Which of the following is considered a disadvantage of self-publishing?

Self-publishing allows authors to maintain significant control over their work, including creative aspects and profit margins. However, one of the notable disadvantages of this model is the limited marketing and promotional reach. Traditional publishing houses often have established relationships with distributors and access to extensive promotional channels. This can significantly impact the visibility of a self-published work, as authors may need to rely on personal networks, social media, and grassroots marketing efforts, which can be less effective in reaching a broader audience. Without the backing of an established publisher, self-published authors might find it challenging to achieve the level of exposure that their work needs to succeed in a competitive market.
