If you just spend some quality time thinking about how your keywords could be ever possibly be used in a phrase by a consumer, and think of any other words that could logically also be in that phrase, but would not apply to your product or service, that would give you a good starting point for your negative word list, even without seeing it actually used in a particular search. Unfortunately, many advertisers simply do not have the creativity to do this, or try to make the excuse that they don't have time to do it. Therefore, it is often necessary to scour web logs on a daily or weekly basis, to see what searches are in fact being used by consumers, and to develop negative keyword lists on the fly. Unfortunately, the reactive approach will generally not keep your ads from getting a non-relevant impressions, which means that the ad's creative (content) is the only barrier to non-relevant clicks. And while that may be OK, it certainly doesn't do your overall CTR rates any good.
For example: A consumer could do a search on "red fancy widgets with wings". I might have a broad match keyword phrase: fancy widgets, and my fancy widgets could be red or any other color, but would never have wings. There may really be red fancy widgets with wings somewhere, but I don't sell them, so I don't want my ad displayed for that search. So, knowing this, or if/when I ever see this in my web stats, the obvious new negative keyword would be -"wings". However, I would probably be more pro-active, and also make "winged", and "wing" and "winging" additional negative keywords, since a consumer could possibly use those variations as well, even though I didn't see it in a particular search.
The point is that the process of thinking about and implementing negative keywords has to be creative and proactive, to some extent, because you want to prevent the non-relevant impressions and non-convertible clicks from ever occurring in the first place. The only way to do that in a reliable way, is to make sure that your ad is never displayed for non-relevant consumer searches.
The desired end result of course, is that if your ads do not get impressions for non-relevant searches, two things will happen:
1) Total impressions are reduced, improving CTR, which we all now know (or believe) is one QS factor. The impressions your ads do get appear to be more relevant to the consumer, which is also the job of your creative.
2) Since your ad is not displayed for non-relevant searches, your overall AdWords costs would be reduced and conversion rates should be improved. Consumers who are not looking for your specific product or service, but perhaps one that seems similar, cannot click on your ad, because it isn't there in the first place!
Because of my proactive approach to this, plus long term experience in the vertical I specialize in, my clients tend to get very good CTR and conversion results quickly, which increases positive client references and referrals. And by reducing the time I would otherwise have to spend on daily web log evaluations for new campaigns, I can also do the jobs quicker and cheaper for my clients, and have more time to allocate to chargeable consulting services and personal recreation.
Google "dozer sandals" (a model of Teva brand sandals), see the ads there for earthmoving bull dozers... those advertisiers need to add sandal and sandals as negs!
Yahoo's new platform only allows 50 negs per, idiotic move. I have some in G with over 700 negs.
Fastest way to find the bulk of them? Go to eBay and Amazon, search for mainline words (the bulldozer company above should have searched for "dozer"), flip through hundreds of pages of stuff and pull the good neg words from the product titles and descriptions.
And mine your logs monthly for keywords culling good negs from there (keeping in mind this isn't ideal because the sandal searcher rarely clicks on the bulldozer ad - logs should be considered a sparse source for good negs).
Therefore, it is often necessary to scour web logs on a daily or weekly basis, to see what searches are in fact being used by consumers
I also periodically check in Google (and Yahoo and MSN now) to see who else is running ads on some of my keywords - if they AREN'T competitors, then I know I might need to add to my ever-growing list of negatives.
I notice I'm getting some clicks from content search

Content network is simply impossible to control or target.
