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!

Redirect old image that has backlinks
Hi Moz Community! I'm doing an audit of a website and did a backlink analysis. In the backlink analysis, there is an image that has 66 backlinks but the image doesn't exist on the website anymore (it was on a website that was created in 2011 - 2 web launches ago). I don't believe a 301 redirect will work for an image that doesn't exist anymore. How would I redirect the image URL (it's WordPress so we have a specific URL that other websites are linking to but get 404 errors) without going to each individual website and requesting they change the URL link? Any advice or recommendations would be great. Thanks!

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://outdoorsrank.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?

Multiple H2 tags
Is it advisable to use only one H2 tag? The template designs for some reason is ended up with multiple H2 tags, I realise if any think it's that each one is that are important and it is all relative. Just trying to assess if it's worth the time and effort to rehash the template. Has anyone done any testing or got any experience? Thanks

H2 vs. H3 Tags for Category Navigation
Hey, all. I have client that uses tags in the navigation for its blog. For example, tags might appear around "Library," "Recent Posts," etc. This is handled through their WordPress theme. This seems fairly standard, but I wonder whether tags are semantically appropriate. Since each blog post is fairly lengthy (about 500-1000 words) with multiple tags, would it be more appropriate to use tags for this menu navigation? Are we cutting into the effectiveness of our tags by using them for menu navigation? The navigation is certainly an important page element, and it structures content, so it seems that it should use some header tag. Anyways, your thoughts are greatly appreciated. I'm a content creator, not an SEO, so this is a bit out of my skillset.

How Many Images on 1 Page Are Acceptable
Example I have a page with a slideshow of 35 pictures. They are all unique pictures and relevant to the page, have unique alt text, though no captions or description surrounding the images. Page also has a lot of unique written content. Question: is this large nr of pictures potentially overwhelming for search engines and they may think it is spammy and it would be a safer bet to only keep the top 10 pictures on such page? I did review this great whiteboard Friday - http://outdoorsrank.com/blog/image-seo-basics-whiteboard-friday - and I noticed this at very end: "The other part, and I see this happen a lot especially with bigger clients, is when you put lots and lots of images on one page, like an image gallery, those pages tend to be very hard to get indexed. The reason for that is there's not a lot unique textual content. A lot of times it's just overwhelming to users. It doesn't provide a lot of benefit in a search result." My page has been indexed, but will ranking potentially be hurt and to play it safe I better reduce nr of pictures? I do understand the "do what is best for the user" scenario and that is what I am doing with a lot of amazing original pictures not found on any other website. However, with search engines we obviously have to consider how they operate as well. Thank you

Number of images on Google?
Hello here, In the past I was able to find out pretty easily how many images from my website are indexed by Google and inside the Google image search index. But as today looks like Google is not giving you any numbers, it just lists the indexed images. I use the advanced image search, by defining my domain name for the "site or domain" field: http://www.google.com/advanced_image_search and then Google returns all the images coming from my website. Is there any way to know the actual number of images indexed? Any ideas are very welcome! Thank you in advance.

Best way to noindex an image?
Hi all, A client wanted a few pages noindexed, which was no problem using the meta robots noindex tag. However they now want associated images removed, some of which still appear on pages that they still want indexed. I added the images to their robots.txt file a few weeks ago (probably over a month ago actually) but they're all still showing when you do an image search. What's the best way to noindex them for good, and how do I go about implementing it? Many thanks, Steve

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.
