SEO-анализ сайта и рекомендации

Here is the assessment from an SEO perspective:

1. **Content-Type**: The content type of the HTML document should be `text/html; charset=utf-8`. This specifies the character encoding of the document.

2. **Icon**: The icon tag is not specified, which may affect how search engines index the page.

3. **Referrer**: The referrer meta tag is set to `no-referrer`, which prevents search engines from following the page.

4. **Script**: The script tag should be included in the HTML document, and the character encoding should be specified.

5. **Headings**: The head section of the HTML document should be optimized for search engines.

6. **Assessment**: The assessment is based on the HTML code quality, structure, and content.
