      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.

                Does having alot of pages with noindex and nofollow tags affect rankings?

                We are an e-commerce marketplace at for alternative fashion and home decor. We have over 1000+ stores on the marketplace.  Early this year, we switched the website from HTTP to HTTPS in March 2018 and also added noindex and nofollow tags to the store about page and store policies (mostly boilerplate content) Our traffic dropped by 45% and we have since not recovered. We have done I am wondering could these tags be affecting our rankings?

                Password Protected Page(s) Indexed

                Hi, I am wondering if my website can get a penalty if some password protected pages are showing up when I search on google: site:www.example.com/sub-group/pass-word-protected-page That shows that my password protected page was indexed either before or after adding the password protection. I've seen people suggest no indexing the page. Is that the best method to take care of this? What if we are planning on pushing the page live later on? All of these pages have no title tag, meta description, image alt text, etc. Should I add them for each page? I am wondering what is the best step, especially if we are planning on pushing the page(s) live. Thanks for any help!

                Substantial difference between Number of Indexed Pages and Sitemap Pages

                Hey there, I am doing a website audit at the moment. I've notices substantial differences in the number of pages indexed (search console), the number of pages in the sitemap and the number I am getting when I crawl the page with screamingfrog (see below). Would those discrepancies concern you? The website and its rankings seems fine otherwise. Total indexed: 2,360 (Search Consule)
                About 2,920 results (Google search "site:example.com")
                Sitemap: 1,229 URLs
                Screemingfrog Spider: 1,352 URLs Cheers,
                Jochen

                Should I set up no index no follow on low quality pages?

                I know it is a good idea for duplicate pages, blog tags, etc. but I remember somewhere that you can help the overall link juice of a website by adding no index no follow or no index follow low quality content pages of your website. Is it still a good idea to do this or was it never a good idea to begin with? Michael

                Pages are Indexed but not Cached by Google. Why?

                Here's an example: I get a 404 error for this: http://webcache.googleusercontent.com/search?q=cache:http://www.qjamba.com/restaurants-coupons/ferguson/mo/all But a search for qjamba restaurant coupons gives a clear result as does this: site:http://www.qjamba.com/restaurants-coupons/ferguson/mo/all What is going on?  How can this page be indexed but not in the Google cache? I should make clear that the page is not showing up with any kind of error in webmaster tools, and Google has been crawling pages just fine.  This particular page was fetched by Google yesterday with no problems, and even crawled again twice today by Google  Yet, no cache.

                How to find all indexed pages in Google?

                Hi, We have an ecommerce site with around 4000 real pages. But our index count is at 47,000 pages in Google Webmaster Tools. How can I get a list of all pages indexed of our domain? trying to locate the duplicate content. Doing a "site:www.mydomain.com" only returns up to 676 results... Any ideas? Thanks, Ben

                Using 2 wildcards in the robots.txt file

                I have a URL string which I don't want to be indexed. it includes the characters _Q1 ni the middle of the string. So in the robots.txt can I use 2 wildcards in the string to take out all of the URLs with that in it?  So something like /_Q1.  Will that pickup and block every  URL with those characters in the string? Also, this is not directly of the root, but in a secondary directory, so .com/.../_Q1.  So do I have to format the robots.txt as //_Q1* as it will be in the second folder or just using /_Q1 will pickup everything no matter what folder it is on? Thanks.
