1. Semantic HTML: Use semantic HTML elements to structure your content. This not only improves the organization of your content but also helps screen readers understand the purpose of different sections. Examples of semantic elements include <header>, <nav>, <main>, <article>, <section>, <aside>, and <footer>.

2. Clear and Descriptive Labels: Provide clear and descriptive labels for form elements using the <label> element. This helps screen reader users understand the purpose of each form field and provides context. Also, ensure that the for attribute in the <label> tag matches the id attribute of the associated form element.

3. Meaningful Links: Avoid generic link text like "click here" or "read more." Instead, use descriptive link text that conveys the purpose or destination of the link. Screen reader users often navigate by a list of links, so meaningful link text is crucial for them to understand the content.

4. Alternative Text for Images: Always provide alternative text (alt text) for images using the alt attribute. The alt text should describe the content or function of the image. For purely decorative images, use empty alt text (alt="") to indicate that the image is not conveying important information.

5. Headings and Structure: Use proper heading tags (<h1>, <h2>, etc.) to create a hierarchical structure for your content. Headings help screen reader users navigate through your content and understand its organization. Make sure to use headings in sequential order.

6. ARIA Roles and Attributes: ARIA (Accessible Rich Internet Applications) roles and attributes can be used to enhance the accessibility of complex elements that are not adequately conveyed through standard HTML. However, use ARIA sparingly and only when necessary, as incorrect usage can lead to confusion.

7. Skip Navigation Links: Include a "skip to main content" link at the beginning of your page. This allows screen reader users to bypass repetitive navigation links and quickly access the main content of the page.

8. Avoid Tables for Layout: Avoid using tables for layout purposes. If you need to present tabular data, use the <table> element with appropriate header cells (<th>) and data cells (<td>), and associate headers with data cells using the scope attribute or <th>'s id and <td>'s headers attributes.

9. Keyboard Navigation: Ensure that all interactive elements can be navigated and activated using the keyboard alone. This is not only important for screen reader users but also for people with mobility impairments who rely on keyboard navigation.

10. Testing with Screen Readers: Regularly test your web pages with popular screen readers like JAWS, NVDA, and VoiceOver to ensure that your markup is working as intended and providing a good user experience.

Remember that making your website accessible is an ongoing process. Keep up with the latest accessibility guidelines and standards, and be open to user feedback to continuously improve the accessibility of your web content.
