You need to stop submitting to different places! This is a time waster!
Focus on your blog - make sure the entire blog is around one central theme (or niche). Write, write, write.
Tags are SO easy. Under your posting area, before you publish, you will see a rectangle box where you can put your tags. All tags are, is simply words that people might search in order to find what you have on your blog.
For example, tags on your site might be "bux, bux.to, make money online, how to make money online, easy ways to make money online, fast cash on the internet..."
You should really check out the "Bum Marketing Method". He will explain exactly how to get FREE traffic to your site, AND be listed on the first page of Google. It works. It has worked for me several times.
Write some articles also and post them on www.ezinearticles.com and www.goarticles.com. Do some offline advertising as well. You know, car magnets, business cards, flyers... those are just the basic things. GET CREATIVE!
By the way, let me ask you this... do you LOVE what you are writing about? If you don't, scratch it and follow something you love.
