Do you add 404 page into robot file or just add no index tag?
-
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.

No index detected in robots meta tag GSC issue_Help Please
Hi Everyone, We just did a site migration ( URL structure change, site redesign, CMS change). During migration, dev team messed up badly on a few things including SEO. The old site had pages canonicalized and self canonicalized <> New site doesn't have anything (CMS dev error) so we are working retroactively to add canonicalization mechanism The legacy site had URL’s ending with a trailing slash “/” <> new site got redirected to Set of url’s without “/” New site action : All robots are allowed: A new sitemap is submitted to google search console So here is my problem (it been a long 24hr night for me 🙂 ) 1. Now when I look at GSC homepage URL it says that old page is self canonicalized and currently in index (old page with a trailing slash at the end of URL). 2. When I try to perform a live URL test, I get the message "No: 'noindex' detected in 'robots' meta tag" , so indexation cant be done. I have no idea where noindex is coming from. 3. Robots.txt in search console still showing old file ( no noindex there ) I tried to submit new file but old one still coming up. When I click on "See live robots.txt" I get current robots. 4. I see that old page is still canonicalized and attempting to index redirected old page might be confusing google Hope someone can help to get the new page indexed! I really need it 🙂 Please ping me if you need more clarification. Thank you ! Thank you

Is it good or bad to add noindex for empty pages, which will get content dynamically after some days
We have followers, following, friends, etc pages for each user who creates account on our website. so when new user sign up, he may have 0 followers, 0 following and 0 friends, but over period of time he can get those lists go up. we have different pages for followers, following and friends which are allowed for google to index. When user don't have any followers/following/friends, those pages looks empty and we get issue of duplicate content and description too short. so is it better that we add noindex for those pages temporarily and remove noindex tag when there are at least 2 or more people on those pages. What are side effects of adding noindex when there is no data on those page or benefits of it?

If Robots.txt have blocked an Image (Image URL) but the other page which can be indexed has this image, how is the image treated?
Hi MOZers, This probably is a dumb question but I have a case where the robots.tags has an image url blocked but this image is used on a page (lets call it Page A) which can be indexed. If the image on Page A has an Alt tags, then how is this information digested by crawlers? A) would Google totally ignore the image and the ALT tags information? OR B) Google would consider the ALT tags information? I am asking this because all the images on the website are blocked by robots.txt at the moment but I would really like website crawlers to crawl the alt tags information. Chances are that I will ask the webmaster to allow indexing of images too but I would like to understand what's happening currently. Looking forward to all your responses 🙂 Malika

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

How important is the number of indexed pages?
I'm considering making a change to using AJAX filtered navigation on my e-commerce site. If I do this, the user experience will be significantly improved but the number of pages that Google finds on my site will go down significantly (in the 10,000's). It feels to me like our filtered navigation has grown out of control and we spend too much time worrying about the url structure of it - in some ways it's paralyzing us. I'd like to be able to focus on pages that matter (explicit Category and Sub-Category) pages and then just let ajax take care of filtering products below these levels. For customer usability this is smart. From the perspective of manageable code and long term design this also seems very smart -we can't continue to worry so much about filtered navigation. My concern is that losing so many indexed pages will have a large negative effect (however, we will reduce duplicate content and be able provide much better category and sub-category pages). We probably should have thought about this a year ago before Google indexed everything :-). Does anybody have any experience with this or insight on what to do? Thanks, -Jason

Rel=canonical tag on original page?
Afternoon All,
Intermediate & Advanced SEO | | Jellyfish-Agency
We are using Concrete5 as our CMS system, we are due to change but for the moment we have to play with what we have got. Part of the C5 system allows us to attribute our main page into other categories, via a page alaiser add-on. But what it also does is create several url paths and duplicate pages depending on how many times we take the original page and reference it in other categories. We have tried C5 canonical/SEO add-on's but they all seem to fall short. We have tried to address this issue in the most efficient way possible by using the rel=canonical tag. The only issue is the limitations of our cms system. We add the canonical tag to the original page header and this will automatically place this tag on all the duplicate pages and in turn fix the problem of duplicate content. The only problem is the canonical tag is on the original page as well, but it is referencing itself, effectively creating a tagging circle. Does anyone foresee a problem with the canonical tag being on the original page but in turn referencing itself? What we have done is try to simplify our duplicate content issues. We have over 2500 duplicate page issues because of this aliasing add-on and want to automate the canonical tag addition, rather than go to each individual page and manually add this tag, so the original reference page can remain the original. We have implemented this tag on one page at the moment with 9 duplicate pages/url's and are monitoring, but was curious if people had experienced this before or had any thoughts?0 -
Disallowed Pages Still Showing Up in Google Index. What do we do?
We recently disallowed a wide variety of pages for www.udemy.com which we do not want google indexing (e.g., /tags or /lectures). Basically we don't want to spread our link juice around to all these pages that are never going to rank. We want to keep it focused on our core pages which are for our courses. We've added them as disallows in robots.txt, but after 2-3 weeks google is still showing them in it's index. When we lookup "site: udemy.com", for example, Google currently shows ~650,000 pages indexed... when really it should only be showing ~5,000 pages indexed. As another example, if you search for "site:udemy.com/tag", google shows 129,000 results. We've definitely added "/tag" into our robots.txt properly, so this should not be happening... Google showed be showing 0 results. Any ideas re: how we get Google to pay attention and re-index our site properly?
