+# Google SEO Notes for eCommerce
+
+These are loose notes about what I am learning about boosting SEO for an e-commerce site. 
+
+- [Google Search Central](https://developers.google.com/search) is where you can go to find info about how to help your site do better in Google rankings.
+- You can add [structured data](https://developers.google.com/search/docs/appearance/structured-data/intro-structured-data) to your html templates to help Google learn more about your site.
+- You can find the schemas for the structured data at [Schema.org](https://schema.org).
+- JSON-LD is [JSON for Linking Data](https://json-ld.org) and is one form of structured data. It is also the one I will be using.
+- You add "snippets" in specific formats that are specifed in the schemas, and this helps Google render your information in more helpful ways, and helps people find your site 
+
+## `offers` 
+
+- [The `Product` Snippet](https://developers.google.com/search/docs/appearance/structured-data/product-snippet)
+- [`Offer` on Schema.org](https://schema.org/Offer)
+
+Adding data from the [`Product` snippet](https://developers.google.com/search/docs/appearance/structured-data/product-snippet) to your [structured data](https://schema.org) (in my case, [JSON for Linking Data](https://json-ld.org)) helps Google show that you have products for sale.  
+
+In practice, this feels similar to setting up a `meta` tag
+
+### Adding `ld+json` with pricing information to a Django template 
+
+```html
+<!-- /templates/product_list.html
+
+{% block extra_head %}
+    <script type="application/ld+json">
+    {
+      "@context": "https://schema.org/",
+      "@type": "ItemList",
+      "name": "Products for Sale",
+      "itemListElement": [
+        {% for product in products %}
+        {
+          "@type": "ListItem",
+          "position": {{ forloop.counter }},
+          "item": {
+            "@type": "Product",
+            "name": "{{ product.name }},
+            "url": "{{ request.scheme }}://{{ request.get_host }}{{ product.get_absolute_url }}",
+            "offers": {
+                "@type": "Offer",
+                "price": "{{ product.default_price }}",
+                "priceCurrency": "USD"
+              }
+          }
+        }{% if not forloop.last %},{% endif %}
+        {% endfor %}
+      ]
+    }
+    </script>
+{% endblock extra_head %}
+
+```
+
+This snippet does the following: 
+
+- Add a `<script>` tag for the `ld+json` structured data about our products for sale to our product-list template
+- Declares our schema in `@type`
+- Loops through our products to set up each `item` attribute
+- Creates an `offers` attribute for each product, where we can add pricing information
+
+<hr> 
+
+There are a lot of other options for adding product information to templates to improve their search performance. I'm going to look through the specification and do a little reading on how important the different attributes are.
