Appropriate use of rel canonical
-
Hey Guys,I'm a bit stuck. My on-page grade indicated the following two issues and I need to find how how to fix both issues.If you have a solution, could you please let me know how to address these issues? It's all a bit intimidating at the moment!!Thank you so much..****************************************************************************************************************************************Appropriate Use of Rel Canonical
If the canonical tag is pointing to a different URL, engines will not count this page as the reference resource and thus, it won't have an opportunity to rank. Make sure you're targeting the right page (if this isn't it, you can reset the target above) and then change the canonical tag to reference that URL.
Recommendation: 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.
No More Than One Canonical URL Tag
The canonical URL tag is meant to be employed only a single time on an individual URL (much like the title element or meta description). To ensure the search engines properly parse the canonical source, employ only a single version of this tag.
Recommendation: Remove all but a single canonical URL tag

Yeah, I'd really tackle this error first, as the other one could be a false alarm. It sounds like you've got multiple canonical tags on a single page, which Google can't interpret very well (and that might just ignore it or use the wrong one). This often indicates that your CMS is double-placing tags and could signal broader problems.

Since the error message you get is "no more than one canonical URL tag," I am going to go out on a limb and guess that the affected pages have more than one canonical.
You can check this by looking at the source code of the page (which you can do by going into the menu of whatever browser you are using and choosing "page source" or "view source"- it is different in different browsers- look around or use the browser's help feature) and doing a search for rel="<a class="attribute-value">canonical</a>"; this should only appear once. If it appears more than once, remove the ones you don't want.
The canonical should be the URL of the page that you want Google to see as the one to index and return in results. For example, if you are using canonicals because you have tracking codes appended to a URL and that creates the appearance of duplicate content, use the URL without the codes as the canonical one.
Just remember that when you put a canonical URL on a page, you are telling Google to ignore the actual URL of that page and consider it to be the canonical URL instead.

First don't worry we are here for you! Second to me "Rel=" is one of the more misunderstood tools and there are a lot of questions surrounding it's implementation. Here are a few reference points to learn from as well.

- Is there an Advantage of using Rel=”canonical” over 301 redirect? By Matt Cutts
Ok so first how are you currently using the tag? Could you post a screenshot or code example as well as a link to the site? Basically you want to make sure that you are using the Tag as a way to deal with duplicate or similar pages as a way to tell Search Engines what the master version of the page is. In my opinion I would try very hard to avoid dupes and normalize URLs in the first place, meaning the tag is more of a last resort option after you have exhausted other methods. Also there are so many ways a Rel="canonical" can go wrong so seeing how your implementing it would help. So try to let us see how your using it as that would help me give a more targeted solution.

How to use Rich Snippets?
Hi there! I have been hearing a lot about Rich Snippets lately but I don't really know how they work. Are they a very important factor to consider for SEO? I would love to know your thoughts about this. Thanks!

Is Google ignoring my canonicals?
Hi, We have rel=canonical set up on our ecommerce site but Google is still indexing pages that have rel=canonical. For example, http://www.britishbraces.co.uk/braces/novelty.html?colour=7883&p=3&size=599 http://www.britishbraces.co.uk/braces/novelty.html?p=4&size=599 http://www.britishbraces.co.uk/braces/children.html?colour=7886&mode=list These are all indexed but all have rel=canonical implemented. Can anyone explain why this has happened?

How and When Should I use Canonical Url Tags?
Pretty new to the SEO universe. But I have not used any canonical tags, just because there is not definitive source explaining exactly when and why you should use them??? Am I the only one who feels this way?

Re-using content
Hi, I've just sold the domain for a website, so I'm free to re-purpose the content over to another website I own. How can I make sure that Gg doesn't deem it as duplicate? Do I need to let Gg naturally realise that the 'original' website no longer has the content on it? Do I need to hold-off putting the content live again? Should I notify Gg by-way of a de-index request, etc (assuming the domain won't incur any difficulty if I do this)? Thanks in advance.

Changing 301s or using 302s after a relaunch?
We are doing a relaunch and changing nearly every URL. Since the list of redirects is > 5.000 we might have some mistakes we want to change later (i.e. having a 301 to a directory but finding a single page later that fits its purpose better). Can I change the 301 later and will seachengines get that? Can I use 302s for a week or two until I'm sure about my redirects and only than do propper 301s?

<rel canonical="">and Query Strings</rel>
How are you supposed to <rel canonical="" tag="">a page with a query string that has already been indexed? It's not like you're serving that page from a CMS where you have an original page with content to add to the head tag.</rel> For example.... Original Page = http://www.example.com/about/products.php Query String Page = http://www.example.com/about/products.php?src=FrontDoorBox Would adding the <rel canonical="" tag="">to the original page, referencing itself, be the solution so that the next time the original page is crawled, the bot will know that the previously indexed URL with query string should actually be the "original"? That's the only solution I can come up with because there's no way to find the query string rendered page to tag with the canonical.....</rel>

Canonical, 301 or code a workaround?
Hi, Recently I've been trying to tackle an issue on one of my websites. I have a site with around 400 products and 550 pages total. I've been pruning some weaker pages and pages with shallow content, and it's been working really well. My current issue is this: There are about 20 store brands of 6 products on my site that each have their own page. They are identical products just re-branded. Writing content for each of these pages has been difficult, as it's a fairly dry product too. So I have around 120 pages of dry content that is unique but not much different from one another. I want to consolidate but I am not sure how yet. Here is what I am thinking: 1. 301 - I pick one product page as the master, 301 all the other duplicate products to it and then make one page of great content that encompasses all of them. If the 301 juice gets diluted over time I might miss out on some long tails, but I could also gain a lot more from a great content page with 500+ words of really good content as opposed to pages with 150-250 words of just so so content. 2. Canonical - Similar to above. I pick a master page and canonical the other pages to it. Then I could use the great content on all the pages, and still have pages for the specific products. The pages might not show up in search engines but would still be searchable on my site. 3. Coded solution - In my CMS I could always make a workaround where the products still appear on the brands page (just their name with a link to the product page) but all the links direct to a master page. I realize all the solutions are fairly similar, although I am not sure which is ideal. Option 3 is the most expensive/time consuming but it would drop my page total down to around 450 pages. For a while now (dating back to before Panda) I've been trying to get rid of the low quality and outdated product pages so I could focus on the more popular and active pages. Dropping my page total would also help in the SEO efforts as the sheer volume of pages that need links right now is high, and obviously the less pages I have the more time I can spend on each page (content and link building). So what do you think? Should I do any of the 3, a combination of the 3 or something different? Cheers, Vinnie
