Statista reports that, by 2022, the online dating industry in the U.S. is set to hit more than $1.6 billion in revenue, and the numbers don't lie. Based on traffic figures compiled by Quantcast, Alexa and SimilarWeb, monthly online traffic figures on eBizMBA for the most popular adult dating sites in the U.S. easily reach into eight-figure territory. Additionally, in late 2016, Consumer Reports found that a surprising 44 percent who tried online dating services said their experiences led to a long-term relationship, or even marriage. So if you're looking for love in all the wrong places, maybe try asking for the Wi-Fi password.

Formerly a strictly smartphone-based phenomenon, the browser-based Tinder Online launched in March of 2017, bringing with it an estimated user base of about 50 million people, including 476,000 paid users. Just like the Android and iOS app, the web-based Tinder connects to your Facebook profile and features a simple, addictively game-like interface of swiping left or right on passes and potential matches.

On their list of the best dating apps of 2017, Digital Trends praised Tinder, the king among hookup sites, for having "one of the best user interfaces of any dating app around."

Before Tinder hit browsers, Match.com's 35 million unique monthly visitors, as estimated by eBizMBA in July of 2017, made it the top of the online dating heap. Match goes a bit more in-depth, featuring profiles full of detailed interests and allowing singles to search for others down to specific details, like a mutual love for sushi.

Business Insider says this one "is definitely for a crowd that is more serious about finding a lasting partner."

Sporting an impressive 23 million monthly visitors, PlentyOfFish separates itself from the pack by matching singles using a personality-based chemistry test based on emotional needs. With 70,000 new singles joining each day and a billion messages sent per month, the results seem to be pretty positive.

With 40 million total singles and 11.5 million unique monthly visitors, it's no wonder that Zoosk users send about 3 million messages daily. Like PlentyOfFish, Zoosk uses behavioral matchmaking tech to pair potential mates. Outside the browser platform, its companion smartphone app is the highest grossing dating app on iOS.

OKCupid's 10.15 million monthly visitors answer detailed questions so that the service's proprietary algorithm can match them with compatible singles. Unlike other dating sites, OKCupid is completely free and claims to cater to all sorts of singles, from those seeking marriage to those just looking for a one-night stand.

Clinical psychologist Dr. Neil Clark founded eHarmony in 1997, creating the site based on years of researching relationship compatibility. This one focuses heavily on long-term relationships, introducing singles to a handful of (hopefully) compatible matches every day based on the results of scientific personality tests. Each month, eHarmony attracts about 7.1 million unique visitors.

Badoo attracts about 6 million unique monthly visitors, according to eBizMBA, but overall, the site boasts a network of more than 370 million users. Badoo is about more than just dating, positioning itself as "the largest social discovery network in the world," but its Tinder-like Encounters section focuses more on the casual dating scene.

For Christian Mingle, it really is all in the name. While the format is fairly straightforward, CM focuses squarely on "helping Christian men and women find a loving, God-centered relationship built on mutual faith and love." And that approach seems to work just fine for about 5.5 million faithful singles every month.

Like Christian Mingle, OurTime focuses on a specific niche; in this case, that niche is singles over the age of 50. The service, available both in browser and app-based forms, uses the now-standard swiping format and is free to browse, but requires a paid subscription to use all of its features. Roughly 3.5 million 50-and-up singles visit OurTime each month.

With 3 million estimated unique monthly users, DateHookup keeps the format simple. You create a profile and search for matches based on gender, age and ZIP code. The completely free service also offers iOS, Android and Amazon apps, as well as an active online forum for swapping dating tips and stories. As the name implies, this one caters to those seeking everything from serious romance to casual flings.
