      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 ;-)).

            Does Google ignore content styled with 'display:none'?

            Do you know if an H1 within a div that has a 'display: none' style applied will still be crawled and evaluated by Google? We have that situation on this page on line 136: view-source:https://www.junk-king.com/services/items-we-take/foreclosure-cleanouts Of course we also have an H1 up at the top of the page and are concerned that the second one will cause interference with our SEO efforts. I've seen conflicting and inconclusive information on line - not sure. Thanks for any help.

            Too many Tags and Categories what should I do to clean this up?

            Hello, Everyone! I am trying to do a clean up for one of my client sites. I'm noticing that the Categories and tags are way out of hand. It looks like random tags and categories were just added because they could be added. Are all of these tags and categories contributing to duplicate content? And if so What method should I go about to cleaning this up? The only thing that seems logical to me is rel=canonical. Thank you so much!

            Heading Tags (Specifically H2) being used within images

            Hello, Mozzers I have a question regarding placement of heading tags. I have seen this asked a few times on the forum but some are from a couple years ago so wanted to get a more up to date answer regarding this. We want to add H2 tags across our site but our two options are to wrap images we are using as navigation on the top of the page, these are directly below our pages H1 tag and actually make sense. Example H1 title: Vehicles Images are specific brand logo with H2 being wrapped to pull the img alt: "Ford Vehicles" "Checvy vehicles" etc. The wrap would look something like this: I appreciate your time, Chris

            Pagination loading with using AJAX. Should I change this?

            Hello, while I was checking this site; http://www.disfracessimon.com/disfraces-adultos-16.html I found that the pagination is working this way http://www.disfracessimon.com/disfraces-adultos-16.html#/page-2
            http://www.disfracessimon.com/disfraces-adultos-16.html#/page-3 and content is being loaded using AJAX. So, google is not getting the paginated results. Is this a big issue or there is no problem?
            Should I create a link for See All Products or there is not a big issue? Thank you!

            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?

            Image URLs - best practice

            Hi - I'm assuming image URL best practice follows same principles as non image URLs (not too many files and so on) - I notice alot of web devs putting photos in subdomains, so wonder if I'm missing something (I usually avoid subdomains like the plague)!

            Noindex : Do Follow or No Follow Tags?

            Hello, I have a website with tags (which have the noindex tag) on each article post. I've been told that I should noindex/nofollow these tag pages, because they are getting link juice passed to them, and since they aren't getting indexed, it's wasting link juice to those pages, when the link juice could be passed to a page that is actually getting indexed. What are your thoughts on this? Also, what would be the point to noindex/follow a page, if you are noindexing that page? Isn't it just wasting link juice? What is the proper SEO way to optimize tags.
