Who’s online: OkCupid boasts forming more than 91 million connections every year and 50,000 dates made every week. Most of its users are between 25 and 34.
How it works: Algorithms, formulas, heuristics – the site uses a lot of crazy math stuff to help people find their matches faster. Besides the numbers, the mix of straightforward questions, like 
“Do you think it’s important to have an emotional connection before a physical one”, and more lightly revealing ones like “Do you clap when the plane lands?”. With each question, you also note what answers you’ll accept and how important each question is to you. You’ll see a percentage rating on each profile you encounter, letting you know the odds of success.
Features for introverts: You can really be yourself on OkCupid. Whether you’re looking for the relationship of your dreams, a one-night stand, or a sham marriage (seriously, we’re not judging), OkCupid doesn’t care unless you’re being a jerk about it. On OkCupid, you’re more than just a photo, you can share stories, your passions, and pretty much anything else you want and feel totally at home.
If that doesn’t work, the site also offers free dating advice
What it’ll cost you: A basic account is always free. But there are some paid extras you can enjoy if you want a more premium experience. If you pay for the Basic membership, you can cut out the ads, send unlimited likes, filter out your dealbreakers, and see everyone who’s messaged you at once.
If you spring for Premium, you’ll get access to an incognito mode that lets you be invisible to everyone on the site unless you like or message them. Basic memberships start at $ per month and Premium start at $ per month.

How it helps introverts: eharmony has a feature called RelyID that helps verify the information provided by other members, like their name, city, and age. You know what that means? No catfishing.

Results from your personality quiz plus prompts you answer and photos you upload help steer conversation, so you’ll have plenty of jumping off points. But there’s also Guided Communication, a four-step program of communication with your matches, if you need a little extra help. Basically, it’s a series of questions that help to break the ice.

Tentatively, one month of the service will cost you $, three months cost $, and six months go for $. Regardless of current price, eharmony is one of the most expensive mainstream dating sites out there.
