The best website packages cover your design and functionality bases. On the design side of things, they account for things like brand alignment, photography, messaging, page layouts, first impressions, and user experience. On the functionality side of things, they account for things like mobile optimization, website speed, search engine optimization (SEO), and third-party integrations (e.g., scheduling, payment processing, email list management).
The best website design companies will typically include these items in their standard website design package. However, many of the discount web design companies cut corners that limit your website design, functionality, or both.
