Search engine marketing (SEM) is one of the most important types of online marketing. It can be divided into search engine advertising (SEA). Here, advertisers pay for their own website to be listed above other websites. This paid advertising is displayed, for example, on Google in special areas on the search results page (SERP – Search Engine Result Page) and marked as such. Another method is search engine optimization (SEO or Search Engine Optimization). Here, one is trying to get one’s own Internet presence displayed as high up as possible in the organic search results.

A statistical model makes predictions about input data based on learned patterns. Language models, for example, predict the next word in an input sentence. A model has an architecture and must be trained to build the statistical model.
