多个域名
我有一位客户已经上网有一段时间了。 他们购买了一个描述其产品的域名，以及第二个更新的域名。 现在该公司已经发展到更通用的水平，并购买了第三个域名 - 例如：
- vegetables.com (2005)
- ecolo-vegetables.com (2006)
- good-health-eating.com (2009)
以下是我的问题：
- 什么是让所有这些域名都以新名称命名的最佳方法是什么？
- 新名称对于搜索引擎和其他链接器来说是未知的，我不想失去排名，那么保持排名的最佳方法是什么？
- 我可以将 URL 指向排名“最佳”的域吗？
- 反向链接器附加了什么？ 他们链接到哪个域？
- 新域名的名称中有一个“-”...这对 SEO 确实有好处，但输入起来有点不自然，我也应该获得无破折号版本吗？
nb 将所有域名重定向到同一个域名下是有意义的，但是您会选择最旧的（带有 modrewrite ）还是最新但没有生命的域名（因此它不存在于搜索引擎中的任何地方）
另一个 ps 有些人会告诉我用 .htaccess 重定向，但我应该更改 dns 以指向最后一个 .com。 哪种解决方案更好
I have a customer that been on the web for some time. They have bought a domain name that describe it product, and a second one more up to date. Now that company has evolved to something more general and has bought a 3rd domain - something like:
- vegetables.com (2005)
- ecolo-vegetables.com (2006)
- good-health-eating.com (2009)
Here are my questions:
- What is the bet way to get all those domains under the new name?
- The new name is unknown to search engine and other linker, I don't want to lose the ranking, so what is the best way to keep that ranking?
- Can I point URLs to the "best" ranked domain?
- What append to the backlinker? they link to which domain?
- The new domain has a "-" in the name... which is really good to SEO but a little unnatural to type, should I get the no dash version too?
n.b. It make sense to redirect all the domain under the same, but will you choose the oldest (with modrewrite) or the newest but with no life under it's belt (so it doesn't exist anywhere in search engine)
another p.s. Some will tell me to redirect with .htaccess, but should I change the dns to point to the last .com. which solution is better

所有三个网站都“不同”还是指向相同的网站/内容？
Are all three sites "Different" or do they point to the same website/content?
我会尝试一下。
1. 您可能会进行重定向或仅允许域的 DNS 指向新的（所需的）网站。
2. 现在理解 SEO（搜索引擎优化）并不难 - 确保您拥有正确的元标记和其他 SE 信息将为您提供很大的帮助。 没有任何方法可以转移 SE 等级。
3.这是可能的。 您可以将 ABCDEF.COM 在 google 上排在第 3 位，然后将 ABCDEF.COM 设置为重定向到 GHIJKL.COM。
4.如果您设置了重定向，并且新网站与旧网站具有相同的内容，则可以设置您的 DNS 和重定向以重定向到上一页的新版本在新网站上。
（我认为我的措辞不太好，希望您明白我的意思）
5.出于纯粹的经验，我会说是的，两者都得到。 这样，您就可以以 ABCDEF.com 的形式向客户受众进行营销，但以 AB-CD-EF.COM 的形式向 SE 展示。
I'll give this a go.
1. You could possibly have redirects or just allow the DNS of the domain to point to the new (desired) website.
2. It's not hard to understand SEO (Search Engine Optimization) nowadays - ensuring you have the correct meta tags and other SE info will give you a big helping hand. There isn't any way of transferring SE ranks.
3. That's possible. You could have ABCDEF.COM at number 3 on google, but then set ABCDEF.COM to redirect to GHIJKL.COM.
4. If you set up redirects, and the new site has the same content as the old one, there is the possiblity of setting up your DNS and your redirect to redirect to the new version of the previous page on the new website.
( I don't think I worded that very well, hope you catch my drift )
5. Out of pure experience I'd say yes, get both. That way you can market to your customer audience as ABCDEF.com, but show to SEs as AB-CD-EF.COM.
这是我从此链接得到的最佳答案
最后一句话：来自此链接确认一下我所知道的！
首先，确保您使用的是“301 重定向”而不是“302 重定向”，否则链接权重 (PageRank) 将不会转移到目标 URL。 您可以使用像这样的“服务器标头检查器”来验证 301（而不是 302）是否到位。 只有 301 告诉引擎以前的 URL 已永久移动，从而将页面的链接资产转发到新位置。
Here is the best answer i got from this link
And the last word : from this link that just confirm what i know know !
First off, ensure you're using "301 redirects" rather than "302 redirects" or the link juice (PageRank) won't transfer to the destination URL. You can verify that 301s (not 302s) are in place by using a "server header checker" like this one. Only a 301 tells engines the previous URL has moved permanently and thus forwards the page's link equity to the new location.
