Google熊貓更新：對低質量外鏈建設說再見

前陣子，我寫了關於如何獲得最大量外鏈的文章。隨後8個月，Google對其算法進行了的兩次重大改變：第一次針對垃圾/抄襲網站，然後更新到坑爹的熊貓，它針對「低質量」網站。此外，Google對JCPenney, Forbes, 和Overstock.com的黑鏈做法進行了懲罰。

如何確定一個外鏈是否有價值
" }% o. P8 h$ N8 s* v
你怎麼能確定你想獲得外鏈的網站是有價值的？下面是一些危險標誌，Google可能已經或以後會把它認作低質量網站。

大量的廣告。如果該網站頁面被5個AdSense廣告、Kontera文本鏈接，或其他廣告覆蓋，您應該避開它。

缺乏高質量的內容。如果你提交的文章會被立即接受，估計這不是您需要的文章網站。如果這個文章網站接受仿寫或寫得不好的內容，根據搜索算法，google將很難看到你這篇「垃圾中的鑽石」。當然，即使一個網站（例如Suite101.com）提交給編輯的過程極其困難、緩慢，也不能以此把它們作為安全的站點的標誌（他們的問題可能處在ads上）。

" y6 m$ i8 L! m$ I- ?內容很多，流量很低。一個PR為6的Blog可能看起來像一個發垃圾評論的好地方。但是如果這個Blog沒有權威的外鏈和社交網站的分享，那麼它未來很可能會被降權。 根據一些PR7或更高（包括一個PR9）網站情況，更新至熊貓時，一些網站的PR值並沒有被保留。
8 O3 u; u! k' Z$ P3 d  _/ M6 s
鏈接氾濫。特別是Blog的評論和網站目錄。如果你看一個頁面上有一堆垃圾鏈接，你最好不要去湊熱鬧。除非你確定需要一個垃圾外鏈，那就想法加入他們的空缺吧。

Google Panda Update: Say Goodbye to Low-Quality Link Building

    A while back, I wrote about how to get the best high volume links. Fast forward eight months and Google has made two major changes to its algorithm -- first to target spammy/scraper sites, followed by the larger Panda update that targeted "low quality" sites. Plus, Google penalized JCPenney, Forbes, and Overstock.com for "shady" linking practices.
* F. }. O  D% j3 s
    What's it all mean for link builders? Well, it's time we say goodbye to low quality link building altogether.
    'But The Competitors Are Doing It' Isn't an Excuse

- N9 H# N' Y$ l; b4 H7 R1 d    This may be tough for some link builders to digest, especially if you're coming from a research standpoint and you see that competitors for a particular keyword are dominating because of their thousands upon thousands of pure spam links.

    But here are two things you must consider about finding low quality, high volume links in your analysis:
* T6 l0 Z9 G. \3 ]
  R# g' Z$ i2 D3 F        Maybe it isn't the links that got the competitor where they are today. Maybe they are a big enough brand with a good enough reputation to be where they are for that particular keyword.
        If the above doesn't apply, then maybe it's just a matter of time before Google cracks down even further, giving no weight to those spammy backlinks.

0 g0 S9 ]. b" e- i    How can you determine whether a site you're trying to gain a link from is valuable? Here are some "warning" signs as to what Google may have or eventually deem as a low-quality site.
& \; E+ I: J/ f
9 F8 K& T# P. C9 ^4 ?4 C" v  w, H        Lots of ads. If the site is covered with five blocks of AdSense, Kontera text links, or other advertising chunks, you might want to steer away from them.
+ X' Z0 F6 U- j" k! Q        Lack of quality content. If you can get your article approved immediately, chances are this isn't the right article network for your needs. If the article network is approving spun or poorly written content, it will be hard for the algorithm to see your "diamond in the rough." Of course, when a site like Suite101.com, which has one hell of an editorial process, gets dinged, then extreme moderation may not necessarily be a sign of a safe site either (in their case, ads were the more likely issue).
        Lots of content, low traffic. A blog with a Google PageRank of 6 probably looks like a great place to spam a comment. But if that blog doesn't have good authority in terms of traffic and social sharing, then it may be put on the list of sites to be de-valued in the future. PageRank didn't save some of the sites in the Panda update, considering there are several sites with PageRank 7 and above (including a PR 9).
- R5 A; }- U* S1 _/ \% J# ?1 w        Lack of moderation. Kind of goes with the above, except in this case I mean blog comments and directories. If you see a ton of spammy links on a page, you don't want yours to go next to it. Unless you consider it a spammy link, and then more power to you to join the rest of them.

雖然不想說啥，但還是忍不住吐槽：內容太老了，另外，一個頁面放不了5個adsense.。。

湊副看看，新手也能長點知識。

很不錯的資料。以前弄了不少垃圾外鏈。關鍵是高pr的Blog只要能發評論的，大部分都是幾百成千的帶鏈接的評論。

你說得那幾個大站，不至於做黑鏈吧？個個都是超有錢的公司啊。。。隨便拿點地面推廣的錢都夠買好多鏈接了

毫無價值的帖子

自動鏈效果不好，手動又太辛苦，買鏈又太費錢......

鏈接太難搞了。。
