I've been tasked with helping the IT department of a large company make a case for keeping their regional website and simply re-branding over having their website absorbed into that of their parent company(located elsewhere in the world). The report I've written so far is for too long to ask everyone here to read, but I wanted to make sure that I'm not forgetting anything from an SEO standpoint. I'm also digging for numbers from a reputable source to back our claims.
I was wondering if anyone knows of a reputable source that has researched/published statistics on the benefits of a regional website from a SEO or general marketing standpoint?
