You'll need content to some extent across the whole journey, but your research should help inform key stages. By understanding what content your customers/users need at each stage (and how good your existing content is at each stage) you can then decide where to focus your efforts. We often find that the latter stages in the customer journey (for example 'Use' or 'Advocacy' are forgotten or focussed on less), therefore it might be the case you need to focus on these more. Use your data and also your overall business objectives to help provide the direction. For example, if you have no problem in getting people to your website, but the conversion rates are lower, then you may need to focus on your website content including CTAs.
