What are the potential drawbacks of using parameterized URLs in PHP for SEO purposes?

Using parameterized URLs in PHP for SEO purposes can potentially create duplicate content issues since search engines may treat different URLs with the same content as separate pages. To solve this issue, you can implement URL rewriting to create SEO-friendly URLs that do not contain parameters.
