1. Ignoring Mobile Users

The Mistake: Your website looks amazing on desktop but falls apart on mobile.
The Fix: Always design with a mobile-first approach. Use responsive design frameworks like Bootstrap or Tailwind CSS, and test your site on multiple devices. This Strategy was used for my portfolio Website Haya Asif

2. Overloading Your Website

The Mistake: Adding too many features, plugins, or animations that slow your site down.
The Fix: Keep it simple. Focus on what your users actually need. If a feature doesn’t add value, ditch it.

3. Skipping SEO Basics

The Mistake: Building a beautiful website that no one can find.
The Fix: Start with the basics—optimize your meta tags, use descriptive alt text for images, and create quality content. SEO doesn’t have to be complicated!

5. Not Using Version Control

The Mistake: Making changes directly on your live site without a backup.
The Fix: Use Git for version control. Platforms like GitHub or GitLab make it easy to track changes and collaborate with others.

6. Ignoring Website Security

The Mistake: Assuming your site is too small to be hacked.
The Fix: Always use HTTPS, keep your software updated, and consider adding a Web Application Firewall (WAF). Better safe than sorry!

7. Skipping Browser Testing

The Mistake: Assuming your site works perfectly on all browsers.
The Fix: Test your site on multiple browsers (Chrome, Firefox, Safari, Edge) and devices. Tools like BrowserStack can save you a lot of headaches.

8. Overlooking Accessibility

The Mistake: Building a site that’s not usable for everyone.
The Fix: Follow Web Content Accessibility Guidelines (WCAG). Use semantic HTML, add ARIA labels, and ensure your site is navigable with a keyboard.

9. Not Planning for Scalability

The Mistake: Building a site that can’t handle growth.
The Fix: Plan for scalability from the start. Use a robust hosting provider, optimize your database, and consider using a Content Delivery Network (CDN).Struggling with responsive design?

10. Ignoring User Feedback

The Mistake: Building a site without listening to your users.
The Fix: Regularly collect and analyze user feedback. Tools like Hotjar or Google Analytics can help you understand how users interact with your site.
