Say who you are for, not what you do
Every firm offers the same services, and the only thing a visitor can use to distinguish one is who it works with.
A list of services tells a visitor nothing, because every competing firm lists them too. The information they need is whether this firm understands businesses like theirs.
Naming the client is more useful than naming the service. The industries you concentrate in, the size of business you suit, the situations you handle regularly.
It feels exclusionary and it is, deliberately. A firm that appears to be for everybody is for nobody in particular, and a visitor who recognizes themselves stops comparing.
The specialization usually exists already and is invisible. Most firms have a concentration of clients in something and have never said so on the website.
Claims about specialization and expertise are governed by state boards and the rules are not uniform, so how this is phrased is worth confirming rather than composing for effect.
