Finding the necessary information on the internet is very critical. The massive task of scanning through all the sites and throwing up the most relevant information is a major role played by search engines. For this reason, Google makes use of complex algorithms, which carry out instructions that webmasters or those working on SEO should follow so as to get good rankings for their websites.
How it works
To understand the changing tactics of Google, it is first important to know how these steps work. When a term is entered into Google’s search engine, Google scans through the web to find pages that contain information specific to the term. The relevant pages are then arranged into an index, and then they are further analyzed and sorted out with the help of customized algorithms. The page that contains the most relevant information would be ranked first, while the subsequent pages are be ranked according to the relevancy of the information they provide.
Google’s methods simply shortens the the keyword searching process; the algorithms are expected to be accurate, quick, and effective. The higher ranked pages appear on top in the search engine results page (or SERP), meaning appropriate links appear in each search.
To get these results, search engine use a number of signals called contextual signals to rank the web pages. These include location, anchor text, title, external links, and diversity of link sources, among 200 other factors. With the help of these signals, Google is able to rank the pages and determine the most relevant results to the user.
With all these steps, the functionality of Google’s algorithms could be termed as unfathomable. The huge task of analyzing millions of pages on the web and ranking them based on the kind of information they provide, in few microseconds, is tremendous. Considering the number of queries and the frequency of queries Google receives every minute, it is unimaginable as to how the process is made to work.
Based on the changing needs and quantity of the content, the Google methods need to be updated or changed to suit the requirements arising in the market. This also helps ensure that people receive the most relevant information at their disposal just at the click of a mouse.
Timeline is one of the major aspects for search engines now and Google has always given it high priority and social networking sites have made it easier to present this information. For example, checking the scores of a live match was easier on Facebook and Twitter sometime back but, Google immediately retaliated to come up with an algorithm to beat this feature.
Google has also planned to eliminate sites with excessive SEO. Due to these changes, some companies experienced considerable drop in the rankings. What Google did was to come up with the Panda Update where the search engine has aimed at promoting high quality content. The Google Penguin Update that was released earlier this year also aimed at generating and maintaining quality content on the websites.
