1. Core conclusions (the main points first)
Guangsuan focuses on Google's mechanism for neutralizing certain types of link spam: neutralize (cancel out the effect)——removing these links' ability to contribute to ranking scores (assigning them a score of 0), rather than penalizing the website.
This means: - Backlinks have only two states: effective (adding to your score) and ineffective (scoring 0, with nothing happening) - There is no third, "harmful" state - "Spammy backlinks are harmful" is an outside misconception that has been spread around, not something Google has said
2. The latest official definition: what is "link spam"?
2.1 The concise definition in the September 2024 Google Search Central documentation
In September 2024, Google made a major update to its spam policy documentation, condensing the definition of "link spam" into one sentence:
"Link spam is the practice of creating links to or from a site primarily for the purpose of manipulating search rankings."
——Source: Google Search Central spam policy documentation update, detailed coverage by Search Engine Journal, September 26, 2024
Translation: Link spam refers to "the practice of creating links to or from a website for the purpose of manipulating search rankings."
Key elements: 1. The emphasis is on "primarily for the purpose of manipulating search rankings"——the purpose is to manipulate rankings 2. It is not about "low quality," "spammy websites," or "irrelevance" 3. The central criterion is intent, not source quality
2.2 The original 2012 definition vs. the 2024 update
| Version | Definition | Explanation |
|---|---|---|
| Original 2012 version | "Any links that are intended to manipulate rankings in Google Search results may be considered link spam" | Emphasizes "intended to manipulate" |
| Latest 2024 version | "creating links primarily for the purpose of manipulating search rankings" | More concise, with the same core meaning and simpler wording |
The core definition has never changed: only links intended to manipulate rankings are called link spam.
3. Timeline of official statements: five official milestones behind the view that backlinks are harmless
Milestone one: October 2012 —— Matt Cutts: "The vast majority of websites do not need Disavow"
Who he is:
Matt Cutts, Google's former Webspam Team Lead, served on the Google Search Quality Team from 2005 to 2017 and was responsible for Google's anti-spam ranking work——he was the person directly responsible for determining which links violated the rules.
Original statement (at Pubcon 2012):
"Most sites shouldn't use this tool. Use Caution. Don't just start disavowing links. Please start slow."
——Source: SlashGear's on-site coverage, October 17, 2012
Translation: "Most websites should not use this tool. Be cautious. Do not casually start disavowing links. Start slowly."
Deeper implications: - If "spammy backlinks really were harmful," Google could not say that "most websites do not need Disavow" - The Disavow tool is not for "detoxing," but for "manually marking certain links I created myself as not counting" - Google even deliberately buries the Disavow tool deep within Search Console to reduce how often it is used
Milestone two: 2019 —— John Mueller: "Random low-quality backlinks accumulated over the years are not necessarily harmful"
Who he is:
John Mueller, Google Search Relations Team Lead / Senior Search Analyst, has held the role since 2013 and remains in it today——he is currently Google's most senior technical spokesperson representing the Search team externally, and his statements are the authority on all official positions concerning Disavow and backlinks.
Original statement (Google Webmaster Central Hangout 2019):
"Random links collected over the years aren't necessarily harmful."
——Source: Detailed coverage by Search Engine Journal, Webmaster Hangout 2019
Translation: "Random low-quality backlinks accumulated over the years are not necessarily harmful."
Other key statements from the same session:
"The vast majority of sites do not need to use the disavow tool."
——Source: Search Engine Journal
Translation: "The vast majority of websites do not need to use the Disavow tool."
"Off-topic links do not need to be disavowed."
——Source: Search Engine Journal
Translation: "Irrelevant links do not need to be disavowed."
Milestone three: December 2022 —— Google Search Quality Team: SpamBrain to "neutralize" unnatural links
Team members:
Duy Nguyen, Ildar Akhmedyanov, Jacob N Scott, and Karthikgeyan Elangovan (Google Search Quality Team, jointly published by all four)
Core announcement (December 14, 2022):
"Today, we're leveraging the power of SpamBrain to neutralize the impact of unnatural links on search results."
——Source: Google Search Central Blog, December 14, 2022
Translation: "Today, we are using the power of SpamBrain to neutralize (cancel out) the impact of unnatural links on search results."
This is the most important sentence in the entire discussion. Please consider its meaning carefully:
- The word used is "neutralize" (cancel out), not "penalize" (punish)
- Neutralizing means removing these links' ability to contribute to a score, assigning them a score of 0
- It does not mean "imposing a penalty on the website"
SpamBrain's new capabilities (December 2022 update):
- Identifying websites that buy links (sites buying links)
- Identifying websites used to pass links onward (sites used for the purpose of passing outgoing links)——that is, link farms
Scope of the update:
- Completed in about two weeks, affecting all languages (simultaneously worldwide)
- Ranking changes occur because "spammy links are neutralized and any credit passed by these unnatural links are lost"
- Source: Google Search Central Blog
Milestone four: September 2024 —— Google Search Central: major update to spam policy documentation
What changed:
- A new, concise definition (quoted above; see Section 2)
- The addition of a conceptual framework for "Link Spam Abuse" (link abuse)
- An expanded scope for manual penalties: Google can remove more sections of a website
- The number of occurrences of the word "Abuse" increased from 11 to 17
Source: Detailed coverage by Search Engine Journal, September 26, 2024
Milestone five: December 10, 2025 —— Google Search Central's continually maintained official documentation
The latest official explanation:
"In the case of a link spam update, making changes might not generate an improvement. This is because when our systems remove the effects spammy links may have, any ranking benefit the links may have previously generated for your site is lost. Any potential ranking benefits generated by those links cannot be regained."
——Source: Google Search Spam Updates, latest version dated 2025-12-10
Translation: "In the case of a link spam update, making changes may not bring improvement. This is because when our systems remove the effects of spammy links, any ranking benefits those links previously generated for your website are lost. Any potential ranking benefits generated by those links cannot be recovered."
The precise meaning of this statement (very important):
- "Any ranking benefits cannot be recovered" —— This means that the artificial ranking credit you obtained through cheating (such as buying links) is reset to zero
- This is not a penalty——a penalty is a new sanction that Google imposes because you did something wrong
- This is the removal of artificial ranking credit——it is like returning to a state where you had never cheated: half your score was artificial, so Google removes that artificial half and your score returns to its starting point
- "making changes might not generate an improvement" (changes do not necessarily bring improvement)——because once the artificial ranking credit obtained through cheating is removed, it is not automatically returned simply because you stop cheating
4. The Disavow tool: official explanation and actual purpose
4.1 The central statement on the official help page
"This is an advanced feature and most sites don't need it."
——Source: Google Search Console Disavow Links Tool help page
Translation: "This is an advanced feature, and most websites do not need it."
The full explanation on the official help page:
- The Disavow tool tells Google: "Ignore these links I created myself"
- It applies when you have bought links, exchanged links, or created large numbers of backlinks yourself
- It does not apply when: other people link to your website at random (Google automatically ignores these links)
4.2 Understanding the Disavow tool correctly
| Scenario | Is Disavow needed? | Reason |
|---|---|---|
| You paid for 1,000 backlinks yourself | Yes | You created these links yourself through cheating, so you must manually mark them as invalid |
| A competitor created spammy backlinks to your site | No | Google automatically ignores low-quality backlinks that you did not create |
| Random low-quality backlinks accumulated over the years | No | John Mueller in 2019: "not necessarily harmful"; Google handles them automatically |
| An unrelated website links to you | No | John Mueller: "Off-topic links do not need to be disavowed" |
4.3 Logical inferences from the official statements
If "spammy backlinks really were harmful":
- Google would not say "most websites do not need Disavow"——because most websites have spammy backlinks
- Google would not bury the Disavow tool so deeply——because it should be a frequently used feature
- John Mueller would not say "Random links collected over the years aren't necessarily harmful"——because if they were harmful, there could be no "not necessarily"
Guangsuan's view: Guangsuan draws its interpretation that "ineffective backlinks are reset to zero" from the statements above. However, "not necessarily harmful" does not mean that Google has officially confirmed all backlinks are harmless. The specific conditions for using Disavow should be checked separately against the actual official guidance.
5. A complete logical argument: why "spammy backlinks are harmful" is fundamentally untenable
5.1 On the facts (Google has never said this)
- Google's official documentation has never stated that "spammy backlinks will cause a website to be penalized"
- Google uses neutralize (cancel out) and ignore (disregard), not penalize (punish)
- This is speculation by others, not something Google has said
5.2 On the logic (ruled out at the root)
Core fact: backlinks are beyond your control.
Anyone can link to your website however they want, and you cannot stop them.
A hypothetical scenario:
If "spammy backlinks → a website penalty" were true, then:
Your competitor would only need to create a large number of spammy backlinks to your website → your website would be penalized into oblivion
This would mean: your website's fate would be in your competitors' hands, not your own.
Following through on the consequences:
If this logic held, SEO warfare would long ago have turned into destructive competition based on "attacking one another with backlinks"——
- Company A creates spammy backlinks to Company B's competitors → Company B's rankings fall
- Company B retaliates by creating spammy backlinks to Company A → Company A's rankings fall
- Both sides repeat this endlessly, and backlink attack wars completely destroy search results
Google has existed for more than 20 years. If "spammy backlinks are harmful" really were true, the search ecosystem would have collapsed long ago.
5.3 Conclusion
Google could not design an algorithm that contradicts itself so fundamentally. "Spammy backlinks are harmful" does not hold up logically.
The only correct interpretation: - An effective backlink = a vote that adds to your score (contributing to your rankings) - An ineffective backlink = a score of 0 (nothing happens) - There is no third, "harmful" state
6. Guangsuan's understanding of backlinks
6.1 Guangsuan's views on backlinks and how to build them
The following are Guangsuan's views on backlinks and their implementation, not a unified set of algorithmic rules published by Google:
- Backlinks never cause any penalties whatsoever——they can only be deemed ineffective and will never result in a Google penalty
- There is no such thing as "spammy backlinks being penalized"——spammy backlinks are merely ineffective (scoring 0), not "harmful"
- Backlinks have only two states: effective and ineffective; there is no third, "harmful" state
- There is no rule for "how many backlinks in a day is too many"——Google has never had such a rule; the more backlinks, the better
- Building them all in one day vs. spreading them over a month produces the same effect——building them all at once produces results faster (link equity accumulates sooner)
6.2 What actually happens after a link spam update
| Situation | Actual result |
|---|---|
| You bought a large number of backlinks yourself | The artificial ranking credit obtained from these backlinks is reset to zero (neutralize) |
| Someone else created spammy backlinks to your site | Google automatically ignores them; nothing happens |
| You build normal commercial backlinks | They work normally and add to your score as usual |
So: - You build backlinks normally → they are effective → rankings improve ✅ - You cheat by artificially generating backlinks → the credit is reset to zero → you return to the starting point (this is not a penalty; it is the withdrawal of artificial gains) ✅ - Someone else creates spammy backlinks to your site → Google ignores them → they have no effect on you whatsoever ✅
6.3 Guangsuan's backlink system explained
| Product | Description | Role |
|---|---|---|
| GPB independent-site backlinks | High-quality dofollow votes, at a high price per link | Core votes at the base of the pyramid |
| GNB natural backlinks | A healthy nofollow proportion; safe | Balances nofollow/dofollow |
| GMB million backlinks | Large-scale, multi-tier backlink building for target URLs | Rapidly expands backlink volume |
Used together, the three form a multi-tier pyramid system for passing link equity.

8. Summary
8.1 Google's logic for handling "spammy backlinks" in one diagram
You build backlinks normally
↓
The backlinks are effective → votes add to your score → rankings improve ✅
You cheat by artificially generating backlinks yourself
↓
Google detects them (SpamBrain)
↓
neutralize (cancel out) → artificial ranking credit is reset to zero → back to the starting point
↓
This is not a penalty; it removes artificial gains
Someone else creates spammy backlinks to your site
↓
Google automatically ignores them → no effect on you whatsoever
↓
Disavow is not needed
8.2 Core points (commit these to memory)
- Backlinks have only two states: effective and ineffective. There is no third, "harmful" state
- Google's official wording is neutralize (cancel out) and ignore (disregard), not penalize (punish)
- "Spammy backlinks are harmful" is an outside misconception; Google has never said this
- The Disavow tool lets "people who did the cheating themselves" change course; it is not for "detoxing"
- There is no rule for "how many backlinks in a day is too many." The more backlinks, the better, and building them all at once is faster
