Furthermore, it is likely that your competitors are using an agency, so to get ahead it is wise to also seek out help. If you come across a company that claims they can help you reach number 1 on Google overnight or that they know all of Google’s algorithms, then they might not be a proper agency.
It is also useful to avoid companies that offer free services as they are likely just trying to get you to pay for something else down the track. A proper agency will also still encourage your business to use other marketing strategies.
SEO is just one piece of the puzzle, and all pieces are equally valuable. A reputable company will also ensure that good quality links are shared in order to avoid a penalty from Google.
At the end of the day, a legitimate company such as our team here at SEO Shark will use honest methods that reach organic customers and will never make any unrealistic promises.
