Alt tag for src='blank.gif' on lazy load images
-
I didn't find an answer on a search on this, so maybe someone here has faced this before.
I am loading 20 images that are in the viewport and a bit below. The next 80 images I want to 'lazy-load'. They therefore are seen by the bot as a blank.gif file. However, I would like to get some credit for them by giving a description in the alt tag. Is that a no-no? If not, do they all have to be the same alt description since the src name is the same? I don't want to mess things up with Google by being too aggressive, but at the same time those are valid images once they are lazy loaded, so would like to get some credit for them.
Thanks! Ted

Martijn, thanks for your response. I could see Google saying that on a given page the same source image shouldn't have more than one alt description, and either penalizing such or just picking one of them or ignoring it altogether. It's the penalty I'm concerned with, of course. . But, I can also see that if they are seeing a blank.gif for the source and some code related to lazy loading they may go ahead and give credit to each alt as though a real src was loaded--and maybe even tying it to the real src image name for image search. Just looking for a bit more feedback from real-world experience first..
Has anyone else worked with this and determined if it is a pro or con?

Hi Ted, to be honest we do this and I don't see any big issues why we wouldn't do it. The placeholder image will probably get some more credits than usual. But the images we lazy load are loaded via JS and as Google says it can understand JS they should be able to get how we use it (too much assumptions I know, but I have more things to worry about ;-)).

Moved company 'Help Center' from Zendesk to Intercom, got lots of 404 errors. What now?
Howdy folks, excited to be part of the Moz community after lurking for years! I'm a few weeks into my new job (Digital Marketing at Rewind) and about 10 days ago the product team moved our Help Center from Zendesk to Intercom. Apparently the import went smoothly, but it's caused one problem I'm not really sure how to go about solving: https://help.rewind.io/hc/en-us/articles/*** is where all our articles used to sit https://help.rewind.io/*** is where all our articles now are So, for example, the following article has now moved as such: https://help.rewind.io/hc/en-us/articles/115001902152-Can-I-fast-forward-my-store-after-a-rewind- https://help.rewind.io/general-faqs-and-billing/frequently-asked-questions/can-i-fast-forward-my-store-after-a-rewind This has created a bunch of broken URLs in places like our Shopify/BigCommerce app listings, in our email drips, and in external resources etc. I've played whackamole cleaning many of these up, but these old URLs are still indexed by Google – we're up to 475 Crawl Errors in Search Console over the past week, all of which are 404s. I reached out to Intercom about this to see if they had something in place to help, but they just said my "best option is tracking down old links and setting up 301 redirects for those particular addressed". Browsing the Zendesk forms turned up some relevant-ish results, with the leading recommendation being to configure javascript redirects in the Zendesk document head (thread 1, thread 2, thread 3) of individual articles. I'm comfortable setting up 301 redirects on our website, but I'm in a bit over my head in trying to determine how I could do this with content that's hosted externally and sitting on a subdomain. I have access to our Zendesk admin, so I can go in and edit stuff there, but don't have experience with javascript redirects and have read that they might not be great for such a large scale redirection. Hopefully this is enough context for someone to provide guidance on how you think I should go about fixing things (or if there's even anything for me to do) but please let me know if there's more info I can provide. Thanks!

Changing title tags - any potential issues?
Hello all, I am planning to change the title tags throughout a site and am vaguely aware (perhaps wrongly!) that changing title tags across a site is a risk factor - can be a spam flag if changes (to a specific title tag) are implemented too regularly, for example. Would you change title tags across a site in one go, or implement changes gradually - to avoid any risk of upsetting Google. Do you have any insights/tips on the implementation of title tag changes?

If Robots.txt have blocked an Image (Image URL) but the other page which can be indexed has this image, how is the image treated?
Hi MOZers, This probably is a dumb question but I have a case where the robots.tags has an image url blocked but this image is used on a page (lets call it Page A) which can be indexed. If the image on Page A has an Alt tags, then how is this information digested by crawlers? A) would Google totally ignore the image and the ALT tags information? OR B) Google would consider the ALT tags information? I am asking this because all the images on the website are blocked by robots.txt at the moment but I would really like website crawlers to crawl the alt tags information. Chances are that I will ask the webmaster to allow indexing of images too but I would like to understand what's happening currently. Looking forward to all your responses 🙂 Malika

How Many Images on 1 Page Are Acceptable
Example I have a page with a slideshow of 35 pictures. They are all unique pictures and relevant to the page, have unique alt text, though no captions or description surrounding the images. Page also has a lot of unique written content. Question: is this large nr of pictures potentially overwhelming for search engines and they may think it is spammy and it would be a safer bet to only keep the top 10 pictures on such page? I did review this great whiteboard Friday - http://moz.rainyclouds.online/blog/image-seo-basics-whiteboard-friday - and I noticed this at very end: "The other part, and I see this happen a lot especially with bigger clients, is when you put lots and lots of images on one page, like an image gallery, those pages tend to be very hard to get indexed. The reason for that is there's not a lot unique textual content. A lot of times it's just overwhelming to users. It doesn't provide a lot of benefit in a search result." My page has been indexed, but will ranking potentially be hurt and to play it safe I better reduce nr of pictures? I do understand the "do what is best for the user" scenario and that is what I am doing with a lot of amazing original pictures not found on any other website. However, with search engines we obviously have to consider how they operate as well. Thank you

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
