✅ 1. Mobile Responsiveness
Most web traffic in 2025 comes from mobile—your site needs to look and work flawlessly across all devices.
- Use responsive design for seamless adaptation
- Test with Google’s Mobile-Friendly Tool
- Optimize mobile load times and button spacing
We'll preview your site's mobile layout during your free demo.

Page speed impacts SEO and bounce rate. Google penalizes slow-loading sites.
- Test with PageSpeed Insights and GTmetrix
- Enable compression (e.g., Brotli or Gzip)
- Minimize HTTP requests
- Leverage browser caching
We’ll show your current speed score and how fast your site could be.
✅ 3. Clean URL Structure
SEO-friendly URLs help both users and search engines.
- Include relevant keywords
- Use hyphens (not underscores)
- Keep URLs short and readable
Your free demo site will include optimized URLs that align with Google’s best practices.
✅ 4. XML Sitemap
Search engines rely on sitemaps to understand your site’s structure.
- Submit your sitemap to Google Search Console
- Ensure it includes all key pages
- Monitor for crawl errors or warnings
We’ll build and submit your sitemap during onboarding.
✅ 5. Robots.txt File
Control what search engines can and can’t index.
- Avoid accidentally blocking key pages
- Check regularly for disallow errors
- Use robots.txt in tandem with your sitemap
We’ll show you how your robots.txt is currently configured—and fix issues if needed.
✅ 6. Canonical URLs
Avoid duplicate content by clearly specifying the preferred version of each page.
- Use <link rel="canonical"> tags
- Make sure every page has a unique canonical
- Prevent SEO dilution and indexing confusion
Our builds automatically assign proper canonical tags to every page.
✅ 7. HTTPS & SSL
Security affects trust—and SEO rankings.
- Install an SSL certificate (we provide one with every site)
- Redirect all HTTP traffic to HTTPS
- Update internal links to reflect the secure version
Your demo will reflect a fully secure, HTTPS-enabled site.
✅ 8. Structured Data (Schema Markup)
Help search engines understand your content and earn rich snippets.
- Implement schema.org markup for local business, services, products, reviews, etc.
- Test with Google's Rich Results Test
- Improve click-through rates in search
We’ll show live examples of schema markup on your demo site.
✅ 9. Accessibility Enhancements
A more accessible site helps real users—and gives you an edge in SEO.
- Add alt tags for all images
- Ensure color contrast ratios meet WCAG guidelines
- Use screen reader-friendly code
- Test with tools like WAVE
Your demo will show how we build accessibility into every design.
✅ 10. SEO-Friendly Site Architecture
A strong site structure helps bots crawl effectively and users navigate effortlessly.
