The page that a search engine returns after a user submits a search query. In addition to organic search results, search engine results pages (SERPs) usually include paid search and pay-per-click (PPC) ads. Thanks to search engine optimization (SEO), ranking position on a SERP can be highly competitive since users are more likely to click on results at the top of the page. With the launch of schema markup, SERPs are becoming much more complex to try to anticipate user needs.
