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!

Should I disable the indexing of tags in Wordpress?
Hi, I have a client that is publishing 7 or 8 news articles and posts each month. I am optimising selected posts and I have found that they have been adding a lot of tags (almost like using hashtags) . There are currently 29 posts but already 55 tags, each of which has its own archive page, and all of which are added to the site map to be indexed (https://sykeshome.europe.sykes.com/sitemap_index.xml). I came across an article (https://crunchify.com/better-dont-use-wordpress-tags/) that suggested that tags add no value to SEO ranking, and as a consequence Wordpress tags should not be indexed or included in the sitemap. I haven't been able to find much more reliable information on this topic, so my question is - should I get rid of the tags from this website and make the focus pages, posts and categories (redirecting existing tag pages back to the site home page)? It is a relatively new websites and I am conscious of the fact that category and tag archive pages already substantially outnumber actual content pages (posts and news) - I guess this isn't optimal. I'd appreciate any advice. Thanks wMfojBf

Images on their own page?
Hi Mozers, We have images on their own separate pages that are then pulled onto content pages. Should the standalone pages be indexable? On the one hand, it seems good to have an image on it's own page, with it's own title. On the other hand, it may be better SEO for crawler to find the image on a content page dedicated to that topic. Unsure. Would appreciate any guidance! Yael

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.

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?

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 -
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

Wildcard Redirects & Canonical Tags
I have an interesting situation. Current URLs Example1: www.domain.com/red-widgets-cid-1234.html
