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.

Robots.txt in subfolders and hreflang issues
A client recently rolled out their UK business to the US. They decided to deploy with 2 WordPress installations: UK site - https://www.clientname.com/uk/ - robots.txt location: UK site - https://www.clientname.com/uk/robots.txt
Technical SEO | | lauralou82
US site - https://www.clientname.com/us/ - robots.txt location: UK site - https://www.clientname.com/us/robots.txt We've had various issues with /us/ pages being indexed in Google UK, and /uk/ pages being indexed in Google US. They have the following hreflang tags across all pages: We changed the x-default page to .com 2 weeks ago (we've tried both /uk/ and /us/ previously). Search Console says there are no hreflang tags at all. Additionally, we have a robots.txt file on each site which has a link to the corresponding sitemap files, but when viewing the robots.txt tester on Search Console, each property shows the robots.txt file for https://www.clientname.com only, even though when you actually navigate to this URL (https://www.clientname.com/robots.txt) you’ll get redirected to either https://www.clientname.com/uk/robots.txt or https://www.clientname.com/us/robots.txt depending on your location. Any suggestions how we can remove UK listings from Google US and vice versa?0 -
How do I deindex url parameters
Google indexed a bunch of our URL parameters. I'm worried about duplicate content. I used the URL parameter tool in webmaster to set it so future parameters don't get indexed. What can I do to remove the ones that have already been indexed? For example, Site.com/products and site.com/products?campaign=email have both been indexed as separate pages even though they are the same page. If I use a no index I'm worried about de indexing the product page. What can I do to just deindexed the URL parameter version? Thank you!

Url folder structure
I work for a travel site and we have pages for properties in destinations and am trying to decide how best to organize the URLs basically we have our main domain, resort pages and we'll also have articles about each resort so the URL structure will actually get longer:
Technical SEO | | Vacatia_SEO
A. domain.com/main-keyword/state/city-region/resort-name
_ domain.com/family-condo-for-rent/orlando-florida/liki-tiki-village_ _ domain.com/main-keyword-in-state-city/resort-name-feature _
_ domain.com/family-condo-for-rent/orlando-florida/liki-tiki-village/kid-friend-pool_ B. Another way to structure would be to remove the location and keyword folders and combine. Note that some of the resort names are long and spaces are being replaced dynamically with dashes.
ex. domain.com/main-keyword-in-state-city/resort-name
_ domain.com/family-condo-for-rent-in-orlando-florida/liki-tiki-village_ _ domain.com/main-keyword-in-state-city/resort-name-feature_
_ domain.com/family-condo-for-rent-in-orlando-florida/liki-tiki-village-kid-friend-pool_ Question: is that too many folders or should i combine or break up? What would you do with this? Trying to avoid too many dashes.0 -
Does Bing ignore robots txt files?
Bonjour from "Its a miracle is not raining" Wetherby Uk 🙂 Ok here goes... Why despite a robots text file excluding indexing to site http://lewispr.netconstruct-preview.co.uk/ is the site url being indexed in Bing bit not Google? Does bing ignore robots text files or is there something missing from http://lewispr.netconstruct-preview.co.uk/robots.txt I need to add to stop bing indexing a preview site as illustrated below. http://i216.photobucket.com/albums/cc53/zymurgy_bucket/preview-bing-indexed.jpg Any insights welcome 🙂

Ok to Put a Decimal in a URL?
I'm in the process of creating new product specific URLs for my company. Some of our products have decimals in them for their names as a unit of measurement. For example - .The URL for a 050" widget would be something like: http://www.example.com/product/category/.050-inch-widget My question is - Can I use a decimal in the URL without ticking off the search engines, and/or causing any other unexpected effects?

Can I Disallow Faceted Nav URLs - Robots.txt
I have been disallowing /*? So I know that works without affecting crawling. I am wondering if I can disallow the faceted nav urls. So disallow: /category.html/? /category2.html/? /category3.html/*? To prevent the price faceted url from being cached: /category.html?price=1%2C1000

Should I set up a disallow in the robots.txt for catalog search results?
When the crawl diagnostics came back for my site its showing around 3,000 pages of duplicate content. Almost all of them are of the catalog search results page. I also did a site search on Google and they have most of the results pages in their index too. I think I should just disallow the bots in the /catalogsearch/ sub folder, but I'm not sure if this will have any negative effect?
