Guest post, guest post, guest post. I write guest articles for other blogs and also invite bloggers to contribute towards my blog. In this way network is built. Both the blogs get famous.
After completing your post, read it with a fresh eye from the perspective of a reader to check if you enjoy it or if it needs changes.
Image speak - A lot of bloggers tend to ignore this, but the images on your blog speak a lot for what you write. Use good quality images and make sure they express your written stuff in utmost simplicity yet precision.
