Find and fix content decay with Google Search Console and AI

Content decay happens when pages that once ranked well gradually lose visibility and clicks over months or years. It is one of the most common — and most ignored — SEO problems because the drop is slow enough that nobody notices until revenue has already fallen.

Google Search Console has all the data needed to detect decay early. Claude with GSC MCP can scan your entire content library, identify decaying pages, diagnose the cause, and suggest the exact fixes.

What causes content decay?

Outdated information — your 2022 guide is now outranked by a 2026 update
Increased competition — more sites published better versions of your content
Intent drift — what users mean by a query shifted and your page no longer matches
Algorithm changes — EEAT updates, Helpful Content changes
Internal neglect — no internal links added to the page, no new links earned

Detect content decay with Claude + GSC MCP

Connect Search Console to Claude via GenieSeo MCP, then run these checks.

Check 1: Period-over-period decline scan

Compare the last 90 days vs the 90 days before that for all pages on my site.
Find every page where clicks declined more than 20%.
Sort by absolute click loss (not percentage — a page losing 500 clicks matters more than one losing 50%).
Show: page URL, old clicks, new clicks, old position, new position.

Check 2: Year-over-year decay (the most reliable signal)

Compare May 2025 vs May 2026 (or the most recent 30-day period vs the same period last year).
Find every page where clicks fell more than 30% year-over-year.
These are my decaying pages — they were once healthy but are now in long-term decline.
List them sorted by click loss, largest first.

Check 3: Impression decline (early warning signal)

Impressions fall before clicks fall — they're an early warning.

Compare impressions for the last 28 days vs the prior 28 days, by page.
Find pages where impressions fell more than 25% but position changed less than 2 spots.
These pages are losing Google's attention — they will lose clicks soon if not addressed.

Check 4: Position creep (slow decline)

For my top 30 pages by clicks last year:
Compare their average position then vs now.
Find any page where position dropped more than 3 spots.
These are my slow-decline candidates — once strong, now sliding.

Check 5: Query loss (what topics am I losing?)

Compare the top 100 queries from 6 months ago vs the top 100 queries today.
Which queries appear in the old list but NOT in the current top 100?
I have lost these keyword rankings. What topics do these queries represent?

Diagnose the cause

Once you have a list of decaying pages, ask Claude to diagnose each one:

I have identified these pages as decaying (losing traffic over 6+ months):
[paste URLs]

For each page:
1. What queries was it ranking for? (use get_search_by_page_query)
2. What is its current average position for those queries?
3. Based on the query intent, what is the most likely reason for decay?
   (outdated content / increased competition / intent drift / thin content)
4. What is the specific fix? Give me a 3-point action plan per page.

Recovery framework

Claude will diagnose; you implement. Common recovery actions:

Cause	Fix
Outdated statistics or dates	Update data, add current year to title, refresh examples
Intent drift	Rewrite intro and H2s to match current search intent
Thin content	Add depth — original research, expert quotes, real examples
New competition with better content	Add a unique angle competitors don't have
Lost internal links	Find pages that should link to this content and add links

Recovery prompt (for a specific decaying page)

The page [URL] has lost 40% of its clicks over the last 6 months.
It currently ranks for these queries: [get from get_search_by_page_query]

Based on these queries and the traffic trend:
1. What intent are users searching for?
2. What is my page missing compared to what would rank for this today?
3. Write a new introduction (150 words) that better matches current search intent.
4. Write 3 new H2 subheadings I should add to deepen the content.
5. Suggest 2 new sections with data or examples I could add.

Prioritise your content refresh backlog

I have these decaying pages: [list URLs and their monthly click loss]
Given limited bandwidth to refresh content, prioritise them by:
1. Traffic potential (how much can I recover?)
2. Effort required (is it a light update or a full rewrite?)
3. Revenue impact (are these commercial or informational pages?)

Output a prioritised list with a recommendation: "refresh", "rewrite", or "consolidate/redirect".

Prevention: monthly decay scan

Make this a monthly habit:

Monthly content health check for [site]:
1. Show me the 10 pages with the biggest click decline this month vs last month.
2. Show me the 10 pages where position dropped more than 2 spots this month.
3. Flag any page that was in my top 20 by clicks 3 months ago and is no longer.
These are my content decay early-warning signals.
