zencart对标题,关键字,描述更新和值的判断

[Table Grove]

标题,关键字,描述对于GOOGLE 和BAIDU等搜索引擎来说是非常重要的.当然对SEO工作人员来说也很看重. 在zencart电子商务网站中的一些修改和对某一个列表页面的某些控制,在zencart程序文件中体现出来.这里就说对zencart对标题,关键字,描述的更新和值的判断.

前面已经说过了对Zencart的一些静态化的设置,这里就不讲了,直接进入文件”include/ includesmodulesmeta_tags.php在这里写着的是所有URL的生成.

以下是对产品页的一些的标题,关键字,描述的一些生成.

// unless otherwise required product_reviews uses the same settings as product_reviews_info and other _info pages

case ‘product_reviews’:

// unless otherwise required product_reviews_info uses the same settings as reviews and other _info pages

case ‘product_reviews_info’:

$review_on = META_TAGS_REVIEW;

// case ‘product_info’:

case (strstr($_GET[‘main_page’], ‘product_’) or strstr($_GET[‘main_page’], ‘document_’)):

你可以对里面的TITLE, KEYWORDS, DESCRIPTION进行修改,以达到自己的目的,不过建议一点程序也不懂的就不要乱改.
