Search Engines - How they work
I created this blog to mainly inform those new to online Entrepreneurship about the basics of online business as well as inform my readers about the new stuff I learn each day by engaging in Internet business activities. Writing and selling e-books about how to become super duper rich is not my goal here, plus I do not consider myself a guru or any other supernatural being.
So let’s start from the very beginning. What do you need to know about Internet, search engines, website marketing, etc, etc, to be a success online?
Search Engine is a program designed to search documents, images, information and other forms of files. The search is based on specific keywords and then returns a series of directory where the given keywords are located. This is done by sending out a spider to get as many files and documents as possible that pertains to the area or topic being searched, thus, enabling users to search for specific documents on the World Wide Web. Without the sophisticated search engines it is virtually impossible to navigate and find documents and data that are on the Internet unless you know the specific URL of the document that you are looking for.
Technically there are three types of search engines: Those that are derived and powered by human submissions; then those which are derived and powered by robots often times they are called spiders, bots, spiderbots, crawlers, or ants; then the hybrid type this are the combination of the two search engines. The spider based search engine uses automated software agents that visit a website, and then read it’s content; it may read the site’s Meta tags, title tags and also follows onsite links, thus performing automated indexing on all the other web resources that are linked to the site. The spider or crawler in turn returns all the gathered information back to central depository of the system where all the data are properly indexed. The spider visits the site periodically to check for any additional information or updates that the website may incorporate. The frequency at which these visits occur depend on a number of factors, and one of the most important ones is the number of other websites that link back to yours.
On the other hand the human powered search engine depends upon human intervention to submit any information after it is properly indexed and catalogued. Only the information that is manually submitted is added to the index.
In both cases, when you perform a search you are actually browsing through the index that was created at some point and is updated daily and not actually “searching the web”. This is a giant database of all information that the search engine has collected, stored and searched in the process. The two biggest search engines in the world today are Yahoo and Google (however in my opinion very soon it will be Google only, and the rest will just die out).
Search algorithm plays an important role in determining the significance of websites content. The algorithm scans sites for the frequency and specific location of keywords on a web page. Those with higher frequency may be more relevant. Another thing the algorithm does is it checks how the pages are linked to other sites on the web. By analyzing the sites that are linked to one another (such parameters as relevance, keyword placement) search engines can determine whether the indexed pages deserve to be given a boost in ranking.
