Wikipedia defines SEO—Search Engine Optimization—as
You use SEO practices in order to create a website that will be found by search engines and visible in search results without paying for advertising on Google, Yahoo or other search engines. There are both technical/invisible and creative/front-end methods that will improve your visibility to search engines and ranking in search results, though both require discipline in your website updates.

There are around 250 million registered domains on the web, and around 1 billion websites. It is important to create a site that will stand out to search bots and to search engine users if you hope to grow your business online.
Google is used for 80% or more of internet searches, making it one of the most powerful players in the search engine optimization game. Keeping up with Google’s updates to their search algorithms is important to your SEO strategy, and most other search engines will eventually adopt similar changes to their algorithms as well. Last year, Google announced that they had begun factoring in a website’s mobile-friendliness to its search rank. In May 2016, they are expected to make further updates to their algorithm that will favor websites with responsive and mobile friendly designs over those that can only be viewed on large screens.
A website with a technically-perfect architecture optimized for search engines will only take you so far—much of search engines’ rankings also depends on the “popularity” of the website as well. Google, Yahoo and other engines have multiple factors that determine a site’s popularity. Exact formulas are unknown, but key elements of any SEO strategy include keeping abreast of published updates from the major search engines, regular website updates and relevant content.
