What are the potential drawbacks of using AJAX in PHP for loading content?

One potential drawback of using AJAX in PHP for loading content is the issue of search engine optimization (SEO). Since search engine crawlers may not execute JavaScript, content loaded via AJAX may not be indexed properly, leading to potential SEO issues. To solve this problem, you can implement server-side rendering of the content being loaded via AJAX to ensure that search engines can properly crawl and index it. 

<?php
// Server-side rendering of content for AJAX loading
if(isset($_GET['ajax_request'])) {
    // Your code to fetch and render the content
    echo "Content loaded via AJAX";
    exit;
}
?>
