Whenever you enter a query in a search engine and
hit enter, you get a list of web results that contain that query term. Users
normally tend to visit websites that are at the top of this list as they
perceive those to be more relevant to the query. If you have ever wondered why
some of these websites rank better than the others then you must know that it
is because of a powerful web marketing technique called search engine optimization Brisbane.
How Search Engines Work
The first basic truth you need to know to learn search engine optimization Brisbane SEO is that search engines are not humans. While this might be obvious for everybody, the differences between how humans and search engines view web pages are not the same. Unlike humans, search engines are text-driven. Although technology advances rapidly, search engines are far from intelligent creatures that can feel the beauty of a cool design or enjoy the sounds and movement in movies; as a substitute search engines crawl the Web, looking at particular site items (mainly text) to get an idea what a site is about. This brief explanation is not the most precise because as we will see next, search engines perform several activities in order to deliver search results; crawling, indexing, processing, calculating relevancy, and retrieving.
What you can do is to check what a crawler sees from your site. As already mentioned, crawlers are not humans and they do not see images, Flash movies, JavaScript, frames, password-protected pages and directories, so if you have tons of these on your site, they should be viewable by the spider. If they are not viewable, they will not be spidered, not indexed, not processed, etc. In other words, they will be non-existent for search engines.
After a page is crawled, the next step in search engine optimization is to index its content. The indexed page is stored in a giant database, from where it can later be retrieved. Essentially, the process of indexing is identifying the words and expressions that best describe the page and assigning the page to particular keywords. When a search request comes, the search engine processes it. Since it is likely that more than one page contains the search string, the search engine starts calculating the relevancy of each of the pages in its index with the search string.
There are various algorithms to calculate relevancy. Each of these algorithms has different relative weights for common factors like keyword density, links, or Meta tags. That is why different search engines give different search results pages for the same search string. What is more, it is a known fact that all major search engines periodically change their algorithms and if you want to keep at the top, you also need to adapt your pages to the latest changes. This is one reason to devote permanent efforts to search engine optimization, if you like to be at the top.
The last step in search engine optimization is retrieving the results. Basically, it is nothing more than simply displaying them in the browser; the endless pages of search results that are sorted from the most relevant to the least relevant sites.
