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>

I believe it's a limitation of our CMS. I'll see if we can try it in htaccess or PHP. Thanks for the insight.

Thanks for the reply. Doesn't appear Google is recognizing the tag because duplicate pages with it are still showing up in SERPs.

I Wouldn't bet on that working. Why not use the exact same code in .htaccess format, or even PHP? Javascript is a coding language that is parsed after the window starts loading, it's not like PHP where it gets parsed before the load.
Thanks

Hi SoulSurfer,
Read This http://searchengineland.com/tested-googlebot-crawls-javascript-heres-learned-220157
The google bot was able to read rel=nofollow and links were not followed. So I would think the same for rel=canonical as well.
Thanks,
Don

Canonical or hreflang?
I have four English sites for four different countries, UK, Ireland, Australia and New Zealand and I want to share some content between the sites. On the pages that share the content, which is essentially exactly the same on all 4 sites, do I use the hreflang tags like: or do I add a canonical tag to the other three pointing to the "origin", which would be the UK site? I believe it is best practice to use one or the other, but I'm not sure which make sense in this situation.

Does google look at H3 tags?
I've had someone tell me that google doesn't pay attention to H3 tags -- only H1 and H2. I haven't found much online to back this up or discredit it; thought I'd ask the Moz community!

Google is shortening many of my title tags although they are already quite concise
Hi, Title tags of our website are being truncated by Google even though they can be very short (sometimes < 40 characters) and with very few capital letters. We would like to understand why. Example: Principal component analysis (pca) in abcde - OurBrand shows up as: Principal component analysis (pca) in abcd... - OurBrand where abcde is the name of a very common software (5 characters), and OurBrand is a 6 characters long string (could be used in either lower case or upper case). Even when removing the brackets around pca, truncation still occurs... Any clue why?

Do H2 tags carry more weight than h4 tags?
Of course H tags are key signals for relevance in search. Does an h2 tag send a significantly "louder" signal than an h4 tag?

Should I include tags in sitemap?
Hello All, I was wondering if you should include tags and categories in your sitemap. In the past on previous blogs I have always left tags and categories out. The reason for this is a good friend of mine who has been doing SEO for a long time and inhouse always told me that this would result in duplicate content. I thought that it would be a great idea to get some input from the SEOmoz community as this obviously has a big affect on your blog and the number of pages indexed. Any help would be great. Thanks, Luke Hutchinson.

Why are Google search results different if you are log'd into Google or not?
I get different results when I'm log'd into my Google account associated with my website than if I'm not. The same country is occurring. So how can I rely on the google results I'm seeing? For instance my site is page 1 with the improvements I made based on SEOMOZ if I'm log'd in. Yet I'm not on the first 25 pages if I'm not logged in.

Dynamically-generated .PDF files, instead of normal pages, indexed by and ranking in Google
Hi, I come across a tough problem. I am working on an online-store website which contains the functionlaity of viewing products details in .PDF format (by the way, the website is built on Joomla CMS), now when I search my site's name in Google, the SERP simply displays my .PDF files in the first couple positions (shown in normal .PDF files format: [PDF]...)and I cannot find the normal pages there on SERP #1 unless I search the full site domain in Google. I really don't want this! Would you please tell me how to figure the problem out and solve it. I can actually remove the corresponding component (Virtuemart) that are in charge of generating the .PDF files. Now I am trying to redirect all the .PDF pages ranking in Google to a 404 page and remove the functionality, I plan to regenerate a sitemap of my site and submit it to Google, will it be working for me? I really appreciate that if you could help solve this problem. Thanks very much. Sincerely SEOmoz Pro Member
