Микроразметка Schema.org - Breadcrumb - Product (CMS Opencart)

Если Google ругается на position в https://schema.org/BreadcrumbList
"Необходимо указать значение для поля position."

Решение проблемы:

<ul class="breadcrumb" itemscope itemtype="https://schema.org/BreadcrumbList">
<?php foreach ($breadcrumbs as $i=> $breadcrumb) { ?>
	<?php if($i+1<count($breadcrumbs)){ ?>
		<li itemprop="itemListElement" itemscope itemtype="https://schema.org/ListItem">
			<a itemprop="item" href="<?php echo $breadcrumb['href']; ?>">
				<span itemprop="name"><?php echo $breadcrumb['text']; ?></span>
			</a>
			<span class="breadcrumb-next">&gt;</span>
			<meta itemprop="position" content="<?php echo $i+1; ?>" />
			<link itemprop="url" href="<?php echo $breadcrumb['href']; ?>" />
		</li>
	<?php } else { ?>
		<li itemprop="itemListElement" itemscope itemtype="https://schema.org/ListItem">
			<span><?php echo $breadcrumb['text']; ?></span>
			<link itemprop="item" href="<?php echo $breadcrumb['href']; ?>">
			<meta itemprop="name" content="<?php echo $breadcrumb['text']; ?>">
			<meta itemprop="position" content="<?php echo $i+1; ?>" />
			<link itemprop="url" href="<?php echo $breadcrumb['href']; ?>" />
		</li>
	<?php } ?>
<?php } ?>
</ul>

Если Google ругается на position в https://schema.org/Product
"Необходимо указать значение для поля position."

Убирайте из карточки продукта все схемы связанные с itemtype="http://schema.org/ItemList" и  itemprop="itemListElement"

Мой вариант кода страницы Категория:

<?php foreach ($products as $product) { ?>
<div class="col-sm-3">
<div class="cat-item" itemtype="https://schema.org/Product" itemscope>
<noindex>
	<div class="cat-item-opcii">
		<?php if ($product['options']) { ?>
		<!-- опции-->
		<?php } ?>
	</div>
</noindex>
	<div class="image">
		<a href="<?php echo $product['href']; ?>">
			<img itemprop="image" src="<?php echo $product['thumb']; ?>" alt="<?php echo $product['name']; ?>" title= <?php echo $product['name']; ?>" class="img-responsive" />
		</a>
	</div>
	<?php if ($product['price']) { ?>
				<?php if (!$product['special']) { ?>
					<div class="cat-item-price" itemscope itemprop="offers" itemtype="https://schema.org/Offer">
						<span class="price_no_format<?php echo $product['product_id']; ?>0" price="<?php echo $product['price_no_format']; ?>"><?php echo rtrim($product['price'], '.'); ?></span><span class="one-price-r"> руб.</span>

</noindex>
</div>
</div>
<?php } ?>
