Half of our list of Top 20 growing Facebook applications by daily active users was made up of Connect apps this week — that includes the likes of Yahoo, MySpace, Huffington Post and Hulu. The rest of the list was a mixed bag of Zynga’s CityVille, a few Turkish apps, Groupon, LivingSocial and a couple games. We compile this list with our AppData service.

It’s important to note that Facebook said Tuesday there’s a system bug affecting Connect apps, which means that the rapid growth we’re seeing in some of these Connect apps may be due to the bug and not to actual growth. We’ll be covering that issue as we know more.

20.	Frenziac	184,458	+184,228	+80,099%

Specifically, these Connect apps include: Yahoo, MySpace, Photobucket, Wikia, The Huffington Post, Hulu, Bleacher Report, MetroFlog, Kongregate Games and MyVideo. Some of these saw percentage gains of DAUs in the thousands of percent and in raw numbers they gained anywhere from 3.8 million to 188,900 DAUs.

There were a pair of Turkish games on the list, too. Second on the list was Sanal Video, which grew more than 1,000% with 1.6 million users; the app shows the user a list of top videos to view and then may share on Facebook. Then there was Sanal Okey, a card-like game from Arcade Monkey, which grew by 277,500 users, or 298% percent.

Two more game apps  were on the list this week. That includes AddictingGames at number 10, which grew more than 1,300% adding almost 356,000 DAUs by offering a buffet of games to users and Frenziac at number 20 by TubeYou. Frenziac is an easy game to play where the mouse collects “green blobs,” and grew most of its 184,200 DAUs to number 20.

Two Phrases applications — one in English and one in Spanish — were on the list this week. Phrases by Takeoff Monkey grew by about 260,000 users, but for some reason is no longer available to U.S. users, meaning most of the growth came from elsewhere, specifically Europe, Mexico and the Philippines. A similar Spanish app, Frases Diarias, saw a growth of 217,300 DAUs, 35% growth, by offering users phrases by people like Gandhi and Justin Bieber, in both English and Spanish.

Finally, Groupon and LivingSocial, as well as Windows Live Messenger saw growth on our list this week. And Zynga’s CityVille was there, too, adding a Groupon tie-in of free in-game currency, City Cash, with the purchase of a Groupon flower deal. The app saw a 3% growth of about 507,000 DAUs.

While Facebook appears to have grown by more than 36 million new users around the world in January, according to the data we track in our Inside Facebook Gold premium service, that was not nearly the case in December. The company gained significantly fewer users in the last month of last year versus earlier in the year, although there’s the usual considerable variation depending on which analytics service you look at.

Other factors such as students being away from school on holiday also may have influenced the numbers. While the site is maintaining the growth trend of the last few months, it isn’t matching the enormous gains it saw in early summer.

Here’s what we see. Note that most third-party analytics companies take around a month to report; we’ll be covering January’s numbers from them by early March.

You can see the November third-party data here.

Compete

Beating the peak it showed of 133.5 million monthly US unique visitors in October, Facebook was up to 134.1 million in December  – the most Compete has shown for the social network to date. This represents a rebound from a slight drop to 132.7 millionin November. Meanwhile, among its closest rivals, MySpace fell further from 51.9 million to 47.1 million and Twitter stayed about flat at around 26.4 million uniques.

ComScore

Along the same lines — albeit with a baseline difference of around 20 million monthly uniques — comScore showed Facebook growing from 151.7 million users in November to 153.9 million in December in the US. Worldwide, Facebook went from 647.5 million to 662.4 million monthly uniques. Both numbers tend to skew higher than any other services, although the trend comScore is showing matches data from other services.

Similarly, MySpace fell from 54.4 million to 50.1 million in the US and from 81.5 million to 79.5 million worldwide. Twitter fell slightly from 24.0 to 23.6 million monthly uniques in the US, but grew by around 2 million worldwide. Among Facebook’s competitors (at least in the English language), Twitter’s worldwide growth is the most notable.

Google Ad Planner

While the metrics don’t match up perfectly, Google property DoubleClick pulls from Google Analytics and other services to present a generally good look at what’s happening for other web sites around the world. Facebook, in this case, rose from 590 million uniques in November to around 600 million in December. Meanwhile, daily unique visitors (as based on browser cookies) appeared to stay roughly flat at slightly below 300 million. Facebook has said that around half its users log in daily and this data seems to still be backing that up.

Quantcast

Similar to Compete, Quantcast shows Facebook with nearly 134 million monthly unique visitors in the US in December. Note its weekly graphs indicate a solid rise to 135 million right before Christmas, then a drop, then a slight increase at the turn of the year.

MySpace continued its decline to 28.6 million and Twitter grew to 81.6 million; neither of those numbers are anywhere near what others show, but the directions at least seem to match.

Conclusion

We tracked Facebook gaining around 9 million US users in December to reach 145.7 million monthly actives, so above Compete and Quantcast but below comScore, based on Facebook’s advertising tool. Our worldwide tracked data showed 585.5 million — also below the other available world numbers.

Following a year where Facebook would register across-the-board gains in the millions, December seemed slow. But as we mentioned before, preliminary January data seems to be showing a lot more growth. In the US, it added more than 3 million to reach 148.9 million, for example, according to the ad tool.

Inside Facebook Gold includes our country and region breakdowns of growth, as well as ad rates, demographics, and languages, if you want to get more detail on the monthly trends. Meanwhile, stay tuned for the March version of this article to see what short-term trends go long.

Surprising new traffic trends emerge this month. Facebook continues to grow in markets where (now waning) competitors have historically dominated, including India and Brazil. Meanwhile, many early markets outside the US that first grew big are now plateauing or even losing users.

The biggest standout, however, was the site’s growth beyond the Great Firewall in the massive, and elusive, China market. Facebook CEO Mark Zuckerberg has several times expressed the company’s ambitions in East Asia; this month it looks like Facebook has made progress in the region.

Today at the Menlo Park City Hall, Facebook’s Chief Financial Officer David Ebersman announced that the company will move its corporate headquarters to the Silicon Valley suburb. He explained that Facebook was attracted to the Sun Microsystems campus, as well as support from the city government. Facebook will move all operations to the new campus over the next 12 months.

The campus is 57 acres, can seat 3,600 employees, and has 3,700 parking spaces. The purchase was a sale-leaseback with a 15 year long-term lease, with an option to purchase the campus after five years. There were no tax breaks included in the deal with Menlo Park.

Facebook also purchased the adjacent property owned by an affiliate of Ford Motors. The two properties are connected by an underground commuter tunnel, but Facebook has no plans to develop that property at this time. Facebook is sponsoring three fellows from the Environmental Defense Fund to help make the campus as friendly to the environment as possible.

Rich Klein, Mayor of Menlo Park, said that he’s excited to see if Facebook’s move will inspire other companies to come to the city. He also expects it to boost the local economy as Facebook employees travel offsite for food and other amenities. Public debate will begin in March, possibly in a town hall format, to discuss how the move will impact taxes, spending, traffic, schools, and local business.

Ebersman said that having all the local employees working in the same space promotes sharing and innovation, and that this was no longer possible in its separated Palo Alto offices. When asked how employees are reacting to the announcement, he told us that they are “excited to get back together in one place” after being split between offices.

Employees might not be as excited about the location, though. The area is less developed than Palo Alto’s El Camino Real and California Avenue districts, so employees will have to travel greater distances to get off-site food. This could lead to an increased reliance on the Facebook cafeteria, which in turn could lead employees to spend more time at their desks.

One of the draws of moving to Menlo Park was supposedly to allow more employees to commute without using cars. However, the closest train stop is an 11 minute ride away in one of Facebook’s shuttle buses or a 16 minute bike ride — roughly twice the distance from a train as the Palo Alto offices. For those visiting the campus from San Francisco via public transportation, the trip will take 1.5 hours across multiple buses and underground trains. The could therefore push more people to drive to Facebook, especially considering its ample parking.

Facebook has been rapidly expanding its facilities across the country and internationally, as well as in Silicon Valley. In December it leased two floors with up to 150,000 square feet at 335 Madison Avenue in New York City. That space could accommodate up to 600 people. It has begun construction on a data center in Forest City, North Carolina, and another in Prineville, Oregon that will use advanced energy saving technologies to reduce Facebook’s footprint. Facebook also announced a 500-person office in Hyderabad, India.

Ebersman stated that Facebook’s employee base is growing at 50% a year, and it has 2,000 employees, 1,400 of which currently work in Palo Alto. This means if current growth continues, and the percentage of employees who work in the Bay holds steady, Facebook may need to begin developing the Ford Motors property in as little as three years.

Facebook’s self-serve performance ad tool now allows Page, Place and application admins to create Sponsored Stories ads. The recently launched ad unit allows admins to pay for additional distribution of Page stories as well as user updates that mention them in Facebook’s ad space. Until now, these ads could only be bought through a Facebook managed brand advertising representative.

Sponsored Stories complement other types of advertising and marketing on Facebook, allowing businesses and brands to approach users in multiple ways at once. Sponsored Stories will likely become a component of many ad campaigns on Facebook.

If admins select a Page, Place or application as an ad’s destination in the ad creator, a Sponsored Stories option is revealed. If a Page is the destination, admins can choose to create a Like Story, which “promotes News Feed stories about the viewer’s friends liking your Page”. This type of ad is most effective when it can tell users that multiple friends have Liked your Page, and is therefore best paired with standard Facebook ads, promotions, or tab applications that simultaneously drive Likes, seeding the Sponsored Story.

The other option for Page admins is to create a Page Post Story, which “promotes News Feed stories about your Facebook Page updates.” This can help Pages drive extra clicks to an outbound link, such as to vote in a poll, sign a petition, visit a ecommerce store or get more people to follow another call to action. If the post includes a photo or video, users can click through to see the photo, or watch the video inline.

Application admins have the option to create an App Story, which “Promotes News Feed stories about the viewer’s friends using your App.” Since only users who have the advertised app installed, App Stories are good for re-engaging existing users, but not acquiring new user. Admins of claimed Places should also be able to create check-in stories to promote Places check-ins. This type of Sponsored Story could be used to call attention to a grand opening or sale.

Sponsored Stories ad prices seem to be the same as their traditional counterparts when targeted to the same audience. Metrics about Sponsored Stories appear to be lumped into the social context field in Page Insights. If the advertising community finds that Sponsored Stories perform well, they may shift spend away from traditional Facebook ads to this more complicated, but more persuasive ad unit.

Pick & Zip is a Facebook application that works via Connect allowing users to quickly download photos from Facebook in either a PDF or Zip file, instead of having to use Facebook’s interface for one-off downloads. The app doesn’t require installation, is free and allows for convenient selection of key photos.

After logging in via Facebook Connect, the user is taken to an interface which allows them to hit the “Find my Photos” button and then select from among photo albums and tagged photos, review your selection and then download your photos fairly quickly. There’s a list of friends on the left-hand side of the application to facilitate quick identification of photos you want.

The app is especially helpful for Facebook users who have a lightbox view of photos, since it complicates actually right-clicking to save. However, it cannot be used to cull tagged photos of friends if their privacy settings hide their list of tagged photos

What’s more, for users who want to download many images at a time, if they are archiving, deleting or untagging photos for example, it’s a much preferable alternative to individually saving each of two dozen photos. This is especially true because the downloaded photos end up being the same file size as right-clicking to save.

As part of our ongoing series on companies offering Facebook’s Ads API tools and services, today we profile Clickable’s Facebook Advertising Suite. While clients can also manage search advertising, Clickable Pro handles Facebook advertising in a separate interface so it can quickly iterate on frequent changes to the Ads API. This separation prevents a holistic view of online marketing or a fluid cross-channel budget allocation. The tool also lacks dynamic bid optimization and native data visualization, so clients can’t run Facebook ad campaigns as efficiently as with other Ads API tools.

For those less familiar, Facebook’s performance advertising system offers powerful targeting, but the user interface is not designed for running big campaigns or conducting sophisticated A/B testing. Since the fall of 2009, Facebook has granted a limited number of developers access to an Ads API so they can build more powerful tools and services for designing, targeting, and managing ads.

Company Profile

Clickable was founded in 2006 to simplify search advertising by combining reporting and bid management into a single interface. The New York-based company has received $22.5 million in funding from Union Square Ventures, and FirstMark Capital, as well as Peter Thiel and Founders Fund — both of whom are also Facebook investors.

The company has since grown to 150 employees, opened an office in Gurgaon, India, and now offers self-serve and managed spend advertising on Google, Bing, Yahoo! and Facebook. Clients pay Clickable 10% of spend or less depending on their commitment, though there is no minimum spend, making the tool accessible to those with smaller budgets. Clients come from across different industries and include American Express, LexisNexis, New York Meida, and InfoGroup. To persuade more of its existing search clients to try its social product, Clickable is waiving their fees for trying the Facebook Advertising Suite.

The shared investors helped Clickable gain early access to the Ads API and form a close relationship with the social network so they are informed of upcoming changes. Clickable pledged to update its tool weekly in response to API changes, pleasing Facebook with whom i it now meets several times a month. This relationship ensures consistent service for clients even if Facebook makes major changes that might temporarily break other Ads API tools. On why Clickable separates Facebook from its other services, Senior Vice-President, Product & Operations David Fall says “integrating search and social in the same user interface muddies the waters and is a limiting factor in moving quickly.”

Product Demo

Within the Clickable Pro Dashboard, clients can choose the Social(beta) tab to open the Facebook Advertising Suite and view a recent cost and performance summary of their Facebook ad campaigns. Clients can use drop-down menus to customize special trend reports to see how certain metrics have faired over time.

Clickable’s ad builder uses an innovative non-linear flow, where clients can configure ad creative, targeting, and bidding in whatever order they choose. The campaigns tab shows performance data including the social clicks delivered through Facebook’s special social context ad unit. Clients can also use the bulk uploader tool to import existing data.

Ad Variant Creation and Targeting

The target builder copies the Facebook self-serve ad tool’s UI for a familiar feel, though tags can also appended to ads for better organization, filtering, and aggregated metrics. It also augments Facebook’s keyword suggester with even more possible matches to help clients find additional related targets for their ads. One shortcoming is that audience and bid estimates don’t update in real-time like on Facebook, so clients have to click the “Estimate” button after each change to see approximate reach.

The creative builder lets clients upload new images or use saved ones, and enter a destination URL or select from a list of Facebook entities like Pages they control. Currently, one of Clickable’s biggest problem is the low limit on the number of ad variants than can be simultaneously created. Other tools allow thousands of targeting and creative permutations to be instantly created, but Clickable only permits clients to design up to 32 at once.

Clickable says the choice was made because it is difficult to show thousands of variants in a graphical UI, and so it “felt comfortable with a manageable but somewhat arbitrary limit.” Unfortunately, this significantly hampers A/B testing that can be crucial to finding what targets produce the highest click-through-rates.

Bid Management and Analytics

Ad variants are pre-populated with a suggested bid that can be changed in bulk. They can be assigned to existing campaigns or a new campaign, and are submitted to Facebook for approval within ten minutes.

Clients, or Clickable’s solutions team must then manage bids by hands or using “if…then” rules, since the tool lacks a dynamic bidding engine that can instantly respond to small fluctuations in ad performance. An ad’s bid can only be changed once per hour. This system is highly inefficient, requires constant attention, and can’t scale to campaigns running thousands of ads at once.

The problem is compounded by the absence of custom data visualization that would give clients a better understanding of ad performance. Using filtering options, a client could determine what ads are being clicked least frequently, but without graphs it would be nearly impossible to deduce subtle slips in CTR that signal the need to rotate ad creative.

Clickable Needs Time to Mature

Clickable has a lot of features planned on its roadmap, including upping the ad variant creation limit and offering image hashing to speed up the process of approving ad images with Facebook. Still it doesn’t have plans to address some major functionality gaps.

Fall believes that search and social advertising interfaces shouldn’t pull from the same budget. “Hopefully more Facebook data will be available in the future and social will be more differentiated from search.” However, for now, advertisers have to make tough choices between channels, and many want an advertising platform that can show them when to shift spend from Google to Facebook and back in order to maximize returns.

Despite its rapid release cycle, Clickable Pro’s Facebook Advertising Suite lacks too many core features to compete with better developed Ads API tools. With enough time it could implement dynamic bid management and auto-optimization, and allow clients to view charts and graphs of ad performance. Until then, only Clickable’s existing search clients who can get the social advertising services for free and advertisers looking to experiment on Facebook without a minimum spend should use the Facebook Advertising Suite.

Facebook quietly implemented real-time commenting for wall and news feed posts in late January, allowing users to see new comments by others appear in-line without having to refresh the page. Now it has confirmed that live commenting has been rolled out to all users, and has explained the “write locally, read globally” system on which it’s engineered.

Real-time commenting promotes engaging, rapid-fire conversation and prevents mishaps like one user asking a question that another has already answered.

Facebook can now better approximate a real-life or an instant message conversation within a comment reel. Instead of having to check to see if a friend has answered a question or added details to a post by refreshing, users can simply wait and watch as new comments accumulate.

Real-time commenting will decrease the frequency of unnecessary or redundant comments stemming from update latency. Unnecessary comments can lead Facebook to send notifications leading to irrelevant content to others participating in the comment thread, reducing the likelihood that those users will click through future notifications. In this way, real-time commenting preserves Facebook ability to draw users back to the site.

Facebook’s engineering team considered a polling system for determining when to update a comment thread before settling on a push framework that could reduce latency well below five seconds. Unlike many of the site’s systems that write a new piece of content locally and then asynchronously replicates the data across other regions, Facebook used a new “write locally, read globally” system. It determines which users are currently viewing the active thread and pushes them updates.

Facebook says that the system “saves us from having to replicate a high volume of writes across data centers, saving expensive, long-distance bandwidth.” Like drag-and-drop photo reordering, real-time commenting began as a Facebook Hackathon project where employees voluntarily tackle engineering challenges.

Badoo, the dating app, continues to top our list of growth in terms of monthly active users this week, adding more than 5.4 million users to come out with more than a total of 37.6 million — exceeding any other growing app by far. The app has been criticized by a number of other developers for using aggressive viral tactics that may violate Facebook’s platform policies; we’re checking in with Facebook about that and we’ll update when we have more.

We compile this data by way of our AppData tool. A brief rundown of the rest of the list includes several Connect app, LivingSocial and Groupon apps, as well as MySpace-related apps, sports and Causes (note that Facebook appears to be reporting more data than it has before on Connect applications).

MySpace’s Facebook app rolled in second on our list this week, adding 3.4 million users to surpass a total of 4 million — that amounted to a 572% increase in MAUs. This was coupled by an increase of more than 3.4 million users and a 254% increase in MAUs for the affiliated photo hosting site Photobucket. The reason: MySpace users may now share their MySpace and Photobucket photos to Facebook quite easily.

Other Connect apps were on our list, including The Huffington Post which saw a 2.9 million gain, Wikia which counted 2.7 million MAUs, Hulu with just over 1 million, Yahoo with 840,000 and Bleacher Report, a sports website which saw growth of 727,100 MAUs in the days leading up to the Super Bowl. Groupon at number 7 with a 167% gain of 1.2 million MAUs beat out competitor LivingSocial with 700,500 new users.

There were a few foreign language apps that made the list and show some interesting growth.

Sanal Video is in Turkish, added 1.2 million MAUs, growing by 27% and topping out at almost 6 million users. The app rounds up different videos for a user to play; once a video is selected it plays and allows you to share the video to your stream. My Ad Market is an app in Chinese that did most of its growing in the past week, adding 711,200 MAUs. BandPage by RootMusic added 733,800 new users, continuing the growth we’ve seen on the musician tab app in recent months.

Finally, Causes made the list with a MAU jump of 647,000 to bring the app to 25.8 total monthly active users. Part of its recent promotions have coordinated with Valentine’s Day, urging users to donate $10 on behalf of a loved one to a favorite charity, including Egyptian and Tunisian causes.
