Force google to just index rewrited urls

Question

Let's think we have a website with a URL like http://www.domain.com/webdesign/ that rewrites http://www.domain.com/?article=1.

now when i search my keyword in Google, it will show up http://www.domain.com/?article=1 in search results, while there is no link to that in any page and all menus are linked to http://www.domain.com/webdesign/ and i want that to be index.

Is there anyway to solve this?

Answer 1

Use canonical URLs or 301 redirects.

Canonical URL:

<link rel="canonical" href="http://www.domain.com/webdesign/" />

That will tell Google to use that URL in its search results.
