Definition:
A keyword is a word or phrase (called a keyword phrase) that is used to help index content on Web pages so search engines such as Google can better categorize them and deliver those pages appropriately when people conduct searches.
In other words, Google scans your blog pages and identifies keywords and keyword phrases using a contextual algorithm. Google then indexes those pages based on the content and keywords found on those pages and delivers them when people search using the keywords found on your blog pages.
Keywords are an important element of search engine optimization (SEO).
