Depending on the size of your business, you may lack the resources, knowledge and expertise to optimise SEO by yourself. There are many conflicting sources of information out there on the internet that could mislead or confuse readers.
SEO agencies are however, certified experts in this field. Possessing an abundance of expertise and knowledge in the workings of SEO, they are qualified to manage SEO in a more efficient and effective manner than the layman. Engaging a SEO agency also frees up your time and resources, thus allowing them to be diverted to other aspects of your business.
