      What would you recommend as best practice? Our ecommerce site has a lot of PDFs supporting the product page. Currently they are kept in a sub domain and so are all images.

      Would it be better to keep them all in a subfolder? I've read about blogs being hosted on a subfolder to be better than subdomain but what about pdfs and images?

      thoughts?

        Hi I personally would host them in a subfolder - especially the PDFs as they are likely to gain links and these links will help strengthen your domain.

        However if you have them in a sub-domain they won't have the same benefit from the links as Google essentially treats sub-domains as a separate domain. This will also limit the ranking ability of PDFs as they won't benefit from your domains authority on a sub-domain.

        Have a look at this article for a bit more insight into subfolder vs sub-domain

        - http://www.seomoz.org/blog/understanding-root-domains-subdomains-vs-subfolders-microsites

        I hope this helped..

          When creating a sub-domain, does that sub-domain automatically start with the DA of the main domain?

          We have a website with a high DA and we are considering sub-folder or sub-domain. One of the great benefits of a sub-folder is that we know we get to keep the high DA, is this also the case for sub-domains? Also if you could provide any sources of information that specify this, I can't see to find anything!

          How many images should I use in structured data for a product?

          We have a basic printing website that offers business cards. Each type of business card has a few product images. Should we use structured data for all the images, or just the main image? What is your opinion about this? Thanks in advance.

          How important is the file extension in the URL for images?

          I know that descriptive image file names are important for SEO. But how important is it to include .png, .jpg, .gif (or whatever file extension) in the url path? i.e. https://example.com/images/golden-retriever vs. https://example.com/images/golden-retriever.jpg Furthermore, since you can set the filename in the Content-Disposition response header, is there any need to include the descriptive filename in the URL path? Since I'm pulling most of our images from a database, it'd be much simpler to not care about simulating a filename, and just reference an image id in my templates. Example: 1. Browser requests GET /images/123456
          2. Server responds with image setting both Content-Disposition, and Link (canonical) headers Content-Disposition: inline; filename="golden-retriever"
          Link: <https: 123456="" example.com="" images="">; rel="canonical"</https:>

          Why Google isn't indexing my images?

          Hello, on my fairly new website Worthminer.com I am noticing that Google is not indexing images from my sitemap. Already 560 images submitted and Google indexed only 3 of them. Altough there is more images indexed they are not indexing any new images, and I have no idea why. Posts, categories and other urls are indexing just fine, but images not. I am using Wordpress and for sitemaps Wordpress SEO by yoast. Am I missing something here? Why Google won't index my images? Thanks, I appreciate any help, David xv1GtwK.jpg

          Robots.txt: how to exclude sub-directories correctly?

          Hello here, I am trying to figure out the correct way to tell SEs to crawls this: http://www.mysite.com/directory/ But not this: http://www.mysite.com/directory/sub-directory/ or this: http://www.mysite.com/directory/sub-directory2/sub-directory/... But with the fact I have thousands of sub-directories with almost infinite combinations, I can't put the following definitions in a manageable way: disallow: /directory/sub-directory/ disallow: /directory/sub-directory2/ disallow: /directory/sub-directory/sub-directory/ disallow: /directory/sub-directory2/subdirectory/ etc... I would end up having thousands of definitions to disallow all the possible sub-directory combinations. So, is the following way a correct, better and shorter way to define what I want above: allow: /directory/$ disallow: /directory/* Would the above work? Any thoughts are very welcome! Thank you in advance. Best, Fab.

          What is better for SEO keywords in folder or in filename - also dupe filename question

          Hey folks, I've got a question regarding URL structure. What is best for SEO given that there will be millions of lawyer names and 4 pages per lawyer www.lawyerz.com/office-locations/dr-al-pacino www.lawyerz.com/phone-number/dr-al-pacino www.lawyerz.com/reviews/dr-al-pacino www.lawyerz.com/ratings/dr-al-pacino OR www.lawyerz.com/office-locations-dr-al-pacino www.lawyerz.com/phone-number-dr-al-pacino www.lawyerz.com/reviews-dr-al-pacino www.lawyerz.com/ratings-dr-al-pacino OR www.lawyerz.com/dr-al-pacino/office-locations www.lawyerz.com/dr-al-pacino/phone-number www.lawyerz.com/dr-al-pacino/reviews www.lawyerz.com/dr-al-pacino/ratings Also, concerning duplicate file names: In the first example there are 4 duplicate file names with the lawyers name. (would this cause Google to not index some) In the second example there are all unique file names (would this look spammy to Google or the user) In the third example there are millions of duplicate file names (if 1 million lawyers then 1 million files called "office-locations"  etc (could so many duplicate filenames cause ranking issues) Should the lawyers name (which is the main keyword target) appear in the filename or in the folder - which is better for SEO in your opinion? Thanks for your input!

          Should we stream videos from a subdomain or subfolder?

          This is causing some hand-wrangling and I need some help. Let's say we were developing rich video content for our products and our agency is hosting the content on a new external server. There are already plans to link to these videos from product detail pages, category pages, and landing pages on our main website: www.example.com. Would it be better to create a new subdomain or to use a subfolder with a reverse proxy technique for this video content? It's not truly a microsite and will not have a gallery page to navigate the various videos. For example, would it be better to use this: video.example.com/ ...or this (executed with a reverse proxy😞 www.example.com/video/ Of course, regardless of whether this new content will live on a subdomain or within a subfolder, we plan on creating a video Sitemap using guidance from Justin Hammack in this terrific post.
