Relevant Design Trends and Best Practices

Design trends come and go rapidly, so it's crucial to understand what works in 2025. Here are some of the most relevant current best practices:

Mobile-First Design

Mobile traffic now accounts for over half of all website visits[1]. A mobile-first design approach optimized for smartphones is essential.

• Use a responsive layout with flexible images and text
• Design for fat thumbs - make buttons and links large enough to tap easily
• Limit horizontal scrolling, anchor CTAs in place as the page scrolls

Accessible and Inclusive Design

Your website should be usable for all people. Follow standards like WCAG 2.1 for accessibility.

• Add ARIA attributes for screen readers
• Use proper heading structure and alt text
• Design for people with visual, motor, or cognitive disabilities

Performance and Speed

Site speed greatly impacts conversions and SEO. Test regularly and optimize.

• Minify HTML, CSS, and JavaScript
• Compress images and videos
• Use a CDN to distribute resources

Bold, Vibrant Design

Maximalist, upbeat designs perform well by grabbing attention.

• Use striking colors, bold fonts, and immersive imagery
• Incorporate engaging animations and illustrations
• Balance vibrancy with usability - don't overwhelm

Optimizing Site Architecture and Navigation

Your website's information architecture and navigation hugely impact usability and conversions. Here are proven tips for structuring your site effectively.

Clear, Consistent Navigation

Make it easy for visitors to find what they need.

• Use a fixed header with persistent navigation
• Limit primary nav links to 4-7 core pages
• Include contextual secondary navigation as needed

Intuitive Page Layouts

Guide visitors to take desired actions using visual hierarchy and gestalt principles like closure and continuation.

• Visually emphasize calls-to-action
• Use negative space purposefully to direct the eye
• Chunk and align related elements

Logical Information Flow

Structure pages and content for progressive disclosure and clear next steps.

• Lead with the most critical information
• Make paths forward obvious through design
• Use whitespace and dividers to separate sections

Crafting Engaging, Persuasive Content

Your website copy has immense power to capture attention, build trust, and move visitors to convert. Here's how to create content that sells.

Direct, Concise Language

Get to the point quickly and avoid fluff.

• Lead with the value proposition and benefits
• Use short sentences and paragraphs
• Cut unnecessary adjectives and filler words

Active Voice and Direct Address

Speak directly to the reader to boost engagement.

• Use "you" frequently
• Write in active voice with strong verbs
• Avoid passive voice and clinical language

Relevance and Personalization

Connect with the visitor's needs and perspective.

• Know your target personas intimately
• Use their language and talk about their goals
• Personalize content with dynamic fields when possible

Optimizing for Conversions With Calls-to-Action

Calls-to-action (CTAs) prompt visitors to take desired actions. Follow these best practices to maximize conversions.

Strategic Placement of CTAs

Put CTAs where people are primed to click.

• End of blog posts or key content sections
• Next to supporting images/videos
• Within sidebars for secondary actions

Clear, Action-Driven Language

Use strong verbs that push visitors to act.

• "Get started now" not just "Learn more"
• "Add to cart" not just "Buy now"
• "Download" not just "See attachments"

High Visual Prominence

Make CTAs stand out on the page through design contrast.

• Use unique, high-contrast colors
• Increase size relative to body text
• Use negative space and borders to isolate
