The magnitude of a content update is the amount and importance of what changes. Replacing a false price may involve three words but prevent a serious misunderstanding. Adding a thousand words can leave the customer’s original problem unresolved.
There is no required rewrite percentage
Google’s people-first content guidance favours meaningful value over changes made to appear fresh. It does not publish a percentage of text that must change for a ranking benefit. Separate volume from consequence: correcting a prerequisite, adding a missing comparison or documenting a limitation can matter more than rewriting an introduction. The right scope starts with a specific defect, not a content tool’s target.
Write an update brief before editing
List the current page’s purpose, the questions it should answer and the evidence that something is missing. Record obsolete facts, weak explanations and unsupported claims separately. Protect accurate material that still helps readers. Compare the proposed version against the original brief, including images, downloads and metadata. This creates an editorial audit trail and makes it easier to explain why the change was worth undertaking.
Release and evaluate a coherent change
Keep the established URL when the page still serves the same search intent. Check that headings, page title, internal links and any structured data agree with the revised content. Record the release date and review relevant query groups after Google has had time to process it. An SEO audit can help separate content weaknesses from technical barriers that rewriting would leave untouched.
Protect the reasons behind the revision
Keep a change log that names the reader problem, the material changed and the evidence checked. Include screenshots or downloads that an editor might otherwise overlook. If the revision changes the offer itself, involve the person responsible for delivering it. This record helps distinguish a content correction from a commercial change and allows later analysis to consider both, instead of interpreting every movement as a freshness effect.
A service comparison example
Suppose a Perth IT provider’s backup guide describes restoration but omits how often restoration is tested. A useful update could add a practical testing checklist, explain who signs off results and clarify the limits of the example. Rephrasing every other paragraph would be unnecessary. Evaluate whether readers can now compare options and make a qualified enquiry. Search changes may also reflect competitors, seasonality or other releases, so do not attribute every movement to the edit.
Common questions
Will changing half a page make it rank higher?
No published Google rule sets that threshold. Improve the parts preventing the page from answering its intended question.
Should old paragraphs always be removed?
No. Retain accurate explanations that remain useful, and change or remove material for a documented reason.
Terms in this guide
- Search intent — The task or question behind a search, such as learning a concept, comparing options or finding a provider. Content should answer the intended need.
