. You can create custom 404 pages that let them enter the site successfully. See [Creating 404 Error Pages with Alternate Paths](https://help.salesforce.com/s/articleView?id=cc.b2c_creating_404_error_pages_with_alternate_paths.htm&release=264.0.0&type=5 "Create error pages that let a customer get to the home page of your site, even if they experience a 404 error because they’re linking to an expired page or have a broken URL.").
