伴随着越来越多的外贸B2C电商企业开始投放Google PLA广告，Google Shopping Feed 的数据创建一直困扰着一些外贸电商企业；创建数据 Feed 时，一定要选择最适合商家需要的格式。Google 支持两种常规格式的数据 Feed：文本 (.txt) 和 XML (.xml)。
对于大多数外贸商家，建议你使用 .txt 格式，因为这种格式对技术知识的要求最低。您可以使用电子表格编辑器（例如 Microsoft Excel 或 Google 电子表格）轻松地创建 .txt 数据 Feed。但是这种方法的缺点就是要手动更新数据，比较麻烦。我今天给大家介绍的是用 XML 创建 Feed 数据，产品Feed数据自动更新，管理轻松。在创建 Google Shopping Feed 数据之前，应该先熟读目标国家的商品 Feed 规范和XML格式RSS2.0规范。尽量完善商品 Feed 规范要求的必须和推荐属性，有利于提高 Feed数据的质量和PLA广告的质量。
你需要在IT的帮助下把网站的所有产品生成符合 Google Feed 要求的 RSS 2.0 文档，如下图：
<?xml version=”1.0″?>
<rss version=”2.0″
xmlns:g=”http://base.google.com/ns/1.0″>
<channel>
<title>数据文件的名称</title>
<link>http://www.example.com</link>
<description>内容简介</description>
<item>
<g:id>{sku}</g:id>
<g:item_group_id>{parent_sku}</g:item_group_id>
<title>{name,[substr],[70],[...]}</title>
<link>{url parent}</link>
<g:price>{normal_price}</g:price>
<g:sale_price>{special_price}</g:sale_price>
<g:online_only>y</g:online_only>
<description>{description parent,[html_entity_decode],[strip_tags]}</description>
<g:condition>new</g:condition>
<g:google_product_category>{google_product_categoryparent}</g:google_product_category>
<g:product_type>{product_type parent}</g:product_type>
<g:image_link>image_link parent</g:image_link>
<g:availability>{is_in_stock parent?[in stock]:[out ofstock]}</g:availability>
<g:quantity>{qty}</g:quantity>
<g:featured_product>{is_special_price?[yes]:[no]}</g:featured_product>
<g:color>{color,[implode],[,]}</g:color>
<g:shipping_weight>{weight,[float],[2]}kilograms</g:shipping_weight>
<g:manufacturer>{manufacturer}</g:manufacturer>
<g:brand>Your Brand</g:brand>
<g:upc>{upc}</g:upc>
<g:adwords_labels>{product_category}</g:adwords_labels>
</item>
</channel>
</rss>
特别备注：
1.{}里的变量对应你网站上各个属性的变量；
2.红色属性代表 Google Feed 规范的要求的必要属性，这里主要参考 Summary of Attribute Requirements；
3.对于面向美国、英国、德国、法国和日本的 Feed：属于 ‘服饰与配饰‘ 类别（包括所有子类别）的所有商品都必须提供本部分中的以下属性：性别（gender）、年龄段(age)、颜色（color）、尺寸(size)。
然后，叫IT把生成的 Google Shopping Feed URL 给你，比如 http://www.example.com/googleshopping-us.xml，Feed URL打开如下图所示（下图中我只列举了一些 Feed 的必须属性）：
登录你的 Google Merchant Center，点击”Data feeds > New Data Feed“,如图：
Format 选择 “googlebase“，新建一个Data feed filename命名为”googleshopping-us“，如图：
点击”Create schedule“，如图：
下图，然后弹出一个窗口，Upload 你可以选择按月、周、日三种不同的时间更新数据，我推荐选择”Daily“即日更新数据，这样能保证数据的及时性和有效性；Timezone(时区)可以更具需要选择，我推荐选择目标国家的时区；Feed URL 区域填写Google Shopping Feed的路径”http://www.example.com/googleshopping-us.xml“，一定要填写正确，否者无法正确抓取数据；如果你的Feed URL设置有密码保护，请输入用户名和密码即可。如图：
然后点击”Schedule and fetch now“，Google 就会立即抓取所有 Feed URL 下所有的产品数据，几分钟之后，查看是否抓取有误；如果有误，Google 会提示原因，然后按照提示修改即可。
这样如果在网站上修改产品数据（比如价格，库存等等），Google会自动抓取和更新，Google Merchant Center 的产品数据会自动更新，无需重新整理和上传产品 Feed 数据，很方便。
注意事项：
1.要为其排定计划的文件的大小必须小于 1 千兆字节 (GB)，且不得阻止用户代理“Googlebot”访问包含 Feed 的目录（网站的robot.txt文件）。
2.请确保 Feed 网址采用了某种我们支持的文件格式直接指向您的数据 Feed 文件。 请注意，如果指向您网站上的某个 HTML 网页，将导致系统无法处理您的 Feed。
3.及时关注 Google Feed 标准和 Google 购物政策的变化，以便调整 Feed。
