I have my business website - I am a web designer and developer, and also buy/sell websites/domain names.

As such my website links to 'Our sites' => the websites which we design and run as well as a variety of tools such as a domain whois tool. These are obviously relevant to the business.

As an individual, I like to travel and do white water kayaking as a hobby. I also have a degree in economics. I have thus created a blog on my business website where I write about domain names, web design, kayaking, travelling and economics.

I've just begun researching SEO and am looking into optimizing my business website. I don't actually directly offer any services to clients at the moment, my main aim is to have a business website which supports my websites.

If for example a potential advertise on one of my sites checks out the business website, I want them to think professional, down to earth, quirky.

Given this is having my business/personal interests intertwined a problem? For SEO.. on my homepage for example when I'm writing a headline and a paragraph about what we do.. what do I put? and how do I optimize for SEO with keywords and the like?

Further to the above, my company sponsors me and a group of accquantances as a kayaking team.. as such my personal interests do sort of overlap (just to add a complexity :))
