Explore SEO – Blog about Search Engine Optimization
Author: Punye Aggarwal
I love to explore how Google Search works under the hood, it's algorithms to the hardware that powers this amazing software. I write blogs and articles about Search Engine Optimization and Search Engines, especially Google. To connect with me on Social media please use my LinkedIn profile.
PageRank was the first core algorithm in Google Search and is named after Larry Page (co-founder of Google). PageRank aims at estimating the importance of a webpage on the basis of number and quality of links it receives. In short it is a link analysis algorithm.
Google always had the intuition that “speed matters” on the Internet. In June 2009 they made practical experiments and provided accurate figures demonstrating how slowing down the search results page by 100 to 400 milliseconds had a measurable impact on the number of searches per user of -0.2% to -0.6% (averaged over four or six weeks depending on the experiment).
Search is a complicated and an evolving art and science.
While there are over 200 unique signals or “clues” that Google uses to rank pages, they are actually part of very few main sections, of which the 4 most important sections are Content, Links, User Experience and On-Page Optimization.
