I'm a newbie in adsense. I want to build a blog about iPhone/Apple because I like this niche. I hope my blog can be exist for several years. I can write a good article manually about this, but I also expect its adsense ads has high paying for me later. Actually I'm not good to find keywords which has high paying ads.
Please give me your opinion about this niche. I very appreciate if you also tell me how to find high paying keywords for ads of iPhone/Apple niche.
Thank you guys
