Keyword research’ is a practice used by search engine optimization professionals to find and research actual search terms people enter into the search engines when conducting a search. Search engine optimization professionals research keywords in order to achieve better rankings in search engines. Once a niche keyword is found, it is expanded upon to find similar keywords. The process is usually aided by keyword suggestion tools, which offer thesaurus and alternate keyword suggestion functionality. Most of the time the various search engines provide their own keyword suggestion tools as well which also include the number of searches made for each of those keywords. This information is then used in order to select the correct keyword depending on the SEO goals of the website.
The objective of keyword research is to generate, with good precision and recall, large number of terms that are highly relevant yet non obvious to the given input keyword. Process of keyword research involves brainstorming and the use of keyword research tools. In order to achieve best results with SEO, it is important to pick the most relevant keywords. It is a good practice to pick keywords that have little competition and high amount of searches. Little competition will make it easier to achieve higher rank in search engines and high amount of searches will guarantee that the keyword attracts web traffic. The downside of this practice is that usually keywords that have very little competition get less searches while those who get millions of searches per month are very difficult to rank for.

Good keywords are related to the theme of the website. search engine algorithm has the right to ban or exclude from search results websites whose content is not relevant to the keyword. Good Keyword that are highly competitive are less likely to rank in the top. Keywords that have no monthly searches will not generate any traffic therefore rendered useless for SEO.
