Contextual advertising involves the creation of an advertising campaign that would be based on a distinctive word for the theme of a particular website. At the same time, it should be a keyword that is frequently searched for by internet users. The selection of keywords is very important for web positioning, because if a word is chosen that no one searches for, all the effort put in will not have positive results on the visibility of the website on the web. The keyword should be in many places on the page e.g. title, content and headings.
