Canonical URLs Causing Duplicate Content

    Hello AJAX Load More Staff,

    In some SEO analyzing tools, the canonical link push states causes duplicate content issues. For example, /blog/ and /blog/page/2 canonical tags are the same but shown as two different pages. Is there a way to fix this in the plugin?

    Thank you,

    Hi @graphettion,
    Are you referring to the canonical URL in the <head>?

    Can you show me an example of where this is updated? Im assuming you feel the canonical URL should read /page/2/ ?

    Yeah, that’s what I’m referring to. I’m not the best at explaining. ?? I want /page/2, /page/3, etc canonical tags to be /blog.

    Ex:
    <link rel=”canonical” href=”https://example.com/blog/page/2&#8243; />

    Should be:
    <link rel=”canonical” href=”https://example.com/blog&#8221; />

    No worries, i figured it out ??
    I see what you mean, so you think the [plugin should update the <link /> tag when a pushstate or popstate happens?

    I checked a few sites that have standard paging and every time there was a paged URL the canonical URL was still the root url without the ‘/page/3/’ value.

    Can you show me an example of another WordPress site that updates this canonical <link /> tag while paging?

    I had the same problem. I solved it by redirecting (301 SEO friendly) the user/google-robot to the main-category page, and using Ajax Load More with unlimited posts argument (which is default setting as far as I remember).

    add_action( 'template_redirect', 'wpse27119_template_redirect' );
function wpse27119_template_redirect() {

    /* Redirect user to main category if the URL contains "/page/" */
    if ( strpos( $_SERVER['REQUEST_URI'], "/page/" ) !== false ) {
        global $wp_query;
        $category_id = $wp_query->get_queried_object()->term_id;
    
    	wp_redirect( get_category_link( $category_id ) );

    	return false;
    }
}

    wp_redirect( get_category_link( $category_id ) );

    should actually be:

    wp_redirect( get_category_link( $category_id ), '301' );

    Awesome. I’ll try it tomorrow. Thank you unicco. I appreciate both your speedy responses.

    The plugin is great by the way. Great job dcooney and the contributors.

    It worked like a charm. Much thanks unicco. I also added it for the /blog page.

    //Canonical Tags for AJAX Load More (Ex: /blog/page/2, /blog/page/3, all go to /blog)
add_action( 'template_redirect', 'wpse27119_template_redirect' );

function wpse27119_template_redirect() {
  /* Redirect user to main category if the URL contains "/page/" */
  if ( strpos( $_SERVER['REQUEST_URI'], "/page/" ) !== false ) {
    global $wp_query;
    $category_id = $wp_query->get_queried_object()->term_id;
    $blog_id = get_permalink(get_option( 'page_for_posts' ));

    wp_redirect( get_category_link( $category_id ), '301' );
    wp_redirect( $blog_id, '301' );

    return false;
  }
}

    Actually renamed $blog_id to $blog_url to give it a more meaningful name.

    Glad I could help.

    You might wanna put some conditional tags in your code, to separate the two redirections. Just a suggestion.

    For category you can use: if ( is_category() ) { }

    For blog-page you can use: if ( $wp_query->query['pagename'] == 'blog' ) { }

    I wish I fully understood what you guys are up to here!

    Care to explain it in a TL;DR format? ??

    Hey @dcooney, here’s a visual of what I’m talking about.

    This explains what I am wanting. Unicco helped me code it for both categories and blog now (which I am much appreciated).

    Let me know if this helps explain.

    @unicco: How does this look?

    function wpse27119_template_redirect() {
  /* Redirect user to main category if the URL contains "/page/" */
  if ( strpos( $_SERVER['REQUEST_URI'], "/page/" ) !== false ) {
      global $wp_query;
      $category_id = $wp_query->get_queried_object()->term_id;
      $page_name = $wp_query->query['pagename'];
      $blog_url = get_permalink(get_option( 'page_for_posts' ));

      if ( is_category() ) {
        wp_redirect( get_category_link( $category_id ), '301' );
      }

      if ( $page_name == 'blog' ) {
        wp_redirect( $blog_url, '301' );
      }

  	return false;
  }
}

    @dcooney, does that make sense?
