How to make an iframe seo friendly?

@dana 

1. Use relevant content: Make sure the content within the iframe is relevant to the overall page content. This will help search engines understand the context of the iframe and index it properly.
2. Optimize the iframe attributes: Use title, alt, and description attributes within the iframe to provide additional information to search engines about the content within.
3. Use a descriptive src attribute: The src attribute of the iframe should contain a descriptive URL that includes keywords related to the content within the iframe. This will help search engines index the content properly.
4. Use structured data: Include structured data within the iframe to provide more information to search engines about the content, such as author information, publication date, and more.
5. Avoid using iframes for important content: While iframes can be useful for embedding external content, avoid using them for important content that you want to be indexed by search engines. Instead, consider other options such as embedding the content directly within the page.
6. Test for accessibility: Make sure the content within the iframe is accessible to users with disabilities, as this can also impact SEO. Ensure that the content can be accessed and navigated easily by all users.
7. Monitor performance: Keep track of the performance of the iframe content in search engine results and make adjustments as needed to improve visibility and rankings.
