The so-called "Search Engine Result Pages" (SERPs for short) are those pages of a search engine that appear when a user enters a search query.
The results are displayed in descending order of relevance and vary depending on the search engine. The position of websites depends on many different ranking factors, which are not openly communicated by the respective search engines. To avoid spam or manipulation.
The results of the search within the SERPs are displayed in the form of snippets or rich snippets. Depending on the search query, Google displays up to ten snippets, some of which are supplemented by ads, images or social media tweets.
SERPs are of great importance for search engine optimization (SEO), since a better placement compared to competitors generates more visibility and thus more traffic, which in turn leads to more leads and ultimately to higher profits.
