Do a SEO analysis for keywords

Hello, I would like to start a blog with a precise content in order to generate revenue (CPC, Adsense, etc...). For this content, there are of course associated keywords. I would like to know if there are other people who are already doing this kind of blog (with the same content), where they rank on google searches, how many visitors they get. I would also like to know how many people in general are looking for all these key words, and other words associated by google. Finally, I would like to know if having these words in the website name would have a good impact, and I would like you to propose the most optimized website name that would get me on top of google searches for these keywords related to my content. Detail : the website will be in french, and so the keywords are also in French. Though you don't necessarily have to speak the langage for this kind of task I guess ? It's up to you to tell me. Thank you for your time. Waiting to hear from you soon, Kent
