It looks like you did most of what you typically would do for SEO purposes. You can check out what you can do better here:
http://www.woorank.com/ Top priorities for your website:
Few things woorank recommends:
-Promote your website on Social Media
-Write more content
-Set a name for all your images
-Optimize your website for Mobile browsing
-Check the title of your website
Other things I would recommend from my understanding:
- Only list about 10 keywords to many is just a waste. Spread the rest of the keywords on other pages but keep it to 10 on each page.
- You Keywords in your Page Title you can use Keep Slim in it but.... The search engines are already going to find Keep Slim by just the Web address so technically you can use that space for "Key" keywords.
- You need to have information on the page that relates to your keywords page title H1 H2 tags that help make your page relevant.
- Naming your Images is huge to because it will make your site that much more relevant and that is what SEO is about, is your site really what you say it is.
Good Luck, I hope this helps in some way.
