"They look more professional" is a feeling, not a diagnosis — but the feeling is usually caused by a small number of specific, nameable factors.
Low-resolution, poorly lit, or stock photography is frequently the single biggest driver of a site "feeling" less professional — often more impactful than layout or colour choices, and comparatively inexpensive to fix.
A site with consistent typography, spacing, and colour use across every page often reads as more professional than a more elaborate but visually inconsistent one — consistency is a simpler, more achievable target than complexity.
Vague, hedging copy can unconsciously read as less professional than direct, specific claims — the confidence of the messaging itself contributes to the overall impression, independent of visual design.
Consistent formatting, working links, and an absence of obvious errors signal care — small details a visitor may not consciously notice individually, but that collectively shape the overall impression of professionalism.
