1. How often does the average user purge their cookies (Get it? Purge? Ok, bad joke...) I don't know if there is any data on this, but if there is, it would be good to know. My program has a "cookie expirey" set for one year, but I would find it hard to believe that many folks would go a whole year without deleting their cookies - especially when so many people use adaware, spybot, etc.
I'd like to have this info in my FAQ, so if anyone has any thoughts on this, your input would be greatly appreciated.
I've found some stats on how often people delete their cookies (or say they do). This comes from a study by the Atlas Institute:
Every three months:43.7
So, according to this, 100% of people delete their cookies within 3 months, and about half do within a month.
What this says to me is: If you (the merchant) set your cookie expirey date at 1 year (like mine is), it won't make any difference to the affiliates - the results will be the same as if it was set for 90 days.
What on earth would be encouraging the average neophyte web surfer to delete their cookies that frequently.
I suspect if I did a poll, I would find most people never delete their cookies, certainly not almost half every week.
You have to remember, LOTS of people use things like Adaware, Spybot and other anti-adware programs. Many anti-virus programs also include cookie killers. When you run these you have the option of dumping your cookies.
I'm not say that the poll is 100% accurate, but I imagine it's close enough so that you get the general picture. This poll was conducted by the Atlas Institute, not just some guy with a website.
Ask consumers how often they back up their hard disks, and they may come up with an average of every 20 days -- but if you check the actual interval between backups (or between the date of last backup and the failure of the hard disk), you'll find that it's 40 or 60 or 90 days instead.
Ask consumers how often they use condoms, and you might conclude that condoms are used in 85% of their sexual encounters, but if you're a condom merchant, you'd quickly discover that the actual behavior is very different (probably far below 50%).
