SEO-анализ сайта и рекомендации

Sure, I'd be happy to evaluate the SEO of the website <http://5islands.ru/> based on the provided source code. Here are my evaluations for various SEO parameters:

1. Meta title: The website has a unique and descriptive meta title tag, which is a good practice. However, the title is a bit long and could be optimized for better click-through rates. Score: 8/10.
2. Meta description: The website has a unique and descriptive meta description tag, which is a good practice. However, the description is a bit short and could be optimized for better click-through rates. Score: 7/10.
3. Heading structure: The website has a proper heading structure, with one H1 tag and several H2 and H3 tags. This is a good practice for both users and search engines. Score: 9/10.
4. Keyword usage: The website has a good balance of keywords, with the main keyword "острова" (islands) appearing several times in the content. However, the keyword density could be optimized for better search engine visibility. Score: 7/10.
5. Image optimization: The website has several images, but none of them have alt tags or descriptive filenames. This is a missed opportunity for search engine visibility and accessibility. Score: 5/10.
6. Mobile optimization: The website is not optimized for mobile devices, which is a negative factor for search engine rankings and user experience. Score: 4/10.
