Minimum keywords

Is there a minimum amount of keywords required for a adwords campaign for google to show the ads?

 

You need at least one keyword.

 

yes its necessary that min. 1 keyword is required to run your ads but no limit for max. keywords its depends upon your budget.

 

Not strictly true - if you only had placement campaigns, you wouldn't even need one

 

You are lucky if you got a one-word-campaign
However, if its working, you should put it in "", and make other campaign without it. It will bring you better results.

I like your comment! Not quite what I expected, but it opens up new perspectives!

 

You minimum required one keyword but you can use two or three also depending upon your budget and length.

 

no minimum. However, once you grow to have thousands of keywords, you won't be creating compaigns for every keywords. It is better to put keywords close in meaning into a single compaign

 

You can create a campaign without any keywords. Or you can set up an ad campaign and put it in hold... same results.
