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?
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.
This article was written back in October of 2014 and no longer represents the currently available Yoast SEO and WPSSO Core plugin features — which have both evolved significantly since 2014.
Schema markup in JSON-LD format, which is not discussed here, has become essential for good SEO. The current Yoast SEO plugin offers some basic Schema JSON-LD markup, while the WPSSO Schema JSON-LD Markup add-on for WPSSO Core goes much, much further (and even includes a Premium version for even more Schema options).
The social sharing aspects discussed in this article (meta tags, images, videos, etc.) from Yoast SEO and WPSSO Core are still mostly relevant, although Twitter has since dropped the Gallery, Photo, and Product cards.
A few years ago, most website visitors came from Google Search results. Plugins designed to optimize your content for Google Search became increasingly popular, and part of many “must have” plugin lists. Recently though, that trend has been shifting, as the percentage of visitors coming from social websites is increasing — often matching and sometimes out-pacing — the number of visitors from Google Search. Traditional Search Engine Optimization (SEO) plugins, like WordPress SEO by Yoast for example, have adapted to this change by stepping away from their core purpose, and re-using their SEO content to generate additional meta tags for social websites. But how good is an SEO plugin at addressing the needs of social websites? We compare WordPress SEO to WPSSO, a dedicated social sharing optimization plugin to find out.
