I've been experiencing a steady drop in traffic since the end of March. The graph for visitors and page views in Google Analytics and my own stats program is just a downward slope.
I've compared the March through April period of 2008, 2009 and 2010 and this didn't happen in the prior two years. A decline like didn't come along until about May in 2008 and 2009 when the weather really started to warm up.
I've compared referral traffic, and the percentage of visitors from Google, Yahoo, Bing, direct traffic and other sources is roughly the same for this year as for the last two. I've also compared the traffic from search engines, and it's roughly the same.
I thought perhaps someone had hacked my site, so I uploaded all of the pages that I have locally to overwrite what's on the server.
Is there anything else I could be missing? Hacking? An obvious mistake? I've looked at the robots file and it's okay.
If you've seen a similar decline in previous years related to the arrival of warm weather, that may be it. Where I sit the weather the last couple of weeks has been much warmer than the same period the last couple of years. 2008 and 2009 both saw below normal temps for this time of year while 2010 has been well above normal.
