what you don't realize since you are just starting is that Apple just changed the search results to weight time on store and number of downloads more heavily. That means your SEO isn't going to put you in the front right away. this change is going to have the effect of less total apps seen which is going to make it even harder for new apps. I just had an app that got covered by several major blogs, good reviews, and had hundreds of downloads for the first few days. After a month I'm now getting between 0-2 downloads a day, and I'm 8 for the search of my app name.
