So this may seem a little off track now – but I think it will make sense after next week’s Byte. Until then you’ll just have to look at this as knowledge for knowledge’s sake.
What’s a QR Code?
Here’s the definition from Wikipedia: A QR Code is a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave in 1994. The “QR” is derived from “Quick Response”, as the creator intended the code to allow its contents to be decoded at high speed. http://en.wikipedia.org/wiki/QR_Code
Originally I think it was primarily used for tracking and inventory but the use has expanded and the popularity is growing as mobile tagging becomes bigger.
What’s mobile tagging?
Again from Wikipedia: Mobile tagging is the process of providing data on mobile devices, commonly through the use of data (such as a URL) encoded in a two-dimensional barcode, meant to be read and inputted using a camera phone. http://en.wikipedia.org/wiki/Mobile_tagging
So if I produced a movie, I might create a poster that included a QR code in the corner so if someone liked the poster then could point their mobile phone at the code to see a clip of the movie online.
Kinda cool. Huh?
So here’s my funny web site of the week for you: http://www.findagrave.com/
I learned about it on a bus ride across Scotland last week. The bus driver must have mentioned it half a dozen times.
Thanks to my friend Sheldon in Minneapolis for the heads up on Google’s latest SEO criteria. I’ve been touting for years that three things matter in terms of Google Ranking:
Good use of relevant keywords (to the searcher as related to your site)
Good links into your site
Freshness of content
Well it looks like I can add fast download to my list:
How do they test speed? Well by the Googlebot (Google’s spider that tracks your site and others) and the Google Toolbar. Rumor has it that this has had an impact on few sites. I don’t have a specific download speed – but I think it’s like porn, we know it when we see it.
So my advice for the week – keep an eye on how fast your web page loads.
