Misspelled domain names. How to tell Google the right one.

In case you choose a domain name, that can be misspelled, or you registered different top-levels of the domain, you should redirect the alternatives to the “right” address. Even the use of “www” or not, maybe important for you. And also have in mind, that kpi-agent.com and www.kpi-agent.com are two different domains in the eyes of search-engines and will most likely be seen as duplicate content.

For this website:
I want the people to use my blog-domain without “www.” and also the different alternatives (kpiagent.com|kpi-agent.de|kpiagent.de) should be redirected to kpi-agent.com. How to do that? With some URL rewriting, using a “.htaccess” file. If you already have one in your main web-directory (assuming you use an apache-webserver) just add the last two lines, directly under “RewriteEngine On”, or make a new one with this content (changed to your needs):

## use mod_rewrite
RewriteEngine On

## Force usage of kpi-agent.com
RewriteCond %{HTTP_HOST} !^kpi-agent.com$
RewriteRule ^(.*) http://kpi-agent.com/$1 [R=301,L]

The web-server sends a 301 status-code to the browser, means “Moved Permanently”, that even tells Google and other search-engines, to only only that URL for indexing.

BE CAREFUL:
If you already have external-links coming from different plattforms, you should be careful with this action, since this maybe destroys the PageRank relevance. In that case, if possible, try to contact the important websites to change the URL to your page, first!
