But what is QR code and what is it for? Well Danny Sullivan from searchengineland.com has explained it very well in his blogpost: What is a QR code and why do you need one. QR is short for Quick Response, 2D barcode, used to take a piece of information from a transitory media and put it in to your cell phone. The reason why they are more useful than a standard barcode is that they can store (and digitally present) much more data, including url links, geo coordinates, and text and they are easy to read by the modern mobile phone.
QR Code example:
What is the effect for your Website in Google’s eye? Well Google can crawl images on your site, and when it see this QR codes, Google will likely likely recognize QR codes and possibly index the content in them. And for your customer or reader, now few of the user will likely scan the QR codes with their mobile rather than type the url. It’s more convenient.
Beside that you can create your business card with this QR code in it. Which this will store your business information including your website link. Your business partner can easily read it with their mobile phone and visit your website straight away.
