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!

Htaccess - Redirecting TAG or Category pages
Hello Fellow Moz's, We have an issue redirecting some /TAG and /Category pages to inner pages. As an example we use: RedirectMatch 301 /category/Sample-Category(.*) https://OurDomain.com.au/New-Page//$1 That works well. The issue is we have other categories and tags that are named similar to /Sample-Category As an example, if we try to redirect /Sample-Category-1 to /New-Page-1 - it will not work, and redirects to /New-Page I assume this is because /Sample-Category is already being redirected, so anything after /Sample-Category like -1 or -2 or -3 etc, will not be recognized. Anyone know of a workaround?

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

Combining images with text as anchor text
Hello everyone, I am working to create sub-category pages on our website virtualsheetmusic.com, and I'd like to have your thoughts on using a combination of images and text as anchor text in order to maximize keyword relevancy. Here is an example (I'll keep it simple): Let's take our violin sheet music main category page located at /violin/, which includes the following sub-categories: Christmas Classical Traditional So, the idea is to list the above sub-categories as links on the main violin sheet music page, and if we had to use simple text links, that would be something like: Christmas
Intermediate & Advanced SEO | | fablau
Classical
Traditional Now, since what we really would like to target are keywords like: "christmas violin sheet music" "classical violin sheet music" "traditional violin sheet music" I would be tempted to make the above links as follows: Christmas violin sheet music
Classical violin sheet music
Traditional violin sheet music But I am sure that would be too much overwhelming for the users, even if the best CSS design were applied to it. So, my idea would be to combine images with text, in a way to put those long-tail keywords inside the image ALT tag, so to have links like these: Christmas
Classical
Traditional That would allow a much easier way to work the UI , and at the same time keep relevancy for each link. I have seen some of our competitors doing that and they have top-notch results on the SEs. My questions are: 1. Do you see any negative effect of doing this kind of links from the SEO standpoint? 2. Would you suggest any better way to accomplish what I am trying to do? I am eager to know your thoughts about this. Thank you in advance to anyone!1 -
If Robots.txt have blocked an Image (Image URL) but the other page which can be indexed has this image, how is the image treated?
Hi MOZers, This probably is a dumb question but I have a case where the robots.tags has an image url blocked but this image is used on a page (lets call it Page A) which can be indexed. If the image on Page A has an Alt tags, then how is this information digested by crawlers? A) would Google totally ignore the image and the ALT tags information? OR B) Google would consider the ALT tags information? I am asking this because all the images on the website are blocked by robots.txt at the moment but I would really like website crawlers to crawl the alt tags information. Chances are that I will ask the webmaster to allow indexing of images too but I would like to understand what's happening currently. Looking forward to all your responses 🙂 Malika

Is it worth creating an Image Sitemap?
We've just installed the server side script 'XML Sitemaps' on our eCommerce site. The script gives us the option of (easily) creating an image sitemap but I'm debating whether there is any reason for us to do so. We sell printer cartridges and so all the images will be pretty dry (brand name printer cartridge in front of a box being a favourite). I can't see any potential customers to search for an image as a route in to the site and Google appears to be picking up our images on it's own accord so wonder if we'll just be crawling the site and submitting this information for no real reason. From a quality perspective would Google give us any kind of kudos for providing an Image Sitemap? Would it potentially increase their crawl frequency or, indeed, reduce the load on our servers as they wouldn't have to crawl for all the images themselves?

Why Google isn't indexing my images?
Hello, on my fairly new website Worthminer.com I am noticing that Google is not indexing images from my sitemap. Already 560 images submitted and Google indexed only 3 of them. Altough there is more images indexed they are not indexing any new images, and I have no idea why. Posts, categories and other urls are indexing just fine, but images not. I am using Wordpress and for sitemaps Wordpress SEO by yoast. Am I missing something here? Why Google won't index my images? Thanks, I appreciate any help, David xv1GtwK.jpg

Should I redirect images when I migrate my site
We are about to migrate a large website with a fair few images (20,000). At the moment we include images in the sitemap.xml so they are indexed by Google and drive traffic (not sure how I can find out how much though). Current image slugs are like:
Intermediate & Advanced SEO | | ArchMedia
http://website.com/assets/images/a2/65680/thumbnails/638x425-crop.jpg?1402460458 Like on the old site, images on the new website will also have unreadable cache slugs, like:
http://website.com/site_media/media/cache/ce/7a/ce7aeffb1e5bdfc8d4288885c52de8e3.jpg All content pages on the new site will have the same slugs as on the old site. Should I go through the trouble of redirecting all these images?0 -
Microsites: Subdomain vs own domains
I am working on a travel site about a specific region, which includes information about lots of different topics, such as weddings, surfing etc. I was wondering whether its a good idea to register domains for each topic since it would enable me to build backlinks. I would basically keep the design more or less the same and implement a nofollow navigation bar to each microsite. e.g.
Intermediate & Advanced SEO | | kinimod
weddingsbarcelona.com
surfingbarcelona.com or should I rather go with one domain and subfolders: barcelona.com/weddings
barcelona.com/surfing I guess the second option is how I would usually do it but I just wanted to see what are the pros/cons of both options. Many thanks!0
