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.

I'm reaching out for some advice on improving my WordPress website's speed. I'm currently using a free theme for this fusion magazine and aiming for a score of 95+ on Google PageSpeed Insights.

What's the best way for users to upload their images to my wordpress site to promote UGC
I have looked at lots of different plugins and wanted a recommendation for an easy way for patients of ours to upload pictures of them out partying and having fun and looking beautiful so future users can see the final results instead of sometimes gory or difficult to understand before and after images. I'd like to give them the opportunity to write captions (like facebook or insta posts and would offer them incentives to do so. I don't want it to be too complicated for them or have too many steps or barriers but I do want it to look nice and slick and modern. Also do you think this would have a positive impact on SEO? I was also thinking of a Q&A app where dentists could get Q&A emails and respond - i've been doing AMA sessions and they've been really successful and I would like to bring it into out site and make it native. Thanks in advance 🙂

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.

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?

Tools/Software that can crawl all image URLs in a site
Excluding Screaming Frog, what other tools/software to use in order to crawl all image URLs in a site? Because in Screaming Frog, they don't crawl image URLs which are not under the site domain. Example of an image URL outside the client site: http://cdn.shopify.com/images/this-is-just-a-sample.png If the client is: http://www.example.com, Screaming Frog only crawls images under it like, http://www.example.com/images/this-is-just-a-sample.png

Do the search engines penalise you for images being WATERMARKED?
Our site contains a library of thousands of images which we are thinking of watermarking. Does anyone know if Google penalise sites for this or is it best practice in order to protect revenues? As watermarking these images makes them less shareable (but protects revenues) i was thinking Google might then penalise us - which might affect traffic Any ideas?

Best geotargeting strategy: Subdomains or subfolders or country specific domain
How have the relatively recent changes in how G perceives subdomains changed the best route to onsite geotargeting i.e. not building out new country specific sites on country specific and hosted domains and instead developing sub-domains or sub-folders and geo-targeting those via webmaster tools ? In other words, given the recent change in G perception, are sub-domains now a better option than a sub-folder or is there not much in it ? Also if client has a .co.uk and they want to geo-target say France, is the sub-domain/sub-folder route still an option or is the .co.uk still too UK specific, and these options would only work using a .com ? In other words can sites on country specific domains (.co.uk , .fr, .de etc etc) use sub-folders or domains to geo-target other countries or do they have no option other than to develop new country specific (domains/hosting/language) websites ? Any thoughts regarding current best practice in this regard much appreciated. I have seen last Febs WBF which covers geotargeting in depth but the way google perceives subdomains has changed since then Many Thanks Dan
