Google has continually made several changes to its algorithm that powers its Search by Image feature after launching this innovative service last year. If you have not yet used this feature then you can simply go to Google images and upload or drag-and-drop a photo right into the Google Search box to get instant results. In addition, you can also use Google Chrome as well as Firefox extensions to search images from websites.
In addition to seeking out vital information simply from uploaded images or image URLs, Google has also added several other extensions to this tool with the Recursive Search by Image and Search by Drawing feature. However, Google has recently upgraded its Search by Image algorithm by improving its Best Guess feature to provide far precise guesses that displays better results than before.
Google has also incorporated its Knowledge Graph tool with Search by Image to better comprehend each search in a deeper way. Thus, in addition to images being displayed in the Search by Image results, you will additionally find information being displayed in text panels next to those images. This feature will mostly be useful when you search for specific people, places, animals, and things.
Google has also tried to display information related to those images almost on a real-time basis by extracting and displaying related news stories on those images within just a few minutes after they have been posted on the net. You can also find a lot more information and websites based on your images than before thanks to the index expansion exercise done by Google.
Google has been trying to continuously improve its services and modifying its Search by Image algorithm has enabled the company to deliver a better search experience to its users.
