      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!

                  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
                  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!

                  Putting Dates In Title Tag

                  Hi, I have a site were I write previews for sports match ups.  I notice when I don't put the date in the title I rank much better for specific keywords.  I also noticed that most people don't really put in the date when they do the search anyways, especially since google does a good job of showing the most recent pages anyways. The only reason I continue to put the date is because of this whole idea of not having page titles that are duplicate.  So many of our games will be Team A vs Team B Preview, and Im worried that the term "preview" will become so repetitive that google may not like it.  Any tips or ideas on how to approach this issue best? Thanks!

                  Should I use **tags or h1/h2 tags for article titles on my homepage**

                  I recently had an seo consultant recommend using tags instead of h1/h2 tags for article titles on the homepage of my news website and category landing pages. I've only seen this done a handful of times on news/editorial websites. For example: http://www.muscleandfitness.com/ Can anyone weigh in on this?

                  Lowercase VS. Uppercase Canonical tags?

                  Hi MOZ, I was hoping that someone could help shed some light on an issue I'm having with URL structure and the canonical tag. The company I work for is a distributor of electrical products and our E-commerce site is structured so that our URL's (specifically, our product detail page URL's) include a portion (the part #) that is all uppercase (e.g: buy/OEL-Worldwide-Industries/AFW-PG-10-10). The issue is that we have just recently included a canonical tag in all of our product detail pages and the programmer that worked on this project has every canonical tag in lowercase instead of uppercase.  Now, in GWT, I'm seeing over 20,000-25,000 "duplicate title tags" or "duplicate descriptions". Is this an issue?  Could this issue be resolved by simply changing the canonical tag to reflect the uppercase URL's?  I'm not too well versed in canonical tags and would love a little insight. Thanks!

                  Meta NoIndex tag and Robots Disallow

                  Hi all, I hope you can spend some time to answer my first of a few questions 🙂 We are running a Magento site - layered/faceted navigation nightmare has created thousands of duplicate URLS! Anyway, during my process to tackle the issue, I disallowed in Robots.txt anything in the querystring that was not a p (allowed this for pagination). After checking some pages in Google, I did a site:www.mydomain.com/specificpage.html and a few duplicates came up along with the original with
                  "There is no information about this page because it is blocked by robots.txt" So I had added in Meta Noindex, follow on all these duplicates also but I guess it wasnt being read because of Robots.txt. So coming to my question. Did robots.txt block access to these pages? If so, were these already in the index and after disallowing it with robots, Googlebot could not read Meta No index? Does Meta Noindex Follow on pages actually help Googlebot decide to remove these pages from index? I thought Robots would stop and prevent indexation? But I've read this:
                  "Noindex is a funny thing, it actually doesn’t mean “You can’t index this”, it means “You can’t show this in search results”. Robots.txt disallow means “You can’t index this” but it doesn’t mean “You can’t show it in the search results”. I'm a bit confused about how to use these in both preventing duplicate content in the first place and then helping to address dupe content once it's already in the index. Thanks! B

                  HTML5 Nav Tag Issue - Be Aware

                  In checking my internal links with GWT, it is apparent that links within the nav tag in HTML5 are discounted by Google as "internal links" This could have major repercussions for designing your internal link structure for SEO purposes. I was surprised to see this result, as I have never seen it discussed. Anyone else notice this, or have any alternative views?

                  Site Architecture: Cross Linking vs. Siloing

                  I'm curious to know what other mozzers think about silo's... Can we first all agree that a flat site architecture is the best practice? Relevant pages should be grouped together. Shorter, broader and (usually) therefore higher volume keywords should be towards the top of each category. Navigation should flow from general to specific. Agreed? As Google say's on page 10 of their SEO Starter Guide, "you should think about how visitors will go from a general page (your root page) to a page containing more specific content ." OK, we all agree so far, right? Great! Enter my question: Bruce Clay (among others) seem to recommend siloing as a best practice. While Richard Baxter (and many others @ SEOmoz), seem to view silos as a problem. Me? I've practiced (relevant) internal cross linking, and have intentionally avoided siloing in almost all cases. What about you? Is there a time and place to use silos? If so, when and where? If not, how do we rectify the seemingly huge differences of opinions between expert folks such as Baxter and Clay?
