For Online and online strategy:
1.- Website with content. Ideally, a Blog with segmented themes targeted to your audience.
2.- Search Marketing Campaign: making sure you are visible at all times in the search engine.
3.- Once you have your blog with enough content, a paid content distribution strategy with B2C and B2B platforms.
- B2C platforms using native advertising like Outbrain
- B2B platforms using LinkedIn or Content Based Marketing Platforms (it would depend on your budget though)
I would continue with cold calling and mailing as well as conferences.
All would depend on you product/service and budget.
