All the marketing you do as an interior designer will be wasted if you do not clearly explain why you are the right fit for a client and are different than other designers.
If you do residential interior design, you are not just an interior design for homes. If you work best with young families, state it. If you work better with retired couples, state it. If you work exclusively in Dallas, Texas in 1 specific style, make that clear. Otherwise, you will not stand out among your competitors. Your photos do not tell the whole story.
