Getting your URL with a # sign indexed in SEO can be tricky due to the way search engines read these symbols. The # sign is often seen as a fragment identifier and not typically indexed. However, there's a workaround using the "!" sign after the hash to create "hashbangs", which are more SEO-friendly. Remember to properly structure your URLs and ensure they're pointing to unique and relevant content. It's also essential to keep your sitemap updated, which helps search engines better understand and index your site.
