Not being picky for the sake of it, but you need to be sure the content of your website is spelled properly or people won't find you.

That's especially true if you pay for Adwords or similar - at least on pay per click you won't get a big bill for the typos but the object is to drive traffic to the site so you need to find phrases that someone coming to St Andrews to play golf might type in - like Edinburgh Airport to St. Andrews, etc.

I don't know if I would know to search for an "airport transfer", and "taxi" is just too generic.
