Search engine optimization (SEO) is the constantly ongoing process of improving your website's search engine performance and enhancing its online visibility. Its primary goal is to drive organic traffic by ensuring that the website appears higher in organic search results when users search for relevant keywords. A higher ranking on search engines such as Google and Bing can increase web traffic among potential customers actively looking for similar products or services. SEO is extremely important to all companies — from local and small to large enterprises.
SEO agencies are dedicated service providers helping businesses generate more traffic by optimizing their on-page and off-page strategies. These professionals are equipped with the best tools, knowledgeable about the best practices, and up-to-date with every change in the algorithm.
