The short answerContent decay is a loss of usefulness or competitiveness over time; seasonality is a recurring change in demand. A falling traffic line does not identify the cause. Compare query and page evidence, similar periods and site changes before deciding the article needs a rewrite.

Locate the first observable change

Separate fewer impressions from weaker click-through and fewer conversions after arrival. A page receiving similar impressions but fewer clicks presents a different question from one disappearing from eligible search results.

Check indexing, redirects, canonical changes and availability before editing the prose. Use the actual property and reporting definitions. Analytics sessions and Search Console clicks are not the same measure.

These are hypotheses, not automatic diagnoses. More than one cause can be present.

Worked example: a seasonal article drops after its peak

Illustrative example: a promotion-planning guide receives fewer searches after the relevant shopping period. Changing its date and adding generic paragraphs does not create seasonal demand. Review whether the guide still answers the next useful planning task and whether historical demand shows a comparable pattern.

If a product process changed, however, the article may need a substantive refresh regardless of the season. Update the actual steps and evidence, not only the headline year.

Choose the smallest justified action

Repair a technical blocker when the page is inaccessible. Refresh outdated facts when the task changed. Improve the title or answer when query evidence shows an intent mismatch. Maintain useful content when the decline reflects temporary demand rather than deterioration.

Record the baseline, change and observation period. Do not claim the update caused improvement merely because traffic rose later. The content refresh guide provides a process for changes supported by evidence.
