      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

          # Tag - opacity and SEO impact

          Hello,
          I have a query animation 'fade-in-up' on my website: tiffanybarnard.com which moves the H1 tag slightly and fades it in from zero opacity to 1. Will this affect the SEO value of the H1 tag?
          Thank you!

          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.

          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

          CSS background image links bad for seo?

          On one of the websites I manage SEO for, the developers are changing how our graphical links are coded. They're basically coding in such away where there is no anchor text and no alt tag, so for example: So there's no anchor nor alt context for Google's crawler. How badly will this affect SEO, or is it extremely minimal and I shouldn't worry about? Thanks in advance.

          Product Images with organic results in SERP

          Hey Mozzers, I've noticed that several of our product page results in Google have the product image associated with them.  Today is the first day I've seen this.  Does anyone know anything about these?  Has Google put anything out about this?  Here's a couple examples: http://content.screencast.com/users/Will_Swales/folders/Jing/media/08a16dcf-505e-443c-866d-fae6d805743e/2014-03-31_1031.png http://content.screencast.com/users/Will_Swales/folders/Jing/media/04972e7b-f6b2-4e78-ab11-95c52d69a200/2014-03-31_1056.png What's interesting is that they don't show for me when I use Chrome's Incognito mode. Any insights much appreciated! Will

          Cyrillic letter in URL - Encoding

          Hi all We are launching our site in Russia. As far as I can see by searching Google all sites have URLs in latin letters. Is there a special reason for this? - It seems that cyrillic letters also work. My technical staff says that it might give some encoding problems. Can anyone give me some insight into this? Thanks in advance.. / Kenneth

          Changing DNS -- SEO implications?

          Hey Moz, We're migrating an old site on an old server over to a new server/DNS. The plan is to keep the same URL structure and reuse our existing URL's. As long as we make minimal changes to each page's content, we should be able to update our DNS entry and get all the pages recreated and assigned to their correct URLs without any reduction in SEO rankings. Is this correct? This site gets a lot of organic traffic and ranks highly on some challenging keywords, so it's key that we retain our rankings as much as possible. I've read that it's wise to lower the DNS time-to-live to one hour, about a day before the move, to help Google crawl the DNS a little quicker. Are there any other recommendations you guys can offer or past experiences?
