If you don't have much money or time, use the SHOCKING PRESS RELEASE strategy used by OKCupid and Pornhub
How? Find something SHOCKING in your industry, do a 'survey' and publicize the results on your target site's announcement area/blog
Get that info in front of the eyeballs of REPORTERS / MEDIA on Twitter
Since they're always looking for something new or "hot" your story might get picked up
Once picked up, other media will syndicate the story

Create tons of Question and answer content and get ready to wait!
