Search engine optimization (SEO) is the process of increasing the quality and quantity of website traffic by increasing the visibility of a website or a web page to users of a web search engine. The presence of your website on the first page of Google is essential. The most beautiful storefront or the best on-line shop is worthless if nobody knows it exists. Optimizing your web promotion makes your website visible to internet users. A successful web promotion strategy is the assurance of qualified traffic for your site. You hit your target audience directly and thus increase your conversion rate and your turnover.
