HOW PINTEREST HACKED GOOGLE IMAGES

Summary from the TLDR Marketing newsletter

Pinterest captured massive traffic from Google Images by turning UGC into an SEO engine. Search crawlers read text rather than images. Pinterest structured board titles, pin descriptions, and comments into indexable pages, then built templated pin, board, and programmatic explore pages designed to match high volume queries. Each user action created a new searchable entry point, forming a self-reinforcing growth loop that drove hundreds of millions of organic visits. A login wall gated full content behind registration, converting search traffic at scale until Google's 2018 algorithm update penalized the tactic and erased millions of rankings.
