Start with the confirmed update, not the rumour
A Google link spam update is not a diagnosis for every traffic decline. Before changing your backlink profile, confirm whether Google announced an update, establish what changed on your own site, and check for a manual action.
Editorial correction: an earlier version of this page described an unsupported January 2026 rollout and included unsourced impact percentages and detection mechanisms. Those claims have been removed. This guide explains a diagnostic process; it does not claim access to Google's internal systems.
Use Google's Search Status Dashboard for announced rollout dates and its spam policies for the conduct covered by those policies. A date overlap alone does not establish why a particular page lost visibility.
For the broader framework, start with our backlink quality hub and backlink audit process.
Separate three different situations
| What you can observe | What it establishes | Useful next action |
|---|---|---|
| A notice in Search Console's Manual Actions report | Google has identified a specified issue affecting your property | Read the notice, investigate its scope and document remediation |
| Rankings or clicks decline during an announced rollout | The two events overlap in time | Compare affected pages and queries; investigate other changes |
| A third-party tool assigns a high risk score | That provider's model flagged a pattern | Inspect the actual linking pages before deciding what to do |
Google documents manual actions and the review process. An automated ranking change and a manual action are different situations. Do not tell a client they have a penalty because an external score changed.
Build an incident timeline
Record the earliest visible change, the reporting timezone and the affected property. Then add website deployments, URL changes, canonical changes, robots changes, analytics changes and confirmed Google announcements.
Compare like with like: the same country, device, search type and query group. A fall in branded searches may have a different explanation from a fall across an informational topic. Falling clicks with stable impressions also deserves a different investigation from pages disappearing from search altogether.
A useful investigation sheet contains:
- The affected URL and its current final destination.
- The query group and date range being compared.
- Clicks, impressions and position, with the filters recorded.
- Indexing evidence available to the site owner.
- Relevant technical or content changes.
- A hypothesis, supporting evidence and a next check.
Keep a hypothesis separate from a finding. “The page redirects to an unrelated category” is observable. “SpamBrain penalised this page” generally is not.
Rule out technical losses first
Open the affected pages and check response status, canonical destination and indexing directives. Investigate accidental redirects, missing content and changes to internal navigation. Use the crawlability audit for a bounded public-page check and Search Console for information available to the verified owner.
If URLs moved, work through the backlink migration guide. A valuable old link pointing to a deleted URL is a concrete repair opportunity regardless of update timing.
Review link practices against the actual policy
Focus on how links were obtained and why they exist. Google's link spam policy covers practices intended to manipulate rankings, including buying links for ranking purposes and excessive exchanges. Advertising links can be qualified with appropriate attributes; a paid placement should not be sold as guaranteed ranking credit.
Inspect examples from each acquisition method rather than treating every low-metric domain as spam. Read the source page, identify the audience, check the destination and review any commercial relationship. Our placement verification checklist gives you a repeatable record.
For an agency-managed campaign, request the source URLs and acquisition method. An invoice that says “high authority links” is not sufficient evidence of editorial quality.
Choose a proportionate response
Stop an ongoing practice that violates the policy. Where you control an inappropriate paid link, correct the qualification or remove it. Where another publisher controls it, document the request and response.
Do not mass-remove useful links simply to improve a third-party risk score. Likewise, do not upload a disavow file as a routine reaction to volatility. Read the applicable Google guidance and investigate the actual circumstances before taking that step.
If a manual action requires a review request, describe the issue, the work completed and the evidence. Avoid claiming that traffic has recovered before the data supports it.
Measure the repair without promising recovery
Track the technical correction separately from search performance. A fixed redirect can be confirmed immediately; search systems revisiting and reevaluating pages is a separate process. Preserve the incident log so another change does not get mistaken for the result of your link work.
Report what is known: affected pages fixed, questionable practices stopped, requests sent and current search trends. There is no responsible universal recovery date or percentage to promise.
