Search engine optimization (SEO) is the process to increase the quality and quantity of website traffic. SEO refers to the improvement of organic. SEO may target different kinds of searches, including image search, video search, news search, and industry-specific vertical searches.

Optimizing a website may involve editing its content, adding content, and modifying HTML and associated coding to both increase its relevance to specific. Promoting a site to increase the number of backlinks, or inbound links, is another SEO tactic.

As an Internet marketing strategy, SEO considers how search engines work, the computer-programmed algorithms that dictate search engine behavior, what people search for, the actual search terms or keywords typed into search engines, and which search engines are preferred by their targeted audience. SEO is performed because a website will receive more visitors from a search engine the higher the website ranks in the search engine results page.

SEO differs from local search engine optimization. In this case web pages will be displayed by search engines when a user enters a local search for its products or services. The former instead is more focused on national or international searches.
