We spent five days trying out 10 different online dating services to figure out which one is the most effective and affordable. That meant monitoring three fake profiles for 24 hours, collecting match data and using the features of every website and app. We looked at which websites give free access to other users’ profile photos and messaging, and whether you have to pay to access extra features. For on-the-go dating, we also used apps and evaluated them based on how user-friendly they are.     
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 A-List membership, you can cut out the ads, you get more search options like body type and attractiveness, you can see everyone who likes you, and you can see who reads your messages, among other useful things. 
Match is one of the most famous online dating sites, and for good reason. Running since 1995, Match really knows what it's doing in terms of pairing people looking for love and offering an extremely smooth user experience. While many singles these days opt for hookup apps and jumping from fling to fling, for those truly seeking committed relationships, Match is one of the best options for you.
How does it work? There are no gimmicks or USPs with DatingDirect. In fact, it’s fairly similar to our old friends Match, mentioned above. You can start looking at potential dates for free, then when you like the look of someone and fancy striking up a conversation, you need to subscribe. Like a lot of the best online dating sites, it also has a handy instant messenger service which makes chatting to your matches easy and breezy.
When someone wants to register on a dating site, they will first need to create their profile online. A few sites have long questionnaires which help to generate a detailed profile of their character, and these are valuable for those who want a life-partner, marriage, or a soul mate. Other sites just want your basic information, such as hobbies, likes, dislikes, age, and occupation.
Now that you've perused the dating pool and have your eyes on that special someone, it's time to bite the bullet and actually reach out to him or her. Each app offers different ways of showing your interest, but in most instances, this is when you have to open your wallet. Match will let you Wink at a fellow member for free, and Plenty of Fish doesn't charge for messaging, but in almost all other instances you're going to get charged for the reach-out. If you're not ready to express your feelings in words, Bumble lets you send Bumble Coins to prospective matches, for $2 a pop. Zoosk offers the slightly creepy option of giving Coins to other users to express your interest (for an additional fee, of course).
Signing up took us about 20 minutes during testing, which is more than twice as long as most of the websites we tested. You answer questions about not only about your appearance, but also about your religious beliefs and career. You then fill out a comprehensive survey regarding what you want in a partner. The questions even go as far to ask whether you want to have kids, which is an important thing to agree on if you're looking for a long-term commitment. You have to pay for a subscription to access most of the features on eharmony, and even though we couldn't read them with a free account, we got nine emails in 24 hours, which was a pretty decent response rate. There is also an eharmony app that's easy to use, making this a great service to try if you want a thorough experience.

Sometimes, opposites attract! Choose the people you are interested in instead of being automatically matched with someone. With Cupid.com®, the Internet dating no longer has to be a boring, complicated process. We let you jump right into meeting single men and single women in your area without having to jump through a lot of hoops. We are truly the best dating service available today.

Why it's awesome: Plenty of Fish, sometime styled as POF, boasts 4 million daily active users, with 65,000 new users each day, apparently, and claims users send 1 billion messages per month. After registering for POF, hopeful daters take a personality test that then helps POF determine what they call, "Your Relationship Needs." Basically, it's a way to make sure users know what they want from their love lives, and to ensure that it serves users other profiles that meet that criteria. One unusual quirk: The site recently launched a feature that allows users to message others through Google Home. Says Spira: "They have a large user base, are a free site, and are very popular."
This app wants to find you more than just a one-night stand or a cool-for-the-summer situation. That said, you're going to have to work for it. To join, you have to fill out an extensive survey, and you can't see photos of your potential matches unless you pay to subscribe. If you're out to spend more time finding your mate, eharmony is a good (if more costly) option. That is, as long as you're not looking for a same-sex mate: That's not an option here.

I was on Clover for quite some time, but had since forgotten it existed until I started to compile this list. It strikes me as a less-successful hybrid of OkCupid and Tinder with a relatively small user base, even though I live in an urban area with plenty of people who use a wide variety of dating apps. Clover says it has nearly 6 million users, 85 percent of whom are between the ages of 18 and 30.

Features for introverts: Since AFF has millions upon millions of users from around the world, there’s always a large group of people constantly using it 24 hours a day. No matter your kinks or sexual orientation and no matter the time of day or night, there’s someone on the dating site waiting for you to share your preferences, sexual desires, and maybe hook-up with you too. It’s like if New York City and Las Vegas had a baby. Adult Friend Finder is the dating site that never sleeps and whatever happens on the site, stays on the site.
