In the page-level view, each URL retains its own record; in the domain-level view, multiple URLs are grouped together. Grouping requires a rule: it can use the full hostname or combine subdomains under a registered domain. The original URL should remain available. ## Why it matters for marketing The domain-level view helps identify recurring publications, while the page-level view makes it possible to find the article containing specific information. If the team receives only the aggregated total, it may look for corrections in the wrong place. It also needs to know whether the total represents citations, distinct URLs, or responses containing that domain: these measure different things. ## Practical example Suppose a response about travel cites two guides from a portal and a page on its reviews subdomain. The analyst finds three URLs but groups them under one registered domain and counts the domain once in that response. After identifying an outdated baggage policy, the analyst opens the corresponding URL to guide the revision of that specific guide. ## How to apply or verify Record the URL received, hostname, grouping key, response, and date. Document how subdomains, parameters, redirects, and duplicates are handled. To identify the registered domain, use a library with an up-to-date public suffix list, rather than simply taking the last two parts of the address. Check shared-hosting cases and preserve the path from the aggregated total to the individual records. ## Important distinctions A domain is not equivalent to an organization or brand ownership: a company may maintain several domains, and hosting services may host different parties. Grouping addresses is an analytical decision, not proof of editorial control.
