You don't see too much of Olaf in the jungle anymore, but I feel that champs like Olaf simply cannot match up to the trinity of bruiser jungle champs: Vi, Jarvan IV and Xin Zhao. Especially with these three champions building great support items like Locket of the Iron Solari and sometimes even a Randuin's Omen. They're great champs that fit well into almost any composition and still deal TONS of damage. Plus, helping the support save some gold for extra items is always a good thing.

Good name. However, I don't really like the Scaling Health Seals, especially if you don't use Atma's. It seems like armor is just a better idea for a top laner. There's potential, but you're going to have to work for it to show.

Overal it is okay.

Few things that bother me though:
1. Your pictures are too big :P, try making them a bit smaller.
2. In your summoner spells section, I could barely find the sentence "non viable spells" due to the size of the pictures :P
3. In the item section there are no pictures :O, you put too much everywhere and then put too little in your item section. Make it a bit more picturesque please :D

The rest is decent, I will not bother you with that :D

Good luck :D

OR rushing Frozen Mallet to get more tanky, and gain decent amount of damage. Btw guide looks good, you should expand it and add more sections, also maybe include situational items to help players adapt to any situation while play as Olaf, this would be a good time to also add Maw of Malmortius into your main build or include it as situational items, which ever you prefer. Good job on the build though. +1

Far too much damage and not enough tanky items early on. I recommend starting warmogs then some damage

No Maw of Malmortius?
