Hi, I am a web developper, passionated in IT and want to open a blog of text-images-videos tutorial and help about IT topics like Windows, Graphism and Music (How-to's, comparisons between softwares or companies, etc...). I am french and I see that there's competitors in the business from a long time-ago. But I think that most of them aren't offering good tutorials for beginners and that's what people really needs. And, advanced tips and tricks too, surely ! Monetization would be by affiliate programs (buy hardware or softwares) and ads. But this is not the question. Does long-tailed keywords can be a huge thing for this ? Because all popular threads have been done and I will take some times to get on 1st page of results for those, I think. The Competitor's domain authority are pretty high, but they don't cover all subjects as I would like to do. I think that this kind of site can be easily shared on the web considering the 'helping' topic, which is good to drive traffic first months. What I am asking here is, do you think this could be a good niche ? Is it too 'large' and should focus more ? I want to SEO this very well ! Thanks a lot.
