Use when the user says \"/blog decay\", \"content decay\", \"traffic drop\", \"QoQ decline\", \"GSC decay\", or \"refresh declining posts\".\nargument-hint: \"<current-gsc.json> <previous-gsc.json> [threshold] [metric]\"\nuser-invokable: true\nlicense: MIT\n---\n\n# Blog Decay\n\nUse `/blog decay` to find pages whose Google Search Console performance has\ndeclined quarter-over-quarter. The command compares a current-period export\nagainst a previous-period export, flags pages with a 20% or larger decline by\ndefault, and recommends the next content action.\n\n## Default Offline Workflow\n\nRun the local analyzer against two GSC page exports:\n\n```bash\npython3 scripts/content_decay.py current.json previous.json\n```\n\nUseful options:\n\n```bash\npython3 scripts/content_decay.py current.json previous.json --threshold 0.30\npython3 scripts/content_decay.py current.json previous.json --metric impressions\npython3 scripts/content_decay.py current.json previous.json --format markdown --output decay-report.md\n```\n\nThe script accepts JSON lists of page rows with `page` or `url`, `clicks`, and\n`impressions`. It also accepts the object shape returned by `blog-google` when\nthe rows are under a top-level `rows` key.\n\n## Optional Live GSC Export\n\nFor live data, use `/blog google gsc` or the underlying `blog-google` command\nto create each period export, then run the offline analyzer:\n\n```bash\npython3 skills/blog-google/scripts/run.py gsc_query --property sc-domain:example.com --dimensions page --start-date YYYY-MM-DD --end-date YYYY-MM-DD --json > gsc-current.json\npython3 skills/blog-google/scripts/run.py gsc_query --property sc-domain:example.com --dimensions page --start-date YYYY-MM-DD --end-date YYYY-MM-DD --json > gsc-previous.json\npython3 scripts/content_decay.py gsc-current.json gsc-previous.json --format markdown\n```\n\nUse adjacent periods of similar length for short-term checks. For seasonality,\nalso run a year-over-year comparison using the same date length, filters, search\ntype, device, country, and property. When possible, inspect up to 16 months of\nGSC history before diagnosing a traffic drop.\n\n## Decay Model\n\nThe default metric is `clicks`. Also review impressions, CTR, average position,\nquery and page pairs, device, country, and search appearance deltas before\nchoosing an action.\n\nSeverity:\n\n| Decline | Severity |\n| --- | --- |\n| 20% to 39.9% | warning |\n| 40% to 59.9% | high |\n| 60% or more | critical |\n\nDropped pages are previous-period pages missing from the current export only\nafter confirming identical filters, sufficient row limits, matching dimensions,\nand URL inspection. Otherwise mark them as `needs_validation`, not\n`dropped_out`.\n\n## Recommended Actions\n\nUse the action as the first triage path only after checking indexation,\ncanonical status, query loss, internal links, backlinks, seasonality, and\nbusiness value:\n\n| Action | Use when |\n| --- | --- |\n| refresh/update content | The page still has demand and likely needs freshness, title, internal link, or section updates. |\n| investigate query shift | Clicks fell while impressions held up, suggesting CTR, rank, SERP, or query mix changes. |\n| consolidate/redirect | The page dropped out or the loss is severe enough that merging into a stronger URL may recover value faster. |\n| prune | The page had very low prior demand and may not justify rewrite effort. |\n\n## Cross-references\n\nUse `blog-google` to collect Search Console exports when live credentials are\navailable. Use `blog-rewrite` after decay detection when the recommended action\nis refresh/update content and the page is worth improving.\n","tagline":"Detect content decay from Google Search Console exports by comparing current and previous page performance, flagging quarter-over-quarter traffic drops, dropped pages, and refresh, consolidate, prune, or query-shift actions.
