Web users wise-up to Flash cookies as deletion rate rises, says. US— The reliability of Flash cookies as a proxy for measuring unique browsers is being undermined by increasing consumer awareness of the little data files and of how to delete them, according to research by Scout Analytics. The behavioural analytics firm reports a doubling in the deletion rates for Flash cookies – technically known as local shared objects (LSOs). Nine months ago, Scout said, just 3% of LSOs were deleted from the more than 600,000 devices the company tracks.
Now that figure is up to 7%. The issue with deletion is that it leads to duplicate cookies being created on an individual device, causing counts of unique browsers to be inflated. Widespread deletion of standard HTTP cookies has severely harmed their reliability when used as a form of user measurement – Scout’s own research says HTTP cookie counts overstate a website’s audience upwards of two to four times.
