Squarespace's templates solve the "does this look legitimate?" problem on day one, and that is genuinely valuable. The trouble starts when the template's polish creates a false sense of completion. The page looks ready, so you launch it — but "ready" and "persuasive" are different standards. A page can look perfectly professional while failing every conversion test: a vague headline, no clear next step, trust signals missing, and a layout that prioritizes symmetry over hierarchy.
The deeper issue is limited control. Squarespace deliberately constrains what you can change — which keeps pages looking good but makes it harder to do the specific things that drive conversion: removing navigation on landing pages, building a custom hero layout, adding inline trust signals exactly where they need to be, or restructuring the page around a single action instead of a template's default section order.
