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.

Google Indexing Of Pages As HTTPS vs HTTP
We recently updated our site to be mobile optimized. As part of the update, we had also planned on adding SSL security to the site. However, we use an iframe on a lot of our site pages from a third party vendor for real estate listings and that iframe was not SSL friendly and the vendor does not have that solution yet. So, those iframes weren't displaying the content. As a result, we had to shift gears and go back to just being http and not the new https that we were hoping for. However, google seems to have indexed a lot of our pages as https and gives a security error to any visitors. The new site was launched about a week ago and there was code in the htaccess file that was pushing to www and https. I have fixed the htaccess file to no longer have https. My questions is will google "reindex" the site once it recognizes the new htaccess commands in the next couple weeks?

Will disallowing URL's in the robots.txt file stop those URL's being indexed by Google
I found a lot of duplicate title tags showing in Google Webmaster Tools. When I visited the URL's that these duplicates belonged to, I found that they were just images from a gallery that we didn't particularly want Google to index. There is no benefit to the end user in these image pages being indexed in Google. Our developer has told us that these urls are created by a module and are not "real" pages in the CMS. They would like to add the following to our robots.txt file Disallow: /catalog/product/gallery/ QUESTION: If the these pages are already indexed by Google, will this adjustment to the robots.txt file help to remove the pages from the index? We don't want these pages to be found.

Should I be using meta robots tags on thank you pages with little content?
I'm working on a website with hundreds of thank you pages, does it make sense to no follow, no index these pages since there's little content on them? I'm thinking this should save me some crawl budget overall but is there any risk in cutting out the internal links found on the thank you pages? (These are only standard site-wide footer and navigation links.) Thanks!

Ecommerce Site homepage , Is it okay to have Links as H2 Tags as that is relevant to the page ?
Hi All, I have a Rental site and I am bit confused with how best do my H Tags on my homepage I know the H1 is the most important, Then H2 Tags and so on.. and that these tags should really be titles for content. However, I have a few categories (links) on my homepage so I am wondering if I could put these as H2 Tags given that it is relevant to the page . H3 Tags will my News and Guides etc , H4 Tags will the whats on the footer. I am attached a made up screenshot of what I propose for my homepage if someone could please give it a quick look , it would be very much appreciated. I have looked at what some competitors do a lot of them don't seem to have h2's etc but I know it's an important factor for rankings etc. Many thanks Pete dJSFQwI

Links from non-indexed pages
Whilst looking for link opportunities, I have noticed that the website has a few profiles from suppliers or accredited organisations. However, a search form is required to access these pages and when I type cache:"webpage.com" the page is showing up as non-indexed. These are good websites, not spammy directory sites, but is it worth trying to get Google to index the pages? If so, what is the best method to use?

Do search engines crawl links on 404 pages?
I'm currently in the process of redesigning my site's 404 page. I know there's all sorts of best practices from UX standpoint but what about search engines? Since these pages are roadblocks in the crawl process, I was wondering if there's a way to help the search engine continue its crawl. Does putting links to "recent posts" or something along those lines allow the bot to continue on its way or does the crawl stop at that point because the 404 HTTP status code is thrown in the header response?

Is Google indexing Mp3 audio and MIDI music files? Can that cause any duplicate problems?
Hello, I own virtualsheetmusic.com website and we have several thousands of media files (Mp3 and MIDI files) that potentially Google can index. If that's the case, I am wondering if that could cause any "duplicate" issues of some sort since many of such media files have exact file names or same meta information inside. Any thoughts about this issue are very welcome! Thank you in advance to anyone.

Meta NoIndex tag and Robots Disallow
Hi all, I hope you can spend some time to answer my first of a few questions 🙂 We are running a Magento site - layered/faceted navigation nightmare has created thousands of duplicate URLS! Anyway, during my process to tackle the issue, I disallowed in Robots.txt anything in the querystring that was not a p (allowed this for pagination). After checking some pages in Google, I did a site:www.mydomain.com/specificpage.html and a few duplicates came up along with the original with

"There is no information about this page because it is blocked by robots.txt" So I had added in Meta Noindex, follow on all these duplicates also but I guess it wasnt being read because of Robots.txt. So coming to my question. Did robots.txt block access to these pages? If so, were these already in the index and after disallowing it with robots, Googlebot could not read Meta No index? Does Meta Noindex Follow on pages actually help Googlebot decide to remove these pages from index? I thought Robots would stop and prevent indexation? But I've read this:
"Noindex is a funny thing, it actually doesn’t mean “You can’t index this”, it means “You can’t show this in search results”. Robots.txt disallow means “You can’t index this” but it doesn’t mean “You can’t show it in the search results”. I'm a bit confused about how to use these in both preventing duplicate content in the first place and then helping to address dupe content once it's already in the index. Thanks! B0
