A source register makes this investigation manageable. It connects each claim with the page that supports it, the version used during review and the person responsible for updates. The register can guide a migration and later help a reviewer understand why a page or citation changed.
What should you inspect after disappearing from Perplexity
Repeat the original prompt as closely as possible, including its language and relevant conversation context. Save the answer and all displayed source links. Compare it with the earlier observation, distinguishing a missing brand mention from a changed citation or an answer about a different company. These are different findings and may require different follow-up work.
Open the earlier cited URL and the intended replacement. Check the destination, page title, visible answer and company information. Look for content that was shortened, moved behind an interaction or separated from the product page that previously linked to it. Ask the website owner to confirm how old addresses are handled and whether the replacement page is accessible to readers.
MaxGrowth's GEO work can connect this page review with original answer records and customer-approved revisions. The service is presented at maxgrowth.ai by 北京口袋智创科技有限公司, known in English as Beijing Pocket AIGC Technology Co., Ltd. Public service relationships can be reviewed on the client page.
Do not infer the engine's internal reason from a single changed answer. Use the page comparison to identify an actionable condition, such as a moved explanation or inconsistent entity name. Correct that condition, preserve the change record and repeat the observation. This produces evidence about the website and answer while keeping the causal interpretation appropriately bounded.
Build a source register around individual claims
Start with the claim, not a list of websites. Record the exact sentence the page is intended to support, the source title and URL, and the location of the supporting passage. Add the relevant scope: product version, market, observation period or research population. A reviewer should be able to understand why that source belongs beside that statement.
The World Wide Web Consortium's provenance overview describes the subject this way:
entities, activities, and people
W3C: PROV Overview; accessed 2026-09-12
In practical publishing terms, provenance means keeping enough information to retrace how a statement reached the page. A source may support a narrow factual claim while the surrounding paragraph contains the author's recommendation. Mark that distinction in the review record so later editors can preserve the evidence without inheriting an unsupported interpretation.
For a product comparison, separate the manufacturer's specification from your explanation of when it matters. If the specification changes, update the affected fact and review the recommendation. A register organized by claim makes it easier to find the pages that depend on the old value.
Check both identity and the supporting passage
A working URL establishes access to a page; it does not establish that the page supports the sentence. Read the relevant passage and confirm its subject, date and measurement scope. Check whether a quoted statement belongs to the article's author, an interviewee or another source cited within the article. Preserve that attribution in the public wording.
Crossref describes its metadata service as follows:
exposes the scholarly metadata
Crossref: REST API; accessed 2026-09-12
For sources that have registered identifiers, bibliographic metadata can help confirm the title, author and publication record. Use that information as an identity aid, then read the actual work for the claim. The existence of an identifier or metadata record does not turn a broad source into evidence for every statement about its topic.
The review record should capture:
- The claim and the passage that supports it.
- The source's identity, publication context and applicable version.
- The owner's decision to retain, revise or replace the claim.
Put a readable attribution beside a short quotation
Use a short quotation when the source's exact wording matters to the explanation. Give it a visible source title and a link to the supporting page. Keep the quotation distinct from your own prose. A reader should be able to identify who said it and follow the link without searching through an unrelated reference list.
For a multilingual page, retain the source quotation accurately and explain its relevance in the page's language. If you provide a translation, label it as a translation and preserve the original in the review record. Avoid silently presenting a paraphrase as the source's exact words.
The quotation should serve a purpose within the argument. It may define a technical term or establish how a source describes its research. Follow it with the practical implication for the reader's decision. That makes the attribution useful as evidence, rather than a decorative feature added at the end of the article.
Make updates part of the content owner's routine
Assign responsibility for checking sources when a product, policy or page changes. The update owner should review the claim, the source location and the internal links that lead readers to the explanation. Where a source has changed materially, preserve the earlier review record and document why the public sentence was revised.
Before completing a redesign handoff, inspect:
- The answer on the destination page and the route from related product pages.
- The source links and the identity of the cited works.
- The original and repeated engine observations, with the environments recorded.
Use the comparison to choose the next investigation. A repaired page route is a concrete website result. A changed engine answer is a separate observation to document. Keeping both records helps the team maintain useful content through future redesigns and source updates.
