How does a question mark affect the URL for Google? Is this URL "Clean"?

[RP_Joe]

I have seen a CMS that is making the following url: http://www.abc.com/index.php?page=database_websites .

Is this a problem? Is it clean enough? Will it cause confusion?

Not sure the brand of CMS.

There is no problem with that URL in itself. Google does index the query string that follows a question mark as long as there are not a lot of variables. This example has only one variable (there is no ampersand [&] in other words).

However, other problems may come depending on how the server is configured to deal with that query string. For example, if you can change the query straing and still get the same content, then you have a potential duplicate problem waiting.
