SERP stands for Search Engine Results Page — the page a search engine displays in response to a user's query. Modern SERPs contain far more than blue links: paid search ads at the top and bottom, featured snippets (direct answer boxes), People Also Ask accordions, local map packs, image carousels, video results, shopping panels, and Knowledge Graph cards.
SERP scraping is used for keyword rank tracking (monitoring where your site or a competitor's site ranks for target queries), competitive intelligence (tracking which ads competitors are running, what messaging they use), market research (understanding what content ranks for a topic), and ad intelligence (monitoring ad creatives, landing pages, and bidding strategies).
Search engines actively restrict automated SERP access because their query results represent their core business asset. They deploy CAPTCHA challenges, IP reputation systems, and JavaScript-based bot detection specifically for scraping prevention. AlterLab's SERP endpoint handles these protections transparently — submit a query string and receive structured SERP data including organic results, ads, and rich features.
