Do I need canonical link on target page?
-
I've placed in my head tag on duplicate content pages, but do i need to place it on the target page such as http://www.example.com/index.html too?
-
It's not instantaneous, but yes, you should see that number drop over time.
-
After implementing my canonical links, I should see my duplicate page warnings go down in the Errors section of Crawl Diagnostics correct? SEOMOZ parses these correct?
-
Ah yes, I could have been more clear with this. Thanks for the help.

I'm a little confused, because you gave different URLs for the target of your canonical tag and your "target page", so I just want to make sure we're referring to the same thing here. You don't typically need a canonical tag on the canonical version of the URL. Technically, you shouldn't put one there (Bing has specifically said they don't want that, but Google has eased up on it), but practically, I've rarely seen it cause any problems.
In other words, I wouldn't lose sleep over it
Just make sure that the "target page" doesn't actually represent multiple URLs. I've seen some people get confused on that. Typically, having a canonical tag on your home-page can help sweep up variants you might not think about, so I think it can make sense to have one, even on the target. In most cases, though, it's not necessary.
-
Yes you should if you are not using 301 redirection for "non www" with "www" domain.

Nope, not as far as I know. Just add the tag in the head of the non-canonical URLs:
This is from Google's Webmaster Tools Support section:
If you want http://www.example.com/dresses/greendress.html to
be the canonical URL for your listing, you can indicate this to search
engines by adding a element with the attribute
rel="canonical"_ to the section of the non-canonical pages. To do this, create a_
link as follows:
_```
href="http://www.example.com/dresses/greendress.html">_Add this extra information to the section of non-canonical URLs._http://example.com/dresses/greendress.html?gclid=ABCDh
_This tells Google that these URLs all refer to the canonical page at **http://www.example.com/dresses/greendress.html**. _ _**Note**: We recommend __using a link with the attribute `rel="canonical"` to_ _indicate your preferred __URL, but we can't guarantee to follow that preference_ _in all cases._ _[More information about rel="canonical".](http://support.google.com/webmasters/bin/answer.py?answer=139394)_ Hope this helps. Thanks, Anthony_

Combine poorly ranking pages into a single page?
I'm doing on-page optimizations for an apartment management company, and they have about seven apartments listed on their site. Rather than include everything on the same page - /apartments/apartment-name/ - they have the following setup: /apartments/apartment-name/contact /apartments/apartment-name/features /apartments/apartment-name/availability /apartments/apartment-name/gallery /apartments/apartment-name/neighborhood With very few exceptions, none of these pages appear to rank for anything, and those that do either rank very poorly for seemingly random keywords or for keywords like the apartment complex name (alongside the main landing page for the complex). I'm of the mind to recommend combining the pages into a single one that contains all the info, eliminates the chances for duplicate content (all of the neighborhood pages contain the same content verbatim), and prevents keyword cannibalization. Thoughts? Thanks.

Which is better? One dynamically optimised page, or lots of optimised pages?
For the purpose of simplicity, we have 5 main categories in the site - let's call them A, B, C, D, E. Each of these categories have sub-category pages e.g. A1, A2, A3. The main area of the site consists of these category and sub-category pages. But as each product comes in different woods, it's useful for customers to see all the product that come in a particular wood, e.g. walnut. So many years ago we created 'woods' pages. These pages replicate the categories & sub-categories but only show what is available in that particular wood. And of course - they're optimised much better for that wood. All well and good, until recently, these specialist page seem to have dropped through the floor in Google. Could be temporary, I don't know, and it's only a fortnight - but I'm worried. Now, because the site is dynamic, we could do things differently. We could still have landing pages for each wood, but of spinning off to their own optimised specific wood sub-category page, they could instead link to the primary sub-category page with a ?search filter in the URL. This way, the customer is still getting to see what they want. Which is better? One page per sub-category? Dynamically filtered by search. Or lots of specific sub-category pages? I guess at the heart of this question is? Does having lots of specific sub-category pages lead to a large overlap of duplicate content, and is it better keeping that authority juice on a single page? Even if the URL changes (with a query in the URL) to enable whatever filtering we need to do.

Rel="canonical" link should they be to or from an "SEO friendly" url
Thanks for taking the time to review this. So for our example, lets use the following SEO friendly link: http://hiu.calibermediagroup.com/undergraduate-on-campus/academics/colleges/pacific-christian-college-of-ministry-and-biblical-studies/BA-biblical-studies We'll call this link the SEO VERSION The title of the college is" Pacific Christian College of Minstry and Biblical Studies" The title of the program is "BA Biblical Studies" The QUERY version of the link to this page would be something like: http://hiu.calibermediagroup.com/undergraduate-on-campus/academics/colleges/index.php?collegeid=22&programid=34 Keep in mind that the meta title, description, and keyword tags for the page are all administerable The SEO VERSION is automatically created from the title of the college, and the title of the program. Each one of these titles can be overidden with a URL slug individually. For instance, the admin could make the link: http://hiu.calibermediagroup.com/undergraduate-on-campus/academics/colleges/pacific-christian-college-of-ministry/biblical-studies by changing the slug for the college to "pacific-christian-college-of-ministry" and the slug for the program to "biblical-studies". Let's call this version the SLUG VERSION So now we have multiple ways to get to the same content. The question on the table is what is best practice for the rel="canonical" link to keep from getting dinged for duplicate content. Let's say that our SEO VERSION is the canonical link for 1 year. Then the choice was made to optimize the links thru the slugs creating the SLUG VERSION. My assumption is that we would keep the SEO VERSION as the canonical link. But then let's say 6 months later that the title of the program is changed in the admin. Now the SEO VERSION has changed and so has the canonical link. Do we lose the link juice garnered over the last 18 months? It would seem to me, that if we use the QUERY version as the canonical link, then any optimizations or changes affect everything except the canonical link, thus keeping the previous link juice earned. But is having an ugly URL as the canonical link detrimental to SEO? Please advise.

Too many links on a page?
On my blog posts, I have links to all the categories and months, dating back 5-6 years. This make the number of links on each blog page well over 100, which I understand might decrease the value of each page. Is there a problem with having more than 100 links on a page?

Too many on page links on ecommerce site
I have an online store with 10 catagories, many of those have subcategories. I have a tree style navigation menu on the page. This helps people quickly find what they need. However, I end up with about 125 links on the page that way. Does google really penalize me for this? Is there anyway around this? Advice much appreciated!
