Seeking Advice on Web Service Internationalization

I agree with @vladimir_zivkovic. I would start with one market personally - get to know everything about it in terms of success and failures. Then take those learnings to the next market. I would prioritize you markets by either: - Most experience in or knowledge of - Largest ability to gain traction in new market (either because of lack of competition or name recognition (yours or the company's) Having done a lot of international digital marketing for the last 15+ yrs, each country is very different and having the time to properly market (seo, social media, etc.) to multiple at 1x requires a very good (large) team. You would not be doing yourself any favors spreading yourself so thin trying to market to multiple countries right out of the gate. You could get away with marketing to US & Canada at the same time, and the US and UK (if you have the time to do proper keyword research and content optimization to reach both audiences). HTH!
