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 & meta noindex--site still shows up on Google Search
I have set up my robots.txt like this: User-agent: *
Technical SEO | | RoxBrock
Disallow: / and I have this meta tag in my on a Wordpress site, set up with SEO Yoast name="robots" content="noindex,follow"/> I did "Fetch as Google" on my Google Search Console My website is still showing up in the search results and it says this: "A description for this result is not available because of this site's robots.txt" This site has not shown up for years and now it is ranking above my site that I want to rank for this keyword. How do I get Google to ignore this site? This seems really weird and I'm confused how a site with little content, that has not been updated for years can rank higher than a site that is constantly updated and improved.1 -
Tools/Software that can crawl all image URLs in a site
Excluding Screaming Frog, what other tools/software to use in order to crawl all image URLs in a site? Because in Screaming Frog, they don't crawl image URLs which are not under the site domain. Example of an image URL outside the client site: http://cdn.shopify.com/images/this-is-just-a-sample.png If the client is: http://www.example.com, Screaming Frog only crawls images under it like, http://www.example.com/images/this-is-just-a-sample.png

Blocked URL parameters can still be crawled and indexed by google?
Hy guys, I have two questions and one might be a dumb question but there it goes. I just want to be sure that I understand: IF I tell webmaster tools to ignore an URL Parameter, will google still index and rank my url? IS it ok if I don't append in the url structure the brand filter?, will I still rank for that brand? Thanks, PS: ok 3 questions :)...

Are robots.txt wildcards still valid? If so, what is the proper syntax for setting this up?
I've got several URL's that I need to disallow in my robots.txt file. For example, I've got several documents that I don't want indexed and filters that are getting flagged as duplicate content. Rather than typing in thousands of URL's I was hoping that wildcards were still valid.

Can too many pages hurt crawling and ranking?
Hi, I work for local yellow pages in Belgium, over the last months we introduced a succesfull technique to boost SEO traffic: we have created over 150k of new pages, all targeting specific keywords and all containing unique content, a site architecture to enable google to find these pages through crawling, xml sitemaps, .... All signs (traffic, indexation of xml sitemaps, rankings, ...) are positive. So far so good. We are able to quickly build more unique pages, and I wonder how google will react to this type of "large scale operation": can it hurt crawling and ranking if google notices big volumes of content (unique content)? Please advice

Robots.txt Sitemap with Relative Path
Hi Everyone, In robots.txt, can the sitemap be indicated with a relative path? I'm trying to roll out a robots file to ~200 websites, and they all have the same relative path for a sitemap but each is hosted on its own domain. Basically I'm trying to avoid needing to create 200 different robots.txt files just to change the domain. If I do need to do that, though, is there an easier way than just trudging through it?

Robots.txt and canonical tag
In the SEOmoz post - http://www.seomoz.org/blog/robot-access-indexation-restriction-techniques-avoiding-conflicts, it's being said - If you have a robots.txt disallow in place for a page, the canonical tag will never be seen. Does it so happen that if a page is disallowed by robots.txt, spiders DO NOT read the html code ?
