508 compliance vs good SEO re: Image alt tags
-
I'm currently in debate with our 508 compliance team over the use of alt tags on images. For SEO, it is best practice to use alt tags so that readers can tell what the image represents. However, they are arguing that these images should NOT have alt text as it doesn't add anything to the disability screen reader as the image text would be repetitive with the text on the page. I feel they are taking the "decorative" image concept in 508 compliance too far. It's intention is for images for bullets, etc that truly are decorative in nature and add no benefit to the reader. What is the communities thoughts on this? Have you ever run into scenario where 508 is attempting to ruin SEO? Usually the 2 play nicely.

Even if the image is decorative, it is still describing the contents of the image to visually impaired users. Here's more from Google:
https://support.google.com/webmasters/answer/114016?hl=en
From Google:
"The
alt
attribute is used to describe the contents of an image file. It's important for several reasons:It provides Google with useful information about the subject matter of the image. We use this information to help determine the best image to return for a user's query.
Many people-for example, users with visual impairments, or people using screen readers or who have low-bandwidth connections—may not be able to see images on web pages. Descriptive alt text provides these users with important information."
The image's decorative value is for the user to judge, it's about providing the full story and experience to all users not some.

Hi Rose,
Hopefully Donna answered your question already, but I want to jump in with some SEO prioritization advice.
Alt text like this can add to the relevance of the page, but minimally. It can also help your image rank correctly in image search, but that doesn't bring much traffic now that Google pulls images into its results page.
I had similar conversations with our compliance team when I worked for a university, and they had a similar perspective, that alt text should be determined by the flow of the reader rather than for small SEO boosts. The nice thing is, though, when images are important to the flow of the page, and are more likely for the alt text to support the keywords you're trying to target on a page.
In short: if I were you, I'd let this argument go, and just push for alt text on images that tell a story. There's no SEO penalty for not using alt text, and I doubt you're worried about ranking for "father and young son."
Best,
Kristina

I'm with you Rose. The alt tag describes the image. If you want it to include your your keywords, assuming they're some combination of "Child Support Noncustodial Parent Employment Demonstration" (your page title tag content), you could alter it to say "noncustodial parent with his young son". You could do the same with the file name, include "noncustodial-parent-son".
Here are google's guidelines, as conveyed by Matt Cutts, head of Google's Web spam team and defacto SEO spokesperson.

I'll provide an example. http://www.mathematica-mpr.com/our-publications-and-findings/projects/child-support-noncustodial-parent-employment-demonstration
On the page linked above, there is a medium size image depicting a father and son. The alt text there is "father with young son", the compliance team is arguing that the alt text should be removed as it adds no value. My thought was around changing the alt text to be more specific to the article, but even how it currently is it tells the screen reader that the image is of a father with his young son which is accurate. The compliance team feels these are decorative images - and I can't disagree more. I was hoping to find some evidence to support my case.

I must be thick because I certainly don't understand the statement "they are arguing that these images should NOT have alt text as it doesn't add anything to the disability screen reader as the image text would be repetitive with the text on the page. "
No, I haven't run into this problem before. Perhaps they're referring to situations where alt tags just get stuffed with keywords. Image alt tags shouldn't just repeat the text on the page or act as a repository for keywords, although that's often what you see. Image alt tags should accurately describe the image first, use keywords second and where it makes sense.
So, for example, this page has an alt tag coded for the little blue button above that depicts Roger, the company mascot (<img <span class="html-tag">alt</img <span>="Roger_blue_square"). The text "Roger blue square" doesn't appear anywhere else on the page. (Well I guess it does now!) It's a bit succinct - first time visitors might have a heard time understanding what the image represents - but it is accurate and isn't just stuffed with "Moz Q&A Community" keywords.
I'm waiting for the day when Google decides to start penalizing folks for doing what you've described above.

H Tags in Menu
Hi I am checking the H2 tags on this page https://www.key.co.uk/en/key/dollies-load-movers-door-skates I have noticed my dev team have implemented H2's on the categories in the menu. Will this completely confuse Google as to what that page is about? In my opinion those links shouldn't be heading tags at all

Onsite SEO vs Offsite SEO
Hey I know the importance of both onsite & offsite, primarily with regard to outreach/content/social. One thing I am trying to determine at the moment, is how much do I invest in offsite. My current focus is to improve our onpage content on product pages, which is taking some time as we have a small team. But I also know our backlinks need to improve. I'm just struggling on where to spend my time. Finish the onsite stuff by section first, or try to do a bit of both onsite/offsite at the same time?

How does the use of Dynamic meta tags effect SEO?
I'm evaluating a new client site which was built buy another design firm. My question is they are dynamically creating meta tags and I'm concerned that it is hurting their SEO. When I view the page source this is what I see. <meta name="<a class="attribute-value">keywords</a>" id="<a class="attribute-value">keywordsGoHere</a>" content="" /> <meta name="<a class="attribute-value">description</a>" id="<a class="attribute-value">descriptionGoesHere</a>" content="" /> <title id="<a class="attribute-value">titleGoesHere</a>">title> To me it looks like the tags are not being added to the page, however the title is showing when you view it in a browser and if use a spider view tool, it sees the title. I'm guess it is being called from a DB. So I'm a little concerned though that the search engines are not really seeing the title and description. I'm not worried about the keywords tag. Can anyone shed some light on how this might work? Why it might not being showing the text for the description in the page code and if that will hurt SEO? Thanks for the help!

Image Maps
Hey forum, I'm curious about Image Maps. Few things I'm not sure about: 1. Will the links be followed? If so, will Google respect rel="nofollow"? 2. Will the image be considered 1 image? (indexed as image, etc.) Or will each map segment be treated as a separate image? 3. Any other SEO pros\cons to consider when adding an image map to an existing page? Thanks, Corwin.

tags inside <a>tags - is this bad?</a>
Hi, I'm currently redesigning my website, and in many places, I've now decided to make links a little bit more obvious for the user, using tags within a <a>tag in order to make the entire block of text clickable. I was just wondering if this could have a negative impact in the search engines. My gut feeling is no, since I'm actually improving usability, but I guess it could have an impact on how Google looks at the anchor text? An example of the HTML is as follows: </a> <a></a> <a></a> [Cristal Night Club Hotels <address>1045 5th Street

Migrating online store to subdomain using shopify and effects on seo and energy down the road for seo
I'm looking for some clarity... Looking at using Shopify for an existing online store that we have to migrate. Setting up the store with shopify means we will be using a subdomain such as shop.mywebsite.com instead of mywebsite.com/shop. The following are points to consider when responding The client currently has an online store, however it's a proprietary shopping store and CMS that has since gone defunct and they need to migrate to an alternative in order to survive online against new CMS systems that allow the site and its content to be better optimized. There is a lot of existing SEO done on the current site that we don't want to loose PR on. There is roughly 2000 products Client has a fixed budget, dealing with checkout issues, custom work and various other "bugs" seems to be easier controlled with Shopify...thus budget can be used more on content/strategy and migration We want to run the main site in Wordpress and are wanting to use Shopify since it supports a gateway, has great features and seems like it would allow us to get more bang for the buck and can focus more on the main site and content strategy and drive traffic to the subdomain store if needed Or main concern is the effort of migrating 2000+ products to shopify and the traffic and PR it gives the current site will have a negative effect on the main domain itself. Should we really be considering this path? The domain is diveidc.com One main benefit to the subdomain is the ability to clearly segment products from the service portion of the site in the analytics and focus 2 clear strategies and track it in a very defined manner. We're really on the fence with this...any thoughts are welcome.
