E-commerce Web Design: Product/Service VS. Layout

I came across the article 10 Rock Solid Website Layout Examples which has great explanations and examples of different web layouts. Johnson gives an example of a grid and next he gives an example of an actual website to compare it to. I encourage any designers to check out this article for inspiration or just to gain some general knowledge about website grids. My question is what kind of layout does a business that sells products likely to use and what kind layout does a business that sells services use. How might the layouts be different from each other? I will start by explaining examples of different layouts and then talk about what types of products are more likely to use that layout.

Johnson's website layouts:

Sometimes the most simple of things can make the most impact. I believe that this is very true for all types of design, especially website design. The arrangement of elements on a page is something that can make or break a sale. The size and location of the call to action, using an intriguing photos at the top of the page, the arrangement of objects in the virtual store, and the location of the shopping cart button can make a big impact. An example of a product website would be clothing, amazon, sports gear, fishing supplies. Examples of service websites would be photography, technology sites, design, and marketing solutions.

Three Boxes
You may be thinking this is far too simple, but actually it is very effective. The three boxes can be filled with graphics or text. The larger box can be something like a slide show that features different products or services. The small boxes at the top can be used for logos, navigation, logins, and shopping cart links.
Product or service website? This website layout can be used for both e-commerce products and services. Products can be well-represented through images and if it is a website that provides services, professional photos that represent the business could be used. This would work well for the homepage of a product website and it could possibly be the product listing page of both products and services.

3D Screenshots
This layout uses a 3D slide show effect that one can flip through. The slideshow can consist of screenshots, photographs, and text. The small boxes at the top could include the logo, navigation, and shopping cart options.

Advanced Grid
The advanced grid can consist of many different elements. Once again, the gray boxes represent text or graphics. The boxes at the top represent logos, navigation, login, and shopping cart options.

If there are many products, like a clothing store, there is a lot of room for creativity and being able to fit a lot of products on the page. This type of layout would work best for a homepage or even a product listing page.

Featured Graphic
The featured graphic website consists of a simple photo with text that relates to it. It is great for a site that does not have much content or graphics. The smaller boxes would consist of a logo, navigation, and shopping carts.
