Google Search Advocate John Mueller has clarified that core updates are based on long-term data patterns, not recent site changes or link spam attacks.
This insight was shared during a public discussion on Bluesky, where SEO experts debated the impact of spammy backlinks on rankings during a core update.
Mueller’s comments provide clarity as Google rolls out its June core update.
Core Updates and Link Influence
When asked if recent link spam affects core update evaluations, Mueller responded:
“Off-hand, I can’t think of how these links would play a role with the core updates. It’s possible there’s some interaction that I’m not aware of, but it seems really unlikely to me.
Also, core updates generally build on longer-term data, so something really recent wouldn’t play a role.”
This suggests that recent spam links are unlikely to affect site evaluations during a core update.
Link Spam and SEO Concerns
The discussion began with SEO consultant Martin McGarry, who shared data indicating spam attacks on high-value keywords.
In a post referencing a SEJ article, McGarry noted:
“This is traffic up in a high-value keyword and the blue line is spammers attacking it… as you can see traffic disappears as clear as day.”
Mark Williams-Cook replied that links are often not the root cause of visibility loss, even when timing appears suspicious.
Google’s Disavow Tool
Discussing mitigation strategies, Mueller reminded the community about Google’s disavow tool, though it’s not always necessary.
“You can also use the domain: directive in the disavow file to cover a whole TLD, if you’re +/- certain that there are no good links for your site there.”
He added that the tool is often misunderstood or overused:
“It’s a tool that does what it says; almost nobody needs it, but if you think your case is exceptional, feel free.
Pushing it as a service to everyone says a bit about the SEO though.”
Calls for Transparency
Alan Bleiweiss urged Google to share more data on how many domains are ignored algorithmically:
“That would be the best way to put site owners at ease, I think. There’s a psychology to all this cat & mouse wording without backing it up with data.”
This reflects a common desire for more clarity on how Google manages low-quality links.
Key Takeaways
Mueller’s insights are valuable for understanding core updates:
- Recent link spam is unlikely to affect core updates.
- Core updates rely on long-term data, not short-term changes.
- The disavow tool is available but rarely needed.
- Google may already discount low-quality links automatically.
If you notice visibility changes since the June core update, focus on long-term factors like content quality, site structure, and overall trust. Consider leveraging SEO and social media marketing strategies with Cyberset for better results.
