Hi Jordan
Thank you for your response. That's interesting to know about the importance of site speed. Is there any reason why an SEO worth his/her salt should not be able to work with any sort of platform which the website has been built through? Does having a platform outside of Wordpress for example create big limitations for the vast majority of SEO consultants to do their work efficiently and make the relevant changes?
I'm potentially looking at finding another consultant as the Wordpress site which has been created by the current consultant does not IMO look as near as sharp as the site my friend developed. My friend didn't use a website builder, he created it himself. He just used a code template to make it faster and although he can code in PHP chose not to go with Wordpress as it wasn't as customisable.
Any advice you can provide would be super helpful right now. I'm in a proper quandary!
