      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!

                  Google Indexing Of Pages As HTTPS vs HTTP

                  We recently updated our site to be mobile optimized.  As part of the update, we had also planned on adding SSL security to the site.  However, we use an iframe on a lot of our site pages from a third party vendor for real estate listings and that iframe was not SSL friendly and the vendor does not have that solution yet.  So, those iframes weren't displaying the content. As a result, we had to shift gears and go back to just being http and not the new https that we were hoping for. However, google seems to have indexed a lot of our pages as https and gives a security error to any visitors.  The new site was launched about a week ago and there was code in the htaccess file that was pushing to www and https.  I have fixed the htaccess file to no longer have https. My questions is will google "reindex" the site once it recognizes the new htaccess commands in the next couple weeks?

                  Ranking dropped after changing title tag

                  I recently changed my company's site homepage title tag to make it start with our target keyword. The page was originally at page #7 or #8 and dropped to page #17 directly after I changed the page title. Is this normal? Is it's a temporary drop or should I change it back to the previous title.

                  Onsite SEO vs Offsite SEO

                  Hey I know the importance of both onsite & offsite, primarily with regard to outreach/content/social. One thing I am trying to determine at the moment, is how much do I invest in offsite. My current focus is to improve our onpage content on product pages, which is taking some time as we have a small team. But I also know our backlinks need to improve. I'm just struggling on where to spend my time. Finish the onsite stuff by section first, or try to do a bit of both onsite/offsite at the same time?

                  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

                  Noindex : Do Follow or No Follow Tags?

                  Hello, I have a website with tags (which have the noindex tag) on each article post. I've been told that I should noindex/nofollow these tag pages, because they are getting link juice passed to them, and since they aren't getting indexed, it's wasting link juice to those pages, when the link juice could be passed to a page that is actually getting indexed. What are your thoughts on this? Also, what would be the point to noindex/follow a page, if you are noindexing that page? Isn't it just wasting link juice? What is the proper SEO way to optimize tags.

                  Is there a limit to images file names?

                  Hi, I have an eCommerce site with hundreds of product images. For management reasons files are named in length to have the product details in them.
                  Is there a limit for a filename length before it is considered ambiguous or spammy etc.?
                  (it usually ranges 50-70 chars). Thanks

                  Urls missing from product_cat sitemap

                  I'm using Yoast SEO plugin to generate XML sitemaps on my e-commerce site (woocommerce). I recently changed the category structure and now only 25 of about 75 product categories are included. Is there a way to manually include urls or what is the best way to have them all indexed in the sitemap?

                  Accidently added a nofollow, noindex tag and then...

                  Hey guys, My first post here and ironically highlights a ridiculously stupid mistake! Ok, here's the deal... I started building links to one of my new page on a fairly good, old site (DA = >35). Before starting to build links, I added fresh new content, and while doing that, I accidentally added a "nofollow" and "noindex" tag to the page! Guess what, google DID de-index the page ! So the questions is (and YES, I did change the meta tags): Will google re-index the page with some good linking? Will it treat the page as a new, fresh page even though it was present for over a year? I had already started link building to that page, and now technically the links are pointing to a page that does not exist in the index, so once it does get re-indexed, will Google FLAG it as having too many links? Would I be ranking it as a new page? Will its previous ranking (for very few keywords) will come back? Thanks and Regards, Amod
