It used to be fashionable to think that web pages were suitable for goods or services that needed to be sold quickly. That is, for high-speed sales. In fact, nowadays, frontends are often used for a wide variety of niches, from repairs to passports, from apartment sales to bicycle rentals. Naturally, when it comes to complex or expensive products, the purchase does not happen immediately on the landing. In the case of repairs, the target action is "call a specialist to calculate an estimate", in the case of apartment sales "sign up to visit the construction site", and in the case of many products, you can offer visitors "order help to the master in selecting a closet" or "Consultation with a specialist. Responding to the question, I still note that it is worth thinking carefully before making a landing page for very complex services, where the decision to order is time-consuming. For example, when it comes to complex insurance or financial services, or, for example, large industrial sales. For such things, a turnkey corporate website that describes the history of the company/plant, presents the mission and lots of articles to explore would still be better suited.
