Bitrix. Add <link rel="canonical"

Adding a canonical link through the settings of the complex component directory

If you have a standard component and template, then most likely you just need to add a parameter to the component call:

$APPLICATION->IncludeComponent(
	'bitrix:catalog',
	'catalog',
	[
		...
		'DETAIL_SET_CANONICAL_URL'=> 'Y'
		...
	]
);

Add rel canonical to header.php

Alternatively, a canonical link can be added by cutting off all unnecessary from the url

$page = $APPLICATION->GetCurPage(true);
if (preg_match('/^\/catalog/', $curPage))
    echo '<link rel="canonical" href="' . page . '" />';

or

<link rel="canonical" href="<?=$APPLICATION->GetCurDir(); ?>" />

Adding a canonical link via catalog component templates

In the result_modifier.php file of the catalog.section component, add at the very bottom:

$arSection = CIblockSection::GetById($arResult["ID"])->GetNext();
$arResult['SECTION_PAGE_URL'] = $arSection['SECTION_PAGE_URL'];

$cp = $this->__component; 
if (is_object($cp))
	$cp->SetResultCacheKeys(array('SECTION_PAGE_URL'));

Add to the component_epilog.php file

$APPLICATION->AddHeadString('<link href="https://'.SITE_SERVER_NAME.$arResult['SECTION_PAGE_URL'].'" rel="canonical" />',true);

In the component template catalog.element , proceed in a similar way. Add

$arElement = CIblockElement::GetById($arResult["ID"])->GetNext();
$arResult['DETAIL_PAGE_URL'] = $arElement['DETAIL_PAGE_URL'];
$cp = $this->__component; 

if (is_object($cp))
	$cp->SetResultCacheKeys(array('DETAIL_PAGE_URL'));

In component_epilog.php add

$APPLICATION->AddHeadString('<link href="https://'.SITE_SERVER_NAME.$arResult['DETAIL_PAGE_URL'].'" rel="canonical" />',true);
