You can batch all sorts of tasks together – such as taking a day to get together your whole months/year photography. Or writing all your email newsletters for the month at the same time, rather than waiting a week in between.
You can then see what needs to be created, you can make a list of how many photos, quotes, reviews, stories or videos you need.
This is usually the longest part of the process, but knowing in advance what you need can help you focus on the task at hand. Batch similar content together, so take time to find or take all of your photography, then copy etc.
By building a library of graphics, copy and photos you are able to save time in the future. Make sure you and your team have easy access to this, and it is secure.
