If people know they need to judge something they compare it to past knowledge and experience instead of simply experiencing it.
Instead of inviting people to participate in a focus group, make them believe they are just lucky enough to try the product first. Then watch their reactions to the product, how they use it or consume it.
As a good measurement of what was the right answer.
Allow users to donate how much they want (maybe even less than 1 dollar cent), based on their satisfaction of the result they got in the SERP. This will give a better indication as to what is a really useful answer to a specific query.
Reading is critical for your development. Wouldn’t you like to know how much you develop?
Add an OS level ability to measure text read across different applications like e-book readers, web browsers, etc., much like the steps counter already in modern smartphones.
You would like to know if your buyer does use the product you sold them and how often.
Have a “sticker” or “button” that you ask them to stick to the product they bought, and a smartphone app or the device can connect to a home wifi network directly (you can offer an incentive like a discount.) You explain to them that data is anonymized, and it will help you create better products for them in the future.
Whenever they use the product (make coffee with their new machine) or consume it (read the book to their child) they “activate” the sticker. They do so by waving their smartphone near it, or pressing a small button on the sticker), and you’ll get the data through their smartphone or directly through their home wifi.
To find out how much you write – you might want to start writing more if you see you output, maybe start the novel you’re always dreaming of.
Install software on all devices and aggregate the data online.
