For those tech-heads out there, the new book Click - What Millions of People Are Doing Online and Why It Matters is an interesting read.
The author, Bill Tancer, has been writing about how people use the Internet, and especially search engines, for years.
Overall, a complex and fascinating read, I think there is one nugget I can definitely give out as advice - if you do anything regarding diets, stopping smoking, or other habit changes, you should absolutely binge on pay-per-click advertising from December 30th-January 4th. The bulk of New Year's resolution searching is made at that time. By the time the 5th has rolled around, search volume on New Year's resolution items drops down to pre-holiday levels.
This should stand out especially for hypnotherapists and coaches.
