Two different canonical tags on one page
-
Due to an error, some of my pages now have two canonical tags on them. One is correct and the other goes to a nonsense URL (404 page).
I know I should ideally remove the incorrect ones, but it's a big manual job. Are they doing any harm? Can I just leave them there and let Google figure it out?
The correct ones are higher up in the code. Will this make a difference?
Any help appreciated.

Unfortunately, what Google can do and what they actually do can really vary. If you're mixing signals and doubling up the canonicals, the odds that they'll get it right are pretty low, in my experience. I think it's worth the fix, if these are traffic-generating pages.

You should certainly fix this. You don't want google having to guess what you are trying to tell them. For the most part they will probably get it right, especially in your case with the 404s. But if this is occurring too frequently then they may begin to ignore your canonicals all together. Or worse, you may loose some google trust.
I'd put this on my fix it list.

Thanks Scott. It's only wrong on a few hundred pages and they're all quite deep. If it were wrong on the important pages I'd fix it.
-
You should change it, I'm no canonical expert, but the whole point of having it is to tell google how you want it to show, ex. www.yoursite.com or yoursite.com. If your not going to change it for all of your pages then at least do it for your home page as this is the one that usually gets the most attention.
-
Well that's good news. Think I'll just leave them there then. Thanks!

This is stright from Google Webmasters:
"What happens if rel="canonical" points to a non-existent page? Or if more than one page in a set is specified as the canonical version?
We'll do our best to algorithmically determine an appropriate canonical page, just as we've done in the past."

Does Title Tag location in a page's source code matter?
Currently our meta description is on line 8 for our page - http://www.paintball-online.com/Paintball-Guns-And-Markers-0Y.aspx
Technical SEO | | IstoresincThe title tag, however sits below a bunch of code on line 237
Does the location of the title tag, meta tags, and any structured data have any influence with respect to SEO and search engines? Put another way, could we benefit from moving the title tag up to the top? I "surfed 'n surfed" and could not find any articles about this. I would really appreciate any help on this as our site got decimated organically last May and we are looking for any help with SEO. NIck

Duplicate content on Product pages for different product variations.
I have multiple colors of the same product, but as a result I'm getting duplicate content warnings. I want to keep these all different products with their own pages, so that the color can be easily identified by browsing the category page. Any suggestions?

Error: Missing Meta Description Tag on pages I can't find in order to correct
This seems silly, but I have errors on blog URLs in our WordPress site that I don't know how to access because they are not in our Dashboard. We are using All in One SEO. The errors are for blog archive dates, authors and just simply 'blog'. Here are samples: http://www.fateyes.com/2012/10/

Determining When to Break a Page Into Multiple Pages?
Suppose you have a page on your site that is a couple thousand words long. How would you determine when to split the page into two and are there any SEO advantages to doing this like being more focused on a specific topic. I noticed the Beginner's Guide to SEO is split into several pages, although it would concentrate the link juice if it was all on one page. Suppose you have a lot of comments. Is it better to move comments to a second page at a certain point? Sometimes the comments are not super focused on the topic of the page compared to the main text.

Do I need to add canonical link tags to pages that I promote & track w/ UTM tags?
New to SEOmoz, loving it so far. I promote content on my site a lot and am diligent about using UTM tags to track conversions & attribute data properly. I was reading earlier about the use of link rel=canonical in the case of duplicate page content and can't find a conclusive answer whether or not I need to add the canonical tag to these pages. Do I need the canonical tag in this case? If so, can the canonical tag live in the HEAD section of the original / base page itself as well as any other URLs that call that content (that have UTM tags, etc)? Thank you.

What's the difference between a category page and a content page
Hello, Little confused on this matter. From a website architectural and content stand point, what is the difference between a category page and a content page? So lets say I was going to build a website around tea. My home page would be about tea. My category pages would be: White Tea, Black Tea, Oolong Team and British Tea correct? ( I Would write content for each of these topics on their respective category pages correct?) Then suppose I wrote articles on organic white tea, white tea recipes, how to brew white team etc...( Are these content pages?) Do I think link FROM my category page ( White Tea) to my ( Content pages ie; Organic White Tea, white tea receipes etc) or do I link from my content page to my category page? I hope this makes sense. Thanks, Bill
