Something got my attention today, as I was analyzing traffic to my blog. Looking in Google Analytics I see 4 visits from a Flickr photo I posted a while ago, that has a link to my blog in the description:
Stats for referrer in Google Analytics
But when I look on the Flickr stats page for the photo – I see no hits for the period:
Photo stats shown on Flickr
Now I know that Google analytics may not be reliable,but clearly Flickr is even worse. AFAIK, he only way those hits would not be registered would be if I would go to that photo while logged in. And I assure you I did not do that…
So, just based on this simple analysis, it looks like Flickr stats are wrong, and probably on the low side.
