Keyword Research is identifying and analyzing specific keywords and phrases that people tend to use while searching for information, products, or services on various search engines. This research helps businesses to gauge an understanding of what their target audience is searching for and how to optimize the content and pages on their website to appear in search results when users enter those keywords.

Without proper research, businesses may end up using irrelevant or low-traffic keywords that will not bring in the right amount of traffic or revenue for the firm. On the other hand, if highly competitive keywords are targeted without adequate research, it may just be a waste of time, effort, and resources. Keyword research is therefore a crucial component of your search engine optimization (SEO) strategy. It can help you identify the most relevant, high-traffic, and low-competition keywords to target for SEO.
