    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

              Dynamic Canonical Tag for Search Results Filtering Page

              canonical indexation search page categorization search results crawl

              Hi everyone, I run a website in the travel industry where most users land on a location page (e.g. domain.com/product/location, before performing a search by selecting dates and times. This then takes them to a pre filtered dynamic search results page with options for their selected location on a separate URL (e.g. /book/results). The /book/results page can only be accessed on our website by performing a search, and URL's with search parameters from this page have never been indexed in the past. We work with some large partners who use our booking engine who have recently started linking to these pre filtered search results pages. This is not being done on a large scale and at present we only have a couple of hundred of these search results pages indexed. I could easily add a noindex or self-referencing canonical tag to the /book/results page to remove them, however it’s been suggested that adding a dynamic canonical tag to our pre filtered results pages pointing to the location page (based on the location information in the query string) could be beneficial for the SEO of our location pages. This makes sense as the partner websites that link to our /book/results page are very high authority and any way that this could be passed to our location pages (which are our most important in terms of rankings) sounds good, however I have a couple of concerns. • Is using a dynamic canonical tag in this way considered spammy / manipulative? • Whilst all the content that appears on the pre filtered /book/results page is present on the static location page where the search initiates and which the canonical tag would point to, it is presented differently and there is a lot more content on the static location page that isn’t present on the /book/results page. Is this likely to see the canonical tag being ignored / link equity not being passed as hoped, and are there greater risks to this that I should be worried about? I can’t find many examples of other sites where this has been implemented but the closest would probably be booking.com. https://www.booking.com/searchresults.it.html?label=gen173nr-1FCAEoggI46AdIM1gEaFCIAQGYARS4ARfIAQzYAQHoAQH4AQuIAgGoAgO4ArajrpcGwAIB0gIkYmUxYjNlZWMtYWQzMi00NWJmLTk5NTItNzY1MzljZTVhOTk02AIG4AIB&sid=d4030ebf4f04bb7ddcb2b04d1bade521&dest_id=-2601889&dest_type=city& Canonical points to https://www.booking.com/city/gb/london.it.html In our scenario however there is a greater difference between the content on both pages (and booking.com have a load of search results pages indexed which is not what we’re looking for) Would be great to get any feedback on this before I rule it out. Thanks!

              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

              Rel=canonical Weebly

              My problem is with my website as it says I have duplicate page titles and contents because of a /index.html. It says the duplicate content is due to the fact that my homepage on my website is www.seacandytackle.com but it is also www.seacandytackle.com/index.html because I use weebly. How can I use the tag to fix this? It won't let me do a 301 redirect because it is a home page. How can I fix this? What code would I have to use and which url? Also it says that I have duplicate page content between http://www.seacandytackle.com/index.html and http://www.seacandytackle.comhttp://www.seacandytackle.com but I don't recall having any page that looks like http://www.seacandytackle.com http://www.seacandytackle.com from weebly. How can I fix this issue as well? Thank you for any help. Step by step implementation would be particularly helpful in using the rel= tags to fix these duplicate issues.

              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?

              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.

              Duplicate title-tags with pagination and canonical

              Some time back we implemented the Google recommendation for pagination (the rel="next/prev"). GWMT now reports 17K pages with duplicate title-tags (we have about 1,1m products on our site and about 50m pages indexed in Google) As an example we have properties listed in various states and the category title would be "Properties for Sale in [state-name]". A paginated search page or browsing a category (see also http://searchengineland.com/implementing-pagination-attributes-correctly-for-google-114970) would then include the following: The title for each page is the same - so to avoid the duplicate title-tags issue, I would think one would have the following options: Ignore what Google says Change the canonical to http://www.site.com/property/state.html (which would then only show the first XX results) Append a page number to the title "Properties for Sale in [state-name] | Page XX" Have all paginated pages use noindex,follow - this would then result in no category page being indexed Would you have the canonical point to the individual paginated page or the base page?

              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.
