It's all about building up the popularity and branding of your site. If you continue to build your traffic and content, you'll continually gain a more popular blog over time. Once you think you're getting enough daily UV's and pageviews, consider selling ad space or working with a PPC/CPM network. There's tons of ways to make money with a blog, you just need to have the blog first.
What I've also seen is the trend with people using their website to promote direct selling or ebay items. That would certainly help to translate to higher earning especially if it's a hot item.
I think creating reviews as well as selling banners and ads for your site is one way to monetized your site plus adsense as well ..I havent tried promote affiliate products but I am interested in trying it out
Their are so many ways in earning in blogs you can write articles or perhaps you can have adsense and do affiliate
Well i think most people earn money with ad sense or other PPC services.Affiliates are also quite popular,but you could also try selling links
But no matter what you do with your blog,one thing remains the same...you need a popular blog with a lot of traffic
