  11. Basic Web Design • Let’s take a closer look page by page

  12. 1

  13. 1 • What site is this? • Logo in top-left corner denotes the site • Another logo at top-right to reinforce • examples of SITE BRANDING (E1)

  14. 1 • What kind of site is this? • Shopping cart icon • Tab row content & categories on left • Prices in content area • UP-FRONT VALUE PROPOSITION (C2) • example of PERSONAL E-COMMERCE (A1)

  15. 1 • What can I do here? • Welcome for new visitors • Tab row / Search on top • “Categories” • Prices • Examples of OBVIOUS LINKS (K10)

  16. 1 • Most important info visible without scrolling • ABOVE THE FOLD (I2)

  17. 2

  18. 2 • What site am I at? • Logo in upper-left reinforces brand, can click to go to home • Same font, layout, color scheme also reinforces • examples of SITE BRANDING (E1)

  19. 2 • Where am I in the site? • “Home > Music” are LOCATION BREAD CRUMBS (K6) • TAB ROW (K3) says “Music” • Album cover, “Product Highlights”, and CD cover

  20. 2 • Can I trust these sellers? • Who am I buying from? • Are they reputable? • What about shipping?

  21. 2 • The Fold • Hmm, what’s below here?

  22. 2 • Impulse buy • PESONALIZED RECOMMENDATIONS (G3) • About this album • Lots of unused space • Still more info below…

  23. 2 • Is this product any good? • Editorial reviews • Customer reviews • RECOMMENDATION COMMUNITY (G4)

  24. 3

  25. 3 • What site am I at? • Logo in upper-left • Colors, layout, font • examples of SITE BRANDING (E1)

  26. 3 • Where am I in the site? • Last link clicked was “Buy!” • “Shopping Cart” and “Proceed to Checkout” reinforce that this is “the right page” • SHOPPING CART (F3)

  27. 3 • Cross-selling • Possibly a pleasant surprise • Impulse buy • CROSS-SELLING & UP-SELLING (G2)

  28. 3 • What am I going to buy? • Easy to remove • Easy to move to wishlist • How much will it cost? • Shipping costs there, no nasty surprises • SHOPPING CART (F3)

  29. 3 • What can I do? • “Proceed to Checkout”HIGH VISIBILITY ACTION BUTTON (K5) • Visually distinct • 3D, looks clickable • Repeated above and below the fold

  30. 4

  31. 4 • What if I don’t have a User ID? • What if I forgot my password? • SIGN-IN/NEW ACCOUNT (H2)

  33. 5 • What site? • Logo, layout, color, fonts • Where in site? • Checkout, step 1 of 3 • “Choose shipping address” • QUICK-FLOW CHECKOUT (F1)

  34. 5 • Note what’s different (?) • No tab rows • No impulse buys • Only navigation on page takes you to next step • This is a PROCESS FUNNEL (H1) • Extraneous info and links removed to focus customers

  35. Quick-Flow Checkouts 6

  36. Quick-Flow Checkouts 6 • Last step of process • Step 3, “Place Order” • “Place my order” button • Two HIGH-VISIBILITY ACTION BUTTONS (K5) for fold

  37. Quick-Flow Checkouts 6 • No nasty surprises • Can see order • Total price is same as shopping cart • ORDER SUMMARY (F7)

  38. Quick-Flow Checkouts • Easy to change shipping and billing • Easy to save this info • Easier to setup info in context of specific task • Clear to customers why this info is needed

  39. Design patterns

  40. Design = Solutions • Design is about finding solutions • Unfortunately, designers often reinvent • Hard to know how things were done before • Why things were done a certain way • How to reuse solutions

  41. Design Patterns • Design patterns communicate common design problems and solutions • First used in architecture [Alexander] • Ex. How to create a beer hall where people socialize?

  42. Design patterns communicate common design problems and solutions • First used in architecture [Alexander] • Ex. How to create a beer hall where people socialize?

  43. Using Design Patterns • Not too general and not too specific • use a solution “a million times over, without ever doing it the same way twice” • Design patterns are a shared language • for “building and planning towns, neighborhoods, houses, gardens, & rooms.” • Ex. Beer hall is part of a center for public life… • Ex. Beer hall needs spaces for groups to be alone… ALCOVES

  44. A Web of Design Patterns (8) Mosaic of Subcultures Cities & Towns (31) Promenade (33) Night Life (90) Beer Hall Local Gatherings (95) Building Complex Interiors (179) Alcoves (181) The Fire

  45. Web Design Patterns • Now used in UI design • Communicate design problems & solutions • how to create navigation bars for finding relevant content… • how to create a shopping cart that supports check out… • how to make e-commerce sites where people return & buy…

  46. NAVIGATION BAR (K2) Problem: Customers need a structured, organized way of finding the most important parts of your Web site

  47. NAVIGATION BAR (K2) First-level navigation Link to home Second-level navigation Solution diagram • captures essence on how to solve problem

  48. Pattern Groups • Our patterns organized by group • Site genres • Navigational framework • Home page • Content management • Trust and credibility • Basic ecommerce • Advanced ecommerce • Completing tasks • Page layouts • Search • Page-level navigation • Speed • The mobile web

  49. PROCESS FUNNEL (H1) • Problem: Need a way to help people complete highly specific stepwise tasks • Ex. Create a new account • Ex. Fill out survey forms • Ex. Check out
