Lowercase VS. Uppercase Canonical tags?
-
Hi MOZ, I was hoping that someone could help shed some light on an issue I'm having with URL structure and the canonical tag.
The company I work for is a distributor of electrical products and our E-commerce site is structured so that our URL's (specifically, our product detail page URL's) include a portion (the part #) that is all uppercase (e.g: buy/OEL-Worldwide-Industries/AFW-PG-10-10).
The issue is that we have just recently included a canonical tag in all of our product detail pages and the programmer that worked on this project has every canonical tag in lowercase instead of uppercase. Now, in GWT, I'm seeing over 20,000-25,000 "duplicate title tags" or "duplicate descriptions".
Is this an issue? Could this issue be resolved by simply changing the canonical tag to reflect the uppercase URL's? I'm not too well versed in canonical tags and would love a little insight.
Thanks!

Thanks for the feedback, Federico! That actually helps a lot and also helps confirm what our programmer has just done (which is changed all the canonical tags to the uppercase URL). I guess now we'll play the waiting game and see if Google reduces the number or duplicates after it's next crawl.
Thanks again!

That should be an easy fix for your programmer. If your internal links point to pages with uppercase letters in them, then have the canonical tags with the uppercase. Almost always, uppercase and lowercase loads the same content as the rewrite rules use the URL to look on the products using a DB that does not distinguish uppercase & lowercase automatically (in MySQL, you can force the query to do so, but that will be actually more difficult to just change the way the programmed made the canonical tags). You should also redirect the pages that are duplicate to the original ones, if they have uppercase letters (the original) then the lowercase version should redirect to the uppercase one (once the canonical tags are properly set).
From MY OWN PERSONAL point of view, I always preferred lowercase URLs... if that's the case there's a little more coding to do, but you will end up with all URLs in lowercase (for some reason almost all CMS automatically convert uppercase letters to lowercase in a page URL, like Wordpress does).
Hope that helps!

Title Tags & Keyword Order
Hi I've read various articles on this - some saying it's still important to have the keyword at the beginning of the title and some saying it's not a big factor anymore? Does anyone have an opinion on this?

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

Canonical tags and product descriptions
I just wanted to check what you guys thought of this strategy for duplicate product descriptions. A sample product is a letter bracelet - a, b, c etc so there are 26 products with identical descriptions. It is going to be extremely difficult to come up with 25 new unique descriptions so with recommendation i'm looking to use the canonical tag. I can't set any to no-index because visitors will look for explicit letters. Because the titles only differ by the letter then a search for either letter bracelet letter a bracelet letter i bracelet will just return results for 'letter bracelet' due to stop words unless the searcher explicitly searches for 'letter "a" bracelet. So I reckon I can make 4 new unique descriptions. I research what are the most popular letters picking 5 from the top (excluding 'a' and 'i'). Equally share the remaining letters between those 5 and with each group set a canonical tag pointing to the primary letter of that group. Does this seem a sensible thing to do?

Should you use a canonical tag on translated content in a multi-language country?
A customer of ours has a website in Belgium. There two main languages in Belgium: Dutch and French.
Intermediate & Advanced SEO | | Zanox
At first there was only a Dutch version with a .be extension. Right now they are implementing the French Belgium version on the URL website.be/fr. All of the content and comments will be translated. Also the URL’s will change from Dutch to French, so you've got two URL’s with the same content but in another language. Question: Should you use a canonical tag on translated content in a multi-language country? I think Google will understand this is just for the usability for a Multilanguage country. What do you guys think???0 -
Frequent FAQs vs duplicate content
It would be helpful for our visitors if we were to include an expandable list of FAQs on most pages. Each section would have its own list of FAQs specific to that section, but all the pages in that section would have the same text. It occurred to me that Google might view this as a duplicate content issue. Each page _does _have a lot of unique text, but underneath we would have lots of of text repeated throughout the site. Should I be concerned? I guess I could always load these by AJAX after page load if might penalize us.

Link + noindex vs canonical--which is better?
In this article http://support.google.com/webmasters/bin/answer.py?hl=en&answer=66359 google mentions if you syndicate content, you should include a link and, ideally noindex, the content, if possible. I'm wondering why google doesn't mention including a canonical instead the link + noindex? Is one better than the other? Any ideas?

Lowercase Company Name - Impact on Rankings?
A company who spells their name in all lower case, uses their name spelled exactly this way in titles & meta descriptions & throughout all of their site's content pages - will it affect rankings (particularly since the company name isn't a recognised word)? For example, let's say the company is called "twintrest" Which <title>would be better:</p> <ul> <li><span style="background-color: initial;">A) </span><span style="background-color: initial;">Twintrest - It's Like a Twitter & Pinterest Cocktail or</span></li> <li><span style="background-color: initial;">B) twintrest - It's Like a Twitter & Pinterest Cocktail</span></li> </ul> <p><span style="background-color: initial;">I am leaning towards "A" because the crawler would recognise "Twintrest" at least as a noun, where as in B it could be misconstrued as a spelling mistake.</span></p> <p>Also, in content it would need to be italicised right? <span style="background-color: initial;">So both these would be ok:</span></p> <ul> <li><span style="background-color: initial;">You should use Twintrest because it rocks. or</span></li> <li><span style="background-color: initial;">You should use </span><em style="background-color: initial;">twintrest </em><span style="background-color: initial;">because it rocks.</span></li> </ul> <p>But not:</p> <ul> <li><span style="background-color: initial;">You should use twintrest because it rocks</span><span style="background-color: initial;">.</span></li> </ul> <p>Is it worth pointing out?</p> <p>I've noticed that jcpenny spell their name in lowercase and use this format in their meta tags, however, they are a well established brand. Is there any evidence to suggest that lowercase may even be advantageous since a lot of searches are carried out in lowercase?</p></title>
