Redirects and seo

[realestate]

How many types of redirects are there?

framed
standard
301

Any others? What are the seo effects of these? Does google show PR of destination or original domain?
My experience is that redirected domain loses PR quickly.

[John Scott]

301 redirects pass PR transparently. Usually, if a domain is redirecting to another domain, both have the same PR. A while back, for example, I temporarily removed the bluefind.net > bluefind.com redirect. BlueFind.net had PR8, even though it has no links of its own.

you also can use 301 redirects and meta redirects to help pass penalties onto other sites

301 redirects will start getting abused more and search engines will soon selectively discount some of them in some way (they may already be doing it)

Is a mod rewrite treated by searchengines as a 301 redirect?

It depends what status code you return.

Good stuff here http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

This is a good tool for viewing what status code is returned http://www.rexswain.com/httpview.html

NFFC, Thanks very much for the information.

a stupid question... what is a 301 redirect??

[MarketingLady]

A 301-Redirect tells the visitor (Spider or human User) that this URL has permanently moved to another URL; e.g: if you want to redirect urlnumber1.com to www.urlnumber2.net, you will do this with a "301-Redirect" (= Status permanently moved).Syntax:

Redirect permanent urlnumber1.com/ http://www.urlnumber2.net/
or
Redirect 301 urlnumber1.com/ http://www.urlnumber2.net/

This kind of redirect passes PR and some other properties (negative ones too) from urlnumber1.com to www.urlnumber2.net.

301 redirects will start getting abused more and search engines will soon selectively discount some of them in some way

Let's hope major search engines can fix this bug during next time; though Google's 302-Bug isn't fixed at all, it is still possible to hijack nearly every "weaker" site.

marketing lady, thank you very much for your explanation.
now i know something new!

Oh, there is something important to add: on Google.de, Google has sometimes (!!!) problems with www.mydomain.com vs. mydomain.com; it seems sometimes Google treats the same domain without www as duplicate ;-). It is ridiculous but it is true.
When starting a new project, eg www.mydomain.com I recommend to put the following code snippet into your .htaccess

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.mydomain\.com$
RewriteRule ^(.*)$ http://www.mydomain.com/$1 [L,R=301]
