Ive noticed that these horrendous gadgets for controlling your home heating and turning off your lights at night by verbal command are on the rise.

Yes I hate them, and I think the people using them are lazy. But Ive also noted that they are using these gadgets to search for things online.

Ive just read that by 2020, 50% of online searches will be voice controlled.

So what do I need to know in terms of getting my website ready ?

What search engines do the most popular voice things like Alexa use ? Do they all use Google or do they use a diversity of search engines ?

In terms of optimising my website, what will I need to do differently to cater for the customers using voice search rather than a keyboard ?
