Are dynamic pages not read by search engine robots?

Dynamic pages can be read by search engine robots, but there are certain factors that can affect their visibility. Search engine robots may have difficulty crawling dynamic pages that have complex URLs or parameters. To improve the visibility of dynamic pages, it is recommended to use search engine-friendly URLs, implement proper meta tags, and create an XML sitemap. Additionally, submitting the dynamic URLs to search engines through their webmaster tools can also help improve indexing.

// Example of creating search engine-friendly URLs in PHP
if(isset($_GET['page'])) {
    $page = $_GET['page'];
    switch($page) {
        case 'home':
            include('home.php');
            break;
        case 'about':
            include('about.php');
            break;
        // Add more cases for other dynamic pages
        default:
            include('404.php');
            break;
    }
} else {
    include('home.php');
}
