Well, you could ask a hundred people and see how many know about the campaign.
Then you would have a ratio of 'know about the campaign' and 'don't know about the campaign.'
It could be for example 67 know and 33 don't. So the awareness ratio would be two to one (2:1). Alternatively, you could express this as a percentage of those surveyed, so in this case there would be 67% campaign awareness at the time the survey was taken.

You can say specifically how many people knew about the campaign in whichever way you have calculated it, for example, 'the recognition rate of the campaign was high. 80% of people knew about it!'. Or use the final example to say the percentage rate. You can also use phrases like the first to express that there was high recognition for the campaign. You could say 'the campaign had a lot of recognition' 'most people knew about the campaign', but these are less specific in terms of numbers.
具体的にどのくらいの人がキャンペーンについて知っていたのか伝えることができます。
例えば、
'The recognition rate of the campaign was high. 80% of people knew about it!'（キャンペーンの認知率は高かったです。80％の人が知っていました）
あるいは、最後の例を使ってパーセンテージを伝えることもできます。
また、一つ目の例のように「キャンペーンの認知率は高かった」と表すこともできます。例えば：
'The campaign had a lot of recognition'（キャンペーンの認知率は高かった）
'Most people knew about the campaign'（ほとんどの人がキャンペーンについて知っていた）
ただ、これらは数字についてより曖昧です。
