Do we need Facebook and google to generate leads ?

I have a small and relatively successful business. In the last year I feel that nothing is really effective in the field of lead generation. The top of the funnel is dry.... I recently started implementing a method of community-based marketing where small and medium-sized businesses (not competitors) promote each other with a simple method that is based on mutual promotion of digital assets, cross promotion of special offers, mutual promotion of brand content, distribution of mutual recommendations etc
All at almost no cost !!!!
It works really well.
I think it's time to develop a platform that will turn this into a major marketing channel for small and medium businesses. what do you think ?
