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?

Dr. Pete,
Do you have any search/sort filters that may be spinning out other copies, beyond just the paginated series? That could be clouding the issue, and these things do get complicated. - How about this is the case? What would you recommend?

Since last week we have chosen to append the page number to the title. Let's see if/how GWMTs status changes.
I would think that the next possible flag would then be on the page-description on paginated pages

I suspect you're ok, then. I'd watch those GWT numbers, but unless you're seeing problems with indexation and ranking, then I'd just consider that a notice. I think you're handling it by the book, at least as well as currently possible with Google's changing and somewhat mixed signals on the subject.

Thanks for that answer. I am already using the pageNo in GWMT (as paginates). None of the searches spin out other copies - what I see in GWMT is only related to browsing through a product category and paginating.

Unfortunately, it can be really tough to tell if Google is honoring the rel=prev/next tags, but I've had gradually better luck with those tags this year. I honestly the GWT issue is a mistake on Google's part, and probably isn't a big deal. They do technically index all of the pages in the series, but the rel=prev/next tags should mitigate any ranking issues that could occur from near-duplicate content. You could add the page # to the title, but I doubt it would have any noticeable impact (other than possibly killing the GWT warning).
I would not canonical to the top page - that's specifically not recommended by Google and has fallen in disfavor over the past couple of years. Technically, you can canonical to a "View All" page, but that has its own issues (practically speaking - such as speed and usability).
Do you have any search/sort filters that may be spinning out other copies, beyond just the paginated series? That could be clouding the issue, and these things do get complicated.
I've had luck in the past with using META NOINDEX, FOLLOW on pages 2+ of pagination, but I've gradually switched to rel=prev/next. Google seems to be getting pickier about NOINDEX, and doesn't always follow the cues consistently. Unfortunately, this is true for all of the cues/tags these days.
Sorry, that's a very long way of saying that I suspect you're ok in this case, as long as the tags are properly implemented. You could tell GWT to ignore the page= parameter in parameter handling, but I'm honestly not sure what impact that has in conjunction with rel=prev/next. It might kill the warning, but the warning's just a warning.

I frequently use the page number in titles. It's not a bad solution where you want them all to get indexed.
Keep an eye on whether it affects CTR from the results though. I also like to ensure that there is always a link to the first page of results. This is useful for the user and also helps push more authority to that first page so that it is more likely to be the one that appears.

Missing Canonical Tag for a PDF document

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.

Product Variations (rel=canonical or 301) & Duplicate Product Descriptions
Hi All, Hoping for a bit of advice here please, I’ve been tasked with building an e-commerce store and all is going well so far. We decided to use Wordpress with Woocommerce as our shop plugin. I’ve been testing the CSV import option for uploading all our products and I’m a little concerned on two fronts: - Product Variations Duplicate content within the product descriptions **Product Variations: - ** We are selling furniture that has multiple variations (see list below) and as a result it creates c.50 product variations all with their own URL’s. Facing = Left, Right Leg style = Round, Straight, Queen Ann Leg colour = Black, White, Brown, Wood Matching cushion = Yes, No So my question is should I 301 re-direct the variation URL’s to the main product URL as from a user perspective they aren't used (we don't have images for each variation that would trigger the URL change, simply drop down options for the user to select the variation options) or should I add the rel canonical tag to each variation pointing back to the main product URL. **Duplicate Content: - ** We will be selling similar products e.g. A chair which comes in different fabrics and finishes, but is basically the same product. Most, if not all of the ‘long’ product descriptions are identical with only the ‘short’ product descriptions being unique. The ‘long’ product descriptions contain all the manufacturing information, leg option/colour information, graphics, dimensions, weight etc etc. I’m concerned that by having 300+ products all with identical ‘long’ descriptions its going to be seen negatively by google and effect the sites SEO. My question is will this be viewed as duplicate content? If so, are there any best practices I should be following for handling this, other than writing completely unique descriptions for each product, which would be extremely difficult given its basically the same products re-hashed. Many thanks in advance for any advice.

Title Tag vs. H1 / H2
OK, Title tag, no problem, it's the SEO juice, appears on SERP, etc. Got it. But I'm reading up on H1 and getting conflicting bits of information ... Only use H1 once? H1 is crucial for SERP Use H1s for subheads Google almost never looks past H2 for relevance So say I've got a blog post with three sections ... do I use H1 three times (or does Google think you're playing them ...) Or do I create a "big" H1 subhead and then use H2s? Or just use all H2s because H1s are scary? 🙂 I frequently use subheads, it would seem weird to me to have one a font size bigger than another, but of course I can adjust that in settings ... Thoughts? Lisa

301 redirect: canonical or non canonical?
Hi, Newbie alert! I need to set up 301 redirects for changed URLs on a database driven site that is to be redeveloped shortly. The current site uses canonical header tags. The new site will also use canonical tags. Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new? Given that the purpose of canonicals is to indicate our preferred URL, then my guess is that's what I should use. However, how can I be sure that Google (for example) has indexed the canonical in every case? Thx in anticipation.

Duplicate Title Tag issue due to Shopify CMS
Hi guys, I'm a novice really when it comes to SEO, yet have taken it in house for the next year or so, firstly because I have had my fingers burnt twice...and secondly, to allow me to recoup some of the loss from my prior campaigns. One thing I have noticed on my site (which uses a Shopify E-commerce CMS), is that Shopify duplicates a url for each my products. An example of this is http://www.vidahomes.co.uk/collections/designer-radiators-heating/products/reina-aliano
Technical SEO | | philscott2006
http://www.vidahomes.co.uk/products/reina-aliano Both products provide exactly the same information, yet appear in different ways subject to how the customer finds them. I contacted Shopify to find a fix to this issue when I noticed a high amount of Duplicate Title Tags in my SEO crawl. Their response was as follows. Using a rel canonical link will help prevent duplicate content issues with search engines. All you need to do is add this line of code: **<link rel="canonical" href="{{ canonical_url }}" />** ** before the tag in the theme.liquid file. It’s that simple :)** The theme liquid file basically generates the outer template for the whole site, and is only compromised when over-ruled. This all seems a little too easy for me, so I am hoping whether someone can elaborate as to whether this will work or not, as I'm not entirely sold on their response. I was always under the impression with canonical tags, that they should be added to the header section of the duplicate page in question, which refers back to the original page. The code I have been told to add above implies that the canonical tag would be added to every page in my site so the Google robot would have a hard time in finding anything at all of relevance Thanks in advance for any assistance with this. Kind Regards Phil Scott Vida Homes0 -

Should there be a canonical tag on my 404 error page?
In my crawl diagnostics, I notice some 4xx client errors. They are appearing for pages that no longer exist, so I'm not sure what the problem is. Shouldn't they just be dealt as 404's? Anyway, on closer inspection I noticed that my 404 error page contains a canonical tag which points to the missing page. Could this be the issue? Is it a good idea to remove the canonical tag from this error page? Thanks.
