      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

        When it comes to hosting images off site, keep in mind that there may be connectivity and image load speed issues associated with these images. I typically wouldn't rely on an image being pulled from someone else's site, even if it was something like Flickr or Photobucket. I don't think those particular services intend for you to use their service like that.

        Rather, we typically will set up a CDN for hosting the images or PDFs, and use a subdomain of the main site in order to host the images. For example, we would set up images.domain.com and pdf.domain.com and put the images and PDFs on the CDN.

          As long as they still have ALT tags and such I don't think it would make any difference.

          The only thing to consider would be the loading speed. As if it has to go off to another server/site to retrieve the image it may take longer to load and affect your page load speed (slow speed is bad for SEO).

            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?

            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.

            Loading images below the fold? Impact on SEO

            I got this from my developers. Does anyone know if this will be a SEO issue? We hope to lazy-load images below the fold where possible, to increase render speed - are you aware of any potential issues with this approach from an SEO point of view?

            Changing images on site without losing ranking

            A number of images on my site rank very well under google image search but need to be replaced with updated versions. If I keep the file name and pixel dimensions identical will switching the image effect my rankings? Thanks!

            Host sitemaps on S3?

            Hey guys, I run a dynamic web service and I will start building static sitemaps for it pretty soon. The fact that my app lives in a multitude of servers doesn't make it easy to distribute frequently updated static files throughout the servers. My idea was to host the files in AWS S3 and point my robots.txt sitemap directive there. I'll use a sitemap index so, every other sitemap will be hosted on S3 as well. I could dynamically mirror the content from the files in S3 through my app, but that would be a little more resource intensive than just serving the static files from a common place. Any ideas? Thanks!

            Do we need to manually submit a sitemap every time, or can we host it on our site as /sitemap and Google will see & crawl it?

            I realized we don't have a sitemap in place, so we're going to get one built. Once we do, I'll submit it manually to Google via Webmaster tools. However, we have a very dynamic site with content constantly being added. Will I need to keep manually re-submitting the sitemap to Google? Or could we have the continually updating sitemap live on our site at /sitemap and the crawlers will just pick it up from there? I noticed this is what SEOmoz does at http://www.seomoz.org/sitemap.

            Crawling image folders / crawl allowance

            We recently removed /img and /imgp from our robots.txt file thus allowing googlebot to crawl our image folders.  Not sure why we had these blocked in the first place, but we opened them up in response to an email from Google Product Search about not being able to crawl images - which can/has hurt our traffic from Google Shopping. My question is:  will allowing Google to crawl our image files eat up our 'crawl allowance'?  We wouldn't want Google to not crawl/index certain pages, and ding our organic traffic, because more of our allotted crawl bandwidth is getting chewed up crawling image files. Outside of the non-detailed crawl stat graphs from Webmaster Tools, what's the best way to check how frequently/ deeply our site is getting crawled? Thanks all!
