Another good option for danish expansion is to not go south, but to instead do what your viking ancestors did - go west. Divide your beginning forces into two - one taking Stockholm and Olso (converting Olso to a city), the other taking Hamburg. Don't expand south further than Hamburg. Build your economy and a navy in Arhus, Stockholm and Olso, and your landforces in Hamburg. Make a sizeable army consisting of plenty of viking raiders or dismounted huscarles, but them on a boat and send them west. If you're quick enough the scots won't have taken the castle at Inverness, which makes a good staging area for your campaign against the Scots and English. Taking Britian means you'll have TWO strong, easily defended economic bases for further conquests.
Expanding southwards will get you quickly involved in continental european politics, and you'll take over the HREs position as being surrounded by enemies and fighting a multi-front war. I tried it in a campaign I'm playing now, and I'm now at war with the HRE, Milan, Polan, Russia and Hungary (and of course Egypt and the Mongols in the Holy Land).
