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.

How can I stop a tracking link from being indexed while still passing link equity?
I have a marketing campaign landing page and it uses a tracking URL to track clicks. The tracking links look something like this: http://this-is-the-origin-url.com/clkn/http/destination-url.com/ The problem is that Google is indexing these links as pages in the SERPs. Of course when they get indexed and then clicked, they show a 400 error because the /clkn/ link doesn't represent an actual page with content on it. The tracking link is set up to instantly 301 redirect to http://destination-url.com. Right now my dev team has blocked these links from crawlers by adding Disallow: /clkn/ in the robots.txt file, however, this blocks the flow of link equity to the destination page. How can I stop these links from being indexed without blocking the flow of link equity to the destination URL?

Do URLs with canonical tags get indexed by Google?
Hi, we re-branded and launched a new website in February 2016. In June we saw a steep drop in the number of URLs indexed, and there have continued to be smaller dips since. We started an account with Moz and found several thousand high priority crawl errors for duplicate pages and have since fixed those with canonical tags. However, we are still seeing the number of URLs indexed drop. Do URLs with canonical tags get indexed by Google? I can't seem to find a definitive answer on this. A good portion of our URLs have canonical tags because they are just events with different dates, but otherwise the content of the page is the same.

Hreflang tags with link to redirect loop
Hi guys, I'm having a bit of an issue on a client site that I'm hoping someone can help me with. Basically, the client has two domains, one serving users in the Republic of Ireland (http://www.americanholidays.com), showing Euro prices, and the other serving users in Northern Ireland (http://www.americanholidays.com/gb_en/) showing £ prices. The issue I'm having is that the URL for the Northern Ireland page has a 302 on it and goes through another 2/3 301 redirects until it resolves as http://www.americanholidays.com, however it does then show the £ prices. You can see the redirect chain here: http://tools.seobook.com/server-header-checker/?page=single&url=http%3A%2F%2Fwww.americanholidays.com%2Fgb_en%2F&useragent=1&typeProtocol=11 The homepage is using the Hreflang tag, and pointing search engines to serve the http://www.americanholidays.com/gb_en/ page to users using EN-GB as their language. The page is also using a self-referencing canonical, which I believe may negate the whole Hreflang tag anyway? My main question is - is the fact that the Hreflang for the gb_en page is pointing to a chain of redirects negatively affecting it? (I understand too many redirects are never good). Also, is the canonical negating the Hreflang? Any help/info would be great as I just can't get my head around it! Thanks guys Daniel

Numbers in URL
Hey guys! Need your many awesome brains. 🙂 This may be a very basic question but am hoping you can help me out with some insights beyond "because Google says it's better". 🙂 I only recently started working with SEO, and I work for a SaaS website builder company that has millions of open/active user sites, and all our user sites URLs, instead of www.mydomainname.com/gallery or myusername.simplesite.com/about, we use numbers, so www.mysite.com/453112 or myusername.simplesite.com/426521 The Sales manager has asked me to figure out if it will pay off for us in terms of traffic (other benefits?) to change it from the number system to the "proper" and right way of setting up these URLs. He's looking for rather concrete answers, as he usually sits with paid search and is therefore used to the mindset of "if we do x it will yield us y in z months". I'm finding it quite difficult to find case studies/other concrete examples beyond the generic, vague implication that it will simply be "better" (when for example looking at SEO checklists and search engine guidelines). Will it make a difference? How so? I have to convince our developers of the importance and priority of this adjustment, or it will just drown in the many projects they already have. So truly, any insights would be so very welcome. Thank you!

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?

I need help with a PHP canonical URL tags
I found a little difficult for me to do a canonical tag in my PHP. On-Page Report Card We check to make sure that IF you use canonical URL tags, it points to the right page. If the canonical tag points to a different URL, engines will not count this page as the reference resource and thus, it won't have an opportunity to rank. If you've not made this page the rel=canonical target, change the reference to this URL. NOTE: For pages not employing canonical URL tags, this factor does not apply. I don't know how to tidy my PHP Any suggestion.

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?
