I am trying to improve the SEO of a website. I notice the website itself is very cluttered and the content isn't laid out very well. The owner claimed it used to rank higher on Google, and that there are many positive reviews for the business (e.g. through Yelp) yet less popular businesses in the same area rank higher in search result. The cms is Yola. Can lack of following UI style guidelines affect search results?
I'm a bit new to SEO, and even though I've red up on it, I'm having trouble here. There's many things that could affect SEO so do you need to check each one individually or is there a technique to find what exactly is the problem?
