This referrer has been showing up in my log files for about
a week or so, I haven't been successful finding out anything
about this.
Yesterday there was 8 occurrences, they were from different IP addresses.
Does anyone have any ideas?
Thanks,
Mike

Used, I believe, by a keyword research tool scanning sites, usually in conjunction with affiliate marketing research trying to find keywords with a CPC which relates to higher commission rates on conversion.

Nothing harmful.
