Welcome to the Q&A Forum

I know you posted this a while ago, but I've just seen it. The simplest way would be to generate your ROBOTS meta tag based on the parameter. I code in PHP so this is my example, but it will depend on your platform Say your URL is domain.com?lang=es or ?lang=po or ?lang=de $lang = $_GET['lang']; if($lang=="de"){ echo ''; } else{ echo ''; } I left 'follow' in the German line because you may already have pages in the index, so this means Google DE has free reign over all your site, but any pages it finds should not be indexed. If the site's not live yet, then you can change the 'follow' in the DE line to 'nofollow'. Hope this helps.

There's a company called FutureSimple that does a good job of this in my opinion. Take a look at their pages for these two keywords: "Online CRM Software" - http://bit.ly/xK3KZQ "Web Based CRM Software" - http://bit.ly/yZaAow That is a good way to handle two slightly different keywords, that mean the same thing, but both have enough search traffic and competition that you have to target both of them individually. You'll note that they use a very similar page structure, but the images are different, and all of the text is different. If you use that method and all text and images are completely custom, then yes, I would create separate pages with unique URLs for each of those keywords that are fairly difficult. For keywords that are more similar, such as "send money to Cina from the US" and "send money to China from the United States", then no, I would not create multiple pages. Use the method above for synonym terms with lots of traffic going to each keyword.
