I have a wordpress website for my business and its success will be largely dependent on google ranking. The structure of the theme I'm using is designed for a blog, not for a business website. That means the source code is quite ugly-looking. My question is, does it affect SEO at all? I know that it can affect SEO somehow by the page taking longer than needed to load, but apart from that, will there be any penalizing for having a suboptimal or confusing html structure? Thanks
