I would be very interested in seeing the Perl approach to pretty URLs
As fas as the SEO benefits of pretty URLs that topic has already been discussed many times.
i.e. a good place to start is All You Need To Know About SEO
The PERL Approach is used instead of using a mapping text file, you query the database to get the mappings. This saves having to add a reference in a text file with every new ID. That’s what it said
The URL you post mentions nothing about what I said above. I know static URLS are better than Dynamic but what I was looking for was a definitive answer like, it’s not going to make that much difference or it will make a huge difference.
