SEO is essentially a constantly evolving study of what factors the search engines take into account when they ‘rank’ you in their natural search listings. ‘Natural’ search listings are the main lists of results that come up when you search for something. They’re in addition to the PPC lists. The PPC (paid) entries tend to feature at the top and right side of the page. All the others are ‘naturally’ listed from the Search Engine’s index. Search Engines use algorithms to determine a website’s relevancy and importance. This is how they decide on which order to place them in.
When you begin and SEO campaign, start by focusing on your on-page optimization. The practice of on-page optimization is all about what you do on your web page to help search engines understand your content and what your site is focused on. Even though off-page optimization is an important factor in the rankings equation, on page optimization builds a strong foundation for all SEO efforts.
