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!

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://cloudz.click/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?

Should I add no-follow tags to my widget links?
Matt Cutts recommended in a video in 2013 to add rel="nofollow" on widget links that link back to your website. Some background of my company: We're a software company for website chat. There's a 'powered by' link in our widgets that links back from our users' websites to our website. Currently these are all follow links. I checked out the links of our competitors, and it seems none of them have no follow on their widget backlinks. This, together with the fact that the video is quite old and information on this issue rather scarce, makes me doubt whether we should change our widget backlinks to no follow. Does anyone have thoughts on this?

Will disallowing URL's in the robots.txt file stop those URL's being indexed by Google
I found a lot of duplicate title tags showing in Google Webmaster Tools. When I visited the URL's that these duplicates belonged to, I found that they were just images from a gallery that we didn't particularly want Google to index. There is no benefit to the end user in these image pages being indexed in Google. Our developer has told us that these urls are created by a module and are not "real" pages in the CMS. They would like to add the following to our robots.txt file Disallow: /catalog/product/gallery/ QUESTION: If the these pages are already indexed by Google, will this adjustment to the robots.txt file help to remove the pages from the index? We don't want these pages to be found.

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?

508 compliance vs good SEO re: Image alt tags
I'm currently in debate with our 508 compliance team over the use of alt tags on images. For SEO, it is best practice to use alt tags so that readers can tell what the image represents. However, they are arguing that these images should NOT have alt text as it doesn't add anything to the disability screen reader as the image text would be repetitive with the text on the page. I feel they are taking the "decorative" image concept in 508 compliance too far. It's intention is for images for bullets, etc that truly are decorative in nature and add no benefit to the reader. What is the communities thoughts on this? Have you ever run into scenario where 508 is attempting to ruin SEO? Usually the 2 play nicely.

Adding a Canonical Tag to each page referencing itself?
Hey Mozers! I've noticed that on www.Zappos.com they have a Canonical tag on each page referencing it self. I have heard that this is a popular method but I dont see the point in canon tagging a page to its self. Any thoughts?

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?
