Drop Down Menu - Link Juice Depletion
-
Hi,
We have a site with 7 top level sections all of which contain a large number of subsections which may then contain further sub sections.
To try and ensure the best user experience we have a top navigation with the 7 top level sections and when hovered a selection of the key sub sections.
Although I like this format for the user as it makes it easier for them to find the most important sections / sub sections it does lead to a lot of links within every page on the site. In general each top section has a drop down with approx 10 - 15 subsections.
This has therefore lead to SeoMoz's tools issuing its too many internal links warning. Then alongside this I am left wondering if I shouldn’t have to many links to my subsections and whether I would be better off being more selective of when I link to them. For instance I could choose the top 5 sub sections and place a link to them from our homepage and by doing so I would be passing a greater amount of link juice down the line.
So I guess my dilemma is between ensuring the user has as easy a time traversing the site as possible whilst I try to keep a close watch on where, and how, our link juice is distributed.
One solution I am considering is whether no-follow links could be utilised within the drop down menus? This way I could then have the desired user navigation and I would be in greater control of what pages link to which sub sections. Would that even work?
Any advice would be greatly appreciated,
Regards,
Guy

I work for a company that closely mirrors the dropdowns employed by a very large ecommerce site - http://www.surlatable.com/.
Upon analysis of this URL, there are well over 100 links on that page because of the way their dropdowns are designed (over 400 in fact). However, upon close analysis, only 52 of these internal links are followed, and 370 internal links are not followed.
Based on this, I would recommend if you have well in excess of 150 or so links, use nofollow for those less important sub categories like this site has. (I'll have to change the structure of our site now...)

Really appreciate the informative reply. Like you I'm currently the SEO for an ecommerce store which has so many variations and sections that it can be a real headache. We've made good progress flattening the sections and I think from what you said, and a Matt Cutts article I just read on the subject, I'll remove the nofollows, leave Google to it, and take things from there.

This is an interesting question. It also goes with what to do with a mega menu and all its links. I've wondered whether the SE can understand that this is in fact a navigation (you would think they would) for internal links and not penalize your links in the body of the of the page.
According to Google's John Mueller when discussing about HTML5 he stated the following:
"In general, our crawlers are used to not being able to parse all HTML markup - be it from broken HTML, embedded XML content or from the new HTML5 tags. Our general strategy is to wait to see how content is marked up on the web in practice and to adapt to that ..." http://goo.gl/0YehV
You would then believe from that statement that the SE can differentiate navigation menus and drop down list from links in the body? I mean the SE must have crawled zillions of page and that would be a natural conclusion?
That being said I've use two strategies; the first embedding the select options in javascript... something like this
`**<script type="text/javascript"> /* "); document.write("<option values=" ">Select a Property...<\/option>"); document.write("</option><optgroup label="Beach Estates">");</optgroup>** document.write("<option value="\/alii-estate\/">Alii Estate<\/option>");** ......** **......**</option>` **This seems to work well.... but not sure if it is actually crawled** The other strategy that I am more in favor with is to position the drop down list or navigation with a position:absolute; and then place them physically at the bottom of the page ... this seems a better way, but it can affect the site links. I've not done any real testing on this. Burt Gordon

Hi Guy. In terms of no-follow for page rank sculpting purposes, I've read the pros and cons of both and for me I've concluded I'd rather direct the juice where I want it to go rather than to block or prevent it from flowing where I don't want it to flow. No-follow can have unintended results, so I prefer the alternative.
Volume of categories and how to structure them is a challenge for a lot of ecommerce folks (me included). I've recently started flattening my site. While development of useful and intuitive sub-categories helps people find what they want on the 3rd or 4th click, crawl penetration suffers due to the depth. By flattening my site I mean reducing the number of sub-categories that can only be reached by other sub-categories - which is basically moving 3rd or 4th level categories up to the second level or top level (left nav).
A large and top ranking Toy Store I visit often to see how they structure their links has a top nav with categories, a left nav with categories and a sitemap in the footer. Each navigation entry has either different links in it or some different anchor text linking to the same pages. After much reading and apparent consensus among veteran users in this forum, I nixed the sitemap as unnecessary if I use good linking practice throughout the site. One Guru even suggested a sitemap can hurt your rankings if every page is linked to every other page with juice diminishing returns.
In my case, I created a left nav link to additional categories and put categories or sub-categories in them that were either: 1. Removed from the left nav because they were not important enough to be on the left nav 2. Removed from the left nav because on-page analytics suggested they didn't warrant being on the homepage. 3. Were a 3rd or 4th level category that on-page analytics showed there was enough demand to move its link to a second level or top level.
I hope this works for me and could of some help to you. Good luck.

Thank you for the link, I had a read and I've also been making the nofollow adjustments I suggested above.
We have tried to break down the menus into simple, managable chunks. Therefore we are really only linking to important categories. That said we can obviously deem some to be more important to us than others. As such i've employed nofollow tags within the menu on the links which won't generate as much ROI.
Is there any problem with having a nofollow to a certain page within our menu, and then a followed link to that same page within the main page content?

10-15 dropdown links per tab is a lot to fit on the screen, but in my opinion the "too many links on the page" error is a bit overdone. How many total links appear on your pages on average? Unless you're blowing way past the general rule of thumb of 100 links, you're ok.
E.G. if most of your pages have 100-120 or less then don't worry about it. If most of your pages have upwards of 150+ links then definitely reassess how useful each link is to the user, and consider cutting down.

We have 302 redirect links on our forum that point to individual posts. Should we add a rel="nofollow" to these links?
Moz is showing us that we have a HUGE amount of 302 redirects. These are coming from our community forum. Forum URL: https://www.foodbloggerpro.com/community/ Example thread URL: https://www.foodbloggerpro.com/community/viewthread/322/ Example URL that points to a specific reply: https://www.foodbloggerpro.com/community/viewreply/1582/ The above link 302 redirects to this URL: https://www.foodbloggerpro.com/community/viewthread/322/#1582 My two questions would be: Do you think we should we add rel=nofollow to the specific reply URLs? If possible, should we make those redirects 301 vs. 302? Screencast attached. nofollow_302.mp4

Should I no follow all external links?
I have worked with a few different SEO firms lately and a lot of them have recommended on the sites I was working on to "no-follow" all external links on the site. On one hand this traps all the link equity/Pagerank. On the other I would think this practice is frowned upon by Google. What are some opinions on this?

Metrics to determine the quality of a link?
I found this very useful post on SEOMoz http://www.seomoz.org/blog/525600-metrics-how-do-you-measure-measure-a-link, but its a bit dated. Also, it doesn't really help in terms of applying exact metrics to measure the quality of a link. Does anyone have any other suggestions to help automate / determine the quality of a link?
