Before moving your content into a new site, we encourage you to take stock of what content exists on your current site and develop a plan for migrating it.
Performing a content inventory and analysis is an excellent way to determine what content you have on your site, what needs to be updated, what can be removed, and what new content you need to create.
Although any site can benefit from this exercise, this process is especially important for large and complex websites, and for sites that have existed for several years. These sites will commonly have pages that are out-of-date or no longer needed.
To help you through this process, Institute Communications provides a step-by-step guide to auditing and analyzing your content and a content audit template.
