Important keywords with low CTR

Should they go in a seperate campaign?

Lets assume I'm targetting the phrases "red widgets", "blue widgets", "green widgets", etc. which are not searched for that often.

I create a set of ad's that don't get may impressions but have a high CTR which I put in one campaign.

Now "widgets" is searched for much more often, so I create an adword which includes the phrase 'coloured widgets only'. In the hope that only people interested in coloured widgets will click. This means the number of impressions is high, but CTR is low.

My question is where should this adword go? in the first campaign, where it will lower the overall CTR, or in a seperate campaign?

Because your testing out something that could be expensive, as widgets gets a lot more impressions - I'd put it in its own campaign to control its spend.

Your first campaign, you want to show 24/7 regardless of spend as it's so targeted - so you can set your daily budget high on this one.

For broader keywords, I like to seperate them out in their own campaigns so I can control their spend during a test period to see how well the keyword preformed, and to make sure I don't go broke during such a trial period.

Thank you eWhisper that confirms what I was thinking.
