One possible argument against this is that it presents a narrow and overly simplified view of Instagram marketing. While it is true that setting clear goals, understanding the audience, and tracking and refining performance are important aspects of any marketing strategy, there are many other factors that can affect the success of an Instagram marketing campaign. For example, the quality and relevance of the content, the frequency and consistency of posting, the use of hashtags and other features of the platform, and the overall branding and aesthetic of the account can all play a role in attracting and engaging followers on Instagram. Additionally, the paragraph does not mention other potential objectives of an Instagram marketing strategy, such as building awareness, increasing website traffic, or improving customer service.
