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 add no-follow tags to my widget links?
Matt Cutts recommended in a video in 2013 to add rel="nofollow" on widget links that link back to your website. Some background of my company: We're a software company for website chat. There's a 'powered by' link in our widgets that links back from our users' websites to our website. Currently these are all follow links. I checked out the links of our competitors, and it seems none of them have no follow on their widget backlinks. This, together with the fact that the video is quite old and information on this issue rather scarce, makes me doubt whether we should change our widget backlinks to no follow. Does anyone have thoughts on this?

Proper Title Tags for ecommerce
In terms of E-commerce title tags. We are a manufacturer of our own clothing products. We are new to the SEO landscape so if this question is an obvious answer, then i apologize for wasting any one times in advance. We Manufacture our own clothing. Each item has a name. The names are American womens names such as amanda or lori or jenniffer etc. When we create the title tag for them should we include the name of the item itself at the beginning or end. For example should it be Item Name - Keyword - Keyword - Brand Name(aka manufacturer) or Keyword - Keyword - Item Name - Brand Name (aka manufacturer) The reason we ask this is because we think it would be a waste to rank for actual American names such as Jennifer and Jessica. All that we have read on Moz suggests that it seems to be better to have pertinent keywords in the beginning of the title as opposed to the end. In terms of our brand name we already rank number 1 for every combination of our brand. So we would like to start picking up traffic for the different product types we sell and there respective synonyms. Not sure if i am making any sense. Sorry in advance, and any help is very very much appreciated.

Best Practices for Homepage Title Tag
Hi, I would like to know if there is any update about the best practices for the homepage title tag. I mean, a couple of years ago, it was still working placing main keywords in the homepage title tag. But since the last google SERP update, the number of characters that are being shown were reduced, and now we try to work with 55 and 56 characters. That has reduced our capacity of including many keywords on the title tag. Besides, search engines are smarter now to choose the correct inner page to show in SERP. But I am wondering if the Homepage Title should have a branded orientation or should include main keywords, cause it is still working that strategy. I would appreciatte any update in this issue. Thank you!

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 -
Exact match Title and H1 tags, and over optimization
Hi Mozzers - was just wondering whether matching H1 and Title tags are still OK, or whether there's an over optimization risk if they exact match?

Why is Google Displaying this image in the search results?
Hi i'm looking at advice on how to remove or change a particular image Google is displaying in the search results. I have attached a screenshot. From the first look of it, i assumed the image would be related and be on the dealers Google+ Local Page: https://plus.google.com/118099386834104087122/about?hl=en But there are no photos. The image seems to be coming from the website. Is there a way to stop Google from displaying this image or making them display a totally different image. Thanks, Chris XzfsnUy.png

Are pages with a canonical tag indexed?
Hello here, here are my questions for you related to the canonical tag: 1. If I put online a new webpage with a canonical tag pointing to a different page, will this new page be indexed by Google and will I be able to find it in the index? 2. If instead I apply the canonical tag to a page already in the index, will this page be removed from the index? Thank you in advance for any insights! Fabrizio

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.
