Finding the information you are looking for on the internet is a Herculean task. Nearly 150 million websites are active on the world wide web. This means you will have a really hard time sifting through the internet to find one important topic of your interest. Many search engines are equipped with formulas and algorithms to make the task of searching easy. Algorithms are mathematical instructions that tell the computer what to do for an assigned task. For example, Google algorithm searches for webpages that contain the keywords and phrases that you have entered. However, not all websites get displayed in one line when you perform this search. Instead, the algorithm meticulously calculates the input data and assigns a rank to each page of prominence. The ranking depends on several factors that will be discussed later. The important thing here is to note that higher ranked pages appear further up in the results page. This means you are about to see the best link related to your search query first and the rest below. For many businesses and organizations, being listed on the top of the search engine results will be a big boost in terms of visibility and site traffic. With flowing traffic, a business can increase its sales and profit easily. A search engine’s keyword search is done with the help of algorithms written by web programmers.
These are aided by automated programs such as crawlers and spiders that travel the web, from one link to another building up an index page that includes keywords and relevant information. The search engine references this index when the user is searching for something. The search engine algorithm then lists the pages that contain these keywords. Note that programs like spider and crawler are capable of differentiating between real websites and webpages that contain redirected links to the actual website. The results you will obtain are the ones that are fetched carefully through these programs. Placement of keywords plays a huge role in how a search engine finds the relevant websites. The search engine looks for the entered terms throughout the page and determines the importance of some sections over others.
The search engine also looks for the keywords in titles and headings. Headings that are in larger sizes are given more importance than smaller sized headings. The best tip while editing a webpage is, therefore, to disperse the keywords as much as possible for the best results. Overusing keywords may fetch mediocre results. Creating a search engine algorithm which scales to today’s extensive use of the web comes with many challenges as well. The crawling technology needs to be faster than ever to keep up with the growing number of internet users. This technology has to gather useful information and keep them up to date. Storage spaces must be used as efficiently as possible in order to store indices and documents. The indexing system must process hundreds of gigabytes of data at the same time. All search engines have one thing in common. The most important feature of most search engines that are found in today’s internet world is the Pagerank System, which is an automated process that determines the location of each search engine result. As you know, users who have entered keywords tend to look their answers in the first few search result lines. But how does the search engine determine where a website needs to go.
Some search engines such as Google are secretive about their algorithm technique. Others implement more straight-forward and less time-consuming formulas. PageRank System in a typical search engine assigns a rank to every search result. If the score of a webpage is higher than the rest of the pages, that result will appear first. The score or the rank for a website or a webpage is again determined by the number of links that the page is associated with. The logic behind this concept is that webpages that are linked to other similar pages have high quality content than the rest. This does not mean that the algorithm blindly selects a webpage that has the highest number of backlinks. In other words, the voting is not solely dependent on the number of websites that the targeted website is linking to. For example, if a high-ranking website links to hundreds of pages, each individual vote doesn’t count as much as it would if the webpage was linked
to only a few sites. There are other factors that determine the highest voted website that are briefly noted below. The factors that affect score or rank of a website include how long the site has been on the internet as well as the strength of the domain name. The positioning of the keywords also plays an important role in determining the rank. Also, the age of the backlinks on the website will also be considered when the algorithm calculates the score. Search engine websites such as Google gives more importance to websites that are old or have been around for a while. Some of the information that are available on the internet point out that certain companies that own search engines use manual testing method to evaluate the ranking of a website. This is not true. The fact is, manually testing is cumbersome and inefficient compared to algorithms for search engines.
Hiring a network of people for doing the tasks that need constant updates is not a smart thing to do either. Many companies have denied such claims and we now know the reasons why manual approaches don’t work. Search engine algorithms, moreover, are in a better position to focus on the links that are going to and from the targeted webpage as well. This way it is able to organize the results and give them back to the user. Note that the best way to improve search engine standing, in this scenario, is to provide high quality content consistently. This gives other website owners the reason and incentive to link back to their pages.
