since i read so much information giving by DP members, i get a conclusion that CONTENT is very important to a blog.. so i get an idea, can i earning by adsense by create a blog just only have QUALITY CONTENT but nothing at all .. ? the niche will be HPK , will the adsense give me high paying per click by this way ?!?
quality content is the key. however, if you dont promote your site, no one will know about your content. you need to promote your site to drive visitors.
depends on the competition. If there isn't much competition for the keywords you are targetting, just putting them in the title will get you indexed in the first page and get traffic and adsense revenue. If however, there is a lot of competition, you will have to try link building etc.
What is this nothing else you're talking about? If you have quality content on a blog, what is missing?
Definitely your should have quality content...try to make use of that to increase your traffic..do some SEO..
You want to have great content optimized for keywords you can dominate, as well as lots of backlinks from high ranking authority sites to drive traffic to your site.
