Ways to Identify and Tackle Click FraudIdentifying
and tracking examples of click fraud is the first step to eradicating the
problem. Click fraud is an enormous
drain on the resources of advertisers operating on a national and international
scale, estimated to occupy around 30% of all pay per click advertising
spend. With so much at stake, its
no wonder the search engines are investing so much time and effort into
devising solutions. One
way in which Search Engines and other pay per click programme providers have
attempted to curb the growing click fraud problem is through introducing IP
address repetition algorithms.
These formulae are designed to pick up on suspicious click patterns
emanating from a singular IP address, which can help to uncover the existence
of click farms and competitor-led sabotage, as well as identifying potential
fraudsters at source. However,
there is an array of problems with this method of attempting to identify the
fraudsters. Firstly, fraudsters
logging on through a dialup modem, DSL line or cable modem can almost
completely bypass this check, as with every new online session, a new IP
address is generated. Furthermore,
there is an extensive range of software available to alter IP addresses, which
again can be used for 'cheating' the algorithm. Cookie and session tracking are other
methods by which search engines can attempt to uncover potential fraudulent
activity, but again there are ways around these for the fraudsters. More
comprehensive software is being developed which profiles and reports on the
browsing habits of each click-through to enable companies to track and monitor
suspicious behavior, although this could be seen by many as intrusive and
ineffective as anything on a small scale is still likely to go unnoticed, based
on the vast coverage of ads across the internet. The
problem of click fraud recently hit the headlines with a class action raised
against Google, prompting Google to offer $90million as a potential
settlement. Perhaps an acceptance
of their responsibilities, Google's offer goes some way to suggest the extent
of click fraud, and its vast costs to the internet economy.
