I’ve been using the same hosting service since 2009 and just went back and collected yearly stats for “unique visitors”.
The data for 2009 was only for 11 months so I multiplied by 12/11. The data for 2015 is for 5 months so I multiplied by 12/5.
The overall trend is for a general increase in activity, but this year could be slightly down over the past couple. However one real popular blog posting could affect the yearly results in a big way. November of 2014 had a major temporary increase in hits with my report of Steve Wozniak still thinking about improving the Apple II design generating over 26,000 visits for that month alone.
The total number of “unique visitors” over the last 6+ years is 537,704.
