I've been using Infolinks, serving in-text advertising links, for 12 months now and it looks like the honeymoon is now well and truly over. Initially the eCPM I was seeing from Infolinks was solid, and well above anything I'd been getting with Kontera.

As you can see in the graph below, my first full month with Infolinks was pretty good, bringing me a respectable $3+ eCPM. Following the first month, things levelled off, to the point where I was averaging between $1 and $1.50 eCPM for several months.

Things began to unravel during September 2009, when my eCPM dropped below $1 for the second month in a row. The downward spiral has continued since, with my Infolinks eCPM hovering around the $0.50 mark. To put this into some perspective, it means that my Infolinks earnings have dropped by a half to two thirds. I plan on sticking with them for a little longer in the hope that this downward trend turns around, but my patience will only last so long.

For anyone else out there that uses Infolinks, what has been your experience? Have you noticed a similar trend?
