this is a question ?
Some WordPress themes are designed to accommodate blogs and some are designed for full-blown websites. While you can take a theme designed for a website with a blog and convert it into a blog only site, it is difficult to do the opposite. Expecting that you can convert a blog theme into a professional company website is a step towards disappointment. If you need a theme for a website, then search for WordPress themes that specifically say they are for business, corporate use, or a CMS.
Does the theme support basic wordpress functions?
You may think I’m crazy for even bringing this up, but there is a reason. The “glass half full” kind of girl that I am always thought all themes supported core WordPress features. The truth is that this is an incorrect assumption. I have an SEO client I am working with right now that has a theme so poorly coded it is killing me. It lacks basic elements like proper spacing, ordered bullets, featured images for posts, commenting, and on and on. The creator of the theme just doesn’t know WordPress as much as he should. I don’t think he intentionally left these items out, but they are in fact missing. Prior to buying any premium WordPress theme, make sure the theme supports core features like: WordPress menus, widgets, multiple sidebars, featured images, blog page beyond that of the home page, individual posts, author boxes, commenting, 404 page, sitemaps, etc.
