The same content may be accessed through a web site, page break, case path, end slash, HTTP and HTTPS or multiple fields. If these URLs are accessible, external links, user behaviour and content understanding signals will be dispersed, and the answer system may also refer to versions that do not want to be displayed. Canonical is used to express the preferred norm URL, but it is a signal rather than a mandatory command and must be consistent with redirection, Setmap and internal links.
The Google Open Document views permanent reorientation and rel=canonical as a strong normative signal, while Sitimap is a weaker signal. The reference to Canonical can specify the page’s own normative address. More than one signal is more clear about what really should be a duplicate page; however, the pages in different languages should not be all Canonical to English pages, otherwise the other languages may not be eligible for independent indexing.
Starts with a list of sources that generate duplicate URLs and determines the standard version of each set of contents. The old path that can be phased out uses 301 jumps, the filtering or tracking parameter page that still needs to be visited adds to Canonical, Sitemap only lists the standard pages to the main page, and the links to the site only use the standard address. Templates should output absolute URLs and properly process protocols, domain names, language prefixes and path codes. Do not use robots.txt to prevent reptiles from reading Canonical, and do not allow JavaScript to modify the label after loading.
Checks for differences in content, link signals and re-direction if the page source code Canonical, HTTP jump, Sitimap address and internal link targets are not consistent with the " User Declaration Page" and "Google Select Pages". If the log captures the URL in large numbers, the template that generated these links should continue to be managed.
Common errors include Canonical pointing to 404 or re-direction pages, the simultaneous output of two Canonical pages from different templates, all pages pointing to the first page, the Chinese page pointing to the English page, and the Setmap listing of irregular URLs.
When you land on the ground, the words “repeated URL identification, regular address decision-making, multiple signal consistency, indexing results” should be included in the same release checklist, specifying who is responsible for the content, who is responsible for the technology and the date of the review. Any change must be accompanied by a check of the visible content of the page, HTML source code, structured data, internal links and site maps, so that the front desk is not updated and machine reading layers remain old values. GEO is not a one-time installation plugin and does not guarantee that any platform will be quoted; it is a set of content and technical works that continuously improve the accessibility, validation, attribution and citation of information.
