Where do you see the best ROI with Internet buyer/seller leads?

[Greg Ryan]

I have recently formed a team with 2 agents. We've invested $$ into several sites like zillow/Realtor.com and we have used sites like OPcity and Homelight for buyer and seller leads.  We have also gone through the NINJA training and practice a Sphere of Influence based business with Client Events, Autoflow, Direct mail, Hand written letters.  We have also spent $ on social media platforms.   We are in the process of trimming the fat and I would love to hear from some experienced agents that have had great success with capturing quality buyer/seller leads through spending Marketing $ to websites.
