Social network aggregation is a way to collect and organize information from different social media platforms in one place. This helps people save time from having to look up information on multiple websites. For example, if you wanted to find out what your friends have been posting on Facebook, Twitter and Instagram, you can use a social network aggregator to show you all their posts in one place. This way, you don't have to check each website individually, and you can read what your friends have been up to all in one spot.
