      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 ;-)).

            Is it best practice to have a canonical tags on all pages

            The website I'm working on has no canonical tags. There is duplicate content so rel=canonicals need adding to certain pages but is it best practice to have a tag on every page ?

            Should I redirect a domain we control but which has been labeled 'toxic' or just shut it down?

            Hi Mozzers: We recently launched a site for a client which involved bringing in and redirecting content which formerly had been hosted on different domains. One of these domains still existed and we have yet to bring over the content from it. It has also been flagged as a suspicious/toxic backlink source to our new domain. Would I be wise to redirect this old domain or should I just shut it down? None of the pages seem to have particular equity as link sources. Part of me is asking myself 'Why would we redirect a domain deemed toxic, why not just shut it down.' Thanks in advance, dave

            Proper Title Tags for ecommerce

            In terms of E-commerce title tags. We are a manufacturer of our own clothing products. We are new to the SEO landscape so if this question is an obvious answer, then i apologize for wasting any one times in advance. We Manufacture our own clothing. Each item has a name. The names are American womens names such as amanda or lori or jenniffer etc. When we create the title tag for them should we include the name of the item itself at the beginning or end.  For example should it be Item Name - Keyword - Keyword - Brand Name(aka manufacturer) or Keyword - Keyword - Item Name - Brand Name (aka manufacturer) The reason we ask this is because we think it would be a waste to rank for actual American names such as Jennifer and Jessica. All that we have read on Moz suggests that it seems to be better to have pertinent keywords in the beginning of the title as opposed to the end. In terms of our brand name we already rank number 1 for every combination of our brand. So we would like to start picking up traffic for the different product types we sell and there respective synonyms. Not sure if i am making any sense. Sorry in advance, and any help is very very much appreciated.

            Would changing the file name of an image (not the alt attribute) have an effect of on seo / ranking of that image and thus the site?

            Would changing the file name of image, not the alt attribute nor the image itself (so it would be exactly the same but just a name change) have any effect on : a) A sites seo ranking b) the individual images seo ranking (although i guess if b) would be true it would have an effect on a) although potentially small.) This is the sort of change i would be thinking of making : ![Red ford truck](2554.jpg) changed to ![Red ford truck](6842.jpg)

            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?

            Lowercase VS. Uppercase Canonical tags?

            Hi MOZ, I was hoping that someone could help shed some light on an issue I'm having with URL structure and the canonical tag. The company I work for is a distributor of electrical products and our E-commerce site is structured so that our URL's (specifically, our product detail page URL's) include a portion (the part #) that is all uppercase (e.g: buy/OEL-Worldwide-Industries/AFW-PG-10-10). The issue is that we have just recently included a canonical tag in all of our product detail pages and the programmer that worked on this project has every canonical tag in lowercase instead of uppercase.  Now, in GWT, I'm seeing over 20,000-25,000 "duplicate title tags" or "duplicate descriptions". Is this an issue?  Could this issue be resolved by simply changing the canonical tag to reflect the uppercase URL's?  I'm not too well versed in canonical tags and would love a little insight. Thanks!

            How to See Image Metadata?

            We sell 1000s of audiobooks and get our cover images and descriptions from the publisher’s sites. When I download a cover image such as this one (http://www.audiobooksonline.com/media/Alex-Cross-Run-James-Patterson.jpg)
            I always rename and re-size it before installing at our Web store. Would this process result in any publisher’s metadata in the image we use at our Web store and/or anything else Google would not like?
            Is there an online utility that would allow me to see metadata in our images?

            When using ALT tags - are spaces, hyphens or underscores preferred by Google when using multiple words?

            when plugging ALT tags into images, does Google prefer spaces, hyphens, or underscores?  I know with filenames, hyphens or underscores are preferred and spaces are replaced with %20. Thoughts? Thanks!
