To make a Silverlight page crawlable by search engines, you need to implement a mechanism that dynamically generates static HTML content that is equivalent to the Silverlight content. This can be achieved in several ways:
- Use server-side HTML generation: You can write a server-side script that generates an HTML representation of your Silverlight content, and serve this HTML to search engines.
- Use a dynamic HTML snapshot: You can use a tool like PhantomJS to generate a dynamic HTML snapshot of your Silverlight page, and serve this snapshot to search engines.
- Use Search Engine Optimization (SEO) techniques: You can use SEO techniques such as meta tags, descriptive URLs, and descriptive page titles to make your Silverlight content more discoverable by search engines.
In addition, it's important to ensure that your Silverlight page is accessible to users who do not have Silverlight installed, as search engines may not be able to crawl content that requires a proprietary plugin.
