Search engine optimization
open-in-new
<p>Search engine optimization (SEO) is the process of improving the quality and quantity of <a href="/facts/Web_traffic/vmR1QQDP">website traffic</a> to a <a href="/facts/Website/SAsjJnca">website</a> or a <a href="/facts/Web_page/5JK7xQLe">web page</a> from <a href="/facts/Web_search_engine/SRntsbz2">search engines</a>. SEO targets unpaid search traffic (usually referred to as "<a href="/facts/Organic_search/zkpKY3v0">organic</a>" results) rather than direct traffic, referral traffic, <a href="/facts/Social_media/kUIkfpIA">social media</a> traffic, or <a href="/facts/Online_advertising/Ncsv0GRz">paid traffic</a>. </p><p>Unpaid search engine traffic may originate from a variety of kinds of searches, including <a href="/facts/Image_search/pkcq1rTk">image search</a>, <a href="/facts/Video_search/bmvtYYg2">video search</a>, <a href="/facts/Academic_databases_and_search_engines/lwtFTh9l">academic search</a>, news search, and industry-specific <a href="/facts/Vertical_search/Qz6w7sFR">vertical search</a> engines. </p><p>As an <a href="/facts/Internet_marketing/l7EzpU8p">Internet marketing</a> strategy, SEO considers how search engines work, the computer-programmed <a href="/facts/Algorithm/fnl5NmRt">algorithms</a> that dictate search engine results, what people search for, the actual search queries or <a href="/facts/Keyword_research/cSrs31xM">keywords</a> typed into search engines, and which search engines are preferred by a target audience. SEO is performed because a website will receive more visitors from a search engine when websites rank higher within a <a href="/facts/Search_engine_results_page/tpmnjUDa">search engine results page</a> (SERP), with the aim of either converting the visitors or building brand awareness. </p>
