[QUESTION] Incentives for Soccer niche?

I'm thinking of starting a (local) soccer niche tumblr blog (white-hat)

However, since I'm a noob and can't think of anything, what incentives could I put to get people to refer traffic?

If I was in a health niche for instance it would be a health ebook, but since it's for soccer I have no clue...

Say for instance my niche is chelsea fc, right? and my tumblr blog is all about them, right? what incentives could I use to get people to come to my blog? I'm looking to have about 15,000 people or whatever which is about 10% of the likes on the facebook page of my niche. any ideas?


P.S. For my tumblr blog I'm going to be mostly posting pics, videos that I've made, and discussions about my niche, just to give some ideas.

chelsea ebook, the history of chelsea, chelsea videos- maybe copyright issues there

oh ok thanks, but what exactly do you mean when you say ebook? like what would you put in that? (besides history)

It's going to be real hard to get incentive for those people. You will need exclusive content.
But then again i'm not sure it's worth it, because soccer fans' friends have low chance of being fan of that same team. It will be hard to get targeted traffic from this source.

Build exclusive content, and advertise on social medias related to that topic: groups, fan pages etc etc.

For tumblr in particular, post interesting pics (inforgraphics for example?) and follow/reblog people in the same niche. It will be hard to convert non tumblr traffic to tumblr.

you could giveaway something like chelsea gadget, tshirt something cheap
