[Solution] Sharper Thumbnails for Facebook, Google, Open Graph, Pinterest, Schema, SEO, Twitter, etc.

Pop quiz! Did you know?

1) WordPress creates thumbnails automatically?

WordPress uses the larger / full-size image you upload to create smaller thumbnail images (see your WordPress Settings > Media page for the complete list of sizes).

For example, a photo gallery page will show small thumbnails of the larger / full-size images you uploaded. Themes will often include the featured image you selected in a predefined image size and location in the webpage.

2) All images must be sharpened after resizing?

This is such a standard process that Photoshop, for example, automatically applies a default amount of sharpening when resizing any image — you must specifically uncheck an option in Photoshop to avoid sharpenning an image during the resize process!

3) WordPress does not sharpen resized images?

[Solution] Google Reports Missing “Product Identifier” for WooCommerce Products

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.

Why WordPress Image Sizes for Social Sharing and SEO?

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. og:image, twitter:image, etc.), and/or adding images to Schema JSON-LD markup for the webpage. This can be problematic for several reasons…

  1. The image resolution may be too small.
  2. The image resolution may be too large and the file size too big.
  3. The aspect ratio (width or height) may exceed a maximum value.
  4. The image displayed on the social / search site is center cropped.

The Fastest Way to Improve Social and SEO Images

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.
