hi, my DP friends. i got a question. i have two keywords in the same group. [clip in] & [clip-in]. after testing several days, only one of the two show numbers of clicking and impressions, while the other not. my question is: are the same keywords in adwords system? this is just what i was guessing. i need a professional answer. but thanks for any reply.
Google tends to treat punctuation as if it were a space. I imagine what's happening here is that they're registering as the same on the system.
Actually, in Adwords those are two separate keywords. The one without impressions is simply because less people are searching that way. You mention just a few days which is not long and you don't mention the number of impressions for the other keyword. As for the search engine itself, punctuations are ignored as well as some words and numbers (depending on how you search). Dashes are generally ignored too but the words can be concatenated (un-known would equate to unknown). But in Adwords, un-known and unknown would trigger properly if you have them as separate keywords. But if you had only unknown, it would trigger for searches of un-known, most likely. But just to be sure and catch those searches as well as gather data on how people search, use both.
Are you sure that's always the case for all punctuation? I'm pretty certain that periods are turned into spaces and hashes are ignored completely, based on the data I have. I would have guessed that receiving no impressions whatsoever would be an indication that something similar was going on. I guess the way to prove that they're treated as unique keywords would be if they both got impressions on their own merits. There's certainly no harm in leaving them both there, in any case.
