1. Hire a professional graphic designer or group to do your logo, cards, and website. Amateur websites such as yours come off as cheap and unprofessional. So how on earth could I trust you to make a good product? If you're serious about doing business then the investment to hire professionals is worth it. Otherwise it'll never go anyway.
2. As previously mentioned, photography. A product shown in a poor light will be recieved as such. Again, if you can't manage it hire someone who can.
3. You don't accept credit cards? That's probably 99% of your lost sales right there. Find a portable credit card plan. Talk to your bank. Search the web. Use something like Intuit's GoPayment. There is zero reason not to accept CCs. Also keep an eye out for the best shipping options for your customers. That's something that's constantly ongoing. I can't tell you how many US websites have lost business from me because they're too lazy to provide me with options in shipping or to source out better rates. The people that do are the ones that get my business.
4. Your ingredients are larger than the copy for your products. Fact is you're not actually "selling" anything. You're just displaying some products and hope people will buy them. Advertising is "selling". It's not taking orders. Hit the library, get some books on sales/advertising/marketing and learn. ----, watch Mad Men.
5. Forget search engine optimization and all that crap. What drives sales is word of mouth, always. That means hitting farmers markets, craft fairs, malls, etc. everywhere and anywhere ALL the time. Meet and greet, press the flesh, give out samples and business cards, network. As you start to build a loyal base, they'll tell two friends, and so on, and so on, and so on.
Most of all you really have to want to succeed. You have to be really driven to take it to the next level. If you're not then you'll remain a hobbyist. And there's nothing wrong with that. Lots of people want to be successful but lack the drive and ambition for it and that is paramount. Wishing for it won't make it happen.
Even with the points I've given you there's a ton more to do. Sit down, make a plan, put it all on paper, set schedules and goals. If you can't even commit to that much then once more stick with it as a hobby and figure out something else you can be really passionate about if you want full-time self-employment.
I hope none of that came off as mean, because it's not my intent. My intent is to provide you with some cold hard facts as well as get you to take a long hard look in the mirror and see if this is what you really want to do. It's a long hard slough. Doesn't mean it can't be rewarding and fun, but self-employment really isn't for most people.
