Hello BHW members. Here is what I need to know.. I have a new client and his website is made on php. I have targeted different keywords according to pages. But the problem I am facing is.... The urls are like http://www.abc.com/location_project.php?city=1, http://www.abc.com/location_project.php?city=2 and so on. I told the developer that this kind of url will be difficult to rank with the names of the cities. I told him to change the permalink but he said it is not possible to change it. I just need to know if he is right and if there is any way to rename those urls please guide me.
