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

SEO + Structured Data for Metered Paywall
I have a site that will have 90% of the content behind a metered paywall. So all content is accessible in a metered way. All users who aren't logged in will have access to 3 articles (of any kind) in a 30 day period. If they try to access more in a 30 day period they will hit a paywall. I was reading this article here on how to handle structured data with Google for content behind a paywall: https://www.searchenginejournal.com/paywalls-seo-strategy/311359/However, the content is not ALWAYS behind a paywall, since it is metered. So if a new user comes to the site, they can see the article (regardless of what it is). Is there a different way to handle content that will be SOMETIMES behind a paywall bc of a metered strategy? Theoretically I want 100% of the content indexed and accessible in SERPs, it will just be accessible depending on the user's history (cookies) with the site. I hope that makes sense.

Do long UTM codes hurt SEO?

Craft CMS SEO Resources
I'm just starting out in freelance SEO & I've taken on a client who is using Craft CMS (version 2.0ish) for their site. I am not even close to being competent enough to manually code via Twig, but I had the main developer install the SEOmatic plugin for me. My question from here is - are there any resources or tips I should be aware of starting out? I just started by updating meta title/descriptions via "New Template Meta(s)" but I'm a bit concerned i'm doing the "template path" thing right - I haven't seen any visible changes in browser, and the SERP preview I'm getting is giving me a broken link. But i'm doing a fresh Moz crawl right now to see if the changes took place or not. so 1. Am I on the right track? 2. How long does it typically take for changes to start to show? 3. Is there anything I should be aware of? any follow up questions just let me know, I'll be following this thread!

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.

Do Letters With Accents Affect SEO?
Hi Guys, My company has a franchise of a foreign company that uses an accent/foreign letter in its brand name. We have to refer to this franchise with this symbol on our website to meet their standards. I've done some research on this but its not conclusive, so i was wondering whether anyone here can confirm this for me; Will using the letter with this symbol impair our rankings for this franchise name? Obviously as a UK business people search for this franchise with a regular letter and not the accented one. I would have thought that Google is clever enough to recognise the meaning of the accented letter by now and therefore it wouldn't affect rankings (much). Furthermore, do you think that it would make any difference to use the HTML element to represent the accent rather than copy and pasting the symbol onto our website? I would've thought this would help Google pick it up, but it might not make a difference anyway! Any help is appreciated. Thanks Sam

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?

What are your best tips for SEO on a shopping cart?
So, I am working on a shopping cart platform (X-Cart) and so far don't like it. Also, the web designer is not someone I've worked with before and he is understandably conservative about access--which limits what I can and cannot do from the back end. One of the things I like to do is include text for the search engines. However, based on conversion, etc., I think the product images on a landing page (main brand info with specific products that show up) should show up first to move toward conversion first. I am thinking of adding the text below the product images on the brand pages so the viewer sees the products first while still keeping the content seo. My practice is to use between 300-350 words minimum on a page. Just wondering what best practices you have for a shopping cart. Care to share? Any tips or hints? Thoughts on what I might do that would be most effective? As always, thanks in advance for your sage advice!
