A core update does not penalise a site. It re-evaluates which pages deserve to rank for a query and finds that some of yours no longer do. For a casino affiliate site built on thin comparison pages and bought links, that re-evaluation can take 40 to 70% of traffic in a weekend. This is the timeline of one recovery, month by month, with the part most case studies leave out.
Month 0: the drop
Two consecutive updates. Organic sessions −60% against the pre-update baseline, revenue per visit falling faster than traffic because the pages that survived were informational, not commercial. No manual action. Nothing in Search Console except the graph.
Month 1: the audit
- Which URLs lost, and to which competitors. In this case, three publishers with deeper topical coverage absorbed most of it.
- Link profile: several hundred domains from two marketplaces, an expired-domain network, and commercial anchor ratios no natural profile has.
- Content: four hundred pages, most answering one query badly; two GEOs translated rather than written; bonus terms out of date on a majority of top earners.
Months 1–2: the clean-up, and nothing improves
Disavow submitted. Sixty percent of URLs removed or consolidated with 301s. Fact-checking process built. The graph did not move. This is the period where most clients change agencies, and the period in which the recovery is actually decided. We told the client in month one that months one and two would be flat; that is the only reason we were still there in month three.
Months 2–5: rebuild by cluster
One GEO at a time, starting with the largest revenue line. Topical clusters around game types, payment methods and licensing rules, with pillar pages built to be the best result rather than a result. Native-language writers per market. Long-tail movement first, commercial terms later.
Months 4–8: links that look like a brand
Digital PR around data pieces, industry publications, partnerships — at a velocity matched to content output. Referring-domain growth that looks like a curve rather than a step.
Months 6–11: the numbers
- Sessions back above the pre-update peak on roughly 40% fewer URLs.
- Revenue per visit +92% against the pre-drop baseline, because the traffic that returned had commercial intent.
- Three core updates since; each flat or positive.
What this means for your site
- Recovery time is set by how much has to be removed, not by how much has to be added.
- The first two months are silent by nature. Plan for it, budget for it and tell the board.
- Do not rebuild the thing that dropped. Rebuild the thing the survivors have.
What to do on Monday
- Compare your lost URLs to the pages that replaced them in the SERP. The gap you find is the brief.
- Get the disavow in this week. Waiting for a manual action is waiting for a worse problem.
- Write down the month you expect to see the first movement, and share it with whoever signs the invoices.
