Publishers and advertisers have recently felt the impact click fraud
is having in the content networks. Increasingly, publishers are seeing
a performance drop in the content network traffic quality. Advertisers
are seeing their conversion rates drop significantly on content
networks because of bad traffic coming from parked domains and other
low quality sources.
“Click fraud activity continues to grow especially on made for ad
sites, parked domains and on the content networks,” said Tom Cuthbert,
president and CEO of Click Forensics. “Advertisers, publishers and
search engines need to take notice because content networks are
becoming the fastest growing source of click fraud. Ensuring their
quality is essential for the pay per click advertising market to
continue its growth.”
