Cloaking
Showing search engines different content than users see — a guideline violation risking deindexing.
What is Cloaking?
Cloaking is the practice of presenting different content or URLs to search engine crawlers than to human visitors — typically to achieve rankings for keyword-optimized content while directing users to affiliate offers or landing pages that would not rank independently.
Cloaking In Practice
Cloaking is explicitly prohibited by Google's webmaster guidelines and can result in complete domain deindexing via manual action. Modern crawlers render JavaScript and rotate user agents to detect it — what worked in 2010 is reliably detectable in 2026. Cloaking should not be confused with link cloaking — the legitimate practice of masking affiliate URL parameters for cleaner presentation. Link cloaking redirects users through a shorter URL to the same destination; SEO cloaking shows crawlers fundamentally different content than users receive. The distinction is meaningful: link cloaking is standard affiliate practice; SEO cloaking is a spam policy violation.
Example of Cloaking
An affiliate creates a page with 2,000 words of keyword-optimized review content. When Googlebot crawls the page, it sees the full review. When a human visitor loads it, JavaScript detects the browser and redirects them to the merchant's signup page with an affiliate link — bypassing the review entirely. Google's crawlers detect the discrepancy through rendering, issue a site-wide manual action, and the domain loses all rankings. Recovery takes six to eighteen months.
