Most social and SEO plugins can use a post’s featured image, or offer a way to select a custom social image, but do little else to make sure an image is suitable for social sharing – they assume the article author / editor is aware of each social site’s image requirements (minimum and maximum image resolution, aspect ratio, and maximum image file size) and has selected an appropriate image. For example, Facebook requires that all images be larger than 200x200px, preferably 600x315px, or (even better) 1200x630px for high-resolution displays like retina laptops and phones, have an aspect ratio no wider / taller than 3:1, and less than 8 MB in size. Twitter and Google also have their own requirements, which are different than Facebook’s.
Using a social or SEO plugin that creates resized images from the originals you upload, and checks those resized images to make sure they conform to the requirements of each social site, is only part of a complete Quality Assurance solution. All too often, themes also include a few basic social meta tags in their templates (they shouldn’t, but they often do), that prevent social crawlers from reading your webpage meta tags correctly – some meta tags should never be duplicated (Facebook, for example, can reject all meta tags because of a single duplicate), or the theme may include the full size featured image before all other meta tags, so the wrong image will be used for social shares (this is fairly common). If your social or SEO plugin does not check for duplicate meta tags, you may never realize that you have a problem.
The WPSSO Core plugin and its WPSSO Schema JSON-LD Markup add-on do an outstanding job of analyzing your content and pulling out information about images, videos, authors, publishers, locations, events, recipes, e-commerce products, SEO customizations, and much, much more — not just from WordPress, but from many 3rd party plugins and services as well. ;-)
The following modules are included with the Pro version of WPSSO Core, and are automatically loaded if/when the supported plugins and/or services are required.
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.
In this post we’ll focus on the Organization markup — using Google’s preferred LD+JSON structured data format — which Yoast SEO, WPSSO Core, and most SEO plugins add to a WordPress site’s homepage.
Google uses the Organization markup to enrich its Knowledge Graph information for the website’s Organization (aka Business, Corporation, etc.).
See Google My Business, Your business information in the knowledge panel, and Improve your local ranking on Google for more information on Google’s Knowledge Graph and local business markup.
See Google’s About Search Features and Structured Data General Guidelines for more information about the current Schema types recognized by Google.
WPSSO Core (and its 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 add-ons.
A new add-on for WPSSO Core called WPSSO Tune WP Image Editors is the fastest and easiest way to improve your social and SEO images — simply activate and regenerate your thumbnail images (aka resized images), and you’re done! :-)
How does it work?
Have you noticed that after carefully adjusting an image in Photoshop, you upload it to your site and WordPress creates small images that seems a bit “fuzzy” — nothing like the nice sharp original?
The reason is that after resizing any image, that image must be sharpened – always, but WordPress doesn’t do any sharpening, so the resized image remains a bit “fuzzy” — probably not what you want for a featured image or share on social sites! ;-)
The WPSSO Tune WP Image Editors add-on takes care of this — it automatically applies a reasonable amount of sharpening to all JPEG images resized using the default WordPress ImageMagick editor.
WPSSO Breadcrumbs Markup (aka WPSSO BC) version 1.0.0 for WPSSO Core was released yesterday. You can install and activate the extension from the SSO > Extension Plugins settings page, download it from the WPSSO website, wordpress.org, or GitHub.
Uses Google’s preferred Schema JSON-LD format.
Most comprehensive Schema BreadcrumbsList markup of any plugin.
Adds Schema BreadcrumbList markup to posts, pages, and custom post types.
Select between using ancestors (page parents, grand-parents, etc.) or categories for breadcrumbs.
No theme function or template files to modify!
Simply activate / deactivate the plugin to enable / disable the addition of Schema BreadcrumbList markup.
