Search engine optimization is the science of improving a website to increase its visibility when people search for products or services.
The more visibility a website has on search engines, the more likely it is that brand captures business.
In Google and other search engines, the results page often features paid ads at the top of the page, followed by the regular results or what search marketers call the “organic search results”. Traffic that comes via SEO is often referred to as “organic search traffic” to differentiate it from traffic that comes through paid search. Paid search is often referred to as search engine marketing (SEM) or pay-per-click (PPC).
HOW SEO WORKS :
Search engines such as Google use an algorithm or set of rules to determine what pages to show for any given query. These algorithms have evolved to be extremely complex, and take into account hundreds or even thousands of different ranking factors to determine the rankings of their SERPs. However, there are three core metrics that search engines evaluate to determine the quality of a site and how it should rank:
Links – Links from other websites play a key role in determining the ranking of a site in Google and other search engines. The reason being, a link can be seen as a vote of quality from other websites, since website owners are unlikely to link to other sites that are of poor quality. Sites that acquire links from many other sites gain authority (called “PageRank” in Google) in the eyes of search engines, especially if the sites that are linking to them are themselves authoritative.
Content – In addition to looking at links, search engines also analyze the content of a webpage to determine if it would be relevant for any given search query. A large part of SEO is in creating content that is targeted towards the keywords that search engines’ users are searching for.
Page structure – The third core component of SEO is page structure. Because webpages are written in HTML, how the HTML code is structured can impact a search engine’s ability to evaluate a page. Including relevant keywords in the title, URL, and headers of the page and making sure that a site is crawlable are actions that site owners can take to improve the SEO of their site.
THE BENEFITS OF SEO
Search engine optimization is a key part of online marketing because search is one of the primary ways that users navigate the web.
Search results are presented in an ordered list, and the higher up on that list a site can get, the more traffic the site will tend to receive. For example, for a typical search query, the number one result will receive 40-60% of the total traffic for that query, with the number two and three results receiving significantly less traffic. Only 2-3% of searchers click beyond the first page of search results. Thus, even a small improvement in search engine rankings can result in a website receiving more traffic and potentially business.
Because of this, many businesses and website owners will try to manipulate the search results so that their site shows up higher on the search results page (SERP) than their competitors. This is where SEO comes in.
