Try to make your description very attractive and pin many many post from your blog. Also, try to pin other stuff, that are interesting for your target audience. I tried to pin videos too, but these doesn't seem to be so apreciate like picture pins, at least for me. Try to pin everyday and a lot of pictures. You'll get a big impact on the feed and people will start to pin it or like it or follow you. Also, try to follow some people from your niche. They might follow you back.
