      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 ;-)).

            Htaccess - Redirecting TAG or Category pages

            Hello Fellow Moz's, We have an issue redirecting some /TAG and /Category pages to inner pages. As an example we use: RedirectMatch 301 /category/Sample-Category(.*) https://OurDomain.com.au/New-Page//$1 That works well. The issue is we have other categories and tags that are named similar to /Sample-Category As an example, if we try to redirect /Sample-Category-1 to /New-Page-1 - it will not work, and redirects to /New-Page I assume this is because /Sample-Category is already being redirected, so anything after /Sample-Category like -1 or -2 or -3 etc, will not be recognized. Anyone know of a workaround?

            How to add Canonical Tags on Opencart Products

            Does anyone know how to add canonical tags to product pages in Opencart? Is this possible to do in htaccess? If so, how specifically should it be written in? Please do not post any links to other pages which reference generic canonical information as I've read them all and none help. I'm looking for an Opencart specific answer, or a way to do it in htaccess.

            Putting Dates In Title Tag

            Hi, I have a site were I write previews for sports match ups.  I notice when I don't put the date in the title I rank much better for specific keywords.  I also noticed that most people don't really put in the date when they do the search anyways, especially since google does a good job of showing the most recent pages anyways. The only reason I continue to put the date is because of this whole idea of not having page titles that are duplicate.  So many of our games will be Team A vs Team B Preview, and Im worried that the term "preview" will become so repetitive that google may not like it.  Any tips or ideas on how to approach this issue best? Thanks!

            Lazy Loading of products on an E-Commerce Website - Options Needed

            Hi Moz Fans. We are in the process of re-designing our product pages and we need to improve the page load speed. Our developers have suggested that we load the associated products on the page using Lazy Loading, While I understand this will certainly have a positive impact on the page load speed I am concerned on the SEO impact. We can have upwards of 50 associated products on a page so need a solution. So far I have found the following solution online which uses Lazy Loading and Escaped Fragments - The concern here is from serving an alternate version to search engines. The solution was developed by Google not only for lazy loading, but for indexing AJAX contents in general.
            Here's the official page: Making AJAX Applications Crawlable. The documentation is simple and clear, but in a few words the solution is to use slightly modified URL fragments.
            A fragment is the last part of the URL, prefixed by #. Fragments are not propagated to the server, they are used only on the client side to tell the browser to show something, usually to move to a in-page bookmark.
            If instead of using # as the prefix, you use #!, this instructs Google to ask the server for a special version of your page using an ugly URL. When the server receives this ugly request, it's your responsibility to send back a static version of the page that renders an HTML snapshot (the not indexed image in our case). It seems complicated but it is not, let's use our gallery as an example. Every gallery thumbnail has to have an hyperlink like:  http://www.idea-r.it/...#!blogimage=<image-number></image-number> When the crawler will find this markup will change it to
            http://www.idea-r.it/...?_escaped_fragment_=blogimage=<image-number></image-number> Let's take a look at what you have to answer on the server side to provide a valid HTML snapshot.
            My implementation uses ASP.NET, but any server technology will be good. var fragment = Request.QueryString[``"_escaped_fragment_"``];``if (!String.IsNullOrEmpty(fragment))``{``var escapedParams = fragment.Split(``new``[] { ``'=' });``if (escapedParams.Length == 2)``{``var imageToDisplay = escapedParams[1];``// Render the page with the gallery showing ``// the requested image (statically!)``...``}``} What's rendered is an HTML snapshot, that is a static version of the gallery already positioned on the requested image (server side).
            To make it perfect we have to give the user a chance to bookmark the current gallery image.
            90% comes for free, we have only to parse the fragment on the client side and show the requested image if (window.location.hash)``{``// NOTE: remove initial #``var fragmentParams = window.location.hash.substring(1).split(``'='``);``var imageToDisplay = fragmentParams[1]``// Render the page with the gallery showing the requested image (dynamically!)``...``} The other option would be to look at a recommendation engine to show a small selection of related products instead. This would cut the total number of related products down. The concern with this one is we are removing a massive chunk of content from he existing pages, Some is not the most relevant but its content. Any advice and discussion welcome 🙂

            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

            Creative Commons Images Good for SEO?

            I've been looking at large image packages through iStock, Getty, Fotolia and 123RF, but before spending a bunch of money, I wanted to get some of your feedback on Creative Commons images. Should be worried that something found on Google Images > Search Tools > Usage Rights section can be used without issue or legal threats from the big image companies so long as they are appropriately referenced? AND will using these types of images and linking to the sources have any affect on SEO efforts or make the blog/website look spammy in Google's eyes because we need to link to the source? How are you using Creative Commons images and is there anything I should be aware of in the process of searching, saving, using, referencing, etc? Patrick

            Number of images on Google?

            Hello here, In the past I was able to find out pretty easily how many images from my website are indexed by Google and inside the Google image search index. But as today looks like Google is not giving you any numbers, it just lists the indexed images. I use the advanced image search, by defining my domain name for the "site or domain" field: http://www.google.com/advanced_image_search and then Google returns all the images coming from my website. Is there any way to know the actual number of images indexed? Any ideas are very welcome! Thank you in advance.

            Accidently added a nofollow, noindex tag and then...

            Hey guys, My first post here and ironically highlights a ridiculously stupid mistake! Ok, here's the deal... I started building links to one of my new page on a fairly good, old site (DA = >35). Before starting to build links, I added fresh new content, and while doing that, I accidentally added a "nofollow" and "noindex" tag to the page! Guess what, google DID de-index the page ! So the questions is (and YES, I did change the meta tags): Will google re-index the page with some good linking? Will it treat the page as a new, fresh page even though it was present for over a year? I had already started link building to that page, and now technically the links are pointing to a page that does not exist in the index, so once it does get re-indexed, will Google FLAG it as having too many links? Would I be ranking it as a new page? Will its previous ranking (for very few keywords) will come back? Thanks and Regards, Amod
