      Hi,

      got different opinion on this so i wanted to double check with your comment is.

      We've got /404.html page and I was wondering if you would add this page to robot text so it wouldn't be indexed or would you just add no index tag? What would be the best approach?

      Thanks!

        Hello Rubix,

        Saijo gave you some great advice, but I'm concerned about the fact that you have that page in the first place, and that it produces those URL parameters. It suggests to me that instead of showing a 404 error on the contact-office.aspx page (assuming that pages doesn't exist on that URL) you are redirecting the user who tries to access that URL to the /404.html page (e.g. /404.html?aspxerrorpath=/contact-office.aspx).

        Typically you want the 404 http status code to show on the URL the user is trying to unsuccessfully access. In this case instead of redirecting them to your "404 page URL" you would want to show your customized 404 message (and ensure it returns a 404 status code, use this tool) on www.yourdomain.com/contact-office.aspx.

        I hope this makes sense to you. If not, feel free to ask for clarification.

          404 are OK on your site just make sure you send the proper 404 header response for the 404 page ... Google does NOT index 404 pages ( as long as it sends the 404 header response ) , so you don't need to block them via robots.txt or meta robots.

          Infact GWT warns you about these if they are able to crawl the so called 404 pages that doesn't send a 404 header response , so I think its a good idea NOT to noindex them you will get the warning if something is wrong.

          Google will only index your 404 if you don't do that..they call it soft 404 : https://support.google.com/webmasters/answer/181708?hl=en

            Thanks Martijn,

            I actually want to know what would you do for the 404 page itself. It is something like:

            www.mainurl.com/404.html and for some reason this started to create some other links such as

            www.mainrul.com/404.html?aspxerrorpath=/contact-office.aspx

            Do you think I should add 404 page and subpages to Robot.txt ?

            Thanks!

              Hi Sida,

              I would add a noindex to the page and as you also will return the 404 status code this is enough data for Google to tell not to index the page itself.

              Hope this answers your question.

                How to add Canonical Tags on Opencart Products

                Does anyone know how to add canonical tags to product pages in Opencart? Is this possible to do in htaccess? If so, how specifically should it be written in? Please do not post any links to other pages which reference generic canonical information as I've read them all and none help. I'm looking for an Opencart specific answer, or a way to do it in htaccess.

                How long to re-index a page after being blocked

                Morning all! I am doing some research at the moment and am trying to find out, just roughly, how long you have ever had to wait to have a page re-indexed by Google. For this purpose, say you had blocked a page via meta noindex or disallowed access by robots.txt, and then opened it back up. No right or wrong answers, just after a few numbers 🙂 Cheers, -Andy

                Home page suddenly dropped from index!!

                A client's home page, which has always done very well, has just dropped out of Google's index overnight!
                Webmaster tools does not show any problem. The page doesn't even show up if we Google the company name. The Robot.txt contains: Default Flywheel robots file User-agent: * Disallow: /calendar/action:posterboard/
                Disallow: /events/action~posterboard/ The only unusual thing I'm aware of is some A/B testing of the page done with 'Optimizely' - it redirects visitors to a test page, but it's not a 'real' redirect in that redirect checker tools still see the page as a 200. Also, other pages that are being tested this way are not having the same problem. Other recent activity over the last few weeks/months includes linking to the page from some of our blog posts using the page topic as anchor text. Any thoughts would be appreciated.

                My blog is indexing only the archive and category pages

                Hi there MOZ community.  I am new to the QandA and have a question. I have a blog Its been live for months - but I can not get the posts to rank in the serps.  Oddly only the categories rank.  The posts are crawled it seems - but seen as less important for a reason I don't understand.  Can anyone here help with this? See here for what i mean. I have had several wp sites rank well in the serps - and the posts do much better. Than the categories or archives - super odd. Thanks to all for help!

                Better to 301 or de-index 403 pages

                Google WMT recently found and called out a large number of old unpublished pages as access denied errors. The pages are tagged "noindex, follow."  These old pages are in Google's index. At this point, would it better to 301 all these pages or submit an index removal request or what? Thanks... Darcy

                Adding a Canonical Tag to each page referencing itself?

                Hey Mozers! I've noticed that on www.Zappos.com they have a Canonical tag on each page referencing it self.  I have heard that this is a popular method but I dont see the point in canon tagging a page to its self. Any thoughts?

                Do 404 Pages from Broken Links Still Pass Link Equity?

                Hi everyone, I've searched the Q&A section, and also Google, for about the past hour and couldn't find a clear answer on this. When inbound links point to a page that no longer exists, thus producing a 404 Error Page, is link equity/domain authority lost? We are migrating a large eCommerce website and have hundreds of pages with little to no traffic that have legacy 301 redirects pointing to their URLs. I'm trying to decide how necessary it is to keep these redirects. I'm not concerned about the page authority of the pages with little traffic...I'm concerned about overall domain authority of the site since that certainly plays a role in how the site ranks overall in Google (especially pages with no links pointing to them...perfect example is Amazon...thousands of pages with no external links that rank #1 in Google for their product name). Anyone have a clear answer? Thanks!

                Indexed Pages in Google, How do I find Out?

                Is there a way to get a list of pages that google has indexed? Is there some software that can do this? I do not have access to webmaster tools, so hoping there is another way to do this. Would be great if I could also see if the indexed page is a 404 or other Thanks for your help, sorry if its  basic question 😞
