SEO-анализ сайта и рекомендации

Here's an SEO evaluation of the website zabcenter.ru based on the provided HTML code:

**1. Page Title**: 8/10
The title tag is present and descriptive, but it's not very unique and doesn't contain the main keyword.

**2. Meta Description**: 0/10
No meta description tag is present, which is a missed opportunity to provide a summary of the page's content.

**3. Header Tags**: 6/10
There are no H1-H6 header tags used on the page, which makes it difficult for search engines to understand the page's structure and content hierarchy.

**4. Content Quality and Uniqueness**: 4/10
The content is minimal and not very informative. It's also not unique, as it's a generic "website under construction" message.

**5. Keyword Usage**: 2/10
There are no targeted keywords used on the page, which makes it difficult for search engines to understand the page's topic and relevance.

**6. Image Optimization**: 8/10
The SVG image is properly optimized with a descriptive title and alt text, but there's no image compression or lazy loading implemented.

**7. Internal Linking**: 0/10
There are no internal links on the page, which makes it difficult for search engines to crawl and understand the website's structure.

**8. Mobile-Friendliness**: 8/10
The page is responsive and adapts to different screen sizes, but there's no explicit mobile-friendly meta tag.

The page loads relatively quickly, but there's no optimization for page speed, such as code minification, compression, or caching.

**10. SSL and Security**: 10/10
The page is served over HTTPS, which is essential for security and trust.

**Recommendations for improvement:**
