There are many ways to write a blog in two languages, but the most important thing is to find a style that works for you. If you want to write in English, use an informal tone and focus on storytelling.
On the other hand, if you want to write in your native language, use a more formal tone and focus on technical information.
Another important factor is to make sure your blog content is easy to understand. Always use clear and concise language, and avoid using jargon or technical terms unless you are specifically explaining them.
Also, make sure your content is well-organized and easy to read.
Finally, remember to keep your blog updated regularly with new content. This will help attract more readers, who will then become advocates for your blog and help promote it online.
