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 ;-)).

After hack and remediation, thousands of URL's still appearing as 'Valid' in google search console. How to remedy?
I'm working on a site that was hacked in March 2019 and in the process, nearly 900,000 spam links were generated and indexed. After remediation of the hack in April 2019, the spammy URLs began dropping out of the index until last week, when Search Console showed around 8,000 as "Indexed, not submitted in sitemap" but listed as "Valid" in the coverage report and many of them are still hack-related URLs that are listed as being indexed in March 2019, despite the fact that clicking on them leads to a 404. As of this Saturday, the number jumped up to 18,000, but I have no way of finding out using the search console reports why the jump happened or what are the new URLs that were added, the only sort mechanism is last crawled and they don't show up there. How long can I expect it to take for these remaining urls to also be removed from the index? Is there any way to expedite the process? I've submitted a 'new' sitemap several times, which (so far) has not helped. Is there any way to see inside the new GSC view why/how the number of valid URLs in the indexed doubled over one weekend?

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!

Does Google Read URL's if they include a # tag? Re: SEO Value of Clean Url's
An ECWID rep stated in regards to an inquiry about how the ECWID url's are not customizable, that "an important thing is that it doesn't matter what these URLs look like, because search engines don't read anything after that # in URLs. " Example http://www.runningboards4less.com/general-motors#!/Classic-Pro-Series-Extruded-2/p/28043025/category=6593891 Basically all of this: #!/Classic-Pro-Series-Extruded-2/p/28043025/category=6593891 That is a snippet out of a conversation where ECWID said that dirty urls don't matter beyond a hashtag... Is that true? I haven't found any rule that Google or other search engines (Google is really the most important) don't index, read, or place value on the part of the url after a # tag.

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.com/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

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
Intermediate & Advanced SEO | | bjs2010
"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 -
