Hello all,
Greeting....

I have just got an SEO assignment for a 4 yrs old website. It's got PR in home as well as inner pages. Also some pages are appearing in Google Search Results for targeted keywords.

Now the problem is I have to make all inner page urls seo friendly. At this moment page urls look like domain.com/index.php?option=com_content&view=article&id=6:products-repair&catid=4:demo-category&Itemid=12.

My question is,
Is it possible to change the urls keeping the PageRank and Ranking as it is for all the pages?

I shall be thankful if you add your valuable comments on the same.

Thanks
Sunny
