There are certain kws that I put in as a negative when starting a campaign. Why? Because most of those kws are just gonna increase my impressions and very likely not get me any impressions.  And when running a content network campaign, there are sites that I list as negative – you will see why.

First let me list the kws:

contact, phone, phone number, scam, adult, affiliate, articles, porn, naked, games, kws, kw, keyword, pic, photo, pics, photos, keywords, affiliates, scams, 800, complain, complaint, create, lp, landing page, ad, ads, article

I add more depending on the niche, but these are general terms I add.

Sites that I block are:

ripoffreport, complaintsboard, myspace, wafflesatnoon

Hope it helps.
