I like that they are very thorough in their research during each stage before implementation begins! They have been able to help us with both B2B as well ancillary marketing channels such has Facebook Ads & Google Adwords/Analytics optimization (not just SEO).
The team is always helpful when it comes time do ask questions or seek clarification if needed - which happens quite often because there's so much information being thrown at me every day haha :) Would love more data about what percentage gets conversions etc after implementing any given solution recommended by them but overall great experience thus far!!
