Spam Policies for Google Web Search

Google Search Central. Spam policies documentation.

Brass-SEO treats this as the canonical definition of what Google counts as spam. Three policies added in 2024 anchor the current rules. Scaled content abuse is generating many pages primarily to manipulate rankings rather than help users. Site reputation abuse is publishing third-party content on a host site mainly to exploit ranking signals the host earned from its own first-party content. Expired domain abuse is buying an expired domain and repurposing it to manipulate rankings with low-value content. The operative test across all three is intent to manipulate plus low user value — not the tool or method used to produce the content.

Examines:
Google's spam policy documentation — the current definitions of scaled content abuse, site reputation abuse, and expired domain abuse.

March 2024 Core Update and New Spam Policies

Google Search Central Blog. March 2024.

Brass-SEO cites this for the origin and timeline of the current spam policies. Google's March 2024 announcement introduced the three new policies — expired domain abuse, scaled content abuse, and site reputation abuse — and set the site reputation abuse policy to take effect on May 5, 2024, giving publishers about two months of notice. Google stated that sites violating these policies may rank lower or not appear at all. The announcement also drew a line Brass-SEO keeps in its copy: the spam policies launched alongside, but separate from, the March 2024 core update, which is a quality update rather than a manipulation-enforcement action.

Examines:
Google's March 2024 announcement of three new spam policies and the May 5, 2024 effective date for site reputation abuse.

New Updates to Address Spam and Low-Quality Results

Tucker, Google. The Keyword, March 5, 2024.

Brass-SEO uses this for Google's own measure of the crackdown's scale. Elizabeth Tucker, a Google Search product director, wrote that Google expected the March 2024 update and its prior efforts to together reduce low-quality, unoriginal content in search results by 40%, and a later note reported the actual reduction came in higher, around 45%. The post names the same three spam policies. Brass-SEO cites the 40% figure straight from Google rather than the many secondhand versions, and uses it to show users that the manipulation crackdown was large and measured, not a rumor.

Examines:
Google's consumer announcement of the March 2024 update, including the expected 40% reduction in low-quality content and the three named spam policies.
Brass-SEO draws on:
The 40% (later about 45%) reduction figure — cited as the primary-source scale of Google's 2024 spam enforcement.

Updated Site Reputation Abuse Policy

Google Search Central Blog. November 2024.

Brass-SEO cites this as the current state of the site reputation abuse rule. Effective November 19, 2024, Google clarified that using third-party content to exploit a host site's ranking signals violates the policy regardless of whether the site owner is involved in or oversees that content. The update closed the loophole from the March wording, which had implied that first-party editorial oversight could exempt so-called parasite SEO sections. Enforcement runs through manual actions with Search Console notifications. Brass-SEO flags coupon, deals, and sponsored subdirectories on otherwise-authoritative domains as manual-action risk on this basis.

Examines:
Google's November 2024 update to the site reputation abuse policy — removing the first-party-oversight exemption, effective November 19, 2024.

How We Fought Spam on Google Search in 2022

Google Search Central Blog. April 2023.

Brass-SEO uses this to show why manipulation shortcuts fail: enforcement is automated and scaling. Google's 2022 webspam report states that SpamBrain, its AI-based spam-prevention system launched in 2018, detected five times more spam sites in 2022 than in 2021, and that its work helped keep more than 99% of searches free of spam. The report notes SpamBrain detects both sites buying links and sites used to pass outgoing links. Brass-SEO cites the 99% figure to explain to users that automated detection now outpaces the tactics, so manipulation is a shrinking bet.

Examines:
Google's annual webspam report — SpamBrain's 2022 detection scale and the figure that Google kept more than 99% of searches spam-free.

The SpamBrain 5x-detection and 99%-spam-free figures — cited when Brass-SEO explains that automated enforcement makes manipulation unreliable.

Frequently Asked Questions

What are the three spam policies Google added in 2024?

Scaled content abuse, site reputation abuse, and expired domain abuse. Scaled content abuse is generating many pages primarily to manipulate rankings rather than help users. Site reputation abuse is publishing third-party content on a strong host site mainly to exploit ranking signals that host earned from its own content. Expired domain abuse is buying an expired domain and repurposing it to manipulate rankings with low-value content. Google announced all three in March 2024.

Does using AI to write content violate Google's spam policies?

Not by itself. Google's scaled content abuse policy targets content produced primarily to manipulate rankings and that provides little value to users — the test is intent and value, not the production method. AI-assisted content that genuinely helps users is not a violation. Generating large volumes of low-value pages to game search is, whether a human or a model wrote them.

What is site reputation abuse (parasite SEO)?

It is publishing third-party content on a host site mainly to exploit the ranking signals that host earned from its first-party content — for example, a coupon or sponsored-content subdirectory riding a reputable domain's authority. Effective November 19, 2024, Google clarified that this violates the policy regardless of whether the site owner oversees the content, closing an earlier oversight loophole. It is enforced through manual actions.

How does Google enforce its spam policies?

Through a mix of automated systems and manual actions. SpamBrain, Google's AI-based spam-prevention system launched in 2018, detected five times more spam sites in 2022 than in 2021 and helped keep more than 99% of searches spam-free. Some policies, such as site reputation abuse, are enforced through manual actions with notifications in Google Search Console. Sites in violation may rank lower or be removed from results.
