Solidus SEO

Successful stores keep SEO as a top priority. This Solidus extension adds common-sense defaults for structured data, meta tags, Open Graph protocol, and image optimization.

Please note that we are still striving to improve this extension and we warmly welcome community contribution, engagement, and support.

Let us know what you'd like to see added next; we promise to respond to any issues as soon as possible.

Installation

Add solidus_seo to your Gemfile:
```
gem 'solidus_seo'
```
Bundle your dependencies and run the installation generator):

NOTE: During this step, you will be prompted to decide whether or not you'd like to generate the overrides that are included in solidus_seo. These overrides require 'deface' and are intended to be used with solidus_frontend. If you are not using solidus_frontend, you'll have to figure out where is best to manually insert the solidus_seo helpers into your custom views. Continue reading for more information.
```
bundle

bundle exec rails g solidus_seo:install
```
Make sure you've added your store metadata from the Solidus store administration page, like SEO title, store URL and meta description.
(Optional) Override the stubbed methods and/or default helpers provided by this gem to provide extended functionality. [This is further explained below in the Usage section.]

Usage

Views

As mentioned in the above section, we use Deface to insert some helpers that generate the meta and structured data. This, of course, only works if you're using/overriding the default Solidus views from solidus_frontend.

Otherwise, if you're using custom non-Solidus views, we assume you're smart enough to figure out for yourself where to put these helpers ;)

Here are the changes we make, via deface, in the default Solidus views as part of the minimal installation:

In spree/shared/_head.html.erb:
- Replace the <%== meta_data_tags %> line for <%= display_meta_tags %>.
- Remove the <title> tag (display_meta_tags generates a new title tag).
In spree/layouts/spree_application.html.erb
- Insert <%= render 'solidus_seo/analytics' %> just before </head>.
- Insert <%= render 'solidus_seo/noscript_tags' %> immediately after the <body> opening tag.
- Insert <%= dump_jsonld %> just before the </body> closing tag.
- Replace <%= taxon_breadcrumbs(@taxon) %> with (<%= taxon_breadcrumbs_jsonld(@taxon) %>) which does the same as the original plus prints a JSON-LD tag.
- Replace <%= flash_messages %> with (<%= flash_messages(ignore_types: 'added_to_cart') %>) which does the same as the original plus prints a JSON-LD tag.
In spree/products/show.html.erb:
- Insert <%= jsonld @product %> anywhere inside the cache block.
In spree/shared/_products.html.erb:
- Insert <% jsonld_list(products) %> at the bottom of the file. (Notice this helper doesn't generate any output, as instead it simply adds to the data that's later outputted by dump_jsonld)

At this point, assuming you're using the default Solidus views and this extension's deface overrides, the features you've gained are:

Default meta tags including open graph tags, describing a product on the PDP pages, and describing the store/site in all other pages.
Store JSON-LD markup on all your pages.
Product JSON-LD markup in your PDP pages.
Breadcrumb JSON-LD markup in your taxon pages.
ItemList JSON-LD markup in your paginated product pages.
Site-wide default paperclip image optimization (through image_optim)
Page view and eCommerce conversion tracking (completed checkouts) enabled via presence of GOOGLE_TAG_MANAGER_ID, GOOGLE_ANALYTICS_ID, FACEBOOK_PIXEL_ID, PINTEREST_TAG_ID environment variables (only one Google integration should be enabled at a time).

Models

This gem is intended to provide a progressive implementation approach. To begin with, it defines some methods in your models to be used as an interface/source of your meta data. Moreover, it already provides some useful defaults that can be easily extended and customized, all inside your Spree models, via decorators.

Practically speaking, what this means is that simply by setting your store's metadata from the admin and calling the display_meta_tags helper in your layout, you'll get basic JSON-LD data included for your store. The output would be similar to the following:

{
  "@context": "http://schema.org",
  "@type": "Store",
  "name": "Your Store Name",
  "logo": "https://yourstore.com/store_logo.jpg",
  "image": "https://yourstore.com/store_logo.jpg",
  "url": "https://yourstore.com",
  "@id": "https://yourstore.com",
}

Likewise, with no additional customization, overrides, or decorators, a call to jsonld @product will produce the following example output:

{
  "@context": "http://schema.org/",
  "@type": "Product",
  "name": "Ruby on Rails Tote",
  "url": "http://example.com/products/ruby-on-rails-tote",
  "image": [
    "http://example.com/spree/products/21/large/ror_tote.jpeg?1538529540"
  ],
  "description": "Ruby on Rails Tote",
  "sku": "ROR-00011",
  "offers": {
    "@type": "Offer",
    "priceCurrency": "USD",
    "price": "15.99",
    "itemCondition": "http://schema.org/NewCondition",
    "availability": "http://schema.org/InStock"
  }
}

Beyond this initial behavior, you can override any of these base methods with your own data source. We recommend you take a look at the source to know which properties are available for easy overriding.

The basic requirements for the return values of your methods are straight-forward:

seo_data must return a hash with the same structure expected by set_meta_tags

and
jsonld_data must return a hash, holding a JSON-LD definition.

For the purpose of illustration, a simple example could be adding a new file to your Solidus app, app/models/spree/order_decorator.rb, to implement the jsonld_data interface for Spree::Order; the override for the seo_data interface would be placed and implemented similarly. NOTE: To be clear, this extension provides no default implementation for Spree::Order.jsonld_data - the code below is meant solely as an example override for those new to Solidus and who, accordingly, might be unfamiliar with its override mechanics (decorators).

# app/models/spree/order_decorator.rb

Spree::Order.class_eval do
  include SolidusSeo::Model

  def jsonld_data
    {
      "@context": "http://schema.org/",
      "@type": "Order",
      "seller": Spree::Store.default.jsonld_data,
      "customer": {
        "@type": "Person",
        "name": billing_address.full_name,
        ...
      },
      "orderedItem": [
        {
          "@type": "OrderItem",
          "orderItemNumber": line_items.first.sku,
          "orderQuantity": line_items.first.quantity,
          "orderedItem": line_items.first.product.jsonld_data,
          "orderItemStatus": "http://schema.org/OrderDelivered",
          "orderDelivery": {
            "@type": "ParcelDelivery",
            "expectedArrivalFrom": ...
          }
        }
      ]
    }
  end
end

After adding the new decorator, all that's left would be adding a call to jsonld helper on the object, such as:

<%= jsonld(@order) %>

In short, jsonld parses any object that implements the to_jsonld method (added by SolidusSeo::Model module), which in turn makes use of the jsonld_data method, and returns a script tag.

Besides these base methods, there are some model-specific ones for Spree::Store and Spree::Product which are explained in the following sections. These are intended to provide you with some additional common and useful data.

Spree::Store

Again, even without any additional work beyond the initial installation, you get a solid/basic JSON-LD definition for your Spree::Store model. By default:

{
  "@context": "http://schema.org",
  "@type": "Store",
  "name": "Your Store Name",
  "logo": "https://yourstore.com/store_logo.jpg",
  "image": "https://yourstore.com/store_logo.jpg",
  "url": "https://yourstore.com",
  "@id": "https://yourstore.com",
}

Beyond this, there are properties you'll probably want to add to your store definition, like address and profile.

We provide some data-source methods for these common properties without having to redefine the jsonld_data method. You can therefore easily override any of them from within your Solidus app (inside app/models/spree/store_decorator.rb). For example:

# app/models/spree/store_decorator.rb

Spree::Store.class_eval do
  def address_prop
    {
      "streetAddress": "123 Custom Address St",
      "addressLocality": "Cityville",
      "addressRegion": "New Vermont",
      "postalCode": "05001",
      "addressCountry": "US"
    }
  end
end

The *_prop stubbed methods are listed below:

Address [schema]

def address_prop
  {
    "streetAddress": "1600 Pennsylvania Avenue",
    "addressLocality": "Washington",
    "addressRegion": "District of Columbia",
    "postalCode": "20500",
    "addressCountry": "US"
  }
end

Contact points [schema]

def contact_points_prop
  [
    {
      "telephone": "+11111111111",
      "contactType": "customer service",
    },
    # ...
  ]
end

Opening hours specification [schema]

def opening_hours_specification_prop
  [
    {
      "dayOfWeek": [
        "Monday",
        "Wednesday",
        "Friday"
      ],
      "opens": "12:00",
      "closes": "22:00"
    },
    # ...
  ]
end

Geo Coordinates [schema]

def geo_prop
  {
    "latitude": -37.3,
    "longitude": -12.68
  }
end

Same as (Social profile) [schema]

def same_as_prop
  [
    'https://facebook.com/mystore',
    'https://twitter.com/mystore',
    # ...
  ]
end

Using the sample data above, the final output would look like this :

{
  "@context": "http://schema.org",
  "@type": "Store",
  "name": "Your Store Name",
  "logo": "https://yourstore.com/store_logo.jpg",
  "image": "https://yourstore.com/store_logo.jpg",
  "url": "https://yourstore.com",
  "@id": "https://yourstore.com",
  "contactPoint": [
    {
      "@type": "ContactPoint",
      "contactType": "customer service",
      "telephone": "+11111111111"
    }
  ],
  "address": {
    "@type": "PostalAddress",
    "streetAddress": "1600 Pennsylvania Avenue",
    "addressLocality": "Washington",
    "addressRegion": "District of Columbia",
    "postalCode": "20500",
    "addressCountry": "US"
  },
  "geo": {
    "@type": "GeoCoordinates",
    "latitude": -37.3,
    "longitude": -12.68
  },
  "sameAs": [
    "https://facebook.com/mystore",
    "https://twitter.com/mystore"
  ],
  "openingHoursSpecification": [
    {
      "@type": "OpeningHoursSpecification",
      "dayOfWeek": [
        "Monday",
        "Wednesday",
        "Friday"
      ],
      "opens": "12:00",
      "closes": "22:00"
    }
  ]
}

Finally, there are other methods that centralize common data used in multiple places in both the seo_data and jsonld_data default definitions: seo_image, seo_description and seo_tagline. (seo_tagline is a general phrase that will be shown as part of the page title on the homepage.) Again, these provide sensible default behavior and can be overridden if required.

And if you're wondering where the seo_keywords helper is, well, it doesn't exist - and honestly, you should no longer care about your meta keywords at all.

Spree::Product

Beside the seo_data and jsonld_data methods, there are also some common convenience methods for this particular model, namely:

seo_name
seo_url
seo_images: An array of -at least- one absolute image url. The recommendation is to use 3 images, each with one of the following proportions: 1x1, 19:6, 4:3.
seo_description: By default, it fallbacks to the meta_description field or if empty, to description.
seo_brand: By default, it uses the name of any assigned taxon that belongs to a taxonomy named 'Brand' or 'Brands'.
seo_currency
seo_price

(NOTE: Unlike Spree::Store model, there are no *_prop methods for Spree::Product.)

Image optimization

In order to enable image optimization, just tell paperclip to use :paperclip_optimizer processor as described in Paperclip Optimizer's usage guide. We already provide a paperclip optimizer initializer and configuration file (created at config/image_optim.yml) with sensible defaults for a quick start and to save you some hassle. We recommend that you also optimize your pipeline assets by using config.assets.image_optim = true in production.rb (not recommended for development and test).

Testing

First bundle your dependencies, then run rake. rake will default to building the dummy app if it does not exist, then it will run specs, and Rubocop static code analysis. The dummy app can be regenerated by using rake test_app.

bundle
bundle exec rake

When testing your application's integration with this extension you may use its factories. Simply add this require statement to your spec_helper:

require 'solidus_seo/factories'

spreehood/solidus_seo
