While Google search may appear to some as a somewhat static service that remains generally the same year after year, the company is constantly adding updates in order to stay on top of the competition. In a recent Google+ post, the company's head of search, Amit Singhal, says Google has made more than "890 improvements" to its search engine in the last year alone.
To others, these kinds of updates are expected, but the number has risen significantly over past years. In 2009 Google said it made nearly 400 changes to its search engine and as many as 500 the following year. It is widely known that Google tests out hundreds of updates and changes everyday, but very few of them actually get implemented. In the past, the company said it makes one change every single day to its core search engine.
The 890 changes Singhal is referring to are more than just core algorithm updates though. There are changes on everything from the user interface to Google Now and many other things.
Included in his Google+ post, the head of Google search also shared some of his fondest and most memorable milestones in Google search history including adding things like directions, voice search and the introduction of predictive features like Autocomplete. You'll find the complete list on Google+ and a few others Singhal pointed out below:
Universal search: Sometimes the best answer isn't just text---if you're asking about JFK's "Moon Speech," you probably want to watch John F. Kennedy deliver his famous speech. We've made that possible, blending different types of results so you get the most relevant info, no matter the format.
Mobile and new screens: No matter what device or platform you may be on, whether it's a tablet or a smartphone (or even a watch!), you need information and answers. So we've adapted Search to all these new devices. This includes redesigning our mobile products to help those who weren't born with the fastest typing thumbs!
Actions: With the Google Search app you can quickly text, email or call someone without digging and typing. Just say: "Ok Google, send an email to Jason: do you guys want to go to the beach with us for a picnic this Saturday?" You can even set sophisticated reminders like "Remind me to pick up coffee filters next time I'm at Target," and Google will buzz your phone when you get to any Target.
Answers before you have to ask: If you have the Google Search app on your phone, you'll get automatic help with everyday tasks. Google can automatically show you your plane, bus, and train reservations right when you need them; warnings when traffic is bad to your next appointment; reminders of bills coming due; a best guess at the last spot you parked; and much more.
