Thanks a lot for the quick answer!
Answer to my question:
There is nothing wrong with this, and is how most CMS’s do things. The one negative here from a Google point of view is the URL used to portray each different page. For instance, index.php?cat=review&type=casino&name=slotland is not as good as /review/casino/slotland. The only way i know of to get around this is by using mod rewrite on a linux server.
Followup:
So what you are saying is that it would be better to create each review as a different html-file, rather than having one review.php?id=1919 that generates each review based on the ID?
Of course this will be a lot more difficult to maintain and a lot more work to create, but if it is worth the effort I will most likely do it.
Another question
About the php-include which is also serverbased, if you open the .php file in notepad it will say something like but on serverside it enters the whole code for 123.php. Will this have an affect on google too?
