Will adding search term to ad body boost keyword relevance, or is once in the ad title enough to cover that?
Yes, but it's the CTR impact that is most important. Getting a click is 2 steps:
1) get noticed (bold)
2) compelling ad text
the count of times the word is used can be overdone - test variants to learn what works best.
