So my point is. That there is no need to limit the languages that your adwords campaign is targetting.
If your keyword for an ad is "pickled eggs". Then you will only be getting people who are searching with an english phrase anyway.
What do you think?
We where running a Swedish camaign where someone forgot to set the language to Swedish. A few of our keywords turned out to be very frequent which made our ad turn up a whole lot mor than we had expected.
Now, since the ad was in Swedish, it got a very low CTR from say USA, Japan, Australia... and eventually the keyword was disabled.
This actually be a problem even for pickled eggs. Who knows wat eggs means in Swahili?
