Neodymium magnets (or “neo” as they are known in the industry) are graded in strength from N24 to the strongest, N55. The theoretical limit for neodymium magnets is grade N64. The number after the N represents the magnetic energy product, in megagauss-oersteds (MGOe) (1 MG·Oe = 7,958·10³ T·A/m = 7,958 kJ/m³). N48 has a remnant static magnetic field of 1.38 teslas and an H (magnetic field intensity) of 13,800 Oersteds (1.098 MA/m). By volume, one requires about 18 times as much ceramic magnetic material for the equivalent magnet lifting strength, and about 3 to 5 times as much for the equivalent dipole moment.

1) An enterprise to build the ultimate goal of the website is not clear;
2) What kind of website is the most suitable for the needs of enterprises is not clear;
3) Pursue the gorgeous website did not pay attention to the needs of marketing;

Many SEO technics focus on submitting sites to search engines, meta tags, backlinks, and other such methods. While these types of approaches do work, they can be complicated for SEO beginners. And, these techniques can be time-consuming. There is, however, one SEO technique that is perfect for beginner website owners.

This SEO method is quite simple, and should really be the very first technique on which every website owner focuses. All it involves is writing good content.

Many people underestimate the importance of good content on a website and instead put a great deal of time into site design and the aforementioned SEO techniques. But, what these people fail to realize is that without good content, visitors will not enjoy your website. It is unlikely that anyone will visit your site–and, even if they do visit, they will probably not ever come back because there will be nothing to compel them to return.

Good content is what makes people spread the word about a website. Good content is what gets people to sign up for an RSS feed or email newsletter. It is what makes people bookmark articles or pages of a website on various social bookmarking sites–which, in turn, helps to advertise a website. Good content is what makes people email their friends about what they just read about. Without good content, it doesn’t matter how many “share this” or “email this” buttons you have after your articles; no one will want to share what you have written on your website, anyway.

Now, writing good content does not necessarily mean that a person needs to write essays of immense length. Nor does it mean that anyone expects website owners to pen great pieces of literature. Instead, writing good content simply means that the articles and text on the website need to be clear, interesting, and valuable to the reader in some way.

Think about it like this–you would not visit (or revisit) a website that contained no valid or useful information. You would not go to a site that was difficult to read because the text contained dozens of grammatical errors. And it goes without saying that any website that you found to be boring would be one from which you would quickly click away.

So, website writers need to write text in such a way as to keep them interested. But, not only that, writers need to make sure that their content attracts readers in the first place. An article may have good content, but it doesn’t serve a purpose if no one comes to read it, after all.

The way to write good content that attracts readers is through the use of keywords. There are many keyword tools on the internet; choose one that will give you suggestions of which keywords to use in any given article. If you use those keywords for a certain percentage in your article (perhaps from 2% to 5%, though recommendations on this percentage vary), you will likely attract many more readers than if you did not use the keywords.

Writing good content is more important than most other china SEO techniques. You have probably heard the phrase, “Content is king.” This is never truer than on the internet. For every website subject, there are hundreds–if not thousands–of websites devoted to that subject. So, every website has competition; in fact, many websites have a great deal of competition for readers. Without stellar content, a website has little hope of keeping readers–readers will simply head to one of the other hundreds (or thousands) of sites devoted to the same subject.

您面对千万注册用户，欲发送邮件关怀用户时，您的选择是什么，用右键群发软件自己发送还是购买邮件群发服务？

显然，发送对象是您的注册用户，您的邮件发送为合法，您在实施许可电子邮件营销。

众所周知，许可电子邮件营销的最大挑战当属发送的邮件被网络公网服务器大量屏蔽过滤，邮件无法正常发送到达用户端邮箱。

在实施邮件群发时，您多少会遇到类似的问题，

 - 一般的电子邮件群发软件不管用，不管它是免费的还是收费的；
 - 自己架设邮件发送服务器进行群发问题更多，阻挡率高、送达率低，发送速度慢；
 - 您的IP或域名容易被屏蔽，被列入黑名单。

为什么会这样？

这还得从国际通用的垃圾邮件过滤机制说起。

目前，公网邮件服务器（如：Yahoo, MSN）过滤垃圾邮件考虑以下几大因素：

一，发送邮件方的IP声誉（发件声誉）

影响发件声誉的五大指标：

1，用户邮件列表（email地址）的正确性
2，用户投诉
3，垃圾邮件触发（自动捕获网络email地址等非许可邮件行为容易触发垃圾邮件陷阱）
4，邮件安全性基础设施：DKIM认证、SPF（Sender Policy Framework）、SenderID
5，休眠账户（不活跃的邮件订户）

二，是否从固定地址发邮件

三，邮件内容、标题触发垃圾邮件过滤

如使用一些违法、不当、敏感字眼。

四，邮件中含有黑名单中的链接地址（不要赞助声名狼藉的的发件人）

有研究数据显示，邮件被阻挡因素：发件信誉（77%）、发件内容（17%）、被阻URLs（6%）。可见“发件声誉”为最主要的因素。

显然，一般的邮件群发软件无法为您解决“建立良好的发件声誉”的问题。

这就需要借助第三方电子邮件发送服务，俗称邮件发送绿色通道，可以为您，

 - 建立良好的发件声誉，并协调您的网站与ISP之间的关系；
 - 提供专用IP；
 - 加入您的IP/域名于白名单；
 - 邮件发送全程跟踪、监控。
 
第三方电子邮件发送服务因其高效、安全，现已被大多数知名网络媒体、银行、电子商务网站所采用。

网络社区里相互交流着各自电子商务战绩。主流意见颇为一致，那就是，

2009年3月下旬以来，B2C网络订单普遍下降，并且在持续中。

对此，笔者从另一角度做一番感悟。

下图是笔者在Alexa上选取左岸女人vs开心网的三个月中访问用户的停留时间对比截图。

从中我们看到明显变化：3月份开始，一个购物型网站和一个娱乐型网站各自用户停留时间分别出现明显拐点。

我的结论是，

1，网络主体人群在当下网络环境中的“活动能量”是守恒的。更多人经济状况并没有变化，但行为发生“迁移”，从消费迁移到网游或其他娱乐中。
2，“迁移”主因是消费信心的下降。对全球经济的社会舆论是这种变化的主因。

注：网络购买与（PV×Time）可以被认为是正关联。
