Seeking advice: Dynamic sitemaps for better Laravel SEO

Hey everyone,

I'm quite new to the world of Laravel SEO and just launched my first small SaaS app built with Laravel. It's been an exciting journey, but I've hit a bit of a wall with sitemaps.

Currently, I've been managing a basic static sitemap, but as my content grows and updates regularly, it's becoming a real hassle to keep it current. I've heard dynamic XML sitemaps are the way to go, especially for auto-updating content, but I'm a bit lost on the practical implementation for someone new to advanced SEO techniques in Laravel. What's the best approach to implementing a truly dynamic XML sitemap that auto-updates? What are the key considerations to ensure it actually boosts search engine visibility and doesn't cause issues? I'm particularly interested in best practices for laravel seo optimization using this method.

I'm imagining something like this for configuration, but I'm unsure if I'm on the right track or if there are common beginner mistakes to avoid:

// config/sitemap.php (dummy example)
return [
    'models' => [
        App\Models\Post::class => [
            'frequency' => 'daily',
            'priority' => 0.8,
            'url_generator' => function ($post) {
                return route('posts.show', $post);
            },
        ],
        // ... other models
    ],
    'cache_duration' => 60, // minutes
];

Any advice from experienced Laravel SEO pros would be incredibly helpful for a newbie like me!
