Requirements For Event Blogging


I have seen many Bloggers hitting Gold in the field of Event Blogging. So i wanna know what can be the techniques to do EVENT Blog successfully. Are there any tools or something like that. Like we can build Backlinks manually! What else we can have for the same?
I tried experimenting for a minor niche competiton for Event Blog, i was able to rank it via Backlinks. But it is time consuming as well as it can also be dangerous for SEO too! Please Suggest for the Same!
