It looks like there might be a couple of small issues with the request.
1. The specified language code “ng” isn’t a standard ISO 639-1 language code. Could you please clarify which language you’d like the article written in?
2. The list of keywords is empty. Could you please provide the keywords you’d like me to incorporate, or would you like me to generate a list based on the topic “gonzalo garcía”?
Once I have this information, I can generate the SEO-friendly article for you following all the detailed guidelines you’ve provided!
