RE: "What date did you experience the loss in traffic? How big was the drop? .....?"
First, I am a small operator selling my project management software from my site. I used to get perhaps 1000 visitors a day, largely due to one organic search term "project management software". About 10% of visitors would download a trial copy of my program.
Actually I just checked and it was early-2008 when I turned on Analytics. Visitors dropped maybe 20% therafter and didn't bounce back. Traffic has steadily gone down since, with major drops somewhere about 1-2 years ago (penguin? panda?)
I had made improvements to the site (added relevant content, fixed HTML, etc,) on and off since that time but it didn't help. I took the analytics html code off my website after a year of declining results. Things continued to decline.
Visitors have dropped to 100 per day and that's probably including the various bots that visit.
As of last summer I was still showing up on the 3rd page SERPs for that search term. Then somewhere around October I dropped to page 5, and then in December to anywhere from page 15-20.
Recently I tried re-installing the analytics html code on the site. Now, I don't show up at all that I can find.
I admit I'm a small time operator and do my own web design. In the past it was relatively successful but now its not. Once I did employ an "SEO Professional" to work on my site but the resultant changes were trivial and there was no improvement.
I am sure there are many other factors at work here. For one thing out of 300+ actual backlinks google was acknowledging about 40. Now the links are still there but google acknowledges less that 10. (I'm using the Google Toolbar to see that),
I've come to this site in search of knowlege and am crawling the various articles. But I've always wondered about the coincidence of analytics.
Sorry for all the details....
