Speed benefits from loading images from a subdomain
-
I have read that loading images from a subdomain of your site instead of the main domain will give you speed benefits on load time. Has anyone actually seen that to be the case? Thanks!

Thanks for the helpful advice!

If you are talking about using a cookie-free subdomain, that can definitely have an impact on site speed:

Just using a subdomain won't have any benefit, and may even slow things down. Using a CDN for images and other components is usually the quickest and easiest solution for most sites.

Does using a reverse proxy to make a subdomain appear as a subdirectory affect SEO?
Using a reverse proxy only makes it appear that a subdomain is really a subfolder. However, links in the end remain the same. Does this have any negative (or positive) impact on SEO? Does it make it difficult from the blog's (subdomain's) sitemap or robots.txt file to be properly read by search engines?

Can you use multiple videos without sacrificing load times?
We're using a lot of videos on our new website (www.4com.co.uk), but our immediate discovery has been that this has a negative impact on load times. We use a third party (Vidyard) to host our videos but we also tried YouTube and didn't see any difference. I was wondering if there's a way of using multiple videos without seeing this load speed issue or whether we just need to go with a different approach. Thanks all, appreciate any guidance! Matt

Removing site subdomains from Google search
Hi everyone, I hope you are having a good week? My website has several subdomains that I had shut down some time back and pages on these subdomains are still appearing in the Google search result pages. I want all the URLs from these subdomains to stop appearing in the Google search result pages and I was hoping to see if anyone can help me with this. The subdomains are no longer under my control as I don't have web hosting for these sites (so these subdomain sites just show a default hosting server page). Because of this, I cannot verify these in search console and submit a url/site removal request to Google. In total, there are about 70 pages from these subdomains showing up in Google at the moment and I'm concerned in case these pages have any negative impacts on my SEO. Thanks for taking the time to read my post.

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.

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?

Does image domain name matter when using a CDN?
Has anyone does studies on using a different CDN domain name for images on a site? Here is an example:
Technical SEO | | findwell
or
http://cdn.mydomain.com/image.jpg>
mydomain.com ranks highly and many images show up in Google/Bing image searches. Is there any actual data that says that using your real domain name for the CDN has benefits versus the default domain name provided by the CDN provider? On the surface, it feels like it would, but I haven't experimented with it.

Do knowledge base plugins on a subdomain have seo benefit?
Hi SEO Moz, We want to use a knowledge base plugin (cheaper & faster than building it ourselves) where we can have Q&As for our website. We want this to help with our SEO by adding in our keyterms that we want to rank for. We've looked into TenderApp & Get Satisfaction which look like good solutions - however, as they're both on a sub-domain do we get any seo benefit from this? When people link to our knowledge base, will this help our website at all - or is the benefit going to go to TenderApp/Get Satisfaction? For instance - Our website URL is http://widget.products.com The KB URL is http://widgetsupport.products.com If the above plugin is not a good solution, is there anything else that is better? Any help will be greatly appreciated!! Thanks.

Where should a knowledge base be hosted for max. SEO benefit?
A client would like to set up a knowledge base to work in conjunction with their website and we are tossing up whether to go with a hosted solution (and therefore set up as a subdomain) or find a solution that we host on the clients domain (which will presumably have more SEO benefit). We are leaning towards the latter (although are mindful that we need to balance the client’s desire for a quality KB solution). Appreciate your feedback.
