If you’re like most people, you use Google to search for things. You may notice that if you type in the same keywords on different days, you get different results. You may chalk this up to user error, however, it’s intentional, and part of what Google calls “Personalized Results.”
Google wants each user to get what they’re looking for, and it does this by building an ever changing algorithm. What’s the algorithm you ask? In layman’s terms: it’s a set of rules that Google sets to retrieve what you’re searching for. Algorithms change constantly as new technology becomes available. According to Moz, every year Google changes their algorithms 500-600 times, wow!
