Potential Facebook Phishing

Due to working needs, I’ve to explore the Facebook Developer page, in order to learn building my Facebook apps, due to whatever reason, I search for some keywords regarding to developing Facebook application on Google, and without surprise, the result came out with Facebook link on the top, and judging by the content itself, I feel it’s what I want, after clicking it, I noticed the URL is different,

FacebookDeveloper

besides URL, and favicon, everything seems like a legit Facebook page, I wonder why the Google Search result put these in top5 on first page of the results.
