Do you have a marketing budget? If so, try Facebook's power editor to create very targeted newsfeed ads to educators. Don't push a traditional ad. Rather, push great tips and other relevant information. If you write a great short piece, it will lead to click-through's to your blog. Do a similar thing with LinkedIn.

On the organic side, join LinkedIn groups where educators gather. Participate in the discussions. Become a known collaborator.

Post your blog URL any chance you get. There are a lot of free directories. Most are worthless as a directory, but the link-backs do add a little SEO value.

Find out what your educators are using for search terms. Make sure your articles are relevant to those searches.

Create a YouTube video blog - something I am getting ready to do.

Bottom line: Do not "advertise" or self-promote per se. Become known as a content expert and community collaborator and people will start following your blog.

There are lots of ways to get readership. Give me a call if you would like to discuss the options further.
