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 ;-)).

Google Image Search - Is there a way to influence the related icons at the top of the image search results?
Google recently added related icons at the top of the image search results page. Some of the icons may be unrelated to the search. Are there any best practices to influence what is positioned in the related image icons section? Thank you.

How (or if) to apply re canonical tags to Shopify?
Anyone familiar with Shopify will understand the problems of their directory structure. Every time you add a product to a 'collection' it essentially creates a duplicate. For example... https://www.domain.com/products/product-slim-regular-bikini may also appear as: https://www.domain.com/collections/all/products/product-slim-regular-bikini https://www.domain.com/collections/new-arrivals/products/product-slim-regular-bikini https://www.domain.com/collections/bikinis/products/product-slim-regular-bikini etc, etc It's not uncommon to have up to six duplicates of each product. So my question is twofold: Firstly, should I worry about this from an SEO point of view? I understand the desire to minimise potential duplicate content issues and also in focussing the 'juice' on just one page per product. But I also planned on trying to build the authority of the collection pages. If I request Google not to index the product pages which link off the collections, does this not devalue these collections pages? Secondly, I understand the correct way to fix these is using 'rel canonical' tags, but I'm not clear about HOW to actually do this. Shopify support has not been very helpful. They have provided two different instructions, so just added to the confusion (see below). Shopify instruction #1: Add the following to the theme.liquid file... <title><br />{{ page_title }}{% if current_tags %} – tagged "{{ current_tags | join: ', ' }}"{% endif %}{% if current_page != 1 %} – Page {{ current_page }}{% endif %}{% unless page_title contains shop.name %} – {{ shop.name }}{% endunless %}<br /></title>

{% if page_description %} {% endif %} Shopify instruction #2: Add the following to each individual product page... So, can anyone help clarify: The best strategic approach to this inherent SEO issue with Shopify (besides moving to another platform!)? and If 'rel canonical' tags is the way to go, exactly where and how to apply them?

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?

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.

Does a UTM tag influence the linkvalue?
Will Google value a link with a UTM tag the same as a clean link without a UTM tag? I should say that a UTM tag link is not a natural link so the linkvalue is zero. Anyone any idea how to look at this?

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?

What are Soft 404's and are they a problem
Hi, I have some old pages that were coming up in google WMT as a 404. These had links into them so i thought i'd do a 301 back to either the home page or to a relevant category or page. However these are now listed in WMT as soft 404's. I'm not sure what this means and whether google is saying it doesn't like this? Any advice welcomed.

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
