WooCommerce manages information on product Availability (aka Stock), Prices, SKU, etc., but additional WooCommerce product attributes must be created to provide more product information for Google.
The WPSSO Core Pro plugin (and its WPSSO Schema JSON-LD Markup Pro add-on), for example, include a variety of WooCommerce product attribute values in its Schema markup, including the product Brand, Color, Condition, EAN, GTIN-8, GTIN-12, GTIN-13, GTIN-14, ISBN, Material, MPN (aka Manufacturer Part Number), Size, and Gender.
All social and SEO plugins – except one that I know of – use the full size image URL from the WordPress media library when adding image meta tags to the webpage (ie.
twitter:image, etc.), and/or adding images to Schema JSON-LD markup for the webpage. This can be problematic for several reasons…
- The image resolution may be too small.
- The image resolution may be too large and the file size too big.
- The aspect ratio (width or height) may exceed a maximum value.
- The image displayed on the social / search site is center cropped.
WPSSO Core Pro and the WPSSO JSON Pro add-on provide complete Schema markup (aka Google’s Product Rich Card) for WooCommerce products, including all variations and extensive product information (size, weight, sale prices / dates, color, condition, etc.) – far beyond the basic Schema markup provided by the WooCommerce plugin itself.
WPSSO Core Pro can also read several custom WooCommerce product attributes, if / when you create them in your WooCommerce store:
There are several ways to add aggregate ratings — as I’ll explain below — but first, before we dive into the “How”, let’s talk about what an “aggregate rating” actually is. ;-) The Schema.org website defines the Schema aggregateRating property value as:
The overall rating, based on a collection of reviews or ratings, of the item.
Two things to keep in mind about this:
- An aggregate rating value is calculated from several customer ratings / reviews for the current webpage content (an e-commerce product review, for example).
- Google prefers — and often double-checks — that Schema markup reflects the current content of the webpage. So, if you want to manually set aggregate rating and/or review values in your Schema markup, make sure that these customer ratings and/or reviews also appear in your webpage content (ie. the ratings and reviews are visible).
Google reads a variety of structured data from webpages, including e-commerce Product details, Recipes, Reviews, etc. — along with three standard Schema types from a website’s homepage: WebSite, Organization, and Person.
Google uses the Organization markup to enrich its Knowledge Graph information for the website’s Organization (aka Business, Corporation, etc.).
WPSSO Core (and its complementary add-ons) can be used by themselves, or in combination with Yoast SEO and other popular SEO plugins — WPSSO Core will warn of any conflicting plugin settings and the Pro version of WPSSO Core includes integration modules to read post / term meta from all the popular SEO plugins. The following examples were created using the Free versions of Yoast SEO, WPSSO Core, and its Free complementary add-ons.
On April 26th – just two weeks ago – WPSSO Core v4.0.0 was released, which included support for the new Gutenberg editor. Since then, WPSSO Core v4.1.0, v4.2.0, and v4.3.0 were also released (the last one just today), along with WPSSO JSON v1.25.0 and v1.26.0.
In case you missed all the update notices and posts about those versions, the following is a quick summary of the big changes and improvements in both WPSSO Core and its JSON-LD add-on. And at the end of this post, you can also find a summary of our release schedule philosophy, and why we chose to release four big improvements, in four different versions, in just two weeks. ;-)
The release of WordPress 5 and the new Gutenberg editor are just around the corner, and Gutenberg developers still have not tackled a serious design issue with the current Gutenberg notification system — notices in Gutenberg are being displayed over the content area, forcing users to dismiss notifications to gain access to their content — and in some cases, where several non-dismissible notices are displayed, users may not have access to the content area at all.
The notification system in the current version of WordPress is nothing fancy — and can feel a bit intrusive when several notices are displayed at once — but it’s a lot more flexible and functional than the proposed Gutenberg notification system. :-) As an example, here are some typical SSO (Social and Search Optimization) notifications when editing a test post in the current version of WordPress, in the Gutenberg editor, and with the upcoming release of WPSSO Core v4.2.0 that moves SSO notices into the admin toolbar.
The new Gutenberg editor for WordPress v5 may not be ready yet — and I can certainly attest to that, lol — but it’s coming soon, and WPSSO Core is ready for Gutenberg!
This latest version of WPSSO Core (scheduled for release this week) includes several key changes aimed specifically at integrating WPSSO Core with the new Gutenberg editor. The Document SSO (Social and Search Optimization) metabox is now refreshed when the Gutenberg post is saved, and any SSO notices are displayed using the new Gutenberg notification system. The notices themselves have also been improved by including more information about the dismiss button — either simply hiding the notice (Gutenberg default), temporarily dismissing it for 1 hour, 3 months, etc, or dismissing it permanently.
Have you tried the Gutenberg editor yet?
WordPress v5 is coming soon, and if you haven’t tried the new Gutenberg editor in a staging environment (contact your hosting provider for details), then you could be in for a major surprise! Many plugins will not be compatible with Gutenberg, and for those few and rare plugin authors that are still actively maintaining their plugins, updates to support the Gutenberg editor may take some time. Save yourself the headache – install the Gutenberg editor in a staging environment now, and make sure all your plugins are compatible. ;-)
WPSSO Core v4.0.0 beta is available now.
If you’re a WPSSO Core Pro user — and have a staging environment — you can select the “Beta and Up” version filter for WPSSO Core in the SSO > Update Manager settings page, to install and test the latest beta version. You can also re-select the “Stable / Production” version filter at any time to re-install the last stable / production version.
There’s an exciting new cache feature coming in WPSSO Core v3.56.0 — a new “Auto-Refresh Cache After Clear All” option will be available under the SSO > Advanced Settings > Cache Settings tab (Pro version).
One of the interesting things about WPSSO is that most cached objects, like meta tags and Schema JSON-LD markup, are created and stored as arrays, independent of the webpage. This makes it possible to loop through all post, term, and user IDs, and re-create those arrays easily — again, completely independently of the webpage (or WordPress action hooks), so no HTTP connection is required — which makes for a very fast and efficient way of creating (or re-creating) cache objects! ;-)
The new “Auto-Refresh Cache After Clear All” option is enabled by default. When you click the “Clear All Cache” button (from any settings page), the WPSSO cache will be cleared and a background task will be started to re-create all the missing WPSSO cache objects. The same class method is also called when the plugin is activated, to optimize the speed of all front-end webpages and back-end editing pages. :)
