Is it a legal requirement for a website to have alt tags for all images?
-
Someone told me it is a legal requirement for a website to have alt tags on all of their images. Is this right? Or is this bad for SEO?
-
I think it depends on where the website is - in the UK, it is a requirement to make sure that disabled people have the same or as similar as possible experience online as anyone else. Alt tags make it easier for the blind (amongst other groups of people) to understand the context of a website - a picture tells a thousand words and all that!
I personally think its worth doing (though there are some missing on my site for various reasons) as even if you don't believe any of your visitors are using screen readers I bet some of them actually are.
In the late 90s/early 00s the well known British supermarket, Tesco redeveloped their website to be accessible (not just Alt tags), and saw a staggering increase in sales and conversions as a result. I can't remember the exact figure but it was pretty impressive.
So I guess I'm saying there are other reasons besides SEO and legal to implement accessibility features into your site - fundamental business reasons! Making more money. (though of course the cost must be weighed up against the benefit just like anything else).

Most SEOs I know don't know this but yes, some sites are legally required to have alt text. However, they are government sites, those who accept federal dollars or anyone who's tied to the Electronic and Information Technology Accessibility Standards under section 508 of the Rehabilitation Act of 1973, (“508 Standards”).
You can read more about these accessibility requirements here: http://www.access-board.gov/guidelines-and-standards/communications-and-it/about-the-ict-refresh/proposed-rule/ii-executive-summary
While alt text is not required for a standard commercial or informational business (as far as I know), it does help with long tail traffic, though not always the kind that converts. I would want alt text on a clothing store's images but not necessarily on a page about eye surgery. (People are unlikely to hire a doctor based on a nice photo.)

Why are my blog slideshow images not indexed?
I'm managing a design blog hosted on WordPress. Each "design project" article includes a slideshow with additional images (and captions) for the project - these are images and text not found in the article itself. Every slide has the same page path as the article, but a different query param at the end. So if the article is /article the first slide would be /article?slide=1 for example. I'm having two issues: The slideshow images don't seem to be getting indexed. Screaming Frog reports duplicate meta descriptions and title tags for each slideshow page (same meta as article). I want to do what's best overall from an SEO perspective. Having the slideshow images show in Google image search is a must. And having the captions indexed might help too? But I want the Google image results linking to the article and not the individual slideshow pages. And I don't want duplicate meta issues. What's the best thing to do? Submit a sitemap that lists both article and slideshow images? "Rel canonical" the param'd slideshow urls to the base article url (not sure this makes total sense, since slide content is different from the article)? Get rid of slideshow altogether and put images in body? Some combo of these? Hopefully this makes sense. Any thoughts appreciated!

Moving Images to Subdomain: SEO Impacts
For sever work- load enhancements we are planning to move our images to a sub-domain. so the files would be located at something like images.domain.com Rather than domain.com/images/ We are a large Ecommerce site so we have a lot of images. These will be self hosted so we are not using a CDN. I'm hoping someone has done the same and if there were any steps they had wished they had taken before making the move/ if they noticed any traffic impacts things like that.

Google images not showing on SERP
Hi, I recently noticed that after a specific name search, Google images on the 'Web' SERP are no longer showing up. About a month ago, there were atleast 4-5 headshots of this particular person showing up whenever his name was searched. Now no images are showing, just the ten organic links and two links from adwords campaign we have going. The images are still optimized and some are even from editorial sites. Does anyone know what may have caused the images to disappear and what we can do to bring them back to the main SERP? (Not sure if it matters but we are in Canada) Thanks

Metadata stored in images read by search engines?
Does anyone know if metadata stored in images is read by search engines?My company stores images in digital asset management systems and metadata keyword tags are added to the images, so they can easily be found within the system. Since these keywords are stored in the image file, I was wondering if search engines can read them once the image is placed on the website, but I'm not finding any evidence of this in my research.

Local SEO: How to optimize for multiple cities on website
Hi, I couldn't find any reference to this, so if the answer is already here, I would appreciate a link to the answer. That said, my question is this: When a local business services a large geographic area, I wanted to know how to optimize for the multiple towns? I already have the main city in my title tags, but there are at least 40 areas that surround this town. Should I have a "Services Area" page, and place all the towns there, or should they all be in the footer? I saw this one guy - in the same niche who put all the towns in his meta keyword section - but I think that's incorrect, especially since Google doesn't look at that particular meta tag. Any help would be appreciated.

Dynamic image serving SEO
We often use images from a dynamic image server, to cater for image asset management, multiple sizes etc. Similar to Adobe's Scene7, although that came out after we chose our product. So widgets.com may have all its images with a URL like myimageserver.com?src=widgets/catalogue/productname.jpg;width=100;height=100;angle=90, instead of widgets.com/images/productname.jpg. A potential client wants to capitalise on traffic from Google image search. We could build an image sitemap, listing the images on each page. What should we place in the image:loc field? The code: myimageserver.com?src=widgets/catalogue/productname.jpg;width=100;height=100;angle=90 Apparently we have to verify the hosting site in Webmaster Tools, but I can't see where. I have a single Webmaster Tools account, where most of our sites are defined. Would I have to verify it for each site using the dynamic imaging program? Love to hear from anyone with solutions for getting images indexed when they are hosted at third-party dynamic imaging programs.
