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

Removing a site from Google index with no index met tags
Hi there! I wanted to remove a duplicated site from the google index. I've read that you can do this by removing the URL from Google Search console and, although I can't find it in Google Search console, Google keeps on showing the site on SERPs. So I wanted to add a "no index" meta tag to the code of the site however I've only found out how to do this for individual pages, can you do the same for a entire site? How can I do it? Thank you for your help in advance! L

Google Search Console "Text too small to read" Errors
What are the guidelines / best practices for clearing these errors? Google has some pretty vague documentation on how to handle this sort of error. User behavior metrics in GA are pretty much in line with desktop usage and don't show anything concerning Any input is appreciated! Thanks m3F3uOI

What punctuation can you use in meta tags? Are there any Google does not like?
So I know you can use dashes and | in meta tags, but can anyone tell me what other punctuation you can use? Also, it'd be great to know what punctuation you can't use. Thanks!

Canonical tag for Home page: with or without / at the end???
Setting up canonical tags for an old site. I really need advice on that darn backslash / at the end of the homepage URL. We have incoming links to the homepage as http://www.mysite.com (without the backslash), and as http://www.mysite.com/ (with the backslash), and as http://www.mysite.com/index.html I know that there should be 301 redirects to just one version, but I need to know more about the canonical tags... Which should the canonical tag be??? (without the backslash) or (with the backslash) Thanks for your help! 🙂

Google not pulling my favicon
Several sites use Google favicon to load favicons instead of loading it from the Website itself. Our favicon is not being pulled from our site correctly, instead it shows the default "world" image. https://plus.google.com/_/favicon?domain=www.example.com Is the address to pull a favicon. When I post on G+ or see other sites that use that service to pull favicons ours isn't displaying, despite it shows up in Chrome, Firefox, IE, etc and we have the correct meta in all pages of our site. Any idea why is this happening? Or how to "ping" Google to update that?

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?

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.

• symbol in title tag
We have a few title tags with a circular dot symbol, which is created by the code "•" Humans see a dot, but googlebot sees • Does this negatively impact our SEO, or is googlebot aware that **• == *** to human eyes
