Null Alt Image Tags vs Missing Alt Image Tags
-
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!

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.

Description vs meta description
I have an e-commerce website and am trying to create product category pages. I am under the impression that Description is the text that would appear under the title on a google search and I believe the meta description is just what google reads? Is having BOTH important or just description? Is it ok to duplicate the description for the meta description? I know its not good to duplicate descriptions on other products and pages.

Images Not Indexing? (Nudity Warning!) - Before & After Photos
One of our clients is in the Cosmetic Surgery business (bodevolve.com) and individuals most likely to purchase a cosmetic procedure only search for 2 things....'**before & after photos' and 'cost'. ** That being said we've worked extremely hard to optimize all 500+ before and after photos. And to our great disappointment, they still aren't being indexed...we are testing a few things but any feedback would be greatly appreciated! All photos are in the 'attachment' sitemap: http://bodevolve.com/sitemap_index.xml I'm also testing a few squeeze pages like this one: http://bodevolve.com/tummy-tuck-before-and-after-photos/ Thanks so much, Brit

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?

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! B0 -

Should I Allow Blog Tag Pages to be Indexed?
I have a wordpress blog with settings currently set so that Google does not index tag pages. Is this a best practice that avoids duplicate content or am I hurting the site by taking eligible pages out of the index?
