How often should old content be reviewed to avoid losing timeliness in search results
How often should old content be reviewed to ensure it does not lose relevance in search results? Depending on the category: answer pages and pages without dates are reviewed quarterly, data pages are updated according to the source, historical content can be extended to more than half a year. The bottom line given by third-party standards is that important content should be refreshed at least every three months, and what is more important than 'how often' is 'which layers of review should be changed' - only refreshing the date does not count as a review, and changing the wrong things can even be an accident.
Review cycle by page value segmentation
| Page tier | Typical example | Suggested cycle | Signal to trigger strictness |
|---|---|---|---|
| Referenced answer page | Comparison, steps, specifications explanation | Each quarter | Monitoring found missing references |
| Page with numbers | Price, parameters, quotas | From the source | The source releases a new policy |
| Long-tail definition page | Definition of nouns | Half a year | New page squeezing on the same topic |
| Archive category | Version record, activity page | One year or not moving | None |
The basis for classification is not the release date, but whether this page still plays the role of 'the answer to the question'. The method of judgment returns to the keyword library: in the library, each word records the carrying page and the latest review date, which old pages are still being asked, and which have expired, check the library once and there is a list.
The content to be revised in one review, four layers
The first layer is facts and numbers: interface parameters, price, version number, this layer is wrong and the whole article is scrapped. The second layer is口径expression: old expressions (such as offline features) should be replaced whole sentence, not just add a patch of 「up to a certain year」. The third layer is link structure: whether the page pointed to by the internal link is still there, and whether the anchor text matches the new title. The fourth layer is meta information: time-sensitive words in the title, description, and tags (such as「latest」「this year」) are the easiest to expire, and they should be prioritized during the review.
What is suitable for full-site replacement and what is not suitable
It cannot do without tools like full-site replacement for batch review: column name adjustment, unified rewriting of old product names, and batch correction of invalid internal links can all be done in one go. But it is only suitable for 'deterministic replacement at the string level' and not for changing factual conclusions - for example, changing an old performance statement to a new standard is essentially rewriting rather than replacing, and must be done manually page by page. The fixed actions before full-site replacement: first make a backup, run the replacement rules in the test database first, and confirm that the hit range meets expectations before going to the formal database.
Draft and pending release status make review controllable.
The review is not to push the changes directly online all at once. The value of the document status divided into formal, draft, pending release, and recycling station processes lies here: the changes are first drafted, and checked against the source one by one; after verification, they are transferred to pending release and scheduled to take effect during the low traffic period; if there is a problem with the batch replacement, the changed page can still be rolled back as a whole, and the deleted old versions can also be retrieved from the recycling station within a retention period. Searching for referenced sites by month perfectly embeds the review rhythm into monthly actions: review the list of references at the end of the month, draft at the beginning of the month, and release in the middle of the month.
Common questions
Should the old articles be marked with the update date after the revision?The date of substantial modification is more conducive to timeliness judgment than the date of first release, but be honest: correcting typos is not worth changing the date.
What should be done if there is no full-time operator and the review cannot be completed?Narrow the scope by tier: only ensure the quarterly review of the cited answer pages and pages with numbers, the rest can be put aside first, which is better than complete waste.
Will the site-wide replacement hurt the semantics of the main text?Yes, that's why it is required to run the test library first; write the replacement rules as long matching strings with context, do not use short words like two or three characters for global replacement.
