You are looking for more information on the ever popular term “SEO”, but do not know where to start looking. Well, search no further! We at Novofex have compiled the perfect Search Engine Optimization crash course.
Today’s search engines serve two major functions – crawling websites and building an index, as well as providing the answers to searches by calculating relevancy & serving results.
What is Search Engine Optimization? Let the course begin.
Imagine the internet as a series of stations or stops along a major city’s subway station. There are many trains, and many stops, yet somehow, they are all connected.
Each stop along the route is some sort of online aspect – usually, a webpage, photo or document. Search engines need a way to “crawl” the entire city and stop along all of the stations on each train route, so they use the best path available – links within pages.
“The link structure of the internet serves to connect all of the pages together.”
Through links, search engines use “crawlers,” or “spiderbots” to reach the billions of interconnected items online.
Once the engines, such as Google find these pages, they read the key information embedded within them and store them. This information is recalled later when someone searches for such information online. To accomplish the monumental task of holding billions of pages that can be accessed within moments, search engine companies have constructed thousands of huge server-stations across the globe!
Search engines tend to act as digital answering machines. When someone searches for something, two important things occur. First, results that are relevant or useful to the searcher’s query are found, and second, ranked in order of usefulness. It is both “relevance” and “importance” that the process of SEO takes into consideration.
How Do the Search Engines Calculate a Level of Importance?
As of this date, search engines determine importance based upon the popularity of the site – the more popular a site is, then the more important the information in that page must be. So far, this assumption has proven fairly successful in practice.
A website’s popularity and relevance is not at all determined by hand. Instead, search engines create complex mathematical equations, also known as algorithms, to sort the relevant sites out in order.
These algorithms are often comprised of hundreds of components. These components are known as “ranking factors”.
