The service they provide is exceptional! They have done wonders for us with social media advertising as well optimizing our website content. There's been no downside so far as I can tell; however if there was it would be addressed immediately by their team members who are very responsive &-knowledgeable about SEO/SEM issues related web site performance (or lack thereof). We've seen significant increases in traffic from search engines when searching specific terms relevant to one or both products offered through the websites hosted at AVL - which translates into more sales opportunities being generated per day via Google AdWords campaigns targeting those keywords.
