SEO is a search engine optimization technique. SEO represents the process of getting traffic from the “free,” “organic,” “editorial” or “natural” search results on search engines like Google, Bing, and Yahoo. Content is listed, ranked and shown based on what the search engine in question considers most relevant to users. The best way to optimize your content for search engines and rank higher is to do it organically. If you want or need fast results, you can do a PPC (Pay-per-Click) Campaign.
