      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."

                  http://support.google.com/webmasters/bin/answer.py?hl=en&answer=139394

                  Hope that helps 🙂

                    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 good to redirect million of pages on a single page?

                    My site has 10 lakh approx. genuine urls. But due to some unidentified bugs site has created irrelevant urls 10 million approx.  Since we don’t know the origin of these non-relevant links, we want to redirect or remove all these urls. Please suggest is it good to redirect such a high number urls to home page or to throw 404 for these pages.  Or any other suggestions to solve this issue.

                    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

                    What is the best way to find missing alt tags on my site (site wide - not page by page)?

                    I am looking to find all the missing alt tags on my site at once. I have a FF extension that use to do it page by page, but my site is huge and that will take forever. Thanks!!

                    301 redirects & merging two sites into one

                    We have a client that has two sites that rank well for different searches in their market. The main pages ranking are things like advice articles and news pieces. For various reasons, they just want one site. I believe they need to duplicate the content from the outgoing site and place it on the main site, with a 301 redirect from each old page to each new one. What happens when they eventually want to redirect the entire domain? Would these smaller, internal redirects become obsolete, therefore removing any link value they once had? I am not sure how this works or if there is a best practice way to do this. Thanks Gareth
