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.

Removing a canonical tag from Pagination pages
Hello, Currently on our site we have the rel=prev/next markup for pagination along with a self pointing canonical via the Yoast Plugin. However, on page 2 of our paginated series, (there's only 2 pages currently), the canonical points to page one, rather than page 2. My understanding is that if you use a canonical on paginated pages it should point to a viewall page as opposed to page one. I also believe that you don't need to use both a canonical and the rel=prev/next markup, one or the other will do. As we use the markup I wanted to get rid of the canonical, would this be correct? For those who use the Yoast Plugin have you managed to get that to work? Thanks!

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!

Will Google Recrawl an Indexed URL Which is No Longer Internally Linked?
We accidentally introduced Google to our incomplete site. The end result: thousands of pages indexed which return nothing but a "Sorry, no results" page. I know there are many ways to go about this, but the sheer number of pages makes it frustrating. Ideally, in the interim, I'd love to 404 the offending pages and allow Google to recrawl them, realize they're dead, and begin removing them from the index. Unfortunately, we've removed the initial internal links that lead to this premature indexation from our site. So my question is, will Google revisit these pages based on their own records (as in, this page is indexed, let's go check it out again!), or will they only revisit them by following along a current site structure? We are signed up with WMT if that helps.

Updating inbound links vs. 301 redirecting the page they link to
Hi everyone, I'm preparing myself for a website redesign and finding conflicting information about inbound links and 301 redirects. If I have a URL (we'll say website.com/website) that is linked to by outside sources, should I get those outside sources to update their links when I change the URL to website.com/webpage? Or is it just as effective from a link juice perspective to simply 301 redirect the old page to the new page? Are there any other implications to this choice that I may want to consider? Thanks!

How much domain authority is passed on through a link from a page with low authority?
Hello, Let's say that there is a link to site A from site B. The domain authority of site B is 85, but the link is on a page that has a page authority of only 1. Does much authority get passed along from site B to site A? (Let's assume site A has a domain authority of 35, if that's relevant.) Thank you!

The Mysterious Case of Pagination, Canonical Tags
Hey guys, My head explodes when I think of this problem. So I will leave it to you guys to find a solution... My root domain (xxx.com) runs on WordPress platform. I use Yoast SEO plugin. The next page of root domain -- page/2/ -- has been canonicalized to the same page -- page/2/ points to page/2/ for example. The page/2/ and remaining pages also have this rel tags: I have also added "noindex,follow" to page/2/ and further -- Yoast does this automatically. Note: Yoast plugin also adds canonical to page/2/...page/3/ automatically. Same is the case with category pages and tag pages. Oh, and the author pages too -- they all have self-canonicalization, rel prev & rel next tags, and have been "noindex, followed." Problem: Am I doing this the way it should be done? I asked a Google Webmaster employee on rel next and prev tags, and this is what she said: "We do not recommend noindexing later pages, nor rel="canonical"izing everything to the first page." (My bad, last year I was canonicalizing pages to first page). One of the popular blog, a competitor, uses none of these tags. Yet they rank higher. Others following this format have been hit with every kind of Google algorithm I could think of. I want to leave it to Google to decide what's better, but then again, Yoast SEO plugin rules my blog -- okay, let's say I am a bad coder. Any help, suggestions, and thoughts are highly appreciated. 🙂 Update 1: Paginated pages -- including category pages and tag pages -- have unique snippets; no full-length posts. Thought I'd make that clear.

URL query strings and canonical tag
Hi, I have recently been getting my comparison website redesigned and developed onto wordpress and the site is now 90% complete. Part of the redesign has meant that there are now dynamic urls in the format: http://www.mywebsite.com/10-pounds-productss/?display=cost&value=10 I have other pages similar to this but with different content for the different price ranges and these are linked to from the menus: http://www.mywebsite.com/20-pounds-products/?display=cost&value=20 Now my questions are: 1. I am using Joost's All-in-one SEO plugin and this adds a canonical tag to the page that is pointing to http://www.mywebsite.com/10-pounds-products/ which is the permalink. Is this OK as it is or should i change this to http://www.mywebsite.com/10-pounds-products/?display=cost&value=10 2. Which URL will get indexed, what gets shown as the display URL in the SERPs and what page will users land on? I'm a bit confused so apologies if these seem like silly questions. Thanks

Syndication: Link back vs. Rel Canonical
For content syndication, let's say I have the choice of (1) a link back or (2) a cross domain rel canonical to the original page, which one would you choose and why? (I'm trying to pick the best option to save dev time!) I'm also curious to know what would be the difference in SERPs between the link back & the canonical solution for the original publisher and for sydication partners? (I would prefer not having the syndication partners disappeared entirely from SERPs, I just want to make sure I'm first!) A side question: What's the difference in real life between the Google source attribution tag & the cross domain rel canonical tag? Thanks! PS: Don't know if it helps but note that we can syndicate 1 article to multiple syndication partners (It would't be impossible to see 1 article syndicated to 50 partners)
