Last week, we released RKG Duck, a Windows Clipboard Filter. I described some simple uses in an introductory video demo. I wanted to make a second video to show how write your own filters.
With George’s post on the limitations of AdGroups still fresh on the blog, (AdGroups as a Barrier to Success), I decided to write a RKG Duck filter which approximates AdGrouping. That is, given a list of keywords, write a filter which yields a signature which clusters similar phrases.
I chose a rudimentary algorithm: for each phrase, remove stop words, stem, alphabetize, and crush into a signature. It took me just under ten minutes to code it.
Here’s a 90 second preview video showing the filter in action:
And here’s a link to the full 10 minute video. It covers installing RKG Duck, using CPAN modules, and writing the stemming AdGroup filter.

Note: this example is a demonstration of what one can do with RKG Duck. This isn’t how our firm builds AdGroups — we don’t recommend building out phrases then AdGrouping later. Rather, the right approach to build campaigns is to go through every relevant URL on the site; build out rich keywords for each URL; assign targeted copy, smart match types, and sensible initial bids; then adgroup them appropriately. As George mentioned, there’s significant benefit in databasing ads in a richer taxonomy than the simple Campaign >> AdGroup >> Term hierarchy.

Hey, this looks great. I installed the duck, grabbed Perl active state and have the built in .pl files working properly…but I can’t get the adgroup filter to work. The Youtube video was a bit distored - can you confirm this code?
use strict;
use Text::English;
my %stop = map {$_=>1} qw(
a about an are as at be by for from how i is it
of on or that the this to was what when where who will with the);
while () {
chomp;
my @w=split( /\s+/. $_);
@w = grep { ! $stop{ $_} } @w;
@w = Text::English::stem(@w);
print join(”. $ @w), “\n”;
}
I found a few errors, now it just pastes what I copied, but the result is noting.
Hi Jeff —

Hi.
I downloaded your duck tool however the software does not capture the filters that come along with the download, ie: on the left side of the user-interface, there are no filters which I can click on, there is just an empty white space. I thought I was doing something wrong however a friend with strong technical skills also had the same problem. Any advice??
Thanks so much!
Thank you for offering this tool, but I also can’t make out the code in the adgroup stemming video. Any chance you could post this for download? I would love to experiment with it.
