Is Base64 encoding images in general better for SEO or worse?
-
We've made a lot of changes to our website (https://refreshcartridges.co.uk/) over the years, with our website developer putting a heavy emphasis on improving page loading times in general.
One of the those changes has been to base64 encode or in-line the majority of images on our site which has reduced our loading times down to under a second for most of our pages for our visitors which are mainly based in the UK.
My question is whether in-lining the images, thus removing the images filenames for index association results in this technique being a net-good or net-bad for our sites SEO in general, particularly on our frontpage.

Hi Chris,
To my understanding, my take is that, unless Google Image search is an important channel for your business, the improvements to page speed/UX will be a net gain for SEO.
Using Base64 encoding for images may result in those images falling out of Google Image search, but the pages themselves are not likely be negatively impacted.
Caveat: Google has not communicated on the impact of this specifically, and we've not tested this with Distilled clients - I've based my answer on my understanding of Google's technology, their emphasis on all things page speed and the fact that this approach is growing across the web (so it's likely Google has already solved for this or else will have soon).
Best,
Mike

Size of image for article Schema
Hi, I implemented schema markup for an article and all tested fine and I can see it being fired in preview mode of Google Tag Manager. But when I run the URL which has it applied through Google Structured Testing tool it is not appearing. I have now read that the image needs to be a certain size. For AMP articles this appears to be 12oo pixels wide http://www.thesempost.com/google-changes-image-size-requirements-amp-articles/ But what about non-AMP articles? Does it need to be that big too?

Google not Indexing images on CDN.
My URL is: https://bit.ly/2hWAApQ We have set up a CDN on our own domain: https://bit.ly/2KspW3C We have a main xml sitemap: https://bit.ly/2rd2jEb and https://bit.ly/2JMu7GB is one the sub sitemaps with images listed within. The image sitemap uses the CDN URLs. We verified the CDN subdomain in GWT. The robots.txt does not restrict any of the photos: https://bit.ly/2FAWJjk. Yet, GWT still reports none of our images on the CDN are indexed. I ve followed all the steps and still none of the images are being indexed. My problem seems similar to this ticket https://bit.ly/2FzUnBl but however different because we don't have a separate image sitemap but instead have listed image urls within the sitemaps itself. Can anyone help please? I will promptly respond to any queries. Thanks

Is Removing Breadcrumbs Detrimental for SEO?
We have full navigational breadcrumbs on our site for the menu and the brand menu. i.e. Home > Clothing > Jackets Brand > Brand Name > Brand Jackets There's been talk of removing this and having it like Chico's does, where on item pages they just have a link at the top to previous category (i.e. you're on a shirt product page and at the top it says "Back to Tops" instead of listing Home > Clothing > Tops) Is doing something like this detrimental to SEO? From what I've read Breadcrumbs are for user experience but I just want to be sure.

Removing images from site and Image Sitemap SEO advice
Hello again, I have received an update request where they want me to remove images from this site (as of now its a bunch of thumbnails) current page design: http://1stimpressions.com/portfolio/car-wraps/ and turn it into a new design which utilized a slider (such as this): http://1stimpressions.com/portfolio/ They don't want the thumbnails on the page anymore. My question is since my site has a image sitemap that has been indexed will removing all the images hurt my SEO greatly? What would the recommended steps to take to reduce any SEO damage be, if so? Thank you again for your help, always great and very helpful feedback! 🙂 cheers!

Do Abbreviations Hurt SEO Results?
We have certain products that we've abbreviated since it's a bit too long. For example, the word Fair Trade Organic is one of our categories and we abbreviate it to FTO. If I put FTO on our meta tag titles and links instead of the actual word, would that provide a weaker result?

Do the search engines penalise you for images being WATERMARKED?
Our site contains a library of thousands of images which we are thinking of watermarking. Does anyone know if Google penalise sites for this or is it best practice in order to protect revenues? As watermarking these images makes them less shareable (but protects revenues) i was thinking Google might then penalise us - which might affect traffic Any ideas?
