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."

Page titles in browser not matching WP page title
I have an issue with a few page titles not matching the title I have In WordPress. I have 2 pages, blog & creative gallery, that show the homepage title, which is causing duplicate title errors. This has been going on for 5 weeks, so its not an a crawl issue. Any ideas what could cause this? To clarify, I have the page title set in WP, and I checked "Disable PSP title format on this page/post:"...but this page is still showing the homepage title. Is there an additional title setting for a page in WP?

Error: Missing Meta Description Tag on pages I can't find in order to correct

Can you 301 redirect a page to an already existing/old page ?
If you delete a page (say a sub department/category page on an ecommerce store) should you 301 redirect its url to the nearest equivalent page still on the site or just delete and forget about it ? Generally should you try and 301 redirect any old pages your deleting if you can find suitable page with similar content to redirect to. Wont G consider it weird if you say a page has moved permenantly to such and such an address if that page/address existed before ? I presume its fine since say in the scenario of consolidating departments on your store you want to redirect the department page your going to delete to the existing pages/department you are consolidating old departments products into ?

Home Page .index.htm and .com Duplicate Page Content/Title
I have been whittling away at the duplicate content on my clients' sites, thanks to SEOmoz's pro report, and have been getting push back from the account manager at register.com (the site was built here and the owner doesn't want to move it). He says these are the exact same page and he can't access one to redirect to the other. Any suggestions? The SEOmoz report says there is duplicate content on both these urls: Durango Mountain Biking | Durango Mountain Resort - Cascade Village http://www.cascadevillagehotel.com/index.htm Durango Mountain Biking | Durango Mountain Resort - Cascade Village http://www.cascadevillagehotel.com/ Your help is greatly appreciated!

Handling 301s: Multiple pages to a single page (consolidation)
Been scouring the interwebs and haven't found much information on redirecting two serparate pages to a single new page. Here is what it boils down to: Let's say a website has two pages, both with good page authority of products that are becoming fazed out. The products, Widget A and Widget B, are still popular search terms, but they are being combined into ONE product, Widget C. While Widget A and Widget B STILL have plenty to do with Widget C, Widget C is now the new page, the main focus page, and the page you want everyone to see and Google to recognize. Now, do I 301 Widget A and Widget B pages to Widget C, ALTHOUGH Widgets A and B previously had nothing to do with one another? (Remember, we want to try and keep some of that authority the two page have had.) OR do we keep Widget A and Widget B pages "alive", take them off the main navigation, and then put a "disclaimer" on the pages announcing they are now part of Widget C and link to Widget C? OR Should Widgets A and B page be canonicalized to Widget C? Again, keep in mind, widgets A and B previously were not similar, but NOW they are and result in Widget C. (If you are confused, we can provide a REAL work example of what we are talkinga about, but decided to not be specific to our industry for this.) Appreciate any and all thoughts on this.

Robots.txt and canonical tag
In the SEOmoz post - http://www.seomoz.org/blog/robot-access-indexation-restriction-techniques-avoiding-conflicts, it's being said - If you have a robots.txt disallow in place for a page, the canonical tag will never be seen. Does it so happen that if a page is disallowed by robots.txt, spiders DO NOT read the html code ?
