Google head of search Amit Singhal has revealed in his Google+ post that Google has made more than 890 improvements in Google Search in past one year.
In 2009, Google told to have made 350-400 changes to search and the numbers increased to 550 in 2010. Matt Cutts in a video in 2010 said that Google makes one change per day to its core search algorithm. Amit Singhal said that the 890 improvements are search specific but also go well beyond algorithms. User interface changes, Google Now, auto-complete, and many more enhancements are a part of the number.
Looking back at the 10 year anniversary of Google IPO, Amit also shared his "10 biggest Google search milestones since 2004". Here's the list:
1. Autocomplete: We built a way for Google to predict the most likely useful words and phrases as you type, and even load search results instantly – so you can quickly get to that perfect recipe for a “silky gingered zucchini soup” (even if you can’t remember the dish’s whole name). Typing out a whole phrase feels archaic.
2. Translations: Google Translate was barely a beta product ten years ago. Today people use it in 80 languages to do over a billion translations a day. Just tell Google to “translate 10 years into German” and see this magic in action.
3. Directions and traffic: Search used to be just about webpages, but our amazing Maps team made it possible to search the real world too. Now you can ask, “How far is it to Santa Cruz” and with one tap you can open walking, biking, public transit, or driving directions – with the fastest route so you avoid traffic.
4. Universal search: Sometimes the best answer isn’t just text – if you are asking about JFK’s “Moon Speech,” probably want to watch John F. Kennedy deliver his famous speech. We have made that possible, blending different types of results so you get the most relevant info, no matter the format.
5. 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 have 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!
6. Voice search: Gone are the days of typing queries as clunky keywords – you can now ask questions by voice in the Google Search app. Instead of typing [weather chicago], just say “Ok Google, will I need an umbrella tomorrow?” We’ve invested years of research into speech recognition and natural language understanding, and voice search works in 38 languages today.
7. 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 â€œRemind me to pick up coffee filters next time I’m at Target,” and Google will buzz your phone when you get to any Target.
8. The Knowledge Graph: The world is made of real things, not just text strings. So we built the Knowledge Graph to show how things are connected- ask “How tall do you have to be to ride the Cyclone?” or “Who’s in the cast of Guardians of the Galaxy?”, and then click to explore across the web.
9. Info just for you: If you’ve got a flight reservation saved in your Gmail, you can ask the Google Search app,- “What gate does my flight leave from?”, and get the answer directly. You can also ask about shipments ("Where's my package?") or for appointments (“When do I have yoga?”). All this is private of course, visible just to you.
10. 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.Google Made more than 890 Improvements to Search Over the Past Year!,
