Great well-rounded agency
I used Fang for mainly search with a number of companies, having them tackle pickup from some internal teams that were underperforming. On each, they were able to quickly restructure and refocus campaigns to drive rapid increases in volume and contribution. I have also used them for SEO analysis on a few other instances and their insights have been actionable and valuable.
I know they also handle many other aspects of online marketing and woudl have confidence in bringing them on to help with client strategy and execution if the ability to work with them again arises.
