Google Panda

Google Panda is a change to the Google's search results ranking algorithm that was first released in February 2011.^[1] The change aimed to lower the rank of "low-quality sites", and return higher-quality sites near the top of the search results.^[1][2]CNET reported a surge in the rankings of news websites and social networking sites, and a drop in rankings for sites containing large amounts of advertising.^[3] This change reportedly affected the rankings of almost 12 percent of all search results.^[4] Soon after the Panda rollout, many websites,^[5] including Google's webmaster forum, became filled with complaints of scrapers/copyright infringers getting better rankings than sites with original content. At one point, Google publicly asked for data points^[6] to help detect scrapers better. Google's Panda has received several updates since the original rollout in February 2011, and the effect went global in April 2011. To help affected publishers, Google published an advisory on its blog, thus giving some direction for self-evaluation of a website's quality.

okay, fine.

网上相关Dropbox 的报道内容也挺多的了，分享一篇，大纲是比较了云端存储的Dropbox 以及Google的google Drive和微软的SkyDrive的一些现下的特点和功能。 如下：

<Heavy quote>  
"What does it even mean when people talk about storing things in the cloud? It sounds so…nebulous. Pun intended. But don't worry, I'm going to break it down for you.

When people talk about "cloud storage," they are talking about putting documents, pictures, and videos online so that they can be stored and accessed whenever you have an online connection. You need this. 

Anyone who has ever lost files due to a computer crash will vouch for this. Storage to a hard-drive or physical device is important but you want to back up to the cloud too. And now we have options.

Google and Microsoft both rolled out their own cloud-based storage lockers this week, Google Drive, and Microsoft's SkyDrive. They're both competing with the gold standard of cloud storage, Dropbox.

Let me breakdown the differences.

Dropbox has long been my go-to service and they have really defined the category. It is a simple Web site that lets you upload your documents from any computer or mobile device and access them wherever you can get online. The first 2GB of space is free and for most folks that's plenty. The service integrates flawlessly with Mac and Windows and works seamlessly on your mobile phone too. 

Here's a real world example of how I use Dropbox: Mom wants those 50 vacation photos I shot. I upload them to a Dropbox in a folder I call "Vacation Photos". I share the folder with my mom's email and she opens the folder on her computer 900 miles away. It's magic.

Google Drive is similar. It shows a folder on your desktop just like Dropbox but it's integrated with your entire Google experience. You get 5GB of storage for free, which is a pretty good deal, and when you log into Google Documents you'll notice that all your documents, photos, and attachments have become a part of Google Drive. 

If you're a heavy Google user than there's no reason you wouldn't want to use Drive plus it's a great supplement to Dropbox. I personally back up all my photos to Google so now it's an easier experience for me.

If you're a dedicated Windows user and you can't live without Office then look no further than Microsoft's SkyDrive. You get more free storage than Google or Dropbox with a nice 7GB and the cost for an upgrade is cheaper too. SkyDrive integrates perfectly with all of your Office documents, spreadsheets, and PowerPoint presentations whether you're at your desktop or on the go. 

No more emailing yourself the latest version of your PowerPoint presentation. What a pain! Now you can just save the version you're working on in one place and call it up in another when you're ready to work on it again.

Using each service is a matter of personal preference so pick the one that works for you. Just don't wait for a fire or flood before you start backing up your personal goodies to the cloud. Far too many people learn this lesson the hard way.

关注google SEO的同学应该看到一些文章是关于google最新algorithm， algo 更新， penguin 更新，翻译应该是企鹅更新，此次的google算法主要针对的是推广的spam类网站的一个算法，下面是一下网上截获的些许信息：

Google’s Penguin Update, Latest Algorithm, launched on April 24, target spam, so if your traffic dropped on April 24, that would be effected by Penguin update.

同时，在19号就开始的另一个算法更新是老生常谈的panda更新，panda3.5，此次最主要针对的是内容质量不是很好的网站的一个算法更新，以下为零星片段：

Panda 3.5, on April 19 - target pages that aren’t spam but aren’t great quality. The date is important. If your traffic dropped on April 19 and never recovered, then you were probably hit by Panda rather than Penguin.

虽说google声明了更新以及更新将带来的影响，特别是对做关键词推广、自然排名SEO策略营销小型企业的影响，但是，根据网上的一些论坛反映的，确实排名集体骤降，甚至很多内容原创，但是经过SEO优化的网站也经受了此次的连带影响。 

以往的方法还能不能用？不妨继续试试？
