Hi there

I'm sure most of you are aware of the furore following looksmart.com's
recent shift to pay-per-click (PPC).  One of the issues reported by many
people is the number of "false clicks" reported by Looksmart, i.e.
advertisers just cannot reconcile Looksmart's reported clickthroughs with
clickthroughs derived from their Web logs.  These same advertisers can
reconcile clickthroughs from other PPC providers such as Overture or Google
so the problem doesn't appear to lie with the advertiser.

I've been looking at Looksmart's robots.txt file and it is - well, shall we
say unusual?

www.looksmart.com/robots.txt

In my opinion this file demonstrates a lack of understanding of robots in
several different respects, e.g. lines like:

<snip>
User-agent: Due to a deficiency in Java it's not currently possible to set
the User-Agent.
Disallow:
</snip>

I'm wondering if this lack of understanding permeates through to Looksmart's
PPC-accounting department.

In other words, I'm wondering how many of the false clicks seen by
advertisers are from robots (particularly robots masquerading as a Mozilla
browser).  Looksmart's robots.txt does not prevent robots from reading the
URLs that cause advertisers to incur a fee.  So if Looksmart cannot
recognise the robot as a robot (and especially if they aren't even checking
for robots) advertisers could be incurring fees from robot-clickthroughs.
Most robots do not send a referrer in their HTTP request so this would
explain why advertisers could not reconcile clickthroughs.

Looksmart's URLs are featured in the SERPs (search engine results pages) of
its search engine partners, as well as throughout looksmart.com itself.  So
any robot that crawls SERPs and/or the web could cause these false
clickthroughs.  I know of at least two robots that crawl out from SERPs
masquerading as browsers to analyse why pages rank well.

So your thoughts please on

a) how many robots, given www.looksmart.com/robots.txt, would read those
looksmart.com PPC URLs?
b) how many of those robots would be recognisable as robots, i.e. use a
unique User Agent?
