Is there a limit to how many URLs you can put in a robots.txt file?
-
We have a site that has way too many urls caused by our crawlable faceted navigation. We are trying to purge 90% of our urls from the indexes. We put no index tags on the url combinations that we do no want indexed anymore, but it is taking google way too long to find the no index tags. Meanwhile we are getting hit with excessive url warnings and have been it by Panda.
Would it help speed the process of purging urls if we added the urls to the robots.txt file? Could this cause any issues for us? Could it have the opposite effect and block the crawler from finding the urls, but not purge them from the index? The list could be in excess of 100MM urls.

Hi Kristen,
I did this recently and it worked. The important part is that you need to block the pages in robots.txt or add a noindex tag to the pages to stop them from being indexed again.
I hope this helps.

Hi all, Google Webmaster Tools has a great tool for this. If you go into WMT and select "Google index", then "remove URLs". You can use regex to remove a large batch of URLs then block them in robots.txt to make sure they stay out of the index.
I hope this helps.

Great thanks for the input. Per Kristen's post I am worried that it could just block the URLs altogether and they will never get purged from the index.

Yes, we have done that and are seeing traction on those urls, but we can't get rid of these old urls as fast as we would like.
Thanks for your input

Thanks Kristen, thats what I was afraid I would do. Other than Fetch is there a way to send Google these URLs in mass? There are over 100 million URLs so Fetch is not scalable. They are picking them up slowly, but at current pace it will take a few months and I would like to find a way to make it purge faster.

You could add them to the robots.txt but it you have to remember that Google will only read the first 500kb (source) - as far as I understand with the number of url's you want to block you'll pass this limit.
As Google bot is able to understand basic regex expressions it's probably better to use regex (you will probably be able to block all these url's with a few lines of code.

Website URL, Robots.txt and Google Search Console (www. vs non www.)
Hi MOZ Community,
Technical SEO | | Badiuzz
I would like to request your kind assistance on domain URLs - www. VS non www. Recently, my team have moved to a new website where a 301 Redirection has been done. Original URL : https://www.example.com.my/ (with www.) New URL : https://example.com.my/ (without www.) Our current robots.txt sitemap : https://www.example.com.my/sitemap.xml (with www.)
Our Google Search Console property : https://www.example.com.my/ (with www.) Question:
1. How/Should I standardize these so that Google crawler can effectively crawl my website?
2. Do I have to change back my website URLs to (with www.) or I just need to update my robots.txt?
3. How can I update my Google Search Console property to reflect accordingly (without www.), because I cannot see the options in the dashboard.
4. Is there any to dos such as Canonicalization needed, or should I wait for Google to automatically detect and change it, especially in GSC property? Really appreciate your kind assistance. Thank you,

Can the Hosting location of image files have a negative effect if on the developers own media server rather than on client site server ?
Hi Can the Hosting location of image files have a negative effect if on the developers own media server as opposed to on the actual websites server ? In the case i'm looking at the image files are hosted on a totally separate server (a media subdomain of the developers site server) from the subject sites dedicated server. Will engines still attribute the properties of files hosted in this manner to the main website (such as file name or should they really be on the subject sites server own media folder ? Cheers Dan

Duplicate content with same URL?
SEOmoz is saying that I have duplicate content on: http://www.XXXX.com/content.asp?ID=ID http://www.XXXX.com/CONTENT.ASP?ID=ID The only difference I see in the URL is that the "content.asp" is capitalized in the second URL. Should I be worried about this or is this an issue with the SEOmoz crawl? Thanks for any help. Mike

How to allow one directory in robots.txt
Hello, is there a way to allow a certain child directory in robots.txt but keep all others blocked? For instance, we've got external links pointing to /user/password/, but we're blocking everything under /user/. And there are too many /user/somethings/ to just block every one BUT /user/password/. I hope that makes sense... Thanks!
