Content and Keywords for Optimal SERP Rankings
Keywords are specifically considered terms and phrases that can be incorporated into both the substance of a web page's content and some of the labeled tags set up behind the scenes for the purposes of search engines' indexing processes. On top of helping the crawlers identify which particular queries a given page should be included in SERPs for, keywords are critically important for distinguishing one's brand as something that is not overly redundant with an established competitor. A great deal of expense is routinely made by site owners to work out "quality" keywords that potential consumers are likely to input as search queries without finding anything currently listed in the resulting SERPs that serves their exact interests.
Those recently introduced to SEO may be forgiven for assuming that there is a simple correlation between the highest-quality keywords and the highest rankings on the relevant SERPs. However, someone searching for a particular term would most likely be doing so with a certain context in mind, one that is commonly understood to be implied by the usage of the key phrase to begin with. This context often shapes users' expectations of the type of content that websites dealing in the subject matter of their query put forth.
In a broad example, if a query is the name of an obscure species of animal, users who would input that string would expect color photographs taken in the style of a nature documentary. If one's own nature-focused website has a page about that species, therefore, it must include similar photographs to match the "standards" set by its competition. Otherwise, a page merely describing that animal through text will most likely get much less traffic from a user base primarily intent on seeing pictures of it.
Therefore, when a website's owner researches the perfect keyword for their site, they should run that keyword through Google's search service and see whether the most popular results predominantly present their content as short paragraphs, long-form articles, slideshows, and whatnot. Matching that style of content will increase the likelihood that the site will fulfill its users' search intent.
