While there are many "veterinary website design and marketing companies" claiming to work in the animal hospital industry exclusively, you should know that many of these companies also work with other small businesses such as chiropractors, dentists, obstetricians, and podiatrists. Considering these agencies to market your veterinary practice online will put your digital ROI at risk as they simply cannot understand the intricacies of veterinary digital marketing.
Not knowing your animal hospital's specific goals and targeted audiences makes it difficult for a firm to execute a marketing strategy successfully. Without this foundation, additional time would be needed on your end to manage the process and provide instruction about the industry - time that you simply don't have.
It's unrealistic to believe that one person in your veterinary hospital can handle everything. He or she would need to be knowledgeable about veterinary medicine and all aspects of digital marketing. Even worse, if they leave your animal clinic, you're really exposed.
