1. Clear and intuitive navigation: Make sure users can easily find and navigate to different sections of your website.
2. Simple and consistent layout: Use a clean and organized design that is consistent across all pages to provide a seamless user experience.
3. Fast loading times: Optimize your website's performance by minimizing page load times. Compress images, remove unnecessary scripts, and use caching techniques.
4. Mobile responsiveness: Ensure that your website is fully optimized for mobile devices and offers a seamless experience on different screen sizes.
5. Good error handling and feedback: Display clear error messages and provide helpful feedback to users when they encounter errors or invalid inputs.

Accessibility:

1. Proper use of HTML markup: Use semantic HTML elements appropriately to assist users with disabilities in understanding the website structure.
2. Alt tags for images: Provide alternative text descriptions for images to assist users who cannot visually view them.
3. Descriptive link texts: Use informative and descriptive text for hyperlinks to aid users in understanding the destination of the link.
4. Sufficient color contrast: Ensure that text and important elements have sufficient contrast with the background to make them readable for users with visual impairments.
5. Keyboard accessibility: Ensure that all functionality can be operated using only a keyboard, as some users may not be able to use a mouse or touch input.

SEO:

1. Relevant and unique page titles and descriptions: Optimize each page's meta title and description to accurately describe its content and improve search engine visibility.
2. Use of header tags (H1, H2, etc.): Organize your content using header tags to provide structure and guide search engines in understanding the hierarchy of the information presented.
3. Quality content with relevant keywords: Create unique and valuable content that aligns with user search intent and strategically incorporate relevant keywords.
4. Good internal linking structure: Use internal links throughout your website to help search engines discover and navigate between different pages.
5. Sitemap and robots.txt files: Create and submit a sitemap to search engines to ensure all website pages are indexed, and use a robots.txt file to control access to certain pages.
