Welcome to the Q&A Forum

Hey Robert! Campaign updates happen on a weekly basis on the same day every week. If you want to see changes before your next scheduled crawl, you can head over the Research Tools page and run a crawl test. This is a bit more limited in that it will only crawl up to 3k pages and is cached for a 24 hour period, but is the best bet if you don't want to wait. Hope this helps!
