I think everyone gets discouraged at times. I know I do and I've been at this a long time.

I looked at your website. I really like the design! Your About Me page should be stronger. I suggest you find your competitor websites and look how they have done their About pages.

Try using spyfu.com to check on your competitors based on your keywords. semrush.com is another tool to checkout. It's free to check your domain name.

I don't know how much traffic you are getting. But I suggest you add much more content. I didn't find many links to products. I found one for protein whey. The book reviews should include links to Amazon. I also think a number of the images should be upgraded. Some were fuzzy.
Hope this helps.

Don't feel bad, I have been here a year and still building my site. I work on it every day but still no sales. I'm not giving up, I know it will come soon.
I just took a look at your site and it will not let me scroll down. When I start to scroll it takes me back to the header. You may want to check into that.

I don't want to discourage you, but some people go a year or longer without a sale... That's why the absolute hardest part of it is having the determination to continue. It will come in time. You just need to hang on until then.

I've been here for 11 months and I haven't made a dime from WA yet. I've only made a few dollars with Adsense. I'm wondering where I am going wrong too....but I'm still here.
