Internet is galaxy of information; we can access the desired information in fraction of seconds. But, preparation of accumulating and sourcing the accurate information to user is not so simple. There are approx 150 million active Web sites over Internet with varied information and the task of shifting through all those sites to find helpful information is monumental. That’s why search engines use complex algorithms i.e. mathematical instructions that tell computers how to complete the assigned tasks.
Google as search engine –
Use algorithm to explore Web pages that contain the keywords used to search on Google, and
Assign a rank to each page based on several factors e.g. number of times the keywords appear on the page.
After filtering & shorting as mentioned above, higher ranked pages appear further up in Google’s search engine results page (SERP), meaning that the best links relating to your search query are theoretically the first ones in Google lists.
Every year, Google changes its search algorithm around 500–600 times. While most of these changes are minor, Google occasionally rolls out a “major” algorithmic update (such as Google Panda and Google Penguin) that affects search results in significant ways.
For search marketers, knowing the dates of these Google updates can help explain changes in rankings and organic website traffic and ultimately improve search engine optimization (SEO).
Below, we’ve listed the major algorithmic changes that took place in the year 2016 and have had the biggest impact on search.
Google’s PageRank System
PageRank is an algorithm used by Google Search to rank websites in their search engine results. It was named after Larry Page, one of the founders of Google and it is a way of measuring the importance of website pages.
PageRank system arguably is the most important feature of Google algorithm. It is an original automated process that determines where each search result appears on Google’s search engine result page. Most users tend to focus on the first few search results, so getting a spot at the top of the list usually means more user traffic. So how does Google determine search results standings? Many people have taken a stab at figuring out the exact formula, but Google keeps the official algorithm a secret.
So now it is important to know that:
- PageRank assigns a rank or score to every search result. The higher the page’s score, the further up the search results list it will appear.
- Scores are partially determined by the number of other Web pages that link to the target page. Each link is counted as a vote for the target. The logic behind this is that pages with high quality content will be linked to more often than mediocre pages.
- Not all votes are equal. Votes from a high-ranking Web page count more than votes from low-ranking sites. You can’t really boost one Web page’s rank by making a bunch of empty Web sites linking back to the target page.
- The more links a Web page sends out, the more diluted its voting power becomes. In other words, if a high-ranking page links to hundreds of other pages, each individual vote won’t count as much as it would if the page only linked to a few sites.
- Other factors that might affect scoring include that how long the site has been around, the strength of the domain name, how and where the keywords appear on the site and the age of the links going to and from the site. Google tends to place more value on sites that have been around for a while.
- Some people claim that Google uses a group of human testers to evaluate search returns, manually sorting through results to hand pick the best links. Google denies this and says that while it does employ a network of people to test updated search formulas, it doesn’t rely on human beings to sort and rank search results.
Google’s strategy works well. By focusing on the links going to and from a Web page, the search engine can organize results in a useful way. While there are a few tricks webmasters can use to improve Google standings, the best way to get a top spot is to consistently provide top quality content, which gives other people the incentive to link back to their pages.
