Keywords are the words or phrases that pop up frequently on a web page, article, or blog post. These are the keywords that are typed in by the person searching for some specific information. The web pages, articles, and blog posts that contain the specific keyword(s) or keyword phrases appear in the search results. But getting your website or blog to rank higher for specific keywords is the real challenge that's faced by many business owners and marketers.
While Google has historically kept marketers and SEO experts on their toes by regularly releasing updates to its search algorithm, the one thing that has remained consistent in its importance is: keyword research.
