Ditto to all of the above. Since you say it's a product, rather than a service, I'd also find some bloggers who do product reviews in your niche and pitch them about reviewing your product. Also, another way to get publicity can be to join services such as H.A.R.O. (Help A Reporter Out) and Pitchrate and respond to the queries in your niche. (They're services where reporters post inquiries when they're looking for experts for stories they're working on and products to review.) BUT--and this is a major one--before responding to queries, really learn the proper way to pitch a reporter, and be sure you have an online media kit containing the things they'll actually need, in the form they need them. Journalists who use HARO and Pitchrate are pros who expect a strong level of excellence, and there are very specific ways of how to approach them. I can show you how to do this if you'd like to schedule a call.
