At the end of March, Facebook Connect app friend.ly, a question and answer site designed to help you get to know your friends better and make new friends, hit a sudden growth spurt. It gained 2.3 million monthly active users and 247,ooo daily active users between March 24th and April 13th, according to AppData, our data service tracking growth and traffic for apps and developers

We spoke with friend.ly’s co-founder and chief executive Ed Baker to find out what changes the app made to inspire this growth, how the company is working to accomodate demand, and how it plans to monetize its audience. Baker explained how the growth was aided by the addition of a more compelling mix of questions, that scaling has been a serious challenge, and that it plans to offer premium features to help users get noticed and meet new people.

When users Facebook Connect to friend.ly, the site pulls their friend and Like lists, allowing it to pose questions to the user about the people and things they care about. Other social Q&A services such as Badoo, whose explosive growth we covered last month, focus on asking questions about a user’s friends. Friend.ly’s integration of on the interest graph allows it to know if you Like “Skiing” and therefore ask relevant questions such as “Where’s your favorite place to ski?” This ensures each user’s experience is personalized, leading to more engagement and sharing

Baker tells us that friend.ly’s 10-person Mountain View, California team had kept their heads down “focusing on product for the past year, and just a month ago started focusing on growth.” Friend.ly analyzed data about what questions were being answered, shared to Facebook, and commented on the most to determine what topics it should add more questions to. It also noticed how different types of questions led users to share answers to their own wall, the walls of friends, and Page walls, and worked to intersperse these question types so users could share multiple answers per session without clogging up a certain channel.

The company noticed that the speed and reliability of the site were proportional to engagement, so it strived to make the site process answers and ask new questions as quickly as possible through daily infrastructure improvements. All of these changes combined to result in sizable growth, especially amongst users in the US and U.K.

But now the friend.ly team is scrambling to keep the site up and loading swiftly, spending the $5 million in funding it received from Lightspeed Venture Partners, Balderton Capital and angel investors including Ron Conway, Jeff Clavier, Naval Ravikant, and Michael Birch. Performance has dipped slightly over the past few days, with some pages loading slowly, bugs arising, and the service amassing a backlog of user Like lists that still need to be processed before those users can be asked questions about their interests.

Service is stabilizing now, though, and the company can start turning its attention to how it will generate revenue — something it has yet to tackle. Baker tells us that similar to some dating sites, friend.ly may soon give users the option to pay for added visibility, the ability to send messages to people who aren’t their friends, or know who has been browsing their profile. What sets friend.ly apart from sites like Zoosk and Match.com is that those sites are specifically for dating, and therefore have to pay a lot for advertising in order to gain new users. In contrast friend.ly’s less overtly romantic purpose and the use of Facebook’s viral channel help it gain users organically.

Some might assume that friend.ly would work better as a Facebook canvas app where virality is close at hand than as a Connect site, but Baker wanted the ability to customize the look and feel of the product. Friend.ly also wanted the option to easily pull in information from other social networks such as Twitter.

Perhaps surprisingly, friend.ly doesn’t have a plan to use the wealth of data it’s stockpiling as a core part of its monetization strategy. Instead, Baker believes the product is a success if it can use that data to lead people to become Facebook friends, or even friends offline. “The way people become friends in real life is inefficient. It can be fun and interesting to meet people online, but most dating sites aren’t that fun.” By creating a informal, fast-paced atmosphere where users can meet by asking each other compelling questions, friend.ly has created a service that Facebook users enjoy, and may be willing to pay for.

Gifts, videos, weddings, movies and mobile were on our list of top 20 emerging Facebook applications by monthly active users this week. The apps were mostly in English, a few in Turkish, and one in Polish and grew from between 100,700 and 634,300 monthly active users.

We compile this list with AppData, our data tracking service covering traffic growth for apps on Facebook and covers apps that grew the most in the past week, ending at between 100,000 and 1 million MAU.

A Turkish virtual good app topped our list this week; Send Gift grew by 634,300 MAU by allowing users to send heart-shaped gifts to their friends’ Walls. Then there were two more Turkish apps for videos. Harika Videolar grew by 376,600 MAU and Video Galerisi by 301,700 MAU. The two apps allow users to view, share and Like videos, consequently generating feed stories.

Interestingly, there was about a handful of Page administrator apps on our list this week. Welcome Tab for Pages grew by 241,300 MAU and allows users to create a custom welcome tab for their Pages. FBML Tab Maker added 188,000 MAU by allowing users to create customized FBML tabs. Hy.ly Welcome Tab app saw 101,900 MAU with a welcome tab generator app that helps Page admins create a tab asking visitors to Like their Page. Finally Profiline bakanlar, Seni arayanlar kim ? saw 100,700 MAU this week; the app appears to be a Turkish Page admin tool.

The Movie List Challenges app, which allows users to complete quizzes on which movies they’ve seen and publish to the stream with inviting questions, grew by 237,600 MAU. LiveProfile provides a cross-platform messenger service for iPhone, Android and BlackBerry devices; it grew by 205,900 MAU.

The Polish app Wedding Clock was interesting because it claimed to predict the future; the app grew by 107,800 MAU. The app asks 15 questions to determine your wedding date — such as age, sex, favorite color — and publishes a feed story telling you the anticipated day of your wedding.

Earlier this month, Facebook released an update for the Facebook for iPhone mobile app that included an “Improved news feed”, but no one seemed to understand what had actually changed. We’ve determined that the native app now pulls the news feed directly from mobile site m.facebook.com.

This allows Facebook’s engineers to subtly push news feed design and backend changes to the iPhone without a software update, and lets them maintain one set of code instead of two.

Previously, the Facebook for iPhone app pulled the news feed directly from Facebook private native app APIs. Now the only discernible difference between the news feeds on Facebook for iPhone and m.facebook.com is that the Like and comment buttons rendered by the iPhone app when users hit the ‘+’ button to leave feedback on a story are a little slicker looking.

The update will allow Facebook’s mobile team to spend less time rewriting similar code, and more time improving the user experience and porting features from the Facebook canvas site. The update that arrived last week was the first one in five months on iOS.

Facebook said it was trying to achieve parity between Facebook for iPhone and Facebook for Android, but recently the mobile site has been the first to get new features such as Event checkins. The link between the iPhone app and mobile site’s news feeds could keep Apple’s native Facebook app a small step ahead of Android’s in terms of functionality.

While few users may have noticed the change when the Facebook for iPhone software update was released, the change means their feature and bug fix requests may be addressed sooner.

Update: Another product of the news feed being pulled from m.facebook.com is that users may now Like comments on news feed stories.

As part of our ongoing series on companies offering Facebook’s Ads API tools and services, today we profile Spruce Media. It provides a full-service managed spend Facebook ads solution with a cost per acquisition structure. The company specializes in assisting performance advertisers from verticals including social gaming, group buying, flash sales, ecommerce, and Facebook Pages.

Spruce Media aims to attain the lowest possible costs per action ads for its clients. Founder and chief executive Rob Jewell tells us that he sees full managed spend as the best option for Facebook advertisers as most don’t understand or have the technology to handle the relatively new and complex channel.

For reference, the Facebook Ads API allows developers to create powerful tools and services for designing, targeting, and managing Facebook ads. These are especially important for big advertisers who need better efficiency and A/B testing than what’s available through Facebook’s self-serve performance advertising system.

Company Profile

Spruce Media launched its service in April 2010 after Jewell sold off his previous company, SocialCash, an ad network for in-Facebook app advertising. The San Francisco and Washington, D.C.-based company now has 18 employees, and handles millions of dollars in spend every month.

In Q1 2011, it delivered over 50 billion impressions on a CPA, CPI, and CPL basis for more than 15 clients including LivingSocial, Bigpoint, LOLapps, 6waves, and Toms. It is now one of the world’s largest Ads API companies, and operates in the same space as performance-basis services AdParlor and Nanigans, though it isn’t solely focused on social games.

Spruce Media is centered on its media buying team. Jewell tells us “There are hundreds of creative approaches and optimization strategies to solving the media buying problem. No machine will ever be able to do it nor will a single media buyer.” It therefore assigns five buyers to a client at a time, bringing in a wealth of ad creative and targeting approaches in order to lower CPAs. Once the original team has exhausted their strategies, Spruce switches in another set of buyers.

The company is taking a progressive approach to Facebook’s new ad unit Sponsored Stories. It works with clients to improve the user registration flows on their websites to increase connections to a client’s Facebook Connect app, seeding Sponsored Stories.

Jewell tells us he sees social ad units like Sponsored Stories as the future of Facebook advertising. As such, tools and services focused on search advertising will find it harder and harder to bolt on the Facebook Ads API, and they won’t be able to adapt to Facebook’s rapid release schedule fast enough. Therefore, he believes its crucial for advertisers to work with companies that specialize in Facebook ads.

Service Info

Spruce Media clients set goals for ROI and scale and Spruce accepts the contract if it’s confident it can achieve them. Using its internally developed tool, the company’s media buyers A/B test ad creative and targeting variants, which are managed through a two-screen dashboard. Multiple identical instances of an ad are rolled into the same line item to ensure variants receive a sufficient number of impressions to draw reliable conclusions.

Budget is shifted to high performing combinations using revenue per click and percentage bidding options. Dayparting allows for enhanced optimization, and sparkline and pop-down graphs based on hourly reporting convey performance to buyers at a glance. Some other tools don’t offer these inline charts, requiring users to click through each ad to get an idea of its historical performance.

Facebook and Search Advertising Don’t Mix

Rob Jewell tells us that once the Facebook ad space matures, there might be a market for licensable tools. Until then, though, a performance advertiser’s best bet is to trust their spend to a CPA-based full managed service. He says this works out better than going with an agency-style service who charges a percentage of spend, such as TBG Digital, because those companies aren’t as incentivized to find the lowest possible CPAs for their clients, but instead to just get clients to increase spend.

When we asked Jewell about what the next generation of Ads API features would be, he explained that many tools and services actually still have problems with the basics. For instance, they’re basing their optimizations on single runs of ads variants that might only get 1000 impressions — not enough to conclude if they’re high performers or not. He also told us many tools don’t know to clone and republish successful ads once they start to dip in performance because due to some intricacy of the API, this actually jumpstarts their performance.

Once the basics are covered, he thinks Ads API companies need to focus on conveying the power of the new Facebook ad units and teaching them how change their websites and Facebook Pages to harness the value of units such as Sponsored Stories. Clients need tools and services that are adapting to the shift towards social ads, and that means choosing a service like Spruce Media, not a company anchored to search advertising.

Facebook hired some analysts and interns this week, lost a few recruiters and is in search of software engineers, according to the company’s LinkedIn feed and other sources. And its former Tech Recruiter and Team Lead Andy Barton announced recently that he left the company for Quora.

But most prominently, Google creative director Ji Lee has officially confirmed on his web site that he has moved over to take the same title at Facebook (he’d mentioned the move during a talk a couple weeks ago, but hadn’t said much beyond that).

Jobs posted by Facebook on LinkedIn:

When Facebook Page admins click the Like count beneath their Page’s profile picture, they’ll now see the option to sort those who Like their brand into people, Pages, admins and banned users. From this interface, admins can remove Pages they don’t want to be affiliated with, and unban users who they want to return wall posting privileges to.

As part of the February 2011 Facebook Page redesign, Facebook began allowing Pages to Like other Pages. The new sort ability makes it easy for Pages to see which other Pages Like them, opening opportunities for alliances where Pages link to each other.

However, the ability for Pages to Like other Pages opened an avenue for abuse. Malicious Pages hosting objectionable content could Like innocent Pages and display them in their Featured Likes section, thereby defaming those innocent Page by purporting a connection between the two. Smaller innocent Pages wouldn’t have a problem finding the objectionable Page in the list of those who Like it, but larger Pages would have to manually sift through thousands or even millions of Likes to find the offensive Page and remove it.

Now, admins of larger Pages can sort out all users and just see the Pages that Like them, making it easier to discover and remove offensive Pages.

The ability to sort for banned users gives Page admins the ability to give those who posted objectionable content to their walls a second chance. It appears that previously there was no way to unban users, effectively making all bans permanent. Now, if a user posted something they thought was legitimate but one of a Page’s admins took offense and banned them, another admin could undo this. Another example would be if a user’s account was hijacked and used to spread spam, a Page admin could unban them after they regained control of their account.

By giving Page admins more flexibility as to how they handle moderation, Facebook is becoming a safer place for brands to set up shop and purchase ads.

Ads API managed spend service provider TBG Digital has added two new features to its ONE Media Manager. SmartPages is a multivariant Facebook Page landing tab optimization tool which lets admins test different creative sets to find the best performing version. Daily Deals is a Page tab application through which admins can offer users timed promotions and discounts. The tools drive sales for TBG Digital by giving its clients more things to advertise for.

Multivariant Testing – Not Just for Ads

Ads API tools such as ONE Media Manager typically focus on allowing clients to create and run thousands of ad targeting and creative variants to hone in on the combinations that perform best. In some cases, the objective of the ads is to drive Likes to a Facebook brand’s Page or collect contact information. However, once users click through an ad and visit the Page, they’re often shown only a single variant of a landing tab asking them to Like the Page or submit their email address.

SmartPages brings multivariant testing to this second step, allowing admins to test different images, copy, and webforms to see which lead to the most Likes or signups. Admins can create templates, draw from a pre-uploaded library of images, test up to 15,000 variants at once, schedule variant rotation, and view analytics on conversion rates.

Admins must buy ads through ONE Media Manager in order to test these landing tab variants, generating revenue for TBG Digital. Translating the multivariant testing practices that are common for ads to landing tabs creates a valuable service for TBG Digital’s clients and lucrative new revenue stream. We wouldn’t be surprised to see other Ads API tools and Page management companies offer a similar system.

Integrating Daily Deals Into an Ad Tool

Businesses around the world are becoming interested in offering their customers pre-paid coupons. However, businesses must pay a significant cut of the revenues, up to 50%, if they run these deals through popular distributors such as Groupon or LivingSocial. Promotion application developers such as Wildfire offer flat fee-based Page apps for offering deals, but businesses must then coordinate these third-party promotion apps with their advertising tool to promote their deals.

TBG Digital’s Daily Deals app integrates directly with ONE Media Manager, making it easy to schedule offers and advertise for them without having to pay any additional fee or percentage of revenue outside of ad spend. TBG clients wishing to try offering deals, but who want total control and the ability to pull out if they don’t like the results, may find Daily Deals helpful.

Admins can configure the look of their deals tab through a special admin interface. When users click through a deal, they’re directed to the business’ website where they can complete the transaction. Some users may feel more comfortable entering payment details there than on Facebook, but the added friction of driving users away from Facebook could lead to significant drop-off during the transaction flow.

Most Ads API tool providers are focused squarely on their core business — offering the most streamlined work flow, quickest ad creation, most powerful bid optimization, and deepest analytics. TBG Digital needs to make sure it continues to improve on these areas, but expanding its service offering into Page management through SmartPages and Daily Deals could serve to draw new clients with special needs. However, TBG Digital will need to determine how work in concert with the Page management companies currently running the Facebook Pages of its clients.
