Not using alt tags for decorative images?
-
Hi everyone,
My coworker recently stumbled across this article that instructs you to not to alt text for "decorative images" as you might get penalized you for over optimization

Has anyone heard of this or have any thoughts?

Thank you!

It's more of an accessibility issue than an SEO issue. If your visitor were using a screen reader, would it add any value for them to hear the alt text? If so, keep it. If instead you're describing "curly swash with a heart" and it has no bearing at all on actual content, leave it blank. Generally speaking, things that improve your accessibility are good for SEO.

Alt Text Best Practices
I am working on alt texts for my WordPress website. I've done a bit of research and read best practices, but I am a bit confused on how to write some of the alt texts because my entire site includes images. I know this is a big no-no and I am working with my team to get the site SEO-optimized (better text to image ratio). However, in the meantime, I need to make sure that I have some alt texts for my images. Can someone help with the following questions: 1.) I have the same "close" button in 4 locations. Can I use "close" as the alt text four times? Or should I explain where the close button is or what it closes? 2.) If my image is only text and it is more than 125 characters, is this a problem? Should I use longdesc=? If so, how do I input that in a WP site? 3.) If I have my logo in 3 locations, should I differentiate the alt text? 4.) If I have FB icon, do I just state Facebook and don't say icon? 5.) I have some background images and they don't really provide relevancy to my site other than aesthetics so should I not have alt attribute? If so, do I just place alt="" in the alt text field or does it have to be in the code? 6.) In WordPress, do I remove the description under “title,” and just put a description under “alt-text?” 7.) Can I repeat alt texts? For example, I have 4 buy now buttons, should the alt text be “buy now” all 4 times or be specific to what they are buying, such as “Buy now – Teatopia Dream On supplement drink?” 8.) I have 4 nutrition label images so can I just state what each label refers to or is it expected to have a long description with all the text on the label? 9.) I have images for desktop vs. mobile. Can I have similar copy for both. The mobile page is not set-up to index so do I even need alt text for the mobile images? 10.) Can I have characters, such as dashes and commas, in the alt text? Does initial cap matter? 11.) For decorative images or when an alt-text is not needed, do I just place alt=”” in the alt text field in WordPress?

Moving Images to Subdomain: SEO Impacts
For sever work- load enhancements we are planning to move our images to a sub-domain. so the files would be located at something like images.domain.com Rather than domain.com/images/ We are a large Ecommerce site so we have a lot of images. These will be self hosted so we are not using a CDN. I'm hoping someone has done the same and if there were any steps they had wished they had taken before making the move/ if they noticed any traffic impacts things like that.

Do I need to use a CNAME for wistia video hosting?
I'm using Wisita for video hosting. My strategy is to allow other sites to embed videos to get links - I want the video linking back to my site not wistia or the embeding site. Do I need to use the Wistia CNAME or is a wistia subdomain acceptable?

Metadata stored in images read by search engines?
Does anyone know if metadata stored in images is read by search engines?My company stores images in digital asset management systems and metadata keyword tags are added to the images, so they can easily be found within the system. Since these keywords are stored in the image file, I was wondering if search engines can read them once the image is placed on the website, but I'm not finding any evidence of this in my research.

Is a website with no images really a good idea?
I have a client who doesn't want to use any images at all on her website. It's a local hvac service provider. This thought has never even crossed my mind before. Who wouldn't want pictures? I know image optimization is important, and my mind keeps telling me that images are important for a good site and good user experience, but are they really necessary? I want a second opinion before I advise against not using any images.
