Well this isn't a very clear cut issue for the simple fact that there's no full record of the location of every Norse raid or spot where every Norse trader set up shop.

Now obviously Norse interactions were more common in certain areas over others, the most famous examples being the Norse invasions/raids on England (and the rest of the British Isles), the establishment of the Kievan Rus in Russia/Ukraine, and the formation of Normandy. However without far more detailed records than currently available it is impossible to know exactly if raiders or traders were more frequent sights in certain parts of the Norse influenced world.

In general Norse activity was economic in purpose, the difference between a trading expedition through Finland and into the Byzantine Empire or the Islamic World isn't really all that different from a raid on England. Both are fundamentally economic exercises, one just involves fewer axes in skulls. Indeed there isn't a great deal of separation between the two in the few sources that are available. While I am loathe to rely on the sagas, there are interesting examples of how trading expeditions (such as seen in the two sagas that make up the "Vinland Sagas") were endeavors that were quite seriously undertaken. Obviously there is going to be some difference from reality when examining these fictional scenarios, but the fact that viking expeditions ranged as far as modern Canada shows that the search for raw materials was every bit as motivating as the desire to loot and plunder.

This bears true in other parts of the Norse world as well.

Peter Heather argues in Empires and Barbarians that Norse development of Rus society in Russia was predicated on trade routes and connections that pre-dated Norse involvement. However Norse involvement brought a new scale of activity to the area and allowed for the coalescence of various states. Using goods in Finland, namely furs and timber, the Norse and their intermediaries were able to trade for silver and other luxury goods in the Islamic and Byzantine worlds. However there were also raids and other attacks on the Byzantine world, famously by the Kievan Rus resulting in the creation of the Varangian guard, as well as subsequent conflicts such as the wars between the Kievan Rus and their allies and John I of Byzantium.

I go into more detail about the economic nature of Norse activity in this answer

Its impossible to really tell if raiding or trade was more prevalent in Norse interactions with many areas, but the two were not incompatible.
