Q: How many online dating sites are there in the United States?
A: Online Dating Magazine estimates that there are approximately 2,500 online dating sites in the United States and more than 5,000 online dating services worldwide.
Only a small handful of those online dating services in the United States, fewer than 25, are considered “major”. Major is defined as “online dating services which have more than one million current, active, and unique members”.
The largest online dating sites in the United States are Match.com, eHarmony.com, and OKcupid. Some sites located outside of the United States, like Plenty of Fish, also have millions of members from the United States.
According to Online Dating Magazine, 99% of all new online dating services will fail. This is because online dating services require a huge up-front investment in order to attract the number of users needed to be effective. The majority of new services have no upfront investment.
