Bing introduces new local deals to mobile- Bing introduced  a new deals service for their mobile and PC search engine. The deals are not being generated directly by Microsoft, but are the result of a new partnership with The Dealmap . The Dealmap is currently available on Android and iPhone devices, and connects Bing with “more than 200,000 offers in over 14,000 cities and towns across the U.S.” According to The Dealmap’s co-founder Chandu Thota , "The DealExchange is the most comprehensive platform for sourcing, distributing and monetizing local deals. Working with a technology leader like Microsoft bolsters our leadership position and highlights a period of explosive growth for The Dealmap. We look forward to continuing to collaborate with Microsoft in ways that will deliver value to consumers and continue to rapidly grow our business." How do you think Google will respond to Bing's latest move in local search? Smartphone race still raging- A new reported from Nielsen  revealed this week that the smartphone race is still alive and competitive.

Google’s Android app developers are more popular than Apple’s- This week, engineers developing apps for Google’s Android system became even more ‘sought after.’ According to information from the online job board Dice.com, there were 987 employer job request postings for Android developers, compared with 970 job listings looking for engineers with Apple expertise. According to Douglas MacMillan from Business Week , “Demand is swelling for Android programmers as Google woos makers of mobile applications to keep up with the growing popularity of its software. Android became the world's best-selling smartphone platform last year, according to researcher Canalys, yet it trails in total number of apps, with more than 120,000 compared to the 350,000 programs in Apple's App Store.” Conversation around Google’s farming continues- Last week Google updated its search engine to address the growing problem of content farms, or what Google perceives to be low-quality content sites, which often outrank more relevant, original content in Google’s SERP. The change is one of the most dramatic Google has made to their algorithm, affecting an estimated 12 percent of all its search results. Stephen Levy conducted an interview  with Amit Singhal and Matt Cutts, who announced  the change in a blog post last week, to discuss the change and the impact it will have on search results.
