Search engine optimization (SEO) is an essential aspect of any website, especially when it comes to WordPress. One of the most popular SEO plugins for WordPress by far is the Yoast SEO plugin, which has been around since 2008 and downloaded over 5 million times.

Yoast SEO is a powerful tool that helps developers optimize their WordPress sites for search engines. It is free, easy to configure, and offers a range of features that can help improve the visibility of a website.

Potential Conflicts with Yoast and Custom Applications

Despite the many benefits of the Yoast SEO plugin, it can sometimes get in the way of custom applications. This is because the plugin can override the page meta information and elements that are added by other PHP scripts.

For example, if a custom PHP script is used to add a dynamic meta title and description to a page based on a GET variable, Yoast SEO may override existing functions with its own meta information. This results in different content presentations having the same title and description, which can harm the website’s SEO.

Override Yoast SEO Metadata using PHP

To prevent Yoast from getting in the way of your custom scripts, ensure you are using the correct WordPress Filters in your code:

// Custom Selection Title with Yoast SEO Plugin
add_filter('wpseo_opengraph_title','filter_yoast_wpseo_title', 999);
add_filter('wpseo_title', 'filter_yoast_wpseo_title');
function filter_yoast_wpseo_title($title)
{
    $title = "YOUR_CUSTOM_PAGE_TITLE";
    return $title;
}

// Custom Seleection Desc with Yoast SEO Plugin
add_filter('wpseo_opengraph_desc','filter_yoast_wpseo_desc', 999);
add_filter('wpseo_metadesc', 'filter_yoast_wpseo_desc');
function filter_yoast_wpseo_desc($desc)
{
    $desc = "YOUR_CUSTOM_PAGE_DESC";
    return $desc;
}

You can place this script on any custom PHP template, just before calling the wp_head() function. This will ensure that your custom metadata is the last script to run prior to generating the HTML head tags.
