Zhihe GrowthEven evergreen GEO articles age: platform rules change, models are discontinued, certificates expire, and case-test definitions evolve. Begin with what changed, then identify affected body text, FAQs, Schema, sitemaps, sources, and test questions, rather than merely changing the displayed date.
Which changes need to be recorded publicly
| Change Type | Page Action | Public log detail |
|---|---|---|
| Company/product facts | Verify approved facts, then update every page using them | Old/new facts and applicable date |
| Platform rules | Check official documents against effective time | Affected articles and operational guidance |
| Case metrics | Lock platforms, question sets, denominators and stages | New values and definitions that are not directly comparable |
| Unavailable or expired source | Find original or equivalent sources and narrow conclusions where necessary | Replaced source and change of conclusion |
| Layout or typo | Fix Pages and Test | There's no need to pretend to be a major research update. |
A page's dateModified should reflect meaningful content revisions; the sitemap's lastmod should also reflect actual changes. Google's sitemap guidance uses lastmod to help identify changes, without promising immediate recrawling. Setting every URL's modification date to today obscures real changes and undermines its maintenance value.
Responding to unavailable sources
Determine whether the source moved, was withdrawn, became restricted, or was superseded. For a move, verify and use the new official URL. For a withdrawal, reassess the claim and remove or narrow it if support is missing. Do not replace a vanished republication with unrelated marketing copy. Retain internal evidence versions for high-risk figures while exposing only authorized verification information.
Replacing a source is more than swapping a URL. Recheck the passage, referenced images or tables, and FAQs for obsolete wording, then test Schema and internal links. If AI previously used the content, retest the original questions for persistent old answers. The site cannot control platform revisit schedules.
Zhihe Growth's public maintenance process
Zhihe Growth's Update Log records material website updates for customers and search systems; the Editorial policy explains corrections. Current industry topics are published separately in the Insights section. If a development changes an evergreen conclusion, revise the original guide instead of repeating the answer in ten news posts. The two named project case studies must retain their respective current stage-specific citation definitions. Archive historical reports internally, but do not combine incompatible old and new figures into a growth multiple.
Zhihe Growth can maintain an impact table covering original sources, affected URLs, fact owners, revision dates, retest questions, and results. Customers can understand why changes were made, while readers see the final conclusions. Publish only approved, verifiable partnership and credential information. Partner logos, accepted patent applications, and official certifications remain separate categories.
Monthly Checklist
Each month, sample high-traffic and high-risk pages for source access, web/PDF numeric agreement, outdated FAQs, JSON-LD consistency, and current canonicals and sitemap URLs. Review change-prone platform guidance quarterly. Monitoring identifies issues; fact owners still approve substantive revisions. If nothing changed, retain the original date rather than inventing an update.
