Google帐户已允许绑定多个关联邮箱

Google帐户会默认绑定一个邮箱地址作为主关联邮箱,用户可直接用邮箱信息(比如邮箱地址、密码)登录Google的各种产品及服务。而现在,Google已允许你绑定多个关联邮箱。这意味着同一个Google帐户,可以有多个关联邮箱。要实现这一点很简单,你只需要进入Google帐户的个人信息编辑页面即可操作:你可自行添加多个关联邮箱,但所添加的邮箱: 1、不能是Gmail邮箱2、不能已被绑定至其它Google帐户上

Google新算法表明SEOer需要转型升级

如果在前几年说起SEO这个行业,大家肯定会认为这是一个技术含量极高的活,我刚接触SEO的时候我也非常佩服那些技术很高明的人,比如会黑帽技术,快速排名的人。但搜索引擎经过这么多年的发展,已经趋近成熟。所以马上一个优化的新时代就要来临了,那就是真正去做优质内容的网站和真正去研究用户体验,并满足用户需求的网站将崛起。那些单纯玩技术的逐渐会被淘汰。据国外一则资讯的报导:Google即将对过度SEO的网站进行搜索排名惩罚,优质内容网站将获提升。主要的内容如下: “许多人确实对其网站做了大量的搜索引擎优化。一般情况下我们不会提前公开即将到来的变化,但过去几个月我们确实在做一项工作,并希望在下月或是接下来几周内发布。我们正努力使竞争更加公平。我们所做的,就是让那些没有使用好的关键词、没有做好SEO的,却有好内容的网站能与其它过度SEO的网站平衡。我们正在努力使GoogleBot变得更智能,让搜索结果更相关。也会找出那些在一个页面上有太多关键词,或者是太多交换链接的网站。我们的工程师团队目前正在做这些事情。

为什么新站突然在Google消失

 为什么新站突然在Google消失?很多朋友新网站刚开通,google的收录数量可能就很可观,然而几日之后新站可能突然在google消失。有人说:我的站一点问题也没有,没作弊,没隐藏链接,没采集内容,更没堆砌关键词。出现这种情况实属正常,如果只是排名没了,一般是google沙盒效应所致,如果是google收录全没了,一般是google幽灵现象所致,这些都是因为google对新站有个考核期。  如果你的网站遇到这样情况,并不是受到google的处罚,google肯定还会收录你的网站。这个时候,你就只能把精力放在网站内容上面了,提高网站的质量,争取加入更多的分类目录以及交换更多高质量的链接,不要去考虑排名。从长远来看,一旦google考核期结束,你的导入链接的年龄也足够长了,会被记入算法当中,此时网站也有了足够的内容,那么网站排名就会有一个质的飞跃。  当然并不是所有的新站都会出现这种情况,我们来了解下,为什么会出现这种情况? Google有两种抓取方式:主抓取、新抓取。“新抓取”是主要负责抓取新的网页,当网页被“新抓取”抓取之后,搜索蜘蛛开始衡量该网页内容和质量,并把该网页收录在搜索结果里。这次的衡量是十分不稳定的,易受外界影响,波动性大。如果你的站在搜索结果里排名很高,那么这个搜索结果页面这就是“幽灵登陆页”。幽灵登陆页上的排名不能等同于索引页的排名。在每月新数据库建立之前,google必须将幽灵登陆页从数据库中移走,这只是暂时的移走,于是排名突然消失了。  我们可以这样理解:“主抓取”蜘蛛是没有阅读网站内容的,“主抓取”抓取到了你的站,但是这个网站没有被加入到主索引中。所以,当每月更新结束后,这个新站仍被google看作是新站。当下次更新来临时,“主抓取”蜘蛛将会阅读这个新网站的内容,在经过两次更新之后,该页面才能被收录进主索引。所以当google每月定期更新时,这些网站的排名会有所波动,这期间新网站可能在Google搜索结果页前面,也有可能消失。一个新网站在被Google主目录搜索蜘蛛抓取了,经过一段时间更新,网站被Google主目录正常收录,此时网站的排名才能稳定。

无法超越百度和Google吗

 也许在百度和Google看来他们还没有真正的对手,因为几年前还是互联网盟主的雅虎,今天正在艰难地为生存而拼搏。搜索引擎也一跃成为互联网中与邮件、即时通信并列,最为重要的应用,连各大门户都在显著位置放上了搜索框。无法超越百度和Google原因很多,可能是百度和Google之外的搜索引擎至今还没有给人们一个充分的理由:为什么要用它们?搜索更精确?信息更全面? 搜索市场需要更好的搜索引擎。现在的用户对搜索引擎意见很多:搜索结果过多、死链接、找不到所需要的内容等。搜索引擎的转移成本不高,人们更换搜索引擎可以发生在几秒钟内,不像QQ有很多好友在上面,不方便更换,有网络效应。在互联网上创造品牌不是一件容易的事情,效果的差别如果不明显也不会引起用户转移,所以百度和Google更侧重于扩张。百度和Google投入大量的资金做搜索引擎研发,用来提高效果,百度用闪存取代硬盘就是这个道理。谁想竞争,在技术上必须有较大的突破,资金要充足,推广更要做好。  同时,百度、Google也在防范竞争,扩展其它业务,比如提供基础搜索服务:新闻、音乐、图片。Google与巨鲸音乐网合作,推出免费MP3搜索服务,用意亦在此。谁想竞争,就必须建立同样的产业链。  微软花费巨额资金,到目前还只拥有很少的市场份额,说明了搜索引擎市场中竞争不易。反而是在垂直、细分领域出现了些许机会,生活搜索正在为人们所重视,这是在搜索的深度上做文章,包括城市内的衣、食、住、行等。互联网是一个容易创造神话的地方,没人能预测哪种新业务会取代今天搜索引擎公司的地位。也许,互联网下一个神话就是你创造的!

Google排名算法原创内容的压力

 虽然目前Google对于原创内容的网站,已经有很好的识别判断能力。但是基于原创内容的排序,Google做的还不尽如人意。尽管是原创内容但是在进行关键词排名时,Google确实还考虑了权重、外链、域名信任度等因素。并非只是根据原创内容的所有权,进行排名。大部分熟悉搜索引擎优化的人,都知道。原创内容对于SEO有极大的价值。可以优化搜索引擎排名,提升网站的权重。SEO专家也一直呼吁网站要针对用户、搜索引擎制造出高质量的网站内容。但可能很多在创作原创内容的网站都有这样的体会,自己网站的内容被大量的转载。而搜索文章的标题时,根本找不到自己网站的排名。极大程度的打击创作的激情。日前,美国adage.com网站发表了一篇是关于媒体公司要求Google公司提升原创内容的排名的文章。主要原因是,很多媒体公司不满意Google的PageRank算法,因为PageRank是基于外部链接的排序算法,这使得原创内容的页面在短时间无法获得大量的链接而损失排名。受金融危机的影响,使得媒体公司的广告营收萎缩。出版商们想借用互联网度过此危机,但目前出版商们却因为原创内容无法得到公正的排名,进而影响整体的互联网销售计划。Many publishers resent the criteria Google uses to pick top results, starting with the original PageRank formula that depended on how many links a page got. But crumbling ad revenue is lending their push more urgency; this is no time to show up on the third page of Google search results. And as publishers renew efforts to sell some content online, moreover, they're newly upset that Google's algorithm penalizes paid content."You should not have a system," one content executive said, "where those who are essentially parasites off the true producers of content benefit disproportionately."Last November John Kosner, ESPN's digital-media senior VP, renewed the charge at a meeting of Google's Publishers Advisory Council, a small, invitation-only group for professional publishers to pow-wow confidentially with the search giant. Members include BusinessWeek, ESPN, Hearst, Meredith, The New York Times, Time Inc. and The Wall Street Journal. "This wasn't the first time that it had been raised, but John certainly put a bright spotlight on it," said one person in attendance.Then in January, Martin Nisenholtz, New York Times Co. senior VP-digital operations, got up at the annual Online Publishers Association summit in Florida, an event closed to the press, to blast both the algorithm and the results presentation on the screen.PrioritiesHe'd just run a search for Gaza, which had been at war with Israel since Dec. 27. Google returned links to outdated BBC stories, Wikipedia entries and even an anti-Semitic YouTube video well before coverage by the Times, which had an experienced reporter covering the war from inside Gaza itself.Search results for "Gaza" on March 20 began with two Wikipedia links, a March 19 BBC report, two video clips of unclear origin, the CIA World Factbook, a Guardian report and, most strikingly, a link to Gaza-related messages on Twitter.And every item looks about the same, whether it's a link to Vanity Fair or to FreeGaza.org, undermining the power of known brands. That's especially ironic given Google CEO Eric Schmidt's charge to magazine publishers last October, when he said brands were the way to sort out the "cesspool" that the net is becoming. "Who's actually driving people to these secondary, tertiary and Looooong Tail sites?" one big-time publisher said. "It's Google."Publishers said they're not asking for a leg up over amateurs and link-happy bloggers. "This would in no way mean that only professional content publishers would get an advantage," one said. "It really just says that the original source, and the source with real access, should somehow be recognized as the most important in the delivery of results."Google says it's trying but can't just flip a switch to deliver pro publishers' dreams. "There's absolutely value to original content," a spokesman said. "There's value to derivative content, too. We look at this in many ways from the point of view of the user. But the truth is there are so many shades of gray even within, quote, original content."'Plaintive cry'Not everyone supports the publishers' push. "It's the plaintive cry of people who have lost their monopoly trying to scrounge a little of it back," said Michael Wolff, Vanity Fair columnist and founder of Newser, which aggregates and links news from around the web. "Sometimes it's true that you'd rather get what The New York Times has to say about something rather than a host of bloggers. But more interestingly it's not always true. And it is in fact less and less true."Publishers are nonetheless looking forward to the next closed-door meeting of Google's Publishers Advisory Council on April 30, when many hope to get some solid response from Google. They don't just want "We'll fix it." They want more insight into Google's black box of data and decision making.They're also beginning to cast around for new leverage. Publishers on both sides of the Atlantic are increasingly adopting the Automated Content Access Protocol, which intends to tell search engines what they can use and how. It's focused on copyright, but widespread adoption might give publishers new clout with Google.Some publishers concede, however, they could help themselves more too. "Google has designed an algorithm," one said. "They don't owe us that we show up a particular way. They do publish a whole lot about how to make your site show up as much as possible. If people haven't taken action on it, that's their own damn fault."

Google让你学会鉴别垃圾链接

       在自己网站上使用SEO搜索引擎优化手法,诸如隐藏文字,隐藏链接,关键词堆积,隐藏页面,JS转向等,是比较传统的作弊方式,也更加危险。因为证据确凿,被抓住没什么好狡辩的网站优化服务,证据全在自己网站上摆着呢。   而靠垃圾链接提高排名,就有点说不清道不明的感觉。在博客或论坛群发,就算被检测到,搜索引擎在处理时也会比较谨慎,因为很难断定群发是谁干的。虽然大部分情况下是站长自己干的,但鉴于现在很多人为了排名能变成黑客,也不排除有些人为了陷害竞争对手,给竞争对手群发一下。   所以怎样鉴别和处理垃圾链接是个头疼的问题。搜索引擎头痛,老老实实做站的站长也头痛。   Google的一份专利,标题是:在互相链接的数据中检测链接垃圾之方法,就是研究怎样检测和处理垃圾链接。专利中讨论了很多鉴别链接工厂的数学公式,我完全看不懂,懂编程的可以研究一下。我承认大学时学的高数、线代等一点也不记得了。    这份专利特意提到了两类链接工厂。一种是做一大堆网站,目的就是共同连向一个主网站,使主网站排名提高。这种链接工厂的特征是链接向主网站的这些页面,往往权重(比如Google PR)都很低。而正常的,真正重要的网页通常都会有至少一些比较重要的链接。   另外一种链接工厂是,一堆网站互相之间交叉链接起来。这种链接工厂的特征是,这群网站在链接模式上基本上形成一个孤岛,很少与圈子之外的网站有正常链接关系。   专利中提到被判断是链接工厂或有链接工厂嫌疑的,可能会采取以下措施:  1、这些页面的链接在计算权重时,完全不被考虑    2、页面上的链接权重被降低    3、页面上的链接权重被惩罚    4、这些页面本身重要性被降低    5、这些页面本身重要性被降低,同时发出的链接重要性也被降低   这些惩罚措施都是可以预见的,所描述的两种典型链接工厂也不少见。
