making sure a site has been SEOed

Hi,
Has any SEO work been done on http://www.mangusfinance.com/? I'm considering putting smart crawl on this site? It has SEOPressor on it but I don't see SEO work done. Just want to make sure i'm not missing anything. I just have been hired to manage this site and don't want to have to do a lot of duplicate work if its already been SEOed.
