Spam Updates
A rival plant shop shot to the top of the results last year on the back of hundreds of cheap guest posts. Within days of a spam update it slid off the first few pages. Leafline, which had earned its links slowly, barely moved. Spam updates hit the sites that relied on breaking the rules.
The rule
Spam updates take back what tricks gave; only removing the tricks recovers.
Besides human reviewers, search engines run automated spam-detection systems, and they improve them regularly. A spam update is a notable improvement to those systems, sometimes focused on one kind of spam, such as manipulative links.
How the three kinds of change differ:
| Core update | Spam update | Manual action | |
|---|---|---|---|
| Who acts | Automated ranking systems | Automated spam systems | A human reviewer |
| Aimed at | Everyone's relevance and quality | Policy violations | One site's violations |
| Notice to the site? | No | No | Yes, in Search Console |
| Recovery | Improve usefulness overall | Remove the violations, then wait | Fix, document, request reconsideration |
Two effects are worth knowing:
- Neutralising. Link-focused spam updates often make bought or traded links simply count for nothing. A site that falls may not be "penalised" at all; it may have lost the fake support it was standing on.
- Slow recovery. After a site cleans up, automated systems need time, often months, to notice the change. And rankings that were built on violations do not come back, because they were never really earned.
The shortcut
When rankings fall during a spam update, audit yourself against the spam policies first. If you find a violation, fix it. If you find none, the spam update was probably not your cause, so look for other explanations.
Line up the dates
A 12% dip in clicks begins two days into an announced spam update.

Remember
- Spam updates take back what tricks gave; only removing the tricks recovers.
- Core update: everyone re-graded. Spam update: violations detected. Manual action: a human, with a notice.
- The trap: filing reconsideration requests for automated updates, or blaming a coincidental dip on one.
