It wouldnt matter if he did share the keywords, if he is ranking high for a populat keyword, it will be hard for you to push in quick anyway, least with 'white hat' SEO. Target something you are interested in, maybe movies, or games, you could do review or link to other websites that are selling the particular item you are talking about that day (such as amazon), something like that. Its easier doing something that suits you rather then trying to copy someone else just because they are making money of it right now.
I have a multi-topics site with reviews, but I thought of doing a copy of it but limiting categories to a high paying niche such as health for instance. Do you think it is worth it? Just creating it will mean i'll have two web properties instead of one.
Its worth it to start working towards a big keyword. It will take a long time but it will ultimately be worth it
You make it sound like its really hard? lol as long as you put constant work in to it, e.g get backlinks everyday ect. its pretty simple to climb up.
after a long search i also just found that SEO can give you good earnigns from Google Ad Sense as well!! ZOMG!! It really works!
Lol, if it's a technology blog, most often we'll be talking about news sites, therefore the keywords aren't static at all.
It's not about your keywords - its about your content and if its quality. Technology blogs always earn well with ad networks - because of the high paying amount of keywords.
