SEO-анализ сайта и рекомендации

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

**1. Page Title**: 8/10
The title tag is present and descriptive, but it's not very attention-grabbing and doesn't include 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 and entice users to click through from search engine results.

**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 engaging. 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 understand the website's structure and crawlability.

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

**9. Page Speed**: 6/10
The page loads relatively quickly, but there's no optimization of images, CSS, or JavaScript files, which could improve page load times.

**10. SSL and Security**: 10/10
The page is served over HTTPS, which ensures a secure connection and is a ranking signal.

**Recommendations for improvement:**

1. Add a meta description tag to provide a summary of the page's content.
2. Implement header tags (H1-H6) to structure the page's content and improve readability.
3. Create high-quality, engaging, and unique content that targets specific keywords.
4. Optimize images by compressing them and using lazy loading.
5. Add internal links to help search engines understand the website's structure and crawlability.
