Best Practices for Website Designers and Developers

,

Creating functional, user-friendly and effective websites requires mastering and implementing key best practices across disciplines like design, development and analysis. When website creators learn and establish strong core competencies around simplicity, mobile optimization, clean code, testing and inclusive access, it sets a solid foundation for building high-quality digital experiences that can serve audiences reliably for years with proper iteration. Those that dismiss established website best practices often end up with digital properties full of obstacles that frustrate users, deliver inconsistent business results and require constant rework just to keep afloat. By understanding the rationale behind these essential website development principles coupled with practical guidance for implementation, digital teams can significantly improve online interfaces and outcomes. The following set of defined best practices distills key disciplines down to their basic principles and proven methods for transforming websites from difficult digital burdens into sustainable assets.

Simplicity is Key

Keeping site designs simple and minimalistic improves usability. Eliminate unnecessary visual clutter like too many fonts, colors, animations. Use plenty of white space. Design elements should guide users efficiently to content and calls-to-action. Implement simplicity by starting with pen and paper wireframes focused solely on site goals and key tasks.

  • Identify the core purpose and user goals for the site. Remove features and content that are non-essential to these.
  • Use minimalist wireframes and prototypes first before visual design. If the layout isn’t simple in black and white, complexity will compound with visuals.
  • Limit font styles to one or two complementary options. Too many looks chaotic.
  • Use white space liberally around elements and text to reduce crowding. White space improves scanability.
  • Select a constrained color palette with one primary, one secondary and neutral shades. More breeds visual confusion.

Mobile-First Design

With growing mobile internet usage, a mobile-first strategy has become essential. Start by designing for mobile before expanding layouts to desktop. This reduces unnecessary elements and ensures mobile users can achieve key goals easily. Use responsive frameworks like Bootstrap to quickly optimize sites for all devices.

  • Start designing the information architecture and wireframes for mobile to reveal the absolute core elements.
  • Use responsive CSS frameworks like Bootstrap or Grid to build adaptable foundations making mobile to desktop expansion easier.
  • Design components to reflow naturally in narrower/wider contexts. Identify elements to show/hide/collapse/expand responsively.
  • Use relative units like %, vw, vh not fixed px sizes for most elements allowing greater fluidity cross-devices.
  • Test continuously on real mobile devices during development to fix issues early before expanding.

Clean Code Matters

Well-organized, valid code improves development efficiency, site performance and SEO. Validate HTML/CSS code with W3C tools. Use coding standards like HTML5 semantic structural elements. Organize files logically with comments for what’s not obvious. Modularize reusable code into functions/libraries. Keep code clean with linters like ESLint.

  • Create a logical information architecture with organized files and folders for HTML/CSS/JS code bases.
  • Use code linting tools like ESLint early to enforce syntax consistency and find bugs.
  • Validate all HTML frequently with the W3C Validator to ensure well-formed structure.
  • Adopt HTML5 semantic structural elements like header, section, article, footer for better document outlines.
  • Comment areas of CSS and JavaScript that are complex explaining the logic. Code should mostly speak for itself through clarity.
  • Modularize reusable code blocks into functions, mixins and libraries you can load anywhere needed.

User Testing and Data Analysis

No amount of planning guarantees users will interact with sites as intended. Thorough user testing reveals sticking points. Start early with quick paper prototype tests. Follow up with live site click/scroll heatmaps, A/B tests of alternative interfaces, analytical review of usage metrics. Observed user behavior beats assumptions and opinions for shaping improvements.

  • Conduct user testing early and often, not just before launch.
  • Start with simple paper prototype tests with a few users. Have them perform key tasks and note where they get stuck.
  • Create clickable design prototypes and observe real user behavior through services like UserTesting.com or Validately. Identify usability obstacles.
  • Use heat map tools like HotJar or CrazyEgg to see real mouse movements, clicks, scrolls. What catches attention and what goes ignored?
  • Implement A/B split tests for alternative interfaces, content wording, call-to-action options. Statistical significance indicates better performance.
  • Set up analytics platforms like Google Analytics before launch. Establish goals, events tracking, funnels.
  • Review site metrics to spot high bounce pages, understand user journeys, analyze funnel fall out. Apply learnings.

Accessible to All

Ensure inclusive sites that accommodate disabilities with good coding practices like ARIA roles for screen readers, color contrast minimums, keyboard shortcuts so sites work without mice. Support text resizing, heading hierarchy, alt text for images. Check accessibility with auditors like WAVE and whole user groups. Designing for extremes improves universal utility.

  • Semantic HTML provides underlying document structure for screen readers like JAWS to better interpret.
  • ARIA roles indicate landmarks like navigation, menus, tabs, alerts for assistive devices.
  • Strong visual color contrast ratios meet minimum standards for low vision users.
  • Keyboard shortcuts support motor disabilities allowing site use without a pointing device.
  • Ensure links, buttons and images have rich descriptive alt text if visuals don’t load.
  • Support text resizing, heading hierarchy, captioning for varied user needs.
  • Do formal accessibility reviews with services like WebAIM WAVE and recommendations from target advocacy groups

Performance Optimization

  • Minify CSS, JavaScript, HTML and image files to reduce site weight for faster loading.
  • Enable compression with tools like GZip to compact transferred resources.
  • Leverage browser and proxy caching through set expiration times to reduce repeat file transfers.
  • Establish performance budgets and use tools like Lighthouse to identify optimization opportunities.
  • Delay non-critical loading with deferred attributes to get pages visible faster.
  • Limit redirects which incur extra round trips. Set up efficient routes.

Security Best Practices

  • Establish TLS/SSL encryption for all sites to activate HTTPS and prevent snooping of traffic.
  • Enforce strict CORS policies for APIs to prevent unauthorized cross-origin requests.
  • Sanitize and validate all user-entered data server-side before processing to block XSS attacks.
  • Only give database user accounts necessary permissions to reduce exploit risks by hackers.
  • Implement reCAPTCHA protections against bots on signup flows and user input forms.
  • Schedule regular backups for both databases and file systems to support recovery needs.

Search Engine Optimization (SEO)

  • Optimize page titles and descriptions for compelling search previews driving clicks.
  • Provide XML site maps to support discovery of new and updated content pages.
  • Implement structured data markup schemas like JSON-LD to spotlight key data.
  • Produce metadata optimized blog articles driving relevant organic search traffic.
  • Monitor position tracking for key terms with tools like SEMRush to improve rankings.
  • Fix crawling errors revealed in Search Console to better index pages.

In summary, creating effective websites that meet diverse user needs requires following established best practices around simplicity, mobile-first design, clean code, testing and accessibility.

Adopting a simplicity mindset focused only on core site goals and tasks creates more seamless user experiences. This requires ruthless reduction of unnecessary elements through minimalist wireframing and visual design.

Mobile usage continues to expand globally so mobile-first and responsive techniques enable sites to adapt across all devices. Design initially for narrow mobile views before expanding layouts outwards on bigger screens.

Well-organized, valid HTML, CSS and JavaScript codebases improve findability, flexibility and optimization for years of iterative development. Modular programming and code linting encourage these quality coding principles.

The most direct way to build intuitive interfaces is watching real users interact with sites to reveal usability issues. This requires formal user testing modalities like click tracking heatmaps, A/B testing of alternatives and analytics funnel review.

Accounting for diverse user abilities through strong accessibility practices expands the reach of websites to more groups through adaptive techniques like semantic markup, keyboard shortcuts and screen reader ARIA landmarks.

Websites that master these core disciplines can function reliably for users and business goals while also supporting future growth through sustainable foundations. They require continued learning, testing and optimization but set digital experiences up for longevity rather than quick demise from preventable limitations. Mastering website best practices separates high-functioning digital presences from low-quality ones across metrics like customer satisfaction, sales conversion, organic search traffic and brand reputation.
