Do low impression keywords negatively affect your entire campaign?

[sunseven]

I've been running a campaign for the last 3 weeks with about 5,000 keywords and of course only a handful of them are driving traffic. Most of the other keywords have zero impressions/clicks. So I wanted to know if having these no-impression keywords in the same campaign and/or adgroup as the other nicely performing keywords negatively affects the overall quality of your campaign/adgroup?

honestly i don't think so and I do have some of them like that. It does not mean -to my views- that they are not good keywords.

A specific keyword will not negatively affect another keyword. It will either work successfully as a keyword in itself, or not - it will not do harm. However, the content you provide around the keywords are also very important. Keywords are given value according to the relevance they have in the content they appear

Never! So Don't Worry about it.

No it will not, your targeted keywords should be targeting your SPECIFIC market or audience. If some keywords are not generating any traffic then the market is low or not profitable OR the COMPETITION is very fierce, choose another niche or improve your SEO strategies.
