What is the best way to hide duplicate, image embedded links from search engines?
-
**Hello!
Hoping to get the community’s advice on a technical SEO challenge we are currently facing. [My apologies in advance for the long-ish post. I tried my best to condense the issue, but it is complicated and I wanted to make sure I also provided enough detail.]
Context: I manage a human anatomy educational website that helps students learn about the various parts of the human body. We have been around for a while now, and recently launched a completely new version of our site using 3D CAD images. While we tried our best to design our new site with SEO best practices in mind, our daily visitors dropped by ~15%, despite drastic improvements we saw in our user interaction metrics, soon after we flipped the switch.
SEOMoz’s Website Crawler helped us uncover that we now may have too many links on our pages and that this could be at least part of the reason behind the lower traffic. i.e. we are not making optimal use of links and are potentially ‘leaking’ link juice now.
Since students learn about human anatomy in different ways, most of our anatomy pages contain two sets of links:
-
Clickable links embedded via JavaScript in our images. This allows users to explore parts of the body by clicking on whatever objects interests them. For example, if you are viewing a page on muscles of the arm and hand and you want to zoom in on the biceps, you can click on the biceps and go to our detailed biceps page.
-
Anatomy Terms lists (to the left of the image) that list all the different parts of the body on the image. This is for users who might not know where on the arms the biceps actually are. But this user could then simply click on the term “Biceps” and get to our biceps page that way.
Since many sections of the body have hundreds of smaller parts, this means many of our pages have 150 links or more each. And to make matters worse, in most cases, the links in the images and in the terms lists go to the exact same page.
My Question: Is there any way we could hide one set of links (preferably the anchor text-less image based links) from search engines, such that only one set of links would be visible? I have read conflicting accounts of different methods from using JavaScript to embedding links into HTML5 tags. And we definitely do not want to do anything that could be considered black hat.
Thanks in advance for your thoughts!

The drop in your site traffic may be due to a number of things, not just links on the page. If you restructured your URLs, changed title tags, etc etc. There can be lots of reasons besides number of links on the page. You now have a new site that Google is trying to sort out and so you may simply have a little drop in the SERPs.
If you have the tools, look and see if your ranking did drop and monitor that. Also use your analytics to see where the drop is coming from.
There are a couple of good posts on SEOMoz that have info on the 100 page link rule

Bad Domain Links - Penguin? - Moz vs. Search Console Stats?
I've been trying to figure out why my site www.stephita.com has lost it's google ranking the past few years. I had originally thought it was due to the Panda updates, but now I'm concerned it might be because of the Penguin update. Hard for me to pinpoint, as I haven't been actively looking at my traffic stats the past years. So here's what I just noticed. On my Google Search Console - Links to your Site, I discovered there are 301 domains, where over 75% seem to be spammy. I didn't actively create those links. I'm using the MOZ - Open site Explorer tool to audit my site, and I noticed there is a smaller set of LINKING DOMAINS, at about 70 right now. Is there a reason, why MOZ wouldn't necessarily find all 300 domains? What's the BEST way to clean this up??? I saw there's a DISAVOW option in the Google Search Console, but it states it's not the best way, as I should be contacting the webmasters of all the domains, which is I assume impossible to get a real person on the other end to REMOVE these link references. HELP! 🙂 What should I do?

How get an image on a third party site rank high on goode images?
Hello, I have sometimes articles written about my product online, is there anything else I can do except make a good file name for it, perhaps I can ask the site owner to modify in the article to make it rank higher? Also on some small websites I can see that images rank very high for the specific search term that is difficult to rank for in images, if I were to contact the site with a sponsored post request, what I should make sure the site adds except filename to that sponsored post... I think there are also some other methods such as reddit to make images rank high on third party page, just need to find out how... thanks a lot

Does Disavowing Links Negate Anchor Text, or Just Negates Link Juice
I'm not so sure that disavowing links also discounts the anchor texts from those links. Because nofollow links absolutely still pass anchor text values. And disavowing links is supposed to be akin to nofollowing the links. I wonder because there's a potential client I'm working on an RFP for and they have tons of spammy directory links all using keyword rich anchor texts and they lost 98% of their traffic in Pengiun 1.0 and haven't recovered. I want to know what I'm getting into. And if I just disavow those links, I'm thinking that it won't help the anchor text ratio issues. Can anyone confirm?

301 Externally Linked, But Non-Producing Pages, To Productive Pages Needing Links?
I'm working on a site that has some non-productive pages without much of an upside potential, but that are linked-to externally. The site also has some productive pages, light in external links, in a somewhat related topic. What do you think of 301ing the non-productive pages with links to the productive pages without links in order to give them more external link love? Would it make much of a difference? Thanks...

Add or not add "nofollow" to duplicate internal links?
Hello everyone. I have searched on these forums for an answer to my concerns, and despite I found many discussions and questions about applying or not applying "nofollow" to internal links, I couldn't find an answer specific to my particular scenarios. Here is my first scenario: I have an e-commerce site selling digital sheet music, and on my category pages our products are shown typically with the following format: PRODUCT TITLE link that takes to product page Short description text "more info" link that takes to the same product page again As you may notice, the "more info" link takes at the very same page of the PRODUCT TITLE link. So, my question is: is there any benefit to "nofollow" the "more info" link to tell SEs to "ignore" that link? Or should I leave the way it is and let the SE figure it out? My biggest concern by leaving the "nofollow" out is that the "more info" generic and repetitive anchor text could dilute or "compete" with the keyword content of the PRODUCT TITLE anchor text.... but maybe that doesn't really matter! Here a typical category page from my site; http://www.virtualsheetmusic.com/downloads/Indici/Guitar.html My second scenario: on our product pages, we have several different links that take to the very same "preview page" of the product we sell. Each link has a different anchor text, and some other links are just images, all taking to the same page. Here are the anchor texts or ALT text of such same links: "Download Free Sample" (text link) "Cover of the [product title]" (ALT image text) "Look inside this title" (ALT image text) "[product title] PDF file" (ALT image text) "This item contains one high quality PDF sheet music file ready to download and print." (ALT image text) "PDF" (text link) "[product title] PDF file" (ALT image text) So, I have 7 links on the same product page taking the user to the same "product preview page" which is, by the way, canonicalized to the "main" product page we are talking about. Here is an example of product page on my site: http://www.virtualsheetmusic.com/score/Moonlight.html My instinct is to tell SEs to take into account just the links with the "[product title] PDF file" anchor text, and then add a "nofollow" to the other links... but may that hurting in some way? Is that irrelevant? Doesn't matter? How should I move? Just ignore this issue and let the SEs figure it out? Any thoughts are very welcome! Thank you in advance.

Best Way to Consolidate Domains?
Hello, My company has four websites in the same vertical and we're planning to integrate them all on our main company site. So instead of www.siteone.com, www.sitetwo.com, www.sitethree.com, etc. It would be www.branddomain.com/site-one, www.branddomain.com/site-two, etc. I have a few questions... Should we redirect the old domains to the new directories or leave the old domains and stop updating them with new content... Then have the old content, links, etc. 301 to the same content on the new site? Should we literally move all of the content to the new directories? Any tips are appreciated. It's probably pretty obvious that I don't have a ton of technical skills... my development team will be doing the heavy lifting. I just want to be sure we do this correctly from an SEO perspective! Thanks for the help, please let me know if I can clarify anything. E

Any idea why I can't add a Panoramio image link to my Google Places page?
Hey guys & gals! Last week, I watched one of the Pro Webinars on here related to Google Places. Since then, I have begun to help one of my friends with his GP page to get my feet wet. One of the tips from the webinar was to geotag images in Panoramio to use for your images on the Places page. However, when I try to do this, I just get an error that says they can't upload it at this time. I tried searching online for answers, but the G support pages that I have found where someone asks the same question, there is no resolution. Can anyone help? PS - I would prefer not to post publicly the business name, URL, etc. So, if that info is needed, I can PM. Thanks a lot!
