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.

I'm struggling to understand (and fix) why I'm getting a 404 error. The URL includes this "%5Bnull%20id=43484%5D" but I cannot find that anywhere in the referring URL. Does anyone know why please? Thanks
Can you help with how to fix this 404 error please? It appears that I have a redirect from one page to the other, although the referring page URL works, but it appears to be linking to another URL with this code at the end of the the URL - %5Bnull%20id=43484%5D that I'm struggling to find and fix. Thanks

Changing URLs for SEO
Hi, Currently we have a page, /business, but we have shifted our strategy to optimize for this page for the keyword "enterprise" instead of "business". The page authority of this page is 18 and our domain authority is 35. I've already updated content and title tags to more of an enterprise focus. Would it be wise to move the page to /enterprise and create a 301 redirect from /business to /enterprise? Or is this too risky from an SEO standpoint? Thanks!

URL Structure
I'm going through the process of redesigning our website, and the URL structure was brought up. We currently have our URLs structured as domain.com/keyword. It seems that some people think setting your URLs up to look like: domain.com/directory/keyword makes more sense from a user's perspective, and from a search engine's perspective. With our directories labeled as services, solutions, clients - I see no value in adding directories as it dilutes the keyword and brings the keyword further away from the domain. Are there situations where adding a directory before the page in the URL makes sense? If anyone has data showing the difference between the two that'd be great! Thanks, Brian

Content and url duplication?
One of the campaign tools flags one of my clients sites as having lots of duplicates. This is true in the sense the content is sort of boiler plate but with the different countries wording changed. The is same with the urls but they are different in the sense a couple of words have changed in the url`s. So its not the case of a cms or server issue as this seomoz advises. It doesnt need 301`s! Thing is in the niche, freight, transport operators, shipping, I can see many other sites doing the same thing and those sites have lots of similar pages ranking very well. In fact one site has over 300 keywords ranked on page 1-2, but it is a large site with an 12yo domain, which clearly helps. Of course having every page content unique is important, however, i suppose it is better than copy n paste from other sites. So its unique in that sense. Im hoping to convince the site owner to change the content over time for every country. A long process. My biggest problem for understanding duplication issues is that every tabloid or broadsheet media website would be canned from google as quite often they scrape Reuters or re-publish standard press releases on their sites as newsworthy content. So i have great doubt that there is a penalty for it. You only have to look and you can see media sites duplication everywhere, everyday, but they get ranked. I just think that google dont rank the worst cases of spammy duplication. They still index though I notice. So considering the business niche has very much the same content layout replicated content, which rank well, is this duplicate flag such a great worry? Many businesses sell the same service to many locations and its virtually impossible to re write the services in a dozen or so different ways.

How can I make Google Webmaster Tools see the robots.txt file when I am doing a .htacces redirec?
We are moving a site to a new domain. I have setup an .htaccess file and it is working fine. My problem is that Google Webmaster tools now says it cannot access the robots.txt file on the old site. How can I make it still see the robots.txt file when the .htaccess is doing a full site redirect? .htaccess currently has: Options +FollowSymLinks -MultiViews

Re-write of url
Hi, I would like your input on the following dilemma I am wanting to target the keyword "download xml". at the moment Google indexes us on page 2 and indexes the page www.ourdomain.com/download.aspx I would like to rewrite the url to be /download-xml-editor.aspx The current page is a pr5 and is our most trafficked and externally inked to page. My thoughts are quite mixed on how to do this. approach 1: re-write url of "download.aspx" and setup permanent 301 redirect of download.aspx to download-xml-editor.aspx approach 2: create a new page called download-xml-editor and 301 redirect that to the current stronger page which is download.aspx approach 3: create new page called download-xml-editor with unique content and try and get that page to rank over time, allowing it to build up links and not compromise the current page, then later 301 redirect How would you deal with this and what are your recommendations
