The team at GS are very knowledgeable about social media platforms like Facebook & Instagram with amazing skills for creative design work! They also have great connections within other agencies which helps us get things done quickly without having too many people involved or processes slowing down projects etc..
I would say it's difficult finding someone who can do all aspects well but this isn't an issue as they're able/willing enought resources - so not much else really :) We've been working together over 2 years now doing various campaigns from awareness through engagement using different channels such has FB ads + content creation via blogs / videos across multiple industries including beauty products (e-commerce).
