yes, fire your seo, coz he knows nothing about it – as someone said earlier, your site is making even the very basic seo errors.
main points,
i still get the securtiy issue
each page should have a unique title and meta description
your current title is crap anyways as there no real keywords in there apart from “online casino” which you will never rank high for.
your H1 tag title on homepage is crap – this should contain your targeted keywords
