Online marketplaces are typically valued by revenue, community engagement and potential. What is the company's current growth, what is the rate of growth, what is the market share potential, how it is the market, and what are the opportunities that the company affords. These all play a part in valuation. What is the reach? How many subscribers, users, etc all play a part
1) Number of offerings in their catalog
2) Number of active buyers
3) Number of buyers
4) Website traffic
5) Monthly gross sales
and so on.....
Just like any other business, brand and years in business matter as well.
Hope this helps.
