Query string parameters in canonical URLs, and First H2 in meta titles

Hello @oneray

Thank you for contacting the support.

1. You can use the following filter and add the query string manually to the canonical URLs

add_filter( 'rank_math/frontend/canonical', function( $url ) {
    return $url . '?' . $_SERVER['QUERY_STRING'];
});

2. You can use the rank_math/frontend/title filter to add any information you want to the titles.

Hope that helps. If you have any further question(s), please let us know.

Hello,
well, I’m new to all this stuff, how and where exactly should I add these ?!

please do consider adding a simple checkbox to enable or disable canonical URLs..

Thanks.

An option for enabling or disabling canonical URLs on individual pages or posts will be helpful.

I just want to disable canonical URL on this page only.

Hello @oneray

Please add the code in your theme’s functions.php file.

Since we are keeping the plugin simple and easy to use, especially to the new users, we are not sure if an option will be added for it in the plugin.

However, you can easily change the output and disable the canonical URLs by using a filter.

Looking forward to helping you. Thank you.

it worked.. however, another problem appeared now..!!
this filter is adding a question mark “?” after all posts and pages canonical URLs, even in the homepage, check these for example:

https://www.online-ebook-download.com/blog
https://www.online-ebook-download.com/blog/free-ebooks
https://www.online-ebook-download.com/blog/salehoo-wholesale-suppliers-for-ebay

if this helps, here are the 2 parameters that are stripped out of the canonical URL (before adding your filter) >>
cs_category and cs_keywords

for “cs_category” parameter, each one of these “category” full links should be included in each page’s canonical >>
/shop?cs_category=1
/shop?cs_category=2
/shop?cs_category=3
etc..

and for “cs_keywords” parameter, each one of these “search keyword” links should be included in each page’s canonical >>
/shop?cs_keywords=health
/shop?cs_keywords=design
or whatever search term..

Thanks a lot for the help..

Hello @oneray

Can you please try with the following code?
Please tell him to use below code to change canonical URL:

add_filter( 'rank_math/frontend/canonical', function( $url ) {
	if ( is_page( 'PAGE_ID' ) ) {
		return''; // Remove Canonical URL. Replace PAGE_ID with the ID of the page you want to remove canonical.
	}

 if ( ! empty( $_SERVER['QUERY_STRING'] ) ) {
		$url = $url . '?' . $_SERVER['QUERY_STRING'];
  }
	return $url;
});

Hope that helps. Thank you.

1) Great, it works now.

2) concerning adding the first H2 in the meta title (just before the already added title) for this same page >> /shop , for dynamically created content >>
https://www.online-ebook-download.com/blog/shop?cs_category=251

including all the categories (more than 200) within it:
/shop?cs_category=1
/shop?cs_category=2
/shop?cs_category=3
etc..

is there a way to do this ??!

to prevent duplicate titles for 200+ category pages, is it worth it from SEO perspective ?
will it be server intensive? no load on the server ?!

Hello @oneray

Can you please try with the following filter?

add_filter( 'rank_math/frontend/title', function( $title ) {
    if ( ! is_page( 'PAGE_ID' ) || ! isset( $_GET['cs_category'] ) ) {
        return $title;
    }

    $term = get_term_by( 'id', $_GET['cs_category'] );
    if ( is_wp_error( $term ) || empty( $term ) {
        return $title;
    }
    
    return $term->name . ' - ' . $title;
});

Hope that helps. Thank you.

Not working !! it gave site-wide error >>
Parse error: syntax error, unexpected ‘{‘ in /…../blog/wp-includes/functions.php on line 6131

should I replace anything here? I just pasted this exact code (except PAGE_ID)..

Hello @oneray

Please try with the following code:

add_filter( 'rank_math/frontend/title', function( $title ) {
    if ( ! is_page( 'PAGE_ID' ) || ! isset( $_GET['cs_category'] ) ) {
        return $title;
    }

    $term = get_term_by( 'id', $_GET['cs_category'], 'product_cat' );

    if ( is_wp_error( $term ) || empty( $term ) ) {
        return $title;
    }

    return $term->name . ' - ' . $title;
});

Please stay advised that product_cat is a taxonomy name. If you are using a different taxonomy, then please tell change the name accordingly.

Hope that helps. Thank you.
