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.

301 redirect: canonical or non canonical?
Hi, Newbie alert! I need to set up 301 redirects for changed URLs on a database driven site that is to be redeveloped shortly. The current site uses canonical header tags. The new site will also use canonical tags. Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new? Given that the purpose of canonicals is to indicate our preferred URL, then my guess is that's what I should use. However, how can I be sure that Google (for example) has indexed the canonical in every case? Thx in anticipation.

Why is Google replacing our title tags with URLs in SERP?
Hey guys, We've noticed that Google is replacing a lot of our title tags with URLs in SERP. As far as we know, this has been happening for the last month or so and we can't seem to figure out why. I've attached a screenshot for your reference. What we know: depending on the search query, the title tag may or may not be replaced. this doesn't seem to have any connection to the relevance of the title tag vs the url. results are persistent on desktop and mobile. the length of the title tag doesn't seem to correlate with the replacement. the replacement is happening at mass, to dozens of pages. Any ideas as to why this may be happening? Thanks in advance,

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.

Isnt it better to have headlines in H1 and H2 tags instead of p tags?
I am working with a simple site http://http://lightsigns.com/Uniko_Manufacturing_Limited.html They seek more SEO traffic. However, the two big headlines that read "Wholesale Supply to the Sign and Display Industries" which is on line 241 and 242 of the source code, its in a p tag, i.e. <p <span class="webkit-html-tag">style</p <span>="padding-top: 0pt; " class="paragraph_style_1">Wholesale Supply to the and <p <span class="webkit-html-tag">style</p <span>="padding-bottom: 0pt; " class="paragraph_style_1">Sign and Display Industries Likewise, the product titles are in p tags, also. For example, on the Slide-in Light Box product page, http://lightsigns.com/Slide_In_light_box.html , I have done keyword research and no one is using the words slide in light box.Plus, it is also a p tag, ie. line 43 reads style="padding-bottom: 0pt; padding-top: 0pt; " class="paragraph_style">Slide-in Light Box If I suggest that they make an H2 tag with SEO-optimized keywords such as Display Light Box - Slide-In LIght Box, would this indeed help SEO? In summary, is it correct to say that H1 and H2 tags are stronger signals to the search bots of what the page is about?

Does Yelp pass link juice?
This is probably a profoundly obvious question, but I can't seem to find an explicit answer on the internet, so I'll ask it here: Yelp's links out to local business websites are not nofollow'd, but they go through a javascript-based redirect. My understanding is that javascript redirected links do not pass link juice, so a link from a yelp profile will not directly impact my page authority; however, it looks like yelp does use nofollow judiciously for internal links, so I don't understand why they would allow follow for these "useless" outbound links. Do yelp's javascript-redirected links pass link juice?

Drupal URL Aliases vs 301 Redirects + Do URL Aliases create duplicates?
Hi all! I have just begun work on a Drupal site which heavily uses the URL Aliases feature. I fear that it is creating duplicate links. For example:: we have http://www.URL.com/index.php and http://www.URL.com/ In addition we are about to switch a lot of links and want to keep the search engine benefit. Am I right in thinking URL aliases change the URL, while leaving the old URL live and without creating search engine friendly redirects such as 301s? Thanks for any help! Christian

Trailing Slashes In Url use Canonical Url or 301 Redirect?
I was thinking of using 301 redirects for trailing slahes to no trailing slashes for my urls. EG: www.url.com/page1/ 301 redirect to www.url.com/page1 Already got a redirect for non-www to www already. Just wondering in my case would it be best to continue using htacces for the trailing slash redirect or just go with Canonical URLs?

Should there be a canonical tag on my 404 error page?
In my crawl diagnostics, I notice some 4xx client errors. They are appearing for pages that no longer exist, so I'm not sure what the problem is. Shouldn't they just be dealt as 404's? Anyway, on closer inspection I noticed that my 404 error page contains a canonical tag which points to the missing page. Could this be the issue? Is it a good idea to remove the canonical tag from this error page? Thanks.
