1 Process The first step in designing any web site is to define your goals. Planning a web site is a two-part process: first you gather your development team, analyze your needs and goals, and work through the development process outlined here to refine your plans. Next you create a project charter document that details what you intend to do and why, what technology and content you’ll need, how long the process will take, what you will spend to do it, and how you will assess the results of your efforts. The project charter document is crucial to creating a successful site: it is both the blueprint for your process and the touchstone you’ll use to keep the project focused on the agreed-on goals and deliverables. Thoroughly understand and communicate your top three goals Know your audience Web analytics as a planning tool Design critiques Content inventory Place yourself in the background Work from a suitable design Do not overwrite Prefer the standard to the offbeat Be clear Do the visuals last Revise and rewrite Be consistent Do not affect a breezy manner Degrade gracefully Do not explain too much Make sure the user knows who is speaking The Site Development Process Every significant web project poses unique challenges, but the overall process of developing a complex web site generally follows six major stages that you should think through before crafting your final project planning and proposal documents: 1. 2. 3. 4. 5. 6. Site definition and planning Information architecture Site design Site construction Site marketing Tracking, evaluation, and maintenance Small is good. Plan the work and then work the plan. 2 Universal Usability Usability is a measure of effectiveness. It describes how effective tools and information sources are in helping us accomplish tasks. n designing web sites our job is to reduce functional limitations through design. When we aim for universal usability, we improve the quality of life for more people more of the time. On the web, we can work toward universal usability by adopting a universal design approach to usability. Accessibility Principle One: Equitable Use, Principle Two: Flexibility in Use, Principle Three: Simple and Intuitive Use, Principle Four: Perceptible Information User research 3 Information Architecture Organize the site content into taxonomies and hierarchies of information; Communicate conceptual overviews and the overall site organization to the design team and clients; Research and design the core site navigation concepts; Set standards and specifications for the handling of html semantic markup, and the format and handling of text content; and Design and implement search optimization standards and strategies. Content Inventory Navigation - Long Tail Phenomenom Sequence, Hierarchy, Web Linked Sites Canonical form in web pages: Where to put things, and why 4 Interface Design Navigation isn’t just a feature of a web site, it is the web site, in the same way that the building, the shelves, and the cash registers are Sears. Without it, there’s no there there. —Steve Krug Wayfinding has four core components: 1. Orientation: Where am I am right now? 2. Route decisions: Can I find the way to where I want to go? 3. Mental mapping: Are my experiences consistent and understandable enough to know where I’ve been and to predict where I should go next? 4. Closure: Can I recognize that I have arrived in the right place? Clear Navigational Aides, No dead end pages, direct access, simple and consistent, Design integrity and stability, Bread crumb trail for navigation? Each Page should be freestanding with who, what, when, and where! Summary: Information design guidelines Every web page needs: An informative title (which also becomes the text of any bookmark to the page) The creator’s identity (author or institution) A creation or revision date A copyright statement, Creative Commons statement, or other statement of ownership to protect your intellectual property rights At least one link to a local home page or menu page, in a consistent location on all pages The home page url Most web pages should also incorporate these additional elements: An organization logo or name near the upper left corner, with a link back to your home page Navigation links to other major sections of your site At least one heading to identify and clarify the page content Mailing address and contact information or a link to this information Alternate (“alt”) text identifying any graphics on the page Include these basic information elements and you will have traveled 90 percent of the way toward providing your users with an understandable web user interface. 5 Site Structure SEO Focus on your titles and keywords The ideal optimized web page has a clear editorial content focus, with the key words or phrases present in these elements of the page, in order of importance: Page titles: titles are the most important element in page topic relevance; they also have another important role in the web interface—the page title becomes the text of bookmarks users make for your page Major headings at the top of the page (<h1>, <h2>, and so on) The first several content paragraphs of the page The text of links to other pages: link text tells a search engine that the linked words are important; “Click here” gives no information about the destination content, is a poor practice for markup and universal usability, and contributes nothing to the topical information of the page The alternate text for any relevant images on the page: accurate, carefully crafted alternate text for images is essential to universal usability and is also important if you want your images to appear in image search results such as Google Images and Yahoo! Images; the alternate text of the image link is the primary way search engines judge the topical relevance of an image The html file name and the names of directories in your site: for example, the ideal name for a page on Bengal tigers is “bengal-tigers.html” Keywords, directory names, meta tags, easy to navigate, 6 Page Structure The experienced web designer, like the talented newspaper art director, accepts that many projects she works on will have headers and columns and footers. Her job is not to whine about emerging commonalities but to use them to create pages that are distinctive, natural, brand-appropriate, subtly memorable, and quietly but unmistakably engaging. —Jeffrey Zeldman Book design, typography, and the larger world of print publishing are enabled by established conventions and standards for print publication. With “web standards” methods for building sites, with carefully validated and universally accessible xhtml and css, we now have excellent technical standards. Unfortunately we’re still in an awkward, adolescent stage for web publishing, editorial, and design standards, but clear patterns and user expectations a The home page Designing an effective home page can seem daunting, but if you’ve already thought through the fundamentals of your site navigation and have done the hard work of creating internal and secondary page templates, you have a great head start. Designing the home page layout last allows you to acknowledge the unique introductory role of the home page but places the design firmly within the larger navigational interface and graphic context of the site. Home pages have four primary elements: Identity Navigation Timeliness, or content focus Tools (search, directories) Good home page designs always blend these four factors. How you blend them depends on the overall goals of your site, but most good home pages do not balance all four elements equally. Home pages often have a distinctive theme in which one factor dominates. Amazon’s home page is all about navigation to products. Yale University’s home page projects identity. The Atlantic is dominated by timeliness and content. Google’s famously lean home page is all about tools. An effective home page can’t be all things to all people. Decide what your priorities are, and build a home page that gives the user a clear sense of theme and priority (fig. 6.13). re emerging from the chaos. 7 Page Design We seek clarity, order, and trustworthiness in information sources, whether traditional paper documents or web pages. Effective page design can provide this confidence. The spatial organization of graphics and text on the web page can engage users with graphic impact, direct their attention, prioritize the information they see, and make their interactions with your web site more enjoyable and efficient. The primary purposes of graphic design are to: Create a clear visual hierarchy of contrast, so you can see at a glance what is important and what is peripheral Define functional regions of the page Group page elements that are related, so that you can see structure in the content Crowded pages confuse the figure-ground relationships of page elements by creating an ambiguous field of visual texture, with little contrast to draw the eye and few landmarks to help the user understand content organization. Crowded elements also cause 1 + 1 = 3 effects, adding visual confusion. Proximity and uniform connectedness are the most powerful Gestalt principles in page layout; elements that are grouped within defined regions form the basis for content modularity and “chunking” web content for easy scanning. A well-organized page with clear groups of content shows the user at a glance how the content is organized and sets up modular units of content that form a predictable pattern over pages throughout the site Consistency, Contrast (fonts, colors, etc.)simplicity, style, whitespace, don’t overuse contrast Proximity Elements that are close to each other are perceived as more related than elements that lie farther apart (a, below). Similarity Viewers will associate and treat as a group elements that share consistent visual characteristics (b, below). Continuity We prefer continuous, unbroken contours and paths, and the vast majority of viewers will interpret c, below, as two crossed lines, not four lines meeting at a common point. FIXED VS. FLEXIBLE PAGE WIDTHS 8 Typography Consistent, Legible, Contrast, Choosing typefaces The most conventional scheme for using typefaces is to use a serif face such as Times New Roman or Georgia for body text and a sans serif face such as Verdana or Arial as a contrast for headlines. Various studies purport to show that serif type is more legible than sans serif type, and vice versa. You can truly judge type legibility only within the context of the situation—on the screen, on paper—as users will see your web page. You may use either a variation of the serif font or a contrasting sans serif face for the display type. It is safest to use a single typographic family and vary its weight and size for display type and emphasis. If you choose to combine serif and sans serif faces, select fonts that are compatible, and don’t use more than two typefaces (one serif, one sans serif) on a page. The most useful fonts that ship with the Apple Macintosh and Microsoft Windows operating systems are reproduced here, differentiated by their effectiveness on-screen and on paper. Remember that many Macintosh users who have installed Microsoft Office will have Windows fonts installed on their systems (fig. 8.9). 1. Readers like large type more than most designers do. It’s not just the taste for graphic subtlety that drives the dichotomy: web designers are usually under great pressure to “cram in as much as possible,” and smaller type means more words per inch. 2. Generous leading (line spacing) is a key to legibility. Larger type helps, but the data suggests that a moderate type size—11 points—and a standard 13 points of leading yields the best balance of type size and overall reading comfort. Display Typography with Graphics 9 Editorial Style Segment the text for easy scanning, Use descriptive headings, Highlight important words and sections, Use the inverted pyramid, Structural markup – h1 and h2 tags, etc. Prose style For general advice on clear, concise writing, it is hard to beat George Orwell’s rules for writing: Never use a metaphor, simile, or other figure of speech that you are used to seeing in print. Never use a long word where a short one will do. If it is possible to cut a word out, always cut it out. Never use the passive where you can use the active. Never use a foreign phrase, a scientific word, or a jargon word if you can think of an everyday English equivalent. Break any of these rules sooner than say anything outright barbarous. Front-load your content, Stick to the point,Cultivate a particular voice, Think globally, Use numerals for specific numbers whenever possible Keep readers on your page. Links are descriptive 11 Graphics First and foremost, consistent interface and identity graphics across a collection of web pages define the boundaries of a web “site.” Graphics as content Graphics serve a number of purposes as elements of content—along with and complementary to text content: Illustrations: Graphics can show you things, bringing pieces of the world into your document Diagrams: Quantitative graphics and process diagrams can explain concepts visually Quantitative data: Numeric charts can help explain financial, scientific, or other data Analysis and causality: Graphics can help take apart a topic or show what caused it Integration: Graphics can combine words, numbers, and images in a comprehensive explanation The parameters that influence the display of web graphics are the user’s display monitor and network bandwidth capacity. Screen resolution refers to the number of pixels a screen can display within a given area. Screen resolution is usually expressed in pixels per linear inch of screen. Most standard computer displays have resolutions that vary from 72 to 96 pixels per inch (ppi), depending on how the monitor and display card are configured. All major browsers have native support for gif and jpeg graphics, as well as the basic features of png graphics. Browsers with the Adobe Flash plugin support Flash vector graphics. In theory, you can use any of these graphic formats for the visual elements of your web pages. In practice, however, most web developers will continue to favor the gif format for most page design elements, diagrams, and images and will choose the jpeg format for photographs, complex “photographic” illustrations, medical images, and other types of images in which the compression artifacts of the jpeg process do not severely compromise image quality Advantages of GIF files gif is the most widely supported graphics format on the web gifs of diagrammatic images look better than jpegs gif supports transparency and interlacing Advantages of JPEG images jpeg achieves huge compression ratios, which mean faster downloads jpeg produces excellent results for most photographs and complex images jpeg supports full-color (24-bit, true-color) images Alt-text <img src="banner.gif" height="30" width="535" alt="Web Style Guide"> Color is the response of our eye and brain to various wavelengths of light. Readers with normal vision can sense wavelengths of light from 400 nanometers (near ultraviolet) to 700 nm (near infrared). Computer screens use an additive color system that combines phosphors of red, green, and blue primary colors, which, when added together in various proportions, produce the more than 16 million colors possible on RGB screens. The maximum brightness of all three RGB primaries produces white light on the screen. 12 Multimedia If you want a golden rule that will fit everybody, this is it: Have nothing in your houses that you do not know to be useful, or believe to be beautiful. —William Morris (Use it sparingly)
