ShortPixel Adaptive Images – WebP, AVIF, CDN, Image Optimization

As the title says, Pagespeed Insights gave a score of 92 on mobile and 99 to 100 on desktop with no visible loss of quality on the web page. What I also like is the very reasonable one time pricing and the fast CDN. Shortpixel also gives 100 free credits a month!

I’ve recently added SPIO across all our WordPress sites. (I work for a NFP managing 10 of their sites.) I’m impressed by ShortPixel’s compression and performance. Adrian and the team have offered great support. And they’ve offered discounts/bonus credits for us as a NFP organisation!

Not here to diss you guys. Your image optimiser plugin is great!! But this one, it didn’t speed up my site, but rather made it super slow on first load. Maybe my error even. BUT when I turned off plugin and checked the inbuilt delete DB tables option, the site was still slow. I had to download WP Optimize and delete the inactive DB tables of the ShortPixel Adaptive Images plugin, then the site was instantly fast again. Probably a rare problem, but if this happens to you, that’s the fix.

After A LOT of research on my side (support was responsive but unfortunately not helpful), I have found that cdn.shortpixel.ai is blocked by Google Search Console. How it affects your SEO may be subject to discussion, but definitively, the facts I’m going to expose are not a good sign. I have read the documentation regarding indexing, and while I understand the theory, the truth is Google disagrees: kb.shortpixel.com/knowledge-base/article/will-my-sites-images-be-indexed-as-coming-from-shortpixel/ Signs that Google disagrees: In Search Console>live test >Screenshot diplays broken images (all of them). “More info” tab on url inspector live shows cdn.shortpixel. ai urls not being loaded. “Other error” Even my favicon is blocked on the results in Google search images. I can’t affirm that my Google Images traffic has dropped because of this plugin, but the truth is that my Google Image traffic has decreased dramatically since I activated it a few months ago. A dramatic amount of images have been deindexed since I installed the CDN. The images that are currently indexed contain a link to the original image on my server (featured images on posts or pages that link to the original image via meta tags, product images, or widgets that, on click, serve the original image from my own server). So my guess is that Google is crawling the urls of the original image. Dramatic traffic drop since I’m using short-pixel CDN. Few posts lately point to the same issue. How did I arrive at the conclusion that Shortpixel AI is the problem? I have tried deactivating all plugins but Shortpixel. Problem persist. I deactivated my theme and activated the WordPress default theme. Problem persist. Deactivating Cloudflare. Problem persist. I deactivated all Hotlink protection. Problem persist. I activated the new AI engine and the problem persist. Only when I deactivate Shortpixel, magic… it works! I use my theme + Cloudflare + Hotlink protection and a bunch of plugins, and the Search Console url inspector loads all the resources; there are no broken images in the screenshot, and the favicon appears on Google Images results. Support apparently has no idea about what is going on, even when there are actually a couple of recent threads pointing to the same problem. So up to date I assume there is NO SOLUTION. MY SOLUTION: I had another website that uses a different plugin developed by another company that also uses Shortpixel server, and it has the ability to serve images via CDN. Just by chance, I decided to switch the license to this website, and I found out that everything works fine in Search Console!!! This plugin uses sp-ao.shortpixel.ai server and it seems Google likes it while Shortpixel AI uses cdn.shortpixel.ai and Google doesn’t, for reasons that I don’t know and that I won’t explore so support can do some work ;)I took the time to write this long post for you, that, like me, has probably been hurt in your SEO (I’m an illustrator, so imagine how much damage it may have caused). I hope those insights point you in the right direction. All the best!Sergio
