      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!

                  Is single H1 tag still best practice?

                  Hi Guys, Is having a single h1 tag still best practice for SEO? Guessing multiple h1 tags dilute the value of the tag and keywords within the tag. Thoughts? Cheers.

                  Too many Tags and Categories what should I do to clean this up?

                  Hello, Everyone! I am trying to do a clean up for one of my client sites. I'm noticing that the Categories and tags are way out of hand. It looks like random tags and categories were just added because they could be added. Are all of these tags and categories contributing to duplicate content? And if so What method should I go about to cleaning this up? The only thing that seems logical to me is rel=canonical. Thank you so much!

                  Partial duplicate content and canonical tags

                  Hi - I am rebuilding a consumer website, and each product page will contain a unique product image, and a sentence or two about the product (and we tend to use a lot of the same words in different ways across products). I'd like to have a tabbed area below the product info that talks about the overall product line, and this content would be duplicate across all the product pages (a "Why use our products" type of thing). I'd have this duplicate content also living on its own URL's so they can be found alone in the SERP's. Question is, do I need to add the canonical tag to this page, since there's partial duplicate content on the product pages? And if I did that, would my product pages go un-indexed?? I understand how to handle completely duplicated content, it's the partial duplicate that I'm having difficulty figuring out.

                  Canonical tag - but Title and Description are slightly different

                  I am building a new SEO site with a "Silo" / Themed architecture.  I have a travel website selling hotel reservations.  I list a hotel page under a city page - example, www.abc.com/Dallas/Hilton.html   Then I use that same property under a segment within the city - example www.abc.com/Dallas/Downtown/Hilton.html, so there are two URLs with the same content Both pages are identical, except I want to customize the Title and Description.  I want to customize the title and description to build a consistent theme - for example the /Downtown/Hilton page will have the words "Near Downtown" in the Title and Description, while the primary city Hilton page will not.  So I have two questions about this. First, is it okay to use a canonical tag if the Title and Description are slightly different?  Everything else is identical. If so, will Google crawl and comprehend the unique Title and Description on the "Downtown" silo? I want Google to see that I have several "supporting" pages to my main landing page(s).  I want to present to Google 5 supporting pages in each silo that each has a supporting keyword theme.  But I'm not sure if Google will consider content of pages that point to a different page using the canonical tag. Please see this supporting example:  http://d.pr/i/aQPv Thanks for your insights. Rob

                  What is the point of having images clickable loading to their own page?

                  Hello, Noticed a lot of sites, usually wordpress (seems to be the default) have the images in their posts clickable that load to their own page, showing just the image, usually a .jpg page. I know these pages seem to be easily indexed into google image search and can drive traffic to those specific pages... My questions are... 1. What is the point of driving traffic to a page that is just the image, there are no links to other pages, no ads, nothing... 2. can you redirect these .jpg pages to the actual post page? I ask because on google image search, there are 3 links to click (website, image link, image page), when you click to view the image, it loads the .jpg page, why not have that .jpg redirect to the real content page that has ads and also has other links. Is this white-hat? 3. Do these pages with just images have any negative effect on optimization since they are just images, no content? 4. Can you monetize these .jpg pages? 5. What is the best practice? I understand there is value in traffic, but what is the point of image traffic if I can't monetize those pages?

                  How to See Image Metadata?

                  We sell 1000s of audiobooks and get our cover images and descriptions from the publisher’s sites. When I download a cover image such as this one (http://www.audiobooksonline.com/media/Alex-Cross-Run-James-Patterson.jpg)
                  I always rename and re-size it before installing at our Web store. Would this process result in any publisher’s metadata in the image we use at our Web store and/or anything else Google would not like?
                  Is there an online utility that would allow me to see metadata in our images?

                  H2 Tag Backlink - is this safe?

                  I have found that my site is getting a link from a good site, but my concern is that the link is in a H2 tag in the footer of the front page of the site Would getting a link from a site wrapped in H2 tags be safe? The anchor is my sites brand name

                  Rel=canonical tag on original page?

                  Afternoon All,
                  We are using Concrete5 as our CMS system, we are due to change but for the moment we have to play with what we have got. Part of the C5 system allows us to attribute our main page into other categories, via a page alaiser add-on. But what it also does is create several url paths and duplicate pages depending on how many times we take the original page and reference it in other categories. We have tried C5 canonical/SEO add-on's but they all seem to fall short. We have tried to address this issue in the most efficient way possible by using the rel=canonical tag. The only issue is the limitations of our cms system. We add the canonical tag to the original page header and this will automatically place this tag on all the duplicate pages and in turn fix the problem of duplicate content. The only problem is the canonical tag is on the original page as well, but it is referencing itself, effectively creating a tagging circle. Does anyone foresee a problem with the canonical tag being on the original page but in turn referencing itself? What we have done is try to simplify our duplicate content issues. We have over 2500 duplicate page issues because of this aliasing add-on and want to automate the canonical tag addition, rather than go to each individual page and manually add this tag, so the original reference page can remain the original. We have implemented this tag on one page at the moment with 9 duplicate pages/url's and are monitoring, but was curious if people had experienced this before or had any thoughts?
