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

Domain Masking SEO Impact
I hope I am explaining this correctly. If I need to provide any clarity please feel free to ask. We currently use a domain mask on an external platform that points back to our site. We are a non-profit and the external site allows users to create peer-to peer fundraisers that benefit our ministry. Currently we get many meta issues related to this site as well as broken links when fundraisers expire etc. We do not have a need to rank for the information from this site. Is there a way to index these pages so that they are not a part of the search engine site crawls as it relates to our site?

Any SEO benefits of adding a Glossary to our website?
Hi all, I manage a website for a software company. Many terms can be quite tricky so it would be nice to add a Glossary page. Other than that, I have 2 questions: 1. What would be the SEO benefits? 2. How would you suggest to implement this glossary so we can get as much SEO benefit as possible (for example how would we link, where would we place the glossary in the terms of the sitemap, etc.). Any advice appreciated! Katarina

Hosting images externally
In these days of CDNs does it matter for SEO whether images (and PDFs etc.) are hosted off-site? Does it make a difference if images hosted on Flickr, photobucket etc. Thanks

JavaScript page loader - SEO impact
Hello all,
Technical SEO | | Lvet
I am working on a site that has a bizarre page load system. All pages get loaded trough the same Javascript snippet, for example: Changing the values in the form changes the page that is loaded. The most incredible thing is that, against my expectations, pages do get indexed by Google.
My question is: "Does loading pages dynamically using JavaScript affect the overall SEO performance?" Why are pages getting indexed? Thank you for shedding light on this.
Cheers

How do you build your pre-sales seo audit
Hello Moz community, I'd like to know if you build "pre-sales seo audit" when selling your services to a prospect. I think the main idea of a pre-sales audit is to show your prospect that you understand his industry (trends & competition) understand the opportunities know the roadblocks on his website If so, i'd be interested in discussing the information you put into your pre-sales audit and how you organise it. If you know ressources i should read as regards to mini seo audit / pre-sales seo audit just paste the link 🙂 Thanks for your answers

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?

What happens when you put an image in an H1 tag?
I am currently updating some H1 tags for my site but the tags are generated automatically by the text that is entered into a field on our content manager software. However because we need an image in this area as well, the entire field including the code for the image is surrounded by an H1 tag. Is this bad for SEO?
