It also hurts AEO, not just SEO
As search increasingly moves toward Answer Engine Optimisation (AEO), clarity matters even more.

Search engines, voice assistants, and AI-driven results are looking for clear, direct answers to questions like:

     •  What does this organisation do?
     •  Who is this ser-vice for?
     •  What problem does it solve?
Generic titles and headings make it harder for your content to be surfaced as a clear answer. Clear, descriptive headings make it easier for your site to be understood, summarised, and recommended by answer-driven systems.

In short, vague language performs poorly in an answer-first world.
