      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!

                  Redirect old image that has backlinks

                  Hi Moz Community! I'm doing an audit of a website and did a backlink analysis. In the backlink analysis, there is an image that has 66 backlinks but the image doesn't exist on the website anymore (it was on a website that was created in 2011 - 2 web launches ago).  I don't believe a 301 redirect will work for an image that doesn't exist anymore. How would I redirect the image URL (it's WordPress so we have a specific URL that other websites are linking to but get 404 errors) without going to each individual website and requesting they change the URL link? Any advice or recommendations would be great. 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?

                  Is it alright to repeat a keyword in the title tag?

                  I know at first glance, the answer to this is a resounding NO, that it can be construed as keyword stuffing,
                  but please hear me out. I am working on optimizing a client's website and although MOST of the title tags
                  can be optimized without repeating a keyword, occasionally I run into one where it doesn't read right if I
                  don't repeat the keyword. Here's an example: Current title:
                  Photoshop on the Cloud | Adobe Photoshop Webinars | Company Name What I am considering using as the optimized title:
                  Adobe Photoshop on the Cloud | Adobe Photoshop Webinars | Company Name Yes, I know both titles are longer than recommended. In both instances, only the company name gets
                  truncated so I am not too worried about that. So I guess what I want to know is this: Am I right in my original assumption that it is NEVER okay to
                  repeat keywords in a title tag or is it alright when it makes sense to do so?

                  Location.href vs href?

                  I just got off a Google Hangout with John Mueller and was left a little confused about his response to my question. If I have an internal link in a div like widgetwill it have the same SEO impact as widget John said that as you are unable to attribute a nofollow in an onclick event it would be treated as a naked link and would not pass pagerank but still be crawled. Can anyone confirm that I understood it correctly? If so should all my links that have such an onclickevent also have an html ahref in the too? Such as widget Many times it is more useful for the customer to click on any area of a large div and not just the link to get to the destination intended? Clarification on this subject would be very useful, there is nothing easily found online to confirm this. Thanks

                  Does a UTM tag influence the linkvalue?

                  Will Google value a link with a UTM tag the same as a clean link without a UTM tag? I should say that a UTM tag link is not a natural link so the linkvalue is zero. Anyone any idea how to look at this?

                  Best way to noindex an image?

                  Hi all, A client wanted a few pages noindexed, which was no problem using the meta robots noindex tag. However they now want associated images removed, some of which still appear on pages that they still want indexed. I added the images to their robots.txt file a few weeks ago (probably over a month ago actually) but they're all still showing when you do an image search. What's the best way to noindex them for good, and how do I go about implementing it? Many thanks, Steve

                  Would it be better to Start Over vs doing a Website Migration?

                  Hey guys /gals I have a question please.  I have a computer repair business that does extremely well in search and is on the front page of google for anything computer repair related. However, I am currently re-branding my company and have completely redesigned every aspect of the UI and the SEO Site structure as well as the fact that I have completely written vastly different content and different title tag lines and meta descriptions for each page. So basically when doing a migration we know that we want to keep our content, titles, headlines and meta descriptions the same as to not lose our page rank. Seeing that I have completely went against the grain in all directions on a much needed company re-branding and everything is completely different from the old site is it even worthwhile 301 redirecting my old urls to the new ones that would (best) correspond with the new? In the plainest English, would I do better at Ranking the New Website QUICKER without doing 301 redirects from the OLD to the NEW? In an EXTREME instance like what I have done, would the Domain Migration IMPEDED me ranking the new site seeing how nothing is the same? I have build a Rock solid SILO Site Architecture on the New site which is WordPress using the Thesis Framework and the old domain is built on JOOMLA 1.5 Thank fellas Marshall

                  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
