What are the implications of using "echo" in PHP for search engine visibility?

Using "echo" in PHP to output content directly can hinder search engine visibility because search engines may not be able to properly crawl and index the content. To improve search engine visibility, it is recommended to use HTML markup and semantic tags to structure the content for better indexing. 

<?php
// Instead of using echo to output content directly, use HTML markup and semantic tags
echo "<h1>Title</h1>";
echo "<p>Content</p>";
?>
