WordPress: How To 301 Redirect Pagination Pages To The Father or mother URL


It might be anecdotal, however I’m discovering that Google Search Console is changing into extra complete in its reporting. A lot in order that I’ve begun to lean on it an increasing number of… particularly to establish pages not discovered on the positioning that may negatively affect search rankings.

My website’s theme incorporates an strategy the place guests can click on load extra in the event that they’d wish to see further posts for the house web page, class archives, tag archives, and even search outcomes. This consumer expertise (UX) enhancement does away with pagination, the place a consumer (or search crawler) would iterate by means of pages and weblog publish outcomes.

Nevertheless, regardless of enabling this performance on my website, Google nonetheless believes that I’ve pagination and that there are errors on the positioning the place these pages are now not discovered. If I went to a type of pages listed in Google Search Console, it resulted in a 404. Google believes there’s an issue with my website when there isn’t.

To treatment this, I wanted to construct a customized redirect in my youngster theme capabilities.php that takes any of these /pages/# and redirects them to their mum or dad. One exception that I wanted was my customized publish sort for my acronyms.

At the moment, I pushed this enhancement to my youngster theme which accommodates any of the situations above:

  • /web page/{quantity} – My house web page is my weblog archive, so this is able to lead to a 404 with my load extra function. Now any web page will redirect to my house web page.
  • /tag/{tag-slug}/web page/{quantity} – My tag pages would lead to a 404 with my load function. Now any web page will redirect to mum or dad /tag/{tag-slug}/
  • /class/{category-slug}/web page/{quantity} – My class pages would lead to a 404 with my load function. Now any class web page will redirect to mum or dad /class/{category-slug}/
  • /{category-slug}/web page/{quantity} – My class pages strip out /class/ and would lead to a 404 with my load function. Now any class web page will redirect to mum or dad /{category-slug}/

Nevertheless, my acronym pages are nonetheless indexable:

  • /acronym/web page/{quantity} nonetheless exists and might be crawled and listed.

Baby Theme Code

add_action('init', 'custom_redirect_with_exceptions');
perform custom_redirect_with_exceptions() {
    // Common expression to match paths ending with /web page/quantity
    if (preg_match('/^(/[^/]+)/web page/d+/', $_SERVER['REQUEST_URI'], $matches)) {
        $base_path = $matches[1]; // Seize the bottom path
        
        // Listing of base paths to exclude from redirection (e.g., customized publish sorts)
        $exclusions = ['/acronyms']; // Exchange together with your precise base paths

        // Verify if the bottom path shouldn't be within the exclusions checklist
        if (!in_array($base_path, $exclusions)) {
            // Verify for tag or normal slug
            if (preg_match('/^/tag/', $_SERVER['REQUEST_URI'])) {
                // Particular logic for tag redirection: take away '/tag' prefix
                $redirect_base = str_replace('/tag', '', $base_path);
            } else {
                // Normal slug logic: use the bottom path as is
                $redirect_base = $base_path;
            }
            
            // Assemble the brand new URL to redirect to the bottom path with out pagination
            $new_url = home_url($redirect_base);
            
            // Redirect to the brand new URL with a 301 everlasting redirect standing
            wp_redirect($new_url, 301);
            exit;
        }
        // No motion is taken if the URL is within the exclusions checklist
    }
    // Verify if the URL is only a paginated house URL
    else if (preg_match('/^/web page/d+/', $_SERVER['REQUEST_URI'])) {
        // Redirect paginated house URLs to the house web page
        wp_redirect(home_url("https://martech.zone/"), 301);
        exit;
    }
}

The code first checks if the URL matches a paginated format excluding specified paths. If it does, and it’s not an excluded path, it redirects to a non-paginated model of that path. If the URL is a paginated house URL, it redirects to the house web page. Clarification:

If it does, the bottom path is captured and saved in $matches[1].
  • $base_path = $matches[1];: Shops the captured base path from the URL into the variable $base_path.
  • $exclusions = ['/acronyms'];: Defines an array of base paths that shouldn’t be redirected in the event that they match the present URL’s base path.
  • if (!in_array($base_path, $exclusions)) { ... }: Checks if the captured base path shouldn’t be within the checklist of exclusions.
    • Inside this conditional:
    • if (preg_match('/^/tag/', $_SERVER['REQUEST_URI'])) { ... }: Determines if the URL begins with /tag/, indicating it’s a tag URL.
      • If true: $redirect_base = str_replace('/tag', '', $base_path);: Removes /tag from the bottom path, getting ready it for redirection to the tag’s major web page.
      • Else: $redirect_base = $base_path;: If it’s not a tag URL, makes use of the bottom path as is for redirection.
    • $new_url = home_url($redirect_base);: Constructs the brand new URL to redirect to, eradicating the pagination however preserving the bottom path.
    • wp_redirect($new_url, 301);: Redirects the consumer to the constructed URL with a 301 (Moved Completely) standing code.
    • exit;: Stops additional processing to make sure the redirection takes impact instantly.
  • else if (preg_match('/^/web page/d+/', $_SERVER['REQUEST_URI'])) { ... }: Checks if the URL is a paginated house URL format, like /web page/2.

    • wp_redirect(home_url("https://martech.zone/"), 301);: Redirects paginated house URLs again to the house web page.
    • exit;: Stops additional processing, guaranteeing the redirection is executed.
