The big question is whether you should or shouldn’t plan your podcast script and there are people who sit in both camps. Some believe that scripted podcasts make speech feel stiff and rehearsed, others believe it’s the key to being confident, concise and keeping the content flowing.
The answer is to plan, but to plan right, as it is nigh on impossible to create great content without some sort of planning, even the podcasts which sound ad-libbed are scripted and rehearsed to some level. However, don’t think that you need to produce a rigid script which you follow word for word, you can create a guide which gives you pointers and leads you through your topics. The power of planning is that it ensures captivating content which hooks listeners and keeps you focused.
