Hey Isabel. I would definitely create your blog in your native language if that is the one that you write better in. If your English grammar isn’t impeccable, you will have a hard time getting a loyal audience of English speakers. A blog written in English has the potential for a larger audience, but a blog in your native language will have less competition and the potential for a far more LOYAL audience. I hope that helps!
Once you setup your account on AdSense you will be given a code to add to your blog. This code will automatically display advertisements on your blog from companies who are part of Google’s advertising network. You may see ads from small companies related to your topic, or you may see ads from large companies that are completely unrelated to your topic.
NOTE: I’ll get into this in the section on Helping Other Bloggers, but be sincere in your help. If you only seek out to get something out of someone else, you won’t form a relationship with that person. I’ve liked Stephanie’s blog and content since I first saw it. She has an amazing story of being broke in New York City, and she’s built this amazing personal finance business in just a couple years. I help Stephanie because I like Stephanie, not because I want or expect to get anything out of the relationship.
This is the strategy that most bloggers start with when looking to monetize their blog. However, keep in mind you're not limited to selling banner ad spots (which is generally an ineffective strategy these days). Consider other areas you could rent out: space on your pop-up box, social media headers, the "P.S." on your email newsletters...think outside the box (quite literally).
The truth is, it's not as easy to carve out your space on the web and make a name for yourself as a blogger today, as it was back when blogging was brand new. And it takes a lot of time to build your audience to the point where it's successful. (The most successful, multi-million dollar blogs today were started around 2005 or earlier.) So it's definitely not something you can get rich quickly with, though many people do work on their blogs full time.
Notice that I avoided putting a specific dollar figure on the amount you can make from blogging. It will come down to your work ethic, your skills as a writer, your ability to generate targeted traffic, and plain old good luck. It’s a bit like baseball: everyone played it as a kid, only a small fraction make it to college ball, an even smaller number become professional, but only the cream of the crop makes it to the majors.
Make it easy for readers to browse – If you want more pageviews, you should make it as easy as possible for readers to read your other blog posts. You will want to make it easy for readers to find your blog homepage, categories, tags, search bar, and so on. Also, I recommend including links in every single one of your blog posts, so readers can easily find related topics.
