      Hi,

      Our site has a very high domain strength.  Although our site ranks well for general search phrases, we rank poorly for image search (even though our site has very high quality images). Our images are hosted on a separate CDN with a different domain.  Although there are a number of benefits to doing this, since they are on a different domain, are we not able to capitalize on our my site's domain strength?  Is there any way to associate our CDN to our main site via Google webmaster tools?  Has anyone researched the search ranking impacts due to storing your images on a CDN, given that your domain strength is very high?

      Curious on people's thoughts?

        Hi NicB1,

        We use Amazon CloudFront here at SEOmoz and it allows us to setup a CNAME for our CDN. So if you look at our images you will see we use a few different ones, such as cdn.seomoz.org, profile1.seomoz.org and profile2.seomoz.org. While I haven't done any studies on this, I can tell you that we have not seen a major change in image traffic in making the CDN switch a few months ago.

        I'd check with your CDN people and see if you can setup a CNAME and place it on a subdomain.

        Casey

          I'll leave it to others who might have done serious testing on this to discuss findings.  I will say this though - if the CDN is not a domain you own, or can readily show through other optimization efforts that you own it, it's at least partly a matter of "how do we know this site owns these images?".  Purely from SEO best practices thinking, when a site hosts their images, there's a much lower threshold of being able to have them recognized for consideration, let alone associated with image names, alt attributes, and page topical focus.

            Should I use a canonical URL for images uploaded to a blog post in Wordpress?

            Hi, I have a wordpress website that has articles/news posts witch contain imagery. I've noticed that in the Media Library, when you upload an image to a blog post it generates a new permalink ...article-name/article-image-01.jpg I have Yoast SEO plugin and have the option to set a canonical URL for this image. Should I point it back to the actual article? Thanks for any helpers with this.

            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.

            Inurl: search shows results without keyword in URL

            Hi there, While doing some research on the indexation status of a client I ran into something unexpected. I have my hypothesis on what might be happing, but would like a second opinion on this. The query 'site:example.org inurl:index.php' returns about 18.000 results. However, when I hover my mouse of these results, no index.php shows up in the URL. So, Google seems to think these (then duplicate content) URLs still exist, but a 301 has changed the actual goal URL? A similar things happens for inurl:page. In fact, all the 'index.php' and 'page' parameters were removed over a year back, so there in fact shouldn't be any of those left in the index by now. The dates next to the search results are 2005, 2008, etc. (i.e. far before 2013). These dates accurately reflect the times these forums topic were created. Long story short: are these ~30.000 'phantom URLs' in the index out of total of ~100.000 indexed pages hurting the search rankings in some way? What do you suggest to get them out? Submitting a 100% coverage sitemap (just a few days back) doesn't seem to have any effect on these phantom results (yet).

            Links under Meta Description when performing a search

            Doing research for clients, I have came across seeing sites displaying hyperlinks underneath their own meta description. keywords that I have googled that result with hyperlinks displaying under meta descriptions: Google'd: iacquire (brand) bmw wheels (Beyern Wheels, position 1) aftermarket bmw wheels (MMR Wheels, position 2) These companys have hyperlinks underneath their descriptions. Anyone have any ideas why this happens or how it happens?

            No Search Results Found - Should this return status code 404?

            A question came up today on how to correctly serve the right status code on pages where no search results are found. I did a couple searches on some major eccomerce and news sites and they were ALL serving status code 200 for No Search Results Found http://www.zappos.com/dsfasdgasdgadsg http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=sdafasdklgjasdklgjsjdjkl http://www.ebay.com/sch/i.html?_trksid=p5197.m570.l1313&_nkw=dfjakljgdkslagklasd&_sacat=0 http://www.cnn.com/search/?query=sdgadgdsagas&x=0&y=0&primaryType=mixed&sortBy=date&intl=false http://www.seomoz.org/pages/search_results?q=sdagasdgasdgasg I thought I read somewhere were it was recommended to serve a status code 404 on these types of pages.  Based on what I found above, all sites were serving a 200, so it appears this may not be the best practice. Any thoughts?

            How should I structure a site with multiple addresses to optimize for local search??

            Here's the setup: We have a website, www.laptopmd.com, and we're ranking quite well in our geographic target area. The site is chock-full of local keywords, has the address properly marked up, html5 and schema.org compliant, near the top of the page, etc. It's all working quite well, but we're looking to expand to two more locations, and we're terrified that adding more addresses and playing with our current set-up will wreak havoc with our local search results, which we quite frankly currently rock. My question is 1)when it comes time to doing sub-pages for the new locations, should we strip the location information from the main site and put up local pages for each location in subfolders? 1a) should we use subdomains instead of subfolders to keep Google from becoming confused? Should we consider simply starting identically branded pages for the individual locations and hope that exact-match location-based urls will make up for the hit for duplicate content and will overcome the difficulty of building a brand from multiple pages? I've tried to look for examples of businesses that have tried to do what we're doing, but all the advice has been about organic search, which i already have the answer to. I haven't been able to really find a good example of a small business with multiple locations AND good rankings for each location. Should this serve as a warning to me?
