SEO-анализ сайта и рекомендации

Here is the evaluation of the website nonsf.ru from an SEO perspective, based on the provided HTML code:

**1. Page Title**: 8/10
The page title is descriptive and relevant to the content, but it's a bit long and may be truncated in search engine results pages (SERPs).

**2. Meta Description**: 7/10
The meta description is present, but it's a bit short and doesn't fully summarize the content of the page.

**3. Header Tags**: 9/10
The page uses header tags (H1, H2, etc.) to structure the content, which is good for accessibility and SEO.

**4. Content Quality**: 8/10
The content appears to be well-written and informative, but it's a bit lengthy and may benefit from breaking up into smaller sections.

**5. Image Optimization**: 6/10
Some images have alt tags, but not all of them. Additionally, image file names are not descriptive and do not include target keywords.

**6. Internal Linking**: 5/10
There are some internal links, but they are not descriptive and do not use anchor text that includes target keywords.

**7. Mobile-Friendliness**: 9/10
The page appears to be mobile-friendly, with a responsive design that adapts to different screen sizes.

**8. Page Speed**: N/A (cannot be evaluated based on HTML code alone)
Page speed is an important factor in SEO, but it requires additional tools to evaluate.

**9. Meta Keywords**: 0/10
Meta keywords are not used, which is not a problem since they are no longer a ranking factor.

**10. Structured Data**: 0/10
There is no structured data (e.g., schema.org) on the page, which can help search engines understand the content and provide additional information in SERPs.

**Recommendations:**

1. Optimize image file names and alt tags to include target keywords.
2. Improve internal linking by using descriptive anchor text that includes target keywords.
3. Break up long content into smaller sections and use header tags to structure the content.
4. Consider adding structured data (e.g., schema.org) to the page to provide additional information to search engines.
5. Review and optimize the meta description to better summarize the content of the page.
