我在为客户开发的网站上收到了一些 SEO 反馈。

基本上,该网站同时索引 http 和 https 页面。

我在后端打开了规范标签。为了消除重复,我们建议我们删除引用 https 页面的规范标签,并将其替换为相应的 http 规范标签。

这是 Magento 的内置功能,还是我必须创建自己的模块,检查页面请求类型并以这种方式插入标签?

因为我只是扩展 Mage_Catalog_Block_category_View 我只需要 _prepareLayout 功能。我的代码如下

protected function _prepareLayout()
{
parent::_prepareLayout();

$this->getLayout()->createBlock('catalog/breadcrumbs');

if ($headBlock = $this->getLayout()->getBlock('head')) {
  $category = $this->getCurrentCategory();
  if ($title = $category->getMetaTitle()) {
    $headBlock->setTitle($title);
  }
  if ($description = $category->getMetaDescription()) {
    $headBlock->setDescription($description);
  }
  if ($keywords = $category->getMetaKeywords()) {
    $headBlock->setKeywords($keywords);
  }
  if ($this->helper('catalog/category')->canUseCanonicalTag()) {
    if(isset($_SERVER['HTTPS'])) {
      $pattern        = '/((ht){1}(tps://))/';
      $replacement    = 'http://';
      preg_replace($pattern, $replacement, $category->getUrl());
      $headBlock->addLinkRel('canonical', $category->getUrl());
    } else {
      $headBlock->addLinkRel('canonical', $category->getUrl());
    }
  }
  /*
  want to show rss feed in the url
  */
  if ($this->IsRssCatalogEnable() && $this->IsTopCategory()) {
      $title = $this->helper('rss')->__('%s RSS Feed',$this->getCurrentCategory()->getName());
      $headBlock->addItem('rss', $this->getRssLink(), 'title="'.$title.'"');
  }
}

return $this;
}

默认情况下,Canonical 标签仍应为 http,尽管您的浏览器的地址栏是 https。

要对此进行测试,请在浏览器的地址栏中输入 https 和 http 版本,然后查看每个版本的页面源并在标题部分搜索规范标签(href 值)。它们应该相同,而不是 https。

如果您有问题,请告诉我您使用的是什么版本的 magento。

扩展块做

<?xml version="1.0"?>
<config>
    <modules>
        <RWS_ProductCanonical>
            <version>0.1.0</version>
        </RWS_ProductCanonical>
    </modules>

    <global>
        <blocks>
            <productcanonical>
                <class>RWS_ProductCanonical_Block</class>
            </productcanonical>
            <catalog>
                <rewrite>
                    <category_view>RWS_ProductCanonical_Block_Category_View</category_view>
                </rewrite>
            </catalog>
        </blocks> 
        <helpers>
            <productcanonical>
                <class>RWS_ProductCanonical_Helper</class>
            </productcanonical>
        </helpers>
    </global>
</config>

创建块 app/code/local/RWS/ProductCanonical/Block/Category/View.php (我扩展了 Mage_Core_Block_Template 并复制了所有代码,因为在扩展 Mage_Catalog_Block_Category_View 时,它向标题添加了多个标签)

class RWS_ProductCanonical_Block_Category_View extends Mage_Core_Block_Template
{
    protected function _prepareLayout()
    {
        parent::_prepareLayout();

        $this->getLayout()->createBlock('catalog/breadcrumbs');

        if ($headBlock = $this->getLayout()->getBlock('head')) {
            $category = $this->getCurrentCategory();
            if ($title = $category->getMetaTitle()) {
                $headBlock->setTitle($title);
            }
            if ($description = $category->getMetaDescription()) {
                $headBlock->setDescription($description);
            }
            if ($keywords = $category->getMetaKeywords()) {
                $headBlock->setKeywords($keywords);
            }
            if ($this->helper('catalog/category')->canUseCanonicalTag()) {
                ////// add to header here
                $headBlock->addLinkRel('canonical', $category->getUrl() . '?limit=all');
            }
            /*
            want to show rss feed in the url
            */
            if ($this->IsRssCatalogEnable() && $this->IsTopCategory()) {
                $title = $this->helper('rss')->__('%s RSS Feed',$this->getCurrentCategory()->getName());
                $headBlock->addItem('rss', $this->getRssLink(), 'title="'.$title.'"');
