Google Search refers to spam as activities that manipulate its search system to achieve high rankings. With spam policies, Google is improving the quality of search results, which will eventually give users a better experience. When you upload anything, whether it’s written content, images, videos, or web pages, always make sure to consider the spam policies to avoid penalties. It clearly says all web search results—including Google’s own platforms—must follow these policies.
Cloaking
Cloaking means showing search engines one version of a page and human visitors a completely different one to cheat search rankings. Even hackers can use cloaking to hack a site and make it really hard for the owner to detect.
Example:
Search crawlers receive a keyword-optimized text page (e.g., “cheap flights”) to rank highly, while human browsers get a page filled with affiliate ads or payday loan offers.
What’s Not Allowed:
- Showing search engines different content than users
- Serving crawler-only text/keywords.
What’s Allowed:
- JS/images hard for crawlers to parse (if made accessible properly)
- Paywalls where Google sees the same full content as a paying user.
Doorway Abuse
Doorway abuse involves creating low-value, repetitive pages or sites designed solely to rank for specific search queries and funnel users to a single destination. There can also be near-identical pages created to capture search traffic rather than fit a clear, browseable site navigation.
Example:
A business generates near-identical pages targeting various cities (e.g., “Renovation Services in Austin/Dallas/Houston”), swapping only the city name. Visitors clicking any result are routed or redirected to a single, generic homepage or contact form.
What’s Not Allowed:
- Duplicate near-identical sites/pages
- Region-targeted domains
- Funnel pages built to capture search traffic before the “real” page.
What’s Allowed:
- A single, clearly organized site structure where users land directly on the real, useful page for their query; no funnel pages in between.
Expired Domain Abuse
Expired domain abuse occurs when an expired domain is bought and repurposed to manipulate search rankings using low-value content, often exploiting the domain’s past authority.
Example:
An operator buys authoritative expired domains across various industries, restores minimal content, and adds contextual links pointing to a single target “money site” to fake organic, high-authority backlinks and artificially inflate its search rankings.
What’s Not Allowed:
- Buying an expired domain and repurposing it with unrelated low-value content to exploit its existing authority.
What’s Allowed:
- Buying an expired domain and building genuinely relevant, valuable content on it (topic doesn’t need to match the old site, but the content must serve users, not just exploit residual ranking signals).
Hacked Content
Hacked content is unauthorized content added to a site via security vulnerabilities. It degrades search results, harms site rankings, and can infect users with malware.
Example:
Hackers inject malicious JavaScript or hidden <iframe> tags into a website’s core source files or database. When a user visits the clean-looking website, the background script runs automatically, attempting to download malware, ransomware, or keyloggers onto the visitor’s device without their knowledge.
What’s Not Allowed:
- Malicious code
- Spammy new pages
- Hidden injected text/links
- Malicious redirects placed on a site via security exploits.
What’s Allowed:
- N/A as a “practice”. This is something to defend against, not something a site can do. Keeping software patched and monitoring for unauthorized changes is the expected standard.
Hidden Text and Link Abuse
Hidden text and link abuse hides content from visitors to manipulate search rankings. The text or link is hidden from human users solely to manipulate search rankings.
Example:
Text or links are styled to match the page’s background color exactly (e.g., white text on a white background, or #000000 text on a #000000 container). To search engine bots reading the raw HTML and CSS, the text appears fully valid, but it remains invisible to human eyes unless highlighted with a mouse cursor.
What’s Not Allowed:
- Invisible text (white-on-white, off-screen CSS, 0 opacity/font-size)
- Text hidden behind images
- Links hidden in a single character.
What’s Allowed:
- Accordions
- Tabs
- Slider
- Tooltips
- Screen-reader-only accessibility text.
Keyword Stuffing
Keyword stuffing is overloading a webpage with repetitive keywords or numbers to manipulate search rankings, resulting in an unnatural user experience. It includes dumping lists of ZIP codes or part numbers without useful context, mass-listing hundreds of city names in a dense footer block, and repetitive phrasing.
Example:
If you want the best commercial coffee maker, you need a best commercial coffee maker that brews quickly. Our best commercial coffee maker selection features top commercial coffee maker models for your business.
What’s Not Allowed:
- Unnatural lists of keywords/cities/phone numbers
- Repetitive keyword-stuffed phrasing
What’s Allowed:
- Naturally using relevant keywords/terms as part of genuinely useful, readable content
Link Spam
Link spam involves creating or acquiring links primarily to manipulate search rankings.
Example:
Excessive “link for link” agreements (“You link to me and I’ll link to you”) or complex cross-linking loops (Site A links to Site B, Site B links to Site C, Site C links to Site A) designed strictly to trick search algorithms into seeing artificial popularity.
What’s Not Allowed:
- Buying/Selling Links
- Link Exchanges
- Automated Link-Building
- Forced Links In Contracts
- Optimized Anchor Links In Paid Posts/Press Releases
- Low-Quality Directory Or Widget Links
- Footer/Template Link Spam
- Forum Signature Links
What’s Allowed:
- Paid/sponsored links tagged with rel=”nofollow” or rel=”sponsored”.
Machine-Generated Traffic
Machine-generated traffic means using automated software or scripts to visit Google Search instead of a real person.
Example:
Software tools or platforms where participants run automated browser windows in the background that continuously load and refresh target web pages. This creates artificial pageviews and inflated visitor counts to deceive advertisers or make a low-value site appear popular.
What’s Not Allowed:
- Automated queries to Google Search (e.g., rank-checking scrapers) without permission.
What’s Allowed:
- Normal human browsing and search traffic, or automated access done with Google’s express permission (e.g., via approved APIs).
Malicious Practices
Malicious practices deceive users, deliver negative experiences, or compromise user privacy and security.
Example:
A user lands on a site and attempts to leave by clicking the browser’s “Back” button. The website uses JavaScript navigation manipulation to insert dozens of dummy entries into the browser history instantly, refreshing the current spam page or redirecting to an ad network rather than exiting.
What’s Not Allowed:
- Harmful software or mobile apps designed to damage devices
- Unauthorized installations
- Unwanted Software
- Back Button Hijacking
What’s Allowed:
- Software/downloads that behave transparently and as users expect, with proper consent and disclosure.
Misleading Functionality
Misleading functionality refers to sites or tools designed to trick users into believing they can access specific features, content, or services when they actually cannot. It can lead users to ads rather than providing the services or credit claimed.
Example:
Platforms claiming to host exclusive live events, movie streams, or downloadable documents, displaying a dummy media player that forces users to register, enter credit card details, or install third-party extensions to view non-existent media.
What’s Not Allowed:
- Fake tools/generators or sites that promise a service but redirect users to ads instead.
What’s Allowed:
- Tools and services that genuinely do what they claim
Scaled Content Abuse
Mass-producing unoriginal pages to manipulate search rankings without helping users.
Example:
A home service portal automatically generates 15,000 distinct web pages by combining a base text string with a list of hyper-specific neighborhood names (e.g., “Emergency Water Heater Pipe Replacement in Downtown Sector 4 B”). The page copy remains entirely identical across all pages except for the swapped neighborhood variable, offering zero local pricing or real service presence.
What’s Not Allowed:
- Mass-producing low-value pages via AI, scraping, content-stitching, or keyword-stuffed nonsense text, including hiding this across multiple sites.
- Auto-generated pages across dozens of separate domains to mask the scale.
What’s Allowed:
- Using AI or automation as part of a process that still results in original, valuable content for users (the policy targets lack of value, not the tool used).
Scraping
Taking content from other websites and republishing it without authorization or value addition.
Example:
A developer blog deploys a background script that scans GitHub and Stack Overflow RSS feeds for newly posted code snippets. The site automatically republishes those code blocks wrapped inside auto-generated, generic explanations without crediting the original developers or adding real troubleshooting context.
What’s Not Allowed:
- Republishing or lightly modifying others’ content without adding value
- Citing sources; sites built to compile others’ media with no added value
- Embedding YouTube videos or Instagram images from other creators on a site without adding original commentary
What’s Allowed:
- Referencing, quoting, or building on other sources with proper attribution and your own added value/analysis.
Site Reputation Abuse (Parasite SEO)
Publishing third-party content on a high-authority host site primarily to leverage the host’s ranking power.
Example:
A reputable site known for reviewing computer processors and graphics cards leases a subfolder to an external marketing agency. The agency publishes dozens of sponsored, unvetted guides on “Top Unregulated Offshore Crypto Exchanges,” relying entirely on the hardware site’s domain authority to rank.
What’s Not Allowed:
- Hosting third-party content mainly to exploit your site’s existing ranking authority (e.g., unrelated sponsored content placed to “borrow” reputation, out-of-niche content, confusing category additions, white-label coupon licensing, and exploitative freelance expansion
What’s Allowed:
- Standard news syndication
- Editorial columns
- Directly managed merchant coupons, links, or disclosed native ads meant for the audience.
Sneaky Redirects
Deceptively sending visitors to a different URL than the one originally requested or shown to search engines.
Example:
A travel portal shows Googlebot and desktop users in North America an in-depth, informational guide about European vacation spots. However, when a mobile visitor from a specific target region accesses the page, the site executes a script that routes them to an online gambling app download page.
What’s Not Allowed:
- Hosting third-party content mainly to exploit your site’s existing ranking authority (e.g., unrelated sponsored content on an otherwise reputable site).
- Serving desktop users a standard article while automatically redirecting mobile users to a subscription trap.
What’s Allowed:
- Standard 301 Redirects For Domain Migrations
- Page Consolidations
- Post-Login Account Routing
- Wire/Press Release Syndication
- Forums/Comment Sections
- Editorial/Opinion Pieces
- Genuine Advertorials
- Properly Tagged Affiliate Links/Ad Units
- Merchant-Sourced Coupons.
Thin Affiliation
Publishing affiliate link pages that copy product reviews or descriptions directly from merchants without adding value. It also includes running dozens of identical template sites that reuse the exact same product listings across different domain names.
Example:
A marketer operates four separate domains with different layout skins that pull data from the exact same affiliate database. Searching for a product leads to identical price tables and affiliate links across all four sites, creating the illusion of independent options.
What’s Not Allowed:
- Copy-pasted merchant descriptions with no original value
- Templated affiliate sites replicated across domains
What’s Allowed:
- Affiliate pages with original reviews
- Testing
- Comparisons
- Unique value-add
User-Generated Spam
Spammy content submitted by unauthorized third parties through public user-input channels.
Example:
Spambots register thousands of user profiles on open technical support forums, placing target keywords (e.g., “best online casino”) into the “Company Name” or “Signature” fields while leaving zero genuine forum posts.
What’s Not Allowed:
- Uploading PDFs stuffed with casino links to public file-hosting platforms
- Spam accounts, spam forum/comment posts, and spam files on open platforms.
What’s Allowed:
- Genuine user contributions, moderated appropriately to keep spam out.
Other Practices Leading to Demotion or Removal
- Legal & Personal Information Removals:
- Copyright Demotions: Sites receiving high volumes of valid DMCA takedown requests get demoted sitewide.
- Exploitative Privacy Practices: Sites that demand payment to remove doxxing, non-consensual explicit images, or non-consensual deepfakes face heavy search suppression.
- Policy Circumvention:
- Subdomain Hopping: Creating subdomain2.example.com immediately after subdomain1.example.com gets penalized for spam.
- Scam and Fraud:
- Imposter Brand Sites: A site posing as an official airline support portal to charge fake booking change fees.
- Fake Support Phone Numbers: Pages displaying false customer service phone numbers to trick users into paying fraudulent tech support operators.
Final Words:
Google continuously updates its systems to improve user experience and prevent manipulation. Google’s web search spam policies highlight the practices that can hurt your site. If a website gets caught doing these practices, Google’s automatic AI systems can demote it, deindex the pages, or completely prevent its content from appearing in the search results.
