Is it a problem that Google's index shows paginated page urls, even with canonical tags in place?
-
Since Google shows more pages indexed than makes sense, I used Google's API and some other means to get everything Google has in its index for a site I'm working on.
The results bring up a couple of oddities.
It shows a lot of urls to the same page, but with different tracking code.The url with tracking code always follows a question mark and could look like:
http://www.MozExampleURL.com?tracking-example
http://www.MozExampleURL.com?another-tracking-examle
http://www.MozExampleURL.com?tracking-example-3
etc
So, the only thing that distinguishes one url from the next is a tracking url. On these pages, canonical tags are in place as:
<link rel="canonical<a class="attribute-value">l</a>" href="http://www.MozExampleURL.com" />
So, why does the index have urls that are only different in terms of tracking urls? I would think it would ignore everything, starting with the question mark. The index also shows paginated pages. I would think it should show the one canonical url and leave it at that. Is this a problem about which something should be done? Best... Darcy

Hi Samuel,
Thank you for the detailed answer. A couple of things;
My two "L" typo is just as written here... not on the site. Sorry about that.
On the use of the url parameters indexed, those are used internally, but they're set in GWT as having no effect and to only look at the representative url,.. everything before the question mark.
On your point about rel canonicals, one way we use them is in a category pages which are long lists of other pages. In that case it looks at page one of the long list as the canonical.
With that in mind, along with all the duplicate stuff in the index (paginated page #s, ignored url parameters), what would you suggest I change?
Thanks... Darcy

A couple of things. First, a rel=canonical tag -- like many other things -- is only a suggestion to search engines. Google and others can choose to ignore it, though they rarely do. In your post above, you have "canonicall" spelled with two "l"s -- so it might be as simple as changing that!
Second, just to clarify your teminology: What you are showing is not "tracking code" but "URL paramaters." I'm curious as to why the pages with tracking paramaters are being indexed -- normally, this should not happen at all. How are you using the paramaters? Usually, it should only be used to track traffic from external websites. For example: If I run a Facebook ad campaign, I can add a parameter to the ad's destination URL to track the results of the campaign. Google, however, would not index that special URL as a separate page. I'd review Google's information and recommendations on URL paramaters and perhaps change any settings in Google Webmaster Tools.
Third, the recommended practice for paginated pages is to have a "single page" version of the article and make that canonical for search engines (have all paginated pages point to that single-page one with a rel=canonical tag). This can be done whether you want to show a single-page version for users -- though I'd recommend it because most pagination is a cheap attempt just to get more pageviews for advertising revenue, and it's annoying.
Good luck -- I hope this helps!

Pages excluded from Google's index due to "different canonicalization than user"
Hi MOZ community, A few weeks ago we noticed a complete collapse in traffic on some of our pages (7 out of around 150 blog posts in question). We were able to confirm that those pages disappeared for good from Google's index at the end of January '18, they were still findable via all other major search engines. Using Google's Search Console (previously Webmastertools) we found the unindexed URLs in the list of pages being excluded because "Google chose different canonical than user". Content-wise, the page that Google falsely determines as canonical instead has little to no similarity to the pages it thereby excludes from the index. False canonicalization About our setup: We are a SPA, delivering our pages pre-rendered, each with an (empty) rel=canonical tag in the HTTP header that's then dynamically filled with a self-referential link to the pages own URL via Javascript. This seemed and seems to work fine for 99% of our pages but happens to fail for one of our top performing ones (which is why the hassle 😉 ). What we tried so far: going through every step of this handy guide: https://moz.com/blog/panic-stations-how-to-handle-an-important-page-disappearing-from-google-case-study --> inconclusive (healthy pages, no penalties etc.) manually requesting re-indexation via Search Console --> immediately brought back some pages, others shortly re-appeared in the index then got kicked again for the aforementioned reasons checking other search engines --> pages are only gone from Google, can still be found via Bing, DuckDuckGo and other search engines Questions to you: How does the Googlebot operate with Javascript and does anybody know if their setup has changed in that respect around the end of January? Could you think of any other reason to cause the behavior described above? Eternally thankful for any help! ldWB9

Will Canonical tag on parameter URLs remove those URL's from Index, and preserve link juice?
My website has 43,000 pages indexed by Google. Almost all of these pages are URLs that have parameters in them, creating duplicate content. I have external links pointing to those URLs that have parameters in them. If I add the canonical tag to these parameter URLs, will that remove those pages from the Google index, or do I need to do something more to remove those pages from the index? Ex: www.website.com/boats/show/tuna-fishing/?TID=shkfsvdi_dc%ficol (has link pointing here)

Why Is Google Indexing These Product Pages On Shopify?
How can we communicate to Google the exact product pages we'd like indexed on our site? We're an apparel company that uses Shopify as our ecommerce platform. Website is sportiqe.com. Currently, Google is indexing all types of different pages on our site. **Example of a product page we want indexed: ** Product Page: sportiqe.com/products/PRODUCT-TITLE (Like This) **Examples of product pages being indexed: ** sportiqe.myshopify.com/products/PRODUCT-TITLE sportiqe.com/collections/COLLECTION-NAME/products/PRODUCT-TITLE See attached for an example of how two different "Boston Celtics Grateful Dead" shirts are being indexed. Any suggestions? We've used both Shopify and Google Webmaster tools to set our preferred domain (sportiqe.com). We've also added this snippet of code to our site three months ago thinking that would do the trick... {% if template == 'product' %}{% if collection %} {% endif %}{% endif %} sKwNZOl

What NAP format do I use if the USPS can't even find my client's address?
My client has a site already listed on Google+Local under "5208 N 1st St". He has some other NAPs, e.g., YellowPages, under "5208 N First Street". The USPS finds neither of these, nor any variation that I can possibly think of! Which is better? Do I just take the one that Google has accepted and make all the others like it as best I can? And doesn't it matter that the USPS doesn't even recognize the thing? Or no? Local SEO wizards, thanks in advance for your guidance!

Google replacing subpages in index with home page?
Hi! I run a backlink building company. Recently, we had a customer who had us build targeted backlinks to certain subpages on his site. Then something really bizarre happened...all of a sudden, their subpages that were indexed in Google (the ones we were building links to) disappeared from the index, to be replaced with their home page. They haven't lost their rank, per se--it's just now their home page instead of their subpages. At this point, we are tracking literally thousands of keywords for our link building customers, and we've never run into this issue before. Have you ever run into it? If so, what's the best way to handle it from an SEO company perspective? They have a sitemap.xml and their GWT account reports no crawl errors, so it doesn't seem to be a site issue.
