SEO is an abbreviation for "search engine optimizer." Many SEOs and other agencies and consultants provide useful services for website owners, from writing copy to giving advice on site architecture and helping to find relevant directories to which a site can be submitted. However, a few unethical SEOs have given the industry a black eye through their overly aggressive marketing efforts and their attempts to unfairly manipulate search engine results.

While Google doesn't have relationships with any SEOs and doesn't offer recommendations, we do have a few tips that may help you distinguish between an SEO that will improve your site and one that will only improve your chances of being dropped from search engine results altogether.

• Be wary of SEO firms and web consultants or agencies that send you email out of the blue.

Amazingly, we get these spam emails too:

"Dear google.com,
I visited your website and noticed that you are not listed in most of the major search engines and directories..."

Reserve the same skepticism for unsolicited email about search engines as you do for "burn fat at night" diet pills or requests to help transfer funds from deposed dictators.

• No one can guarantee a #1 ranking on Google.

Beware of SEOs that claim to guarantee rankings, allege a "special relationship" with Google, or advertise a "priority submit" to Google. There is no priority submit for Google. In fact, the only way to submit a site to Google directly is through ourAdd URLpage or through theGoogle Sitemapsprogram, and you can do this yourself at no cost whatsoever.

• Be careful if a company is secretive or won't clearly explain what they intend to do.

Ask for explanations if something is unclear. If an SEO creates deceptive or misleading content on your behalf, such as doorway pages or "throwaway" domains, your site could be removed entirely from Google's index. Ultimately, you are responsible for the actions of any companies you hire, so it's best to be sure you know exactly how they intend to "help" you.

• You should never have to link to an SEO.

Avoid SEOs that talk about the power of "free-for-all" links, link popularity schemes, or submitting your site to thousands of search engines. These are typically useless exercises that don't affect your ranking in the results of the major search engines -- at least, not in a way you would likely consider to be positive.

• Some SEOs may try to sell you the ability to type keywords directly into the browser address bar.

Most such proposals require users to install extra software, and very few users do so. Evaluate such proposals with extreme care and be skeptical about the self-reported number of users who have downloaded the required applications.

• Choose wisely.

While you consider whether to go with an SEO, you may want to do some research on the industry. Google is one way to do that, of course. You might also seek out a few of the cautionary tales that have appeared in the press, including this article on one particularly aggressive SEO:http://seattletimes.nwsource.com/html/businesstechnology/2002002970_nwbizbriefs12.html. While Google doesn't comment on specific companies, we've encountered firms calling themselves SEOs who follow practices that are clearly beyond the pale of accepted business behavior. Be careful.

• Be sure to understand where the money goes.

While Google never sells better ranking in our search results, several other search engines combine pay-per-click or pay-for-inclusion results with their regular web search results. Some SEOs will promise to rank you highly in search engines, but place you in the advertising section rather than in the search results. A few SEOs will even change their bid prices in real time to create the illusion that they "control" other search engines and can place themselves in the slot of their choice. This scam doesn't work with Google because our advertising is clearly labeled and separated from our search results, but be sure to ask any SEO you're considering which fees go toward permanent inclusion and which apply toward temporary advertising.

• Talk to many SEOs, and ask other SEOs if they'd recommend the firm you're considering.

References are a good start, but they don't tell the whole story. You should ask how long a company has been in business and how many full time individuals it employs. If you feel pressured or uneasy, go with your gut feeling and play it safe: hold off until you find a firm that you can trust. Ask your SEO firm if it reports every spam abuse that it finds to Google using our spam complaint form. athttp://www.google.com/contact/spamreport.html. Ethical SEO firms report deceptive sites that violate Google's spam guidelines.

• Make sure you're protected legally.

Don't be afraid to request a refund if you're unsatisfied with your SEO's performance. Make sure you have a contract in writing that includes pricing. The contract should also require the SEO to stay within the guidelines recommended by each search engine for site inclusion.

What are the most common abuses a website owner is likely to encounter?

One common scam is the creation of "shadow" domains that funnel users to a site by using deceptive redirects. These shadow domains often will be owned by the SEO who claims to be working on a client's behalf. However, if the relationship sours, the SEO may point the domain to a different site, or even to a competitor's domain. If that happens, the client has paid to develop a competing site owned entirely by the SEO.

Another illicit practice is to place "doorway" pages loaded with keywords on the client's site somewhere. The SEO promises this will make the page more relevant for more queries. This is inherently false since individual pages are rarely relevant for a wide range of keywords. More insidious, however, is that these doorway pages often contain hidden links to the SEO's other clients as well. Such doorway pages drain away the link popularity of a site and route it to the SEO and its other clients, which may include sites with unsavory or illegal content.

What are some other things to look out for?

There are a few warning signs that you may be dealing with a rogue SEO. It's far from a comprehensive list, so if you have any doubts, you should trust your instincts. By all means, feel free to walk away if the SEO:

• owns shadow domains
• puts links to their other clients on doorway pages
• offers to sell keywords in the address bar
• doesn't distinguish between actual search results and ads that appear in search results
• guarantees ranking, but only on obscure, long keyword phrases you would get anyway
• operates with multiple aliases or falsified WHOIS info
• gets traffic from "fake" search engines, spyware, or scumware
• has had domains removed from Google's index or is not itself listed in Google

If you feel that you were deceived by an SEO in some way, you may want to report it.

一、选择服务器放在哪个区域 

对于Google而言,不同的区域,搜索结果的就不同.一些英文关键词, 你在中国用Google搜索,发现你网站的排名非产靠前,但是如果你在国外用Google, 你可能翻十页都找不到你的网站. 

我们做Google排名的排名效果不是让我们自己看的, 而是让我们的潜在客户看的. 所以服务器的区域选择应选择潜在客户群体所在的区域。

二、检查服务器的IP是否被Google处罚过

1、检查一下这台服务器上放了多少网站呢? 如何查呢？这里我们给你大家一个工具，可以很轻松的查出来有多少域名共同指向一个IP：（http://whois.webhosting.info/ip/） 
例如: 如果你要查219.235.226.75 这个IP你只要在IT地址栏入: 
http://whois.webhosting.info/219.235.226.75/
点击回车, 以后就可以看到这个有多少域名指向了这个IP

2、选择几个www.###.com然后你在Google中输入：site：www.###.com然后看一看Google收录了这个网站多少页面。如果发现Google还没有收录它，就多查几个，如果大部分都是没有被Google收录的话，那么很有可能这台服务器是被Google处罚过的。为了保险期间，最好别用。
一般而言，被google处罚的域名比较多，被Google处罚的服务器相对比较少！ 

三、服务器运行一定要稳定

四、选择好的域名,合理设计网站路径和文件名
   域名/路径/文件名的设计原则: 
   1、那就是要包含关键词。排英文关键词的话,你可以选择与关键词相关的域名.排中文关键词的话,可以用汉语拼音域名，中文网站别人用中文路径和文件名 
   2、静态的路径比动态的路径有利于排名 
   3、顶级域名比二级域名有路径排名(知名网站,权威网站的二级域名除外)  
   4、abc.web.com比www.web.com/abc/有排名优势  
   5、www.web.com/abc/比www.web.com/abc.html这样的路径有排名优势.  

五、合理设计网页标题与标签: 
标题和标签主要是指网页源代码中<head>与</head>中间的部分内容. 例如我们的网络营销策划网的首页的标题和标签如下: 

<TITLE>网页教学网</TITLE> 
<meta. name="description" content="网页，网页制作"> 
<meta. name="keywords" content="网页"> 
<META. http-equiv=Content-Type content="text/html; charset=gb2312">
<meta. http-equiv="Content-Language" content="zh-cn">

1、网页标题设计原则: 
a、每个网页的标题都要不同，并且要与自身网页的内容像符合；  
b、网页标题设计简介明了,每个页面的标题最好只终点突出1-2个关键词,不要太多； 
c、标题设计不要太长,最好不要超过25个汉字, 50个英文字母。  

2、网页描述标签的设计： 
网页描述标签，它主要是给搜索引擎看的，这个标签设计追求简单明了，与该网页内容相符合。为了提高排名，可以适当在里面提高关键词的密度。 

3、关键词标签的设计：
目前对Google已经没有什么作用了，不过对其他搜索引擎的排名还有一定的作用，这个标签的设计原则和是简介明了，如果是多个关键词，可以用英文逗号格开，无关的关键词最好别用，容易被一些搜索引擎当作左臂来处理。 

4、网页编码和语言注释标签设计：
主要是给浏览器看的。不同语言的编码都不同，所以做外文网站的时候一定要注意，最好用潜在客户使用的操作系统的编码，要不然潜在客户看到的网页将是乱码。如果你的网站是英文网站，你的潜在客户是针对西欧的，你可以用以下代码： <meta. http-equiv="Content-Type" content="text/html;charset=iso-8859-1">

六、提高PR值

PageRank 技术：通过对由超过 50,000 万个变量和 20 亿个词汇组成的方程进行计算，PageRank 能够对网页的重要性做出客观的评价。PageRank 并不计算直接链接的数量，而是将从网页 A 指向网页 B 的链接解释为由网页 A 对网页 B 所投的一票。这样，PageRank 会根据网页 B 所收到的投票数量来评估该页的重要性。 

PageRank 还会评估每个投票网页的重要性，因为某些网页的投票被认为具有较高的价值，这样，它所链接的网页就能获得较高的价值。重要网页获得的 PageRank（网页排名）较高，从而显示在搜索结果的顶部。Google 技术使用网上反馈的综合信息来确定某个网页的重要性。搜索结果没有人工干预或操纵，这也是为什么 Google 会成为一个广受用户信赖、不受付费排名影响且公正客观的信息来源。  

七、合理设计网站链接结构
    合理的网站链接结构有一下特点： 
1、拥有一个网站地图，网站地图链接向所有的网页，所有的网页上有一个链接指向网站地图页面；内容要小于100K。 
2、网站导航清晰明了，方便用户浏览； 
3、链接不用FLASH按钮和图片，而是使用文本。  

八、增加反向链接策略
1、查看反向链接：在搜索框中输入：link:www.webjx.com
2、增加网页的反向链接的方法： 
和相关网站进行链接交换  
到相关网站可以添加反向链接的网页上添加  
将网站加入到世界著名分类目录网站中  

3、选择链接网页的原则： 
   PR值非常高的页面  
   PR值不是太高，但是导出链接比较少的页面  
   权威网站的主要页面  

九、网站内容与网页设计 

优秀的网站内容主要包括以下一种： 

1、原创内容较多，容易被众多网站引用，引用的过程中一般都会给这个页面加有链接，所以这个页面可以获得较好的评分，排名自然会好； 

2、网站内容丰富：丰富的网站内容会让Google收录网站许多内容，网站各个页面之间的链接有利于其提高网站各个页面的在Google中的评分； 

3、网站结构清晰明了，页面设计合理，容易被用户浏览和被Google搜索引擎爬虫爬行； 

4、将asp转化成html，并且压缩减肥  每个页面不要大于100K, 导出链接要小于100个。

HTML格式的静态页面容易被搜索引擎收录，并且容易获得较好排名； 
HTML格式的静态页面比较节省你的服务器资源，不怕你网站人气增加的快； 
Html格式的静态页面不需要调用数据库、用户浏览起来速度非常快。 

   目前，大部分网站都采取用了新的技术，那就是后来是动态程序，前台是静态页面。虽然前台是html的，但是他们也可以通过后台来修改。 
   如果你的网站是商城系统或者其他的系统，很难断时间内改版，你还可以采取以下策略： 那就是通过技术手段把news.asp?id=234 这样的链接映射成 news/234.html 
   这个技术非常简单，你只需要在服务器上装一个 ISAPI REWRITE （Google888.com 有免费下载）、然后进行相应的参数设置就OK  

十、突出网页中的关键词： 

    1、大标题中要包含关键词：大标题是网页头部用<h1></h1>注释的网页标题； 
    2、<{#imeinline} style="LINE-HEIGHT: 150%" align="left">网页文本中的关键词要专门突出：可以用<B></B>来突出，也可以用醒目的颜色来突出； 
    3、合理调整页面的中关键词出现的频率，一般而言，关键词在网页中出现的频率保持在
3％－5％比较好。

十一、写好robots.txt文件

一个放在网站根目录下面给搜索引擎爬虫指路的文件，如果你一不小心写错了，有可能Google把你所有的网页都给删除掉了。关于这个文件内容的写法，Google网站有详细的说明：http://www.google.com/intl/zh-CN/remove.html 

十二、增加超链接注释 

title=”注释内容” 
不加注释的代码: 
<a href="http://www.webjx.com">网页教学网</a>  
加注释后的代码：: 
<a href=http://www.webjx.com title="网页教学网 - 提供最新最快的网页技术">网页教学网</a> 

图片注释标签:一般网页中插入一张图片在html的代码如下: 
<IMG height=70 width=187 src="images/webjx_logo.gif" >

可以将图片加上注释,如下: 
<IMG height=70 width=187 src="images/webjx_logo.gif" alt=”网页教学网”> 

ALT注释一定简介明了,千万不要写的太过冗长,这样会被一些搜索引擎当作作弊来对待的.
