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."

Google keeps marking different pages as duplicates
My website has many pages like this: mywebsite/company1/valuation mywebsite/company2/valuation mywebsite/company3/valuation mywebsite/company4/valuation ... These pages describe the valuation of each company. These pages were never identical but initially, I included a few generic paragraphs like what is valuation, what is a valuation model, etc... in all the pages so some parts of these pages' content were identical. Google marked many of these pages as duplicated (in Google Search Console) so I modified the content of these pages: I removed those generic paragraphs and added other information that is unique to each company. As a result, these pages are extremely different from each other now and have little similarities. Although it has been more than 1 month since I made the modification, Google still marks the majority of these pages as duplicates, even though Google has already crawled their new modified version. I wonder whether there is anything else I can do in this situation? Thanks

Does a no-indexed parent page impact its child pages?
If I have a page* in WordPress that is set as private and is no-indexed with Yoast, will that negatively affect the visibility of other pages that are set as children of that first page? *The context is that I want to organize some of the pages on a business's WordPress site into silos/directories. For example, if the business was a home remodeling company, it'd be convenient to keep all the pages about bathrooms, kitchens, additions, basements, etc. bundled together under a "services" parent page (/services/kitchens/, /services/bathrooms/, etc.). The thing is that the child pages will all be directly accessible from the menus, so there doesn't need to be anything on the parent /services/ page itself. Another such parent page/directory/category might be used to keep different photo gallery pages together (/galleries/kitchen-photos/, /galleries/bathroom-photos/, etc.). So again, would it be safe for pages like /services/kitchens/ and /galleries/addition-photos/ if the /services/ and /galleries/ pages (but not /galleries/* or anything like that) are no-indexed? Thanks!

Do you need a canonical tag for search and filter pages?
Hi Moz Community, We've been implementing new canonical tags for our category pages but I have a question about pages that are found via search and our filtering options. Would we still need a canonical tag for pages that show up in search + a filter option if it only lists one page of items? Example below. www.uncommongoods.com/search.html/find/?q=dog&exclusive=1 Thanks!

Canonical Tag when using Ajax and PhantomJS
Hello, We have a site that is built using an AJAX application. We include the meta fragment tag in order to get a rendered page from PhantomJS. The URL that is rendered to google from PhantomJS then is www.oursite.com/?escaped_fragment= In the SERP google of course doesnt include the hashtag in the URL. So my question, with this setup, do i still need a canonical tag and if i do, would the canonical tag be the escaped fragment URL or the regular URL? Much Appreciated!

Is it better to use XXX.com or XXX.com/index.html as canonical page
Is it better to use 301 redirects or canonical page? I suspect canonical is easier. The question is, which is the best canonical page, YYY.com or YYY.com/indexhtml? I assume YYY.com, since there will be many other pages such as YYY.com/info.html, YYY.com/services.html, etc.

Do H2 tags carry more weight than h4 tags?
Of course H tags are key signals for relevance in search. Does an h2 tag send a significantly "louder" signal than an h4 tag?

ALT attribute keyword on the same image but different pages
Hi there, As i'm sure you're probably aware, moz advises to use a keyword within the ALT attribute on pages... On a new website I am launching, I have the ability to add an alt keyword to image headers. On multiple pages we have the exact same image but with different keywords associated them inside the alt attribute. The image itself is a collage of different images and so the keywords used can, quite sneakily, match the image. My question is therefore, will using different keywords on the same image on different pages have a negative effect on SEO? Thanks, Stuart

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?
