As you have mentioned "in a particular niche",
-you need to have an industry analysis of your niche, and find out the optimized keywords that will suit you and drive traffic.
-Targeting those keywords optimize your content and go for some off page works to get rank in first page.

-Apart from that facebook, twitter update of your blog is necessary.
