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 ;-)).

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!

Probably basic, but how to use image Title and Alt Text - and confusing advice from Moz!
I've been doing SEO on my business's site for years and have got good results. I've always used image Titles and Alt Text text. Our blog posts are image-intensive, often with 100-200 pictures (not surprising since we're photographers). For any given blog post, I've tended to have a uniform image Title for each image and then a more specialised Alt Text tag giving a description. A typical image on one of our blog posts would be like this: Image filename: wedding-photography-at-so-and-so-venue-001.jpg .... 002, 003 etc Image Title Attribute: Wedding Photography at So-And-So-Venue by Our-Company-Name - this would be the same for every image in the blog post. Alternative Text: Bride and groom exchanging vows during wedding ceremony at so-and-so-venue - this would be tailed for each image. So my question is - is this right? The Moz help page for image SEO is actually incorrect in one aspect: https://moz.com/ugc/10-tips-for-optimizing-your-images-for-search "Alt text (short for “alternative text”) is used to highlight the identity of an image when you hover over it with your mouse cursor. It also shows as text to all users when there are problems rendering the image." This is not the case. Hovering over the image in Firefox, Chrome, Edge and Opera ALL display the Image Title, NOT Alt Text. Thoughts?

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.

H Tags in Menu
Hi I am checking the H2 tags on this page https://www.key.co.uk/en/key/dollies-load-movers-door-skates I have noticed my dev team have implemented H2's on the categories in the menu. Will this completely confuse Google as to what that page is about? In my opinion those links shouldn't be heading tags at all

Combining images with text as anchor text
Hello everyone, I am working to create sub-category pages on our website virtualsheetmusic.com, and I'd like to have your thoughts on using a combination of images and text as anchor text in order to maximize keyword relevancy. Here is an example (I'll keep it simple): Let's take our violin sheet music main category page located at /violin/, which includes the following sub-categories: Christmas Classical Traditional So, the idea is to list the above sub-categories as links on the main violin sheet music page, and if we had to use simple text links, that would be something like: Christmas
Intermediate & Advanced SEO | | fablau
Classical
Traditional Now, since what we really would like to target are keywords like: "christmas violin sheet music" "classical violin sheet music" "traditional violin sheet music" I would be tempted to make the above links as follows: Christmas violin sheet music
Classical violin sheet music
Traditional violin sheet music But I am sure that would be too much overwhelming for the users, even if the best CSS design were applied to it. So, my idea would be to combine images with text, in a way to put those long-tail keywords inside the image ALT tag, so to have links like these: Christmas
Classical
Traditional That would allow a much easier way to work the UI , and at the same time keep relevancy for each link. I have seen some of our competitors doing that and they have top-notch results on the SEs. My questions are: 1. Do you see any negative effect of doing this kind of links from the SEO standpoint? 2. Would you suggest any better way to accomplish what I am trying to do? I am eager to know your thoughts about this. Thank you in advance to anyone!1 -
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

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.
