E-commerce is, well, can be, known as a cut-throat business. You must arm yourself with all the proper knowledge and the tools to make your site better than the rest. Every day, more and more websites are climbing onto the bandwagon to optimize their websites to climb up the rankings. If you drop your guard, you may well be trampled on and left in the void filled with so many failed e-commerce sites.
SEO, or Search Engine Optimization, has 2 major functions; draw crawlers from search engine connections and build an index of the data it collects. Moz.com uses a great analogy in their Beginners Guide to SEO - think of the world-wide web as a network of stops in a big city subway system. It’s a means for the search engines to navigate the entire network while finding and cataloguing all the content on the way. I like to call them crawlers. (Plus, doesn’t thinking of them as little data-hungry critters make it more fun?)
Links are what allow the crawlers to meander their way around. Once found, they absorb the details and store the most relevant information into a database. Search Engines are the means to access the networks of data caches these crawlers have pulled together. What does this mean to you? The better a crawler can see and access your web information, and the more relevant it is (plus a few other factors) means better search result placement.
