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!

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.

Product Subdomain Outranking "Marketing" Domains

Hello, Moz community! I have been puzzling about what to do for a client. Here is the challenge. The client's "product"/welcome page lives at www.client.com this page allows the visitor to select the country/informational site they want OR to login to their subdomain/install of the product. Google is choosing this www.client.com url as the main result for client brand searches. In a perfect world, for searchers in the US, we would get served the client's US version of the information/marketing site which lives at https://client.com/us, and so on for other country level content (also living in a directory for that country) It's a brand new client, we've done geo-targeting within the search console, and I'm kind of scared to rock the boat by de-indexing this www.client.com welcome screen. Any thoughts, ideas, potential solutions are so appreciated. THANKS! Thank you!

Bloking pages in roborts.txt that are under a redirected subdomain

Hi Everyone, I have a lot of Marketo landing pages that I don't want to show in SERP. Adding the noindex meta tag for each page will be too much, I have thousands of pages. Blocking it in roborts.txt could have been an option, BUT, the subdomain homepage is redirected to my main domain (with a 302) so I may confuse search engines ( should they follow the redirect or should they block) marketo.mydomain.com is redirected to www.mydomain.com disallow: / (I think this will be confusing with the redirect) I don't have folders, all pages are under the subdomain, so I can't block folders in Robots.txt also Would anyone had this scenario or any suggestions? I appreciate your thoughts here. Thank you Rachel

Page Speed or Size?

Hi everyone. I have a client who really wants to add a 1min html5 video to the background of their homepage. I have managed to reduce the size of the video to 20MB and I have tested the page in pingdom. The results are 1.85 s to load, and weighed in at 21.2 MB. My question is does Google factor page load speed or size in it's ranking factors? I am also mindful of the negative effect this could have on bounce rate. Thanks.

Removing images from site and Image Sitemap SEO advice

Hello again, I have received an update request where they want me to remove images from this site (as of now its a bunch of thumbnails) current page design: http://1stimpressions.com/portfolio/car-wraps/ and turn it into a new design which utilized a slider (such as this): http://1stimpressions.com/portfolio/ They don't want the thumbnails on the page anymore. My question is since my site has a image sitemap that has been indexed will removing all the images hurt my SEO greatly? What would the recommended steps to take to reduce any SEO damage be, if so? Thank you again for your help, always great and very helpful feedback! 🙂 cheers!

Deleting Subdomain - 301 to Homepage Best Option?

We have a subdomain with lots of content that we think Google may consider thin, so we're thinking of removing it to improve our SEO. Is the best way to do this to simply remove the directory and then 301 everything to our homepage? Basically the subdomain consists of product images with links to retailers where they can be purchased. We've basically used it to refer our Facebook fans to when they like a product they've seen on our Facebook page, so the subdomain was not meant to rank for SEO purposes. However, it is integrated with our main webpage, and it is possible that it is hurting our SEO efforts. The subdomain is photos.yournextshoes.com and the main domain www.yournextshoes.com

Rankings of Subdomains vs. Main Domain

Here's a puzzler... Our main domain (www.ides.com) doesn't appear in Google (but does on Bing and other engines). We think this is due to duplicate content which we're fixing. However our website's subdomains continue to appear prominently in SERPs, even on Google - here are some examples: IDES Prospector = prospector.ides.com IDES = support.ides.com Cycolac FR15 = catalog.ides.com Why would Google penalize a main domain and its subdomains?

WordPress Pretty Permalinks vs Site Speed

A couple of issues at play here as I wrestle with the best permalink structure for a site I'm toying with now. 1. I know that WordPress wants a unique number in the post to improve performance and db calls. 2. I know that for basic on-page SEO, most of us would opt for CATEGORY/POST or maybe even just post. I constantly change those. It's a bad habit, but sometimes you want the killer headline and a decent title in the post. So here is the issue: I can rewrite or use a plugin (anyone have a favorite) the permalinks to speed up site performance. We all know Google wants that. Maybe the permalink becomes /1234-foo But you know, a number in front of the URL just isn't awfully user friendly. If someone wants to read the foo post, it's nice to send them directly there. So would you trade off a slowdown in site speed for the prettiest permalinks for usability and SEO? And since you're asking a WP question, has anyone heard of a hard cap on static pages where the database starts dragging? The site I have in mind has 400 each posts and pages. Would moving platforms to Drupal or Joomla allow handling that many pages more effectively? Thanks for contributing and any help you can give. George

Starting a new product, should we use new domain or subdomain

I'm working with a company that has a high page rank on it's main domain and is looking to launch a new business / product offering. They are evaluating either creating a subdomain or launching a brand new domain. In either case, their current site will link contextually to the new site. Is there one method that would be better for SEO than the other? The new business / product is related to the main offering, but may appeal to different / new customers. The new business / product does need it's own homepage and will have a different conversion funnel than the existing business.
