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.

網上相關Dropbox 的報道內容也挺多的了，分享一篇，大綱是比較了云端存儲的Dropbox 以及Google的google Drive和微軟的SkyDrive的一些現下的特點和功能。 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.

關注google SEO的同學應該看到一些文章是關于google最新algorithm， algo 更新， penguin 更新，翻譯應該是企鵝更新，此次的google算法主要針對的是推廣的spam類網站的一個算法，下面是一下網上截獲的些許信息：

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.

同時，在19號就開始的另一個算法更新是老生常談的panda更新，panda3.5，此次最主要針對的是內容質量不是很好的網站的一個算法更新，以下為零星片段：

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.

雖說google聲明了更新以及更新將帶來的影響，特別是對做關鍵詞推廣、自然排名SEO策略營銷小型企業的影響，但是，根據網上的一些論壇反映的，確實排名集體驟降，甚至很多內容原創，但是經過SEO優化的網站也經受了此次的連帶影響。 

以往的方法還能不能用？不妨繼續試試？
