Online dating services like eHarmony and Chemistry.com have long emphasized their ability to find “quality” matches based on matchmaking algorithms. Even dating app Tinder, known as more of a hook-up app than a true matchmaking service, is getting in on the long-term love strategy. The company just released a new version, with updated algorithms that Tinder CEO Sean Rad maintains will lead to “more meaningful matches.”

Matching algorithms work like this: If you craft a profile with your interests, hobbies, income, and other descriptors, and you identify the qualities you are looking for in a match, then voila – the online dating site will find those candidates best suited for you. In other words, they will find people with similar preferences, interests, and backgrounds and match you together.

Which means that there’s a higher likelihood of the two of you falling in love and living happily ever after, right?

Not necessarily. Some writers point to research that says otherwise. As The Washington Post shared in a recent article: “Dating site algorithms are meaningless. They really don’t do anything. In fact, the research suggests that so-called ‘matching algorithms’ are only negligibly better at matching people than random chance.”

The reasons behind this conclusion are varied, but the basic idea is that chemistry between two people is highly variable. Just because you might match up well in theory, (and online), doesn’t mean that the spark will exist in real life. But the dating sites want you to believe otherwise.

There is an argument to be made that people who are considered “compatible” or who have the same background, communication style, or any number of factors in common might make better matches. And they might – or they might not. According to one very prominent study from 2012 conducted by Northwestern University’s Eli Finkel on the matching algorithms used by online dating sites, there was just as good a chance that someone you meet at random could end up being the love of your life.

According to Finkel’s study, relationship success depends on three things. First, individual characteristics, like whether you’re smart, funny, consider yourself beautiful, or avoid commitment at all costs. Second, the quality of interaction between two people - specifically how you hit it off in-person, not through text messages back and forth. And third, your surrounding circumstances, like your career, ethnicity, financial security, and health.

As we know from online dating sites, we aren’t always accurate or truthful when we are describing ourselves, so it’s likely we aren’t as compatible as we think. Another problem is that compatibility isn’t the marker of a good relationship. It really comes down to that elusive thing called chemistry and how you interact together in person.

With this information, it’s to every dater’s benefit to accept more invitations and matches, even those who don’t seem to be suited for you. Because the truth is, until you meet, you just don’t know.

How will technology change the way we date over the next 25 years? Virtual reality, DNA testing and wearable technology could all be part of the picture.

A recent report from Imperial College Business School in the United Kingdom, commissioned by eHarmony, explores how we'll date in the future. The report analyzed over 100 years’ worth of trend data and interviews with experts in multiple fields to predict how dating and relationships could change by 2040.

"By 2040 we estimate that 70 percent of couples will get together online, with technology revolutionising the way we find love and build our relationships," said Romain Bertrand, eHarmony UK manager, to The Telegraph.

Lone Star Introductions, a matchmaking service operating in the state of Texas to help singles find love, was forced to cease operations and pay restitution to its former customers. According to Texas Attorney General Ken Paxton’s office, the judgment came from a lawsuit against the Massachusetts based company ‘for violating the Texas Deceptive Trade Practices Act and Texas Internet Dating Safety Act.’

A state district court issued an injunction that calls on the dating service and affiliated dating sites, including eLove Matchmaking, International Dating Ventures and International Introductions, to cease operations in the state. Lone Star Introductions was using multiple company names to pursue its aggressive tactics, and was informed by the state of Texas two years ago that they were being investigated.

The attorney general says the company uses lead generating companies to mine online dating services for customer contacts, then uses the information to make cold calls in Texas, without registering as a telemarketer. They would pressure prospective clients to meet in the Lone Star Introductions offices to sign expensive contracts for dating services which they would then not provide.

According to website Courthouse News, Lone Star Introductions was particularly ruthless when it came to getting money from vulnerable clients. According to court documents, once Lone Star would get a phone number, they "use high pressure and coercive tactics" to try to get targets to sign up, including "incessant phone calls," coercion and manipulation. "Defendants charge consumers between $7,995 and $12,995 for prospective dating introductions," the state says.

Lone Star calls its telemarketers "counselors,” but according to Paxton’s office were little more than aggressive telemarketers.

Courthouse News goes on to note the following from the lawsuit: "Consumers who complained to defendants and requested to cancel their contracts are harassed and threatened by defendants with financial ruin and criminal prosecution. One consumer alleges that an eLove representative 'yelled four-letter curse words at [him], threatened to destroy [his] credit, prosecute [him] for a felony, and report [him] to the Texas Attorney General's Office' when the consumer attempted to cancel his contract."

According to Paxton’s office this type of harassment and threat to consumers violates debt collection regulations. Also, the “Counselors” at Lone Star Introductions failed to comply with the Texas Internet Dating Safety Act, which includes advising customers of safe dating practices.

The final judgment ordered the defendant to pay $500,000 in civil penalties and pay $20,000 in restitution to customers.

eHarmony is saying 'Hola!' to a new site designed to serve Spanish-speaking singles. The company says the new addition to the eHarmony family, eHarmony.com/espanol, will provide a fully translated, localized experience for the 37 percent of bilingual users who speak Spanish.

As always, eHarmony used its famous research-based approach to build the compatibility model that is the backbone of the Spanish site. To update it for a new audience, the algorithim now takes into account linguistic and cultural nuances that are important in the matching process.

“In the last few years, we have seen online dating come into its own and today we are seeing growth in every user demographic,” said Dr. Neil Clark Warren. “That trend continues around the world as online dating is recognized as a way to meet someone special. Our purpose has always been to help our users find lasting, meaningful relationships and the launch of this site represents another way to reach those who are hoping to be found by that perfect partner and confidant.”

The development of this new site speaks directly to the company’s continued growth as a global brand. eHarmony hopes to appeal to an increasingly large demographic of online daters in Latin America, where online dating is growing at a rate of 20 percent year over year according to independent market research.

New features will become available on the site in the coming months, including mobile access and localized experiences for Spanish-speakers around the world. Beginning in December, current eHarmony users can elect to fill out a mini-questionnaire in Spanish to be better matched with those who set up their profiles in Spanish.

eHarmony has every reason to be invested in its global growth. According to a report published on eHarmony.co.uk, 50 percent of all relationships could begin online by 2031. By 2040, that number could jump to 70 percent. As profits increase along with the number of users, eHarmony wants to be at the forefront of every new development.

To celebrate the release of eHarmony.com/espanol, eHarmony has introduced a friends and family special. New users can get three months free when using the promo code “AMIGOS2015”. eHarmony.com/espanol is currently available in the United States and will be introduced in several other countries, including Mexico and Spain, over the course of 2016.

Usually makeovers come with the New Year and the soon-to-be-forgotten resolutions, but Spark Networks is starting early. The company has given its two most recognized brands, JDate and ChristianMingle, a head-to-toe refresh for the end of 2015.

Both brands have been redesigned inside and out. In addition to sleek new appearances, the sites have been updated with improved back-end platforms, new mobile-optimized features and easier-to-use functionality.

This is all part of Spark Networks' year-long strategic vision for boosting profits and subscriber engagement. Despite its strong legacy in the online dating business, Spark Networks had stalled while the rest of the industry modernized. With the relaunch of its two core brands, the company hopes to reposition itself once again as a leader in the niche dating world.

JDate is the first of the two legacy brands to debut the results of its makeover. Some of the updates and new product offerings include:

• A cleaner, more streamlined user experience that simplifies interactions
• A new “daily matches” feature that presents a curated collection of matches tailored to each member
• An improved user experience for iPad/tablet users
• An expanded mobile presence and improved mobile capabilities
• A redesigned inbox to make interactions between users even easier

ChristianMingle has not yet debuted its renovation, but look for it in the coming weeks. Not only will it incorporate many of the features from the new JDate platform, it will also reposition the site as a more open, contemporary and diverse community based on the Christian faith and values.

After a year of ups and downs, this could be the breakthrough Spark Networks has been looking for. The company revealed a drop in year-on-year revenue and a net income loss of $822,000 for the quarter when it shared its Q3 2015 financial results. On the plus side, subscriber growth was on the uptick for the first time since Q1 2013 and Spark's mobile presence has expanded significantly this year.

“At the beginning of this year we set an aggressive plan to rebuild our two key brands – JDate and ChristianMingle – to become relevant again to our customers and drive fundamental change in business performance,” said Michael Egan, Chief Executive Officer of Spark Networks.

“It has been an exciting and successful year with tremendous growth and development momentum. The changes and upgrades we are debuting today are the first step to strengthening our portfolio to become more nimble and innovative, as we build valuable products and services for our members.”

‘Tis the season! The holidays are upon us, which means that despite the cooler weather, our options for date ideas really open up. After all, parties and celebrations are everywhere---there’s no need to rely on the typical night of Netflix and dinner at home.

While popping some prosecco and lighting a nice fire in your living room are always good options for getting romantic, let’s think outside the box (meaning outside your apartment). What are some cool date options for someone you’re starting to really warm up to?

Following are some ideas to get you started:

Check out the lights in a cool neighborhood. No matter the city, there’s always a street or two that decorates like crazy – enough to attract small crowds during the holidays. This is a fun way to get into the holiday spirit. Do a little online research and pick a neighborhood, then go exploring – on foot or by car.

Go ice skating, sledding, or hiking. Even in Los Angeles, we have outdoor ice rinks during the holidays (as well as imported snow). So even if your city is not known for its icy lakes, chances are, there’s an outdoor ice rink to check out. (And for my friends in warmer climates this time of year, you have lots of outdoor options!) If you are blessed with cold weather options, try sledding, skiing, or hiking in the snow – or building a snowman. The point is: get outside and enjoy.

Volunteer. Sometimes we get so caught up in our own lives that we don’t make time for others. Volunteering helps us get in the spirit of the holidays and also reminds us of all that we have. It’s a great way to feel inspired with your date.

Build something together. Do you have a project you’ve been wanting to tackle? Perhaps you want to build a new bookcase, or put together a dollhouse you’d love to give your niece, or refinish the antique table in your backyard? Now is the time to take on this project – and doing it with a date makes it fun. Crack open a bottle of wine or go out to dinner as a reward.

Visit a Christmas tree farm. Nothing says Christmas quite like the smell of fresh cut pine trees. Pick out a tree together to take home and decorate, or just walk around and enjoy the atmosphere.

Go to an outdoor Christmas market. Outdoor holiday markets are big in many parts of the world, and offer a great variety of shopping, food, and warm mulled wine for the Christmas enthusiast. You can get errands done and enjoy the experience. Plus, it’s a festive way to spend the evening with a date.

Visit a sauna/ have a couples massage. Sometimes, you need a break from the holiday spirit. Why not treat yourself and your date to an afternoon sauna, or a nice couples massage? Consider it your holiday gift to yourselves.

Attend a festival. The holiday season is nothing if not festive. There are plenty of concerts and festivals – whether it’s wine and beer tasting, live music, a food festival, or holiday open houses, there’s always something to attend. Do a little research, and if you live near a big city, make it a day trip for you and your date.

Happy holidays!
