Show Homepage (only) Hits Count

Add the counter (PHP or otherwise) to the template file for the home page. This will be either home.php or index.php depending on how you have things set up.

If you want to instead add it in the footer, enclose the code inside a conditional tag to detect whether or not you’re on the home page:

if( is_front_page() ) {
    // ... put your tracking code here.
}
