Null Alt Image Tags vs Missing Alt Image Tags
-
Hi,
Would it be better for organic search to have a null alt image tag programatically added to thousands of images without alt image tags or just leave them as is.
The option of adding tailored alt image tags to thousands of images is not possible.
Is having sitewide alt image tags really important to organic search overall or what? Right now, probably 10% of the sites images have alt img tags. A huge number of those images are pages that aren
Thanks!

Thanks, guys.
I've adjusted alt images tags on pages that really matter to me for organic. The tens of thousands of other images/pages are just going to have to chillax.

No problem at all. To be honest, it's really not a huge deal and probably not worth the dev budget or manhours required.
In most cases with a site like this, I'd be more inclined to add good alt text for all images on the most popular pages then, as you're working through other pages throughout the life of the campaign, update the alt text while you're at it.
If you're already updating the page title or content on a page, it's not that much extra effort to do the alt text while you're there.

Hi Eric & Chris,
Thanks for the help. Given the size of the site, tens of thousands of pages and more than one image per average page, I guess my real question is how much trouble is this worth? I don't think the image file name is really going to reliably yield alt img text. So, about the most one could do is possibly a site-wide empty tag. Is this really worth it for organic search? Seems like kind of a phony manipulation to appeal to a search algorithm in maybe some microscopic way. But, I could be wrong, so that is why I'm asking here. If it really matters, we'll do it. But if it doesn't, would rather not. Especially when you consider the next thing will be that having empty alt img tags will some day be a small negative, right? That would be so Google of them.

Is it possible to use a script to write? Alternative option is to run a screaming frog crawl looking for all images, download into excel, and use the image file name to help create a tag. That's assuming you've named the image with something specific instead of leaving it default (eg: image4893054893.jpg). Ideally you would want to include image alt tags, and many platforms can help make it easy. Could you give a little more information about your situation? There might be a pattern you can use to update on a large scale. I would not have the same tag applied to all images, because that really doesn't help search engines understand the photo and wouldn't be useful to users who have vision impairments. If you don't have the time to do it, then hire someone to assign alt tags (virtual assistant). Screaming Frog will make it really easy to find all the image files.

Naturally in the perfect world, meaningful attributes should be added. Assuming you're a mere mortal with a limited number of hours in the day... the best short-term solution to this is going to be having the alt attribute applied but empty.
To my knowledge (happy to be pointed towards data showing otherwise), there's no real ranking difference between these two options. The reason I prefer to add a blank alt in this instance is because assistive technology (like screen readers for vision impaired users) are going to have a much better experience on your site this way.
If you have a blank alt, the screen readers will essentially ignore the image since they're going to read " ". On the other hand, if you don't have an alt attribute in the , it's going to read the source instead. Even a short img src is going to be cumbersome, especially if you have an image-heavy site!

Probably basic, but how to use image Title and Alt Text - and confusing advice from Moz!
I've been doing SEO on my business's site for years and have got good results. I've always used image Titles and Alt Text text. Our blog posts are image-intensive, often with 100-200 pictures (not surprising since we're photographers). For any given blog post, I've tended to have a uniform image Title for each image and then a more specialised Alt Text tag giving a description. A typical image on one of our blog posts would be like this: Image filename: wedding-photography-at-so-and-so-venue-001.jpg .... 002, 003 etc Image Title Attribute: Wedding Photography at So-And-So-Venue by Our-Company-Name - this would be the same for every image in the blog post. Alternative Text: Bride and groom exchanging vows during wedding ceremony at so-and-so-venue - this would be tailed for each image. So my question is - is this right? The Moz help page for image SEO is actually incorrect in one aspect: https://moz.com/ugc/10-tips-for-optimizing-your-images-for-search "Alt text (short for “alternative text”) is used to highlight the identity of an image when you hover over it with your mouse cursor. It also shows as text to all users when there are problems rendering the image." This is not the case. Hovering over the image in Firefox, Chrome, Edge and Opera ALL display the Image Title, NOT Alt Text. Thoughts?

Absolute vs. Relative Canonical Links
Hi Moz Community, I have a client using relative links for their canonicals (vs. absolute) Google appears to be following this just fine, but bing, etc. are still sending organic traffic to the non-canonical links. It's a drupal setup. Anyone have advice? Should I recommend that all canonical links be absolute? They are strapped for resources, so this would be a PITA if it won't make a difference. Thanks

How to add Canonical Tags on Opencart Products
Does anyone know how to add canonical tags to product pages in Opencart? Is this possible to do in htaccess? If so, how specifically should it be written in? Please do not post any links to other pages which reference generic canonical information as I've read them all and none help. I'm looking for an Opencart specific answer, or a way to do it in htaccess.

Creative Commons Images Good for SEO?
I've been looking at large image packages through iStock, Getty, Fotolia and 123RF, but before spending a bunch of money, I wanted to get some of your feedback on Creative Commons images. Should be worried that something found on Google Images > Search Tools > Usage Rights section can be used without issue or legal threats from the big image companies so long as they are appropriately referenced? AND will using these types of images and linking to the sources have any affect on SEO efforts or make the blog/website look spammy in Google's eyes because we need to link to the source? How are you using Creative Commons images and is there anything I should be aware of in the process of searching, saving, using, referencing, etc? Patrick

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.

Is it allowed to have different alt on same image on different pages?
Hi, I have images that match several different keywords and I wondered if I can give them different alts based on the page that they are displayed or will Google be angry with me? Thanks

Does City In Title Tag Inhibit Broader Reach?
I use our city/state in the majority of our title tags and consequently we do very well locallly for the majority of terms on our ecommerce site. I'm wondering however, if this "localized" optimization will inadvertently affect our keyword rankings outside of our city/state? If a keyword query does not include our city or state, would Google interpret our titles as less relevent and therefore move other results ahead of ours? The city/state is last in the string on the title: Blue Widgets - Our Company in City, State Thanks for any insight.

Why should your title and H1 tag be different?
Is it dangerous to have your H1 tag and your title the exact same thing? My thought was that it's not be the best use of space, but that it couldn't cause harm. What do you think?
