Content Maintenance: The Aging Site Guide
Great pages don't stay great. Traffic decays slowly, competitors catch up, and facts go stale. This guide is the maintenance system: catch the decline early, then decide whether each page gets refreshed, merged, or pruned.
The Maintenance Loop
Maintenance is a loop, not a one-time cleanup: spot decline, decide a fate, act, then re-check. Find where you are below. Each stage links to a detailed guide.
Spot the Decay
Content decay is a slow bleed that a single dashboard snapshot hides. Google Search Console makes it visible when you compare a page's clicks across two equal periods months apart. A page losing a few percent a month is decaying, even while the overall site looks flat.
Why You Miss It
Site-wide totals mask individual decline. New pages add traffic while old pages steadily shed it, and the net looks stable. Catching decay means watching pages, not just the homepage number.

Decide the Fate
Every aging page has one of four fates, and one question picks it: does the page still have residual search demand worth saving? Refresh what slipped but still gets impressions. Merge pages that compete. Delete, with a redirect, what has no demand and no purpose.
The Four Fates
- Refresh: still earns impressions, slipped in position or went stale
- Merge: overlaps another page targeting the same query
- Prune: no impressions, no links, no strategic role
- Leave: stable and performing — don't fix what works

Refresh on a Cycle
A six-month re-optimization cycle keeps your winners winning: revisit your top-earning and top-impression pages twice a year, before a competitor publishes something fresher. The calendar sets the rhythm; the GSC data sets the priority.
What a Refresh Touches
Update the dated facts and stats, tighten the title and opening answer, add anything the query now expects, and re-check internal links. A refresh is faster than a new post and often lifts a page more, because the page already has history with Google.

Prune and De-Conflict
Cutting thin, dead pages can raise the pages that remain, because crawl attention and topical authority concentrate instead of spreading thin. The related fix is de-conflicting pages that fight each other for the same query — keyword cannibalization that splits your own authority.
Prune Without Losing Equity
Redirect a pruned URL to the closest relevant page rather than returning a 404, so any inbound links keep their value. For two pages splitting one query, merge them or set a canonical so one page carries the full signal.
How Brass-SEO Helps
Brass-SEO reads your Google Search Console and Google Analytics data and flags pages that are declining before the drop turns severe, through the Brass-SEO Declining Pages view. Maintenance becomes a short list of pages to act on instead of a manual audit of the whole site.
Turn Decay Into a To-Do List
Ask the chat "which pages lost the most traffic this quarter?" and get named pages, or open the Brass-SEO Declining Pages view directly. Both accounts connect through read-only OAuth. Setup takes about two minutes.

What is content decay?
Content decay is the slow decline of a page's organic traffic as it ages, competitors publish fresher pages, and its information goes stale. It rarely shows in a single snapshot because the drop is gradual. GSC reveals it when you compare a page's clicks across two equal periods months apart.
Should I update, merge, or delete an old post?
Update a page that still gets impressions but slipped or went stale. Merge pages that target the same query and split each other's authority. Delete, with a redirect, a page with no impressions, no links, and no purpose. The verdict depends on residual search demand worth saving.
How often should I refresh my content?
A six-month re-optimization cycle for important pages works well: revisit top earners and top-impression pages twice a year. Time-sensitive content needs more frequent checks; evergreen fundamentals can go longer. The trigger is data, not the calendar alone — refresh when GSC shows a page slipping.
Can deleting pages actually improve SEO?
Yes. Removing thin, outdated, or duplicative pages can lift the rankings of the pages that remain by concentrating crawl attention and authority. Prune correctly: redirect deleted URLs to the closest relevant page rather than returning 404s, so you keep link equity.
What is keyword cannibalization?
It happens when two or more of your pages target the same query, so they compete and split the clicks, links, and authority that should concentrate on one. Find it in GSC by checking whether multiple URLs rank for the same query. The fix is usually to merge the pages or set a canonical.
