Please have a look on this page of my site: http://wpmix.com/design-services/ and let me know if I have optimized it well for these 2 keywords: custom Wordpress themes Wordpress designer I'm especially concerned if the keywords density ratio on my website is OK. Thanks in advance.
Looks like your site is not optimized for "Wordpress designer" Include this on your title and content too just like the first keyword you did. Other than that, change your page title from "design services" to one of the keyword that you think is most important. Basically, that's all you need for now.
