It is reported that Google has been working to provide more valuable information to use instead of numerous web links.
Google has been planning to release an update to Assistant on Android that will offer more detailed and valid information to you when you ask a question.
For instance, if you are searching for a local event, Google will present you with cards containing bookmark buttons as well as associated visuals.
If you are looking for some dress or shoes, then you will be getting pictures from a website ranked high in rankings.
Similarly, if you search for something related to education/study or financial calculators you will be entertained with good content.
The searches directing towards basic web links will appear in the beautiful vertical format which suits best to your phone.
It is possible that you have already encountered the results but iOS users might have to wait for sometime to get this amazing update.
