How does mod_rewrite play a role in addressing the challenges faced by PHP CMS systems with search engine bots?

PHP CMS systems often have dynamic URLs that can be difficult for search engine bots to crawl and index effectively. Mod_rewrite can help address this issue by allowing developers to create search engine-friendly URLs that are easier for bots to understand and navigate. By using mod_rewrite, developers can rewrite complex URLs into simpler, more descriptive ones that are more likely to be indexed by search engines.

RewriteEngine On
RewriteRule ^blog/([a-zA-Z0-9-]+)$ /index.php?page=blog&slug=$1 [L]
