Do canonical tags pass all of the link juice onto the URL they point to?
-
I have an ecommerce website where the category pages have various sorting and paging options which add a suffix to the URLs. My site is setup so the root category URL, domain.com/category-name, has a canonical tag pointing to domain.com/category-name/page1/price however all links, both interner & external, point to the former (i.e. domain.com/category-name).
I would like to know whether all of the link juice is being passed onto the canonical tag URL? Otherwise should I change the canonical tag to point the other way?
Thanks!

I have to disagree about link juice. In many cases, canonical tags will work much like 301-redirects, and do seem to pass link-juice. I've even seen experiments where people used canonical tags to move an entire domain. I wouldn't recommend it (except in rare cases), but it seemed to work.
I am concerned, though, that you're linking internally to one version, but then using canonical to point to another version. I find that's a bad idea - while it sometimes works, you're sending a mixed signal, and it can cause problems for your SEO efforts. I personally think that a truly canonical URL should be used consistently across the site, including in internal links. Internal links are one of your strongest canonicalization cues.
Unfortunately, it's hard to say if link-juice is being passed, given the mixed signal. I'm afraid there's no great way to measure it, at least on the level of the individual link. I should add that Google also isn't a big fan of setting a canonical to page 1 of search results. They'd generally rather you canonical to a "View All" or use rel=prev/next. Canonical isn't always a good bet for pagination these days.

The canonical tag only really tells the spiders there is similar content on the page that you've used the tag for, I wouldn't say that is passes any real "juice" as you call it.
You should probably restructure your links if you want the full benefit.

Can I use a 301 redirect to pass 'back link' juice to a different domain?
Hi, I have a backlink from a high DA/PA Government Website pointing to www.domainA.com which I own and can setup 301 redirects on if necessary. However my www.domainA.com is not used and has no active website (but has hosting available which can 301 redirect). www.domainA.com is also contextually irrelevant to the backlink. I want the Government Website link to go to www.domainB.com - which is both the relevant site and which also should be benefiting from from the seo juice from the backlink. So far I have had no luck to get the Government Website's administrators to change the URL on the link to point to www.domainB.com. Q1: If i use a 301 redirect on www.domainA.com to redirect to www.domainB.com will most of the backlink's SEO juice still be passed on to www.domainB.com? Q2: If the answer to the above is yes - would there be benefit to taking this a step further and redirect www.domainA.com to a deeper directory on www.domianB.com which is even more relevant?

ie. redirect www.domainA.com to www.domainB.com/categoryB - passing the link juice deeper.0 -
Does Google read dynamic canonical tags?
Does Google recognize rel=canonical tag if loaded dynamically via javascript? Here's what we're using to load: <script> //Inject canonical link into page head if (window.location.href.indexOf("/subdirname1") != -1) { canonicalLink = window.location.href.replace("/kapiolani", ""); } if (window.location.href.indexOf("/subdirname2") != -1) { canonicalLink = window.location.href.replace("/straub", ""); } if (window.location.href.indexOf("/subdirname3") != -1) { canonicalLink = window.location.href.replace("/pali-momi", ""); } if (window.location.href.indexOf("/subdirname4") != -1) { canonicalLink = window.location.href.replace("/wilcox", ""); } if (canonicalLink != window.location.href) { var link = document.createElement('link'); link.rel = 'canonical'; link.href = canonicalLink; document.head.appendChild(link); } script>

Link rel="prev" AND canonical
Hi guys, When you have several tabs on your website with products, you can most likely navigate to page 2, 3, 4 etc...
Technical SEO | | AdenaSEO
You can add the link rel="prev" and link rel="next" tags to make sure that 1 page get's indexed / ranked by Google. am I correct? However this still means that all the pages can get indexed, right? For example a webshop makes use of the link rel="prev" and ="next" tags. In the Google results page though, all the seperate tabs pages are still visible/indexed..
http://www.domain.nl/watches/?tab=1
http://www.domain.nl/watches/?tab=24
http://www.domain.nl/watches/?tab=19
etc..... Can we prevent this, and make sure only the main page get's indexed and ranked, by adding a canonical link on every 'tab page' to the main page --> www.domain.nl/watches/ I hope I explained it well and I'm looking forward to hearing from you. Regards, Tom1 -
Canonical Tag when using Ajax and PhantomJS
Hello, We have a site that is built using an AJAX application. We include the meta fragment tag in order to get a rendered page from PhantomJS. The URL that is rendered to google from PhantomJS then is www.oursite.com/?escaped_fragment= In the SERP google of course doesnt include the hashtag in the URL. So my question, with this setup, do i still need a canonical tag and if i do, would the canonical tag be the escaped fragment URL or the regular URL? Much Appreciated!

Duplicate title-tags with pagination and canonical
Some time back we implemented the Google recommendation for pagination (the rel="next/prev"). GWMT now reports 17K pages with duplicate title-tags (we have about 1,1m products on our site and about 50m pages indexed in Google) As an example we have properties listed in various states and the category title would be "Properties for Sale in [state-name]". A paginated search page or browsing a category (see also http://searchengineland.com/implementing-pagination-attributes-correctly-for-google-114970) would then include the following: The title for each page is the same - so to avoid the duplicate title-tags issue, I would think one would have the following options: Ignore what Google says Change the canonical to http://www.site.com/property/state.html (which would then only show the first XX results) Append a page number to the title "Properties for Sale in [state-name] | Page XX" Have all paginated pages use noindex,follow - this would then result in no category page being indexed Would you have the canonical point to the individual paginated page or the base page?

301 Redirect How Long until the juice passes through to new site
Hi Guys, Following on from a question i asked last week in regard to a 301 http://www.seomoz.org/q/301-redirect-have-no-ranking I was thinking that i had some kind of issue on the site, although i have gone over it with a fine tooth comb i cannot find any issue's and from the amount of reads the thread has had im sure if there was something obvious it would have been pointed out. So i am quite confident the 301 from site A to site B is fine and working as intended, so my question is how long should it take until the juice is passed From site A to Site B as its 9 weeks now and still down 85% on traffic and even text for my home page if copied into the search bar don't bring up my site Bing is fine and did not see any real traffic drops but Google is not giving me back the rankings i had prior Whenever i have done a 301 before the rankings pretty steady and i see no real loss in rankings but this time ... painful all changes in WMT made

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

Do Backlinks to a PDF help with overall authority/link juice for the rest of the domain?
We are working on a website that has some high-quality industry articles available on their website. For each article, there is an abstract with a link to the PDF which is hosted on the domain. We have found in Analytics that a lot of sites link directly to the PDF and not the webpage that has the abstract of the article. Can we get any benefit from a direct PDF link? Or do we need to modify our strategy?
