TECH NOW: Facebook Graph Search rolls out wide in U.S. (USA Today)
Facebook Inc (NASDAQ:FB) has now turned on Graph Search for all of its English-speaking members in the U.S. The idea behind it is to give you a way to mine the massive social network for information that’s most personally relevant to you. For example, I’ve used it to find a new running buddy near my home in Oakland, Calif., and to find the perfect person to recommend for a new job. In general, Graph Search has exciting potential to be your very own version of Google, Yelp, and LinkedIn all rolled into one. Not surprising — since it’s still a newborn, barely-out-of-beta-baby — it’s just not there yet and there will be growing pains.
Finding Ways to Improve Your Marketing on Facebook (The New York Times)
Facebook does in fact limit the reach of your posts. It uses an algorithm to measure reader engagement and determine what type of content users want to see in their news streams. If you want to make sure more of your fans see your content, you can pay to “boost” your posts — although not everyone thinks this is a good idea. (Here is a link to what Facebook says about promoting posts.). When you pay to promote specific content on a Facebook fan page the posts appear higher in the news feed, so there is a better chance that your fans — who have already liked your page — will see them. When you promote a post from your page, you can either choose to show it in the news feeds of the people who like your page (and their friends) or you can try to reach other specific groups of people.
THE TINY BUG THAT ALMOST DERAILED ONE OF FACEBOOK’S HIT FEATURES (Fast Company)
You might think that when a company the size of Facebook is gearing up to launch its first mobile ad product, it would have a large, organized team vetting each and every aspect before launch. But the origins of Facebook’s mobile ad format, which promotes other apps and directs users to their install pages, were a little less coordinated. In the beginning, the team consisted of just Deborah Liu, the product manager who helped launch Facebook Credits, and one engineer. By the time the feature first launched in October, it had added one more engineer. Facebook’s app install ad would eventually become a success story for the social network. Between April and June of this year, more than 8,400 advertisers purchased the install ads, which together drove 46 million app downloads. But for a while, it looked like a flop. “We kept fixing things, and we were like, this isn’t working,” Liu told Fast Company. “The numbers were okay, but we just couldn’t get past it. We kept fixing things, saying, this is going to be the thing that takes us over the top, and it didn’t work.”
