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.

Numbers in URL
Hey guys! Need your many awesome brains. 🙂 This may be a very basic question but am hoping you can help me out with some insights beyond "because Google says it's better". 🙂 I only recently started working with SEO, and I work for a SaaS website builder company that has millions of open/active user sites, and all our user sites URLs, instead of www.mydomainname.com/gallery or myusername.simplesite.com/about, we use numbers, so www.mysite.com/453112 or myusername.simplesite.com/426521 The Sales manager has asked me to figure out if it will pay off for us in terms of traffic (other benefits?) to change it from the number system to the "proper" and right way of setting up these URLs. He's looking for rather concrete answers, as he usually sits with paid search and is therefore used to the mindset of "if we do x it will yield us y in z months". I'm finding it quite difficult to find case studies/other concrete examples beyond the generic, vague implication that it will simply be "better" (when for example looking at SEO checklists and search engine guidelines). Will it make a difference? How so? I have to convince our developers of the importance and priority of this adjustment, or it will just drown in the many projects they already have. So truly, any insights would be so very welcome. Thank you!

Robots.txt and Multiple Sitemaps
Hello, I have a hopefully simple question but I wanted to ask to get a "second opinion" on what to do in this situation. I am working on a clients robots.txt and we have multiple sitemaps. Using yoast I have my sitemap_index.xml and I also have a sitemap-image.xml I do put them in google and bing by hand but wanted to have it added into the robots.txt for insurance. So my question is, when having multiple sitemaps called out on a robots.txt file does it matter if one is before the other? From my reading it looks like you can have multiple sitemaps called out, but I wasn't sure the best practice when writing it up in the file. Example: User-agent: * Disallow: Disallow: /cgi-bin/ Disallow: /wp-admin/ Disallow: /wp-content/plugins/ Sitemap: http://sitename.com/sitemap_index.xml Sitemap: http://sitename.com/sitemap-image.xml Thanks a ton for the feedback, I really appreciate it! :) J

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.

Google insists robots.txt is blocking... but it isn't.
I recently launched a new website. During development, I'd enabled the option in WordPress to prevent search engines from indexing the site. When the site went public (over 24 hours ago), I cleared that option. At that point, I added a specific robots.txt file that only disallowed a couple directories of files. You can view the robots.txt at http://photogeardeals.com/robots.txt Google (via Webmaster tools) is insisting that my robots.txt file contains a "Disallow: /" on line 2 and that it's preventing Google from indexing the site and preventing me from submitting a sitemap. These errors are showing both in the sitemap section of Webmaster tools as well as the Blocked URLs section. Bing's webmaster tools are able to read the site and sitemap just fine. Any idea why Google insists I'm disallowing everything even after telling it to re-fetch?

Robots.txt to disallow /index.php/ path
Hi SEOmoz, I have a problem with my Joomla site (yeah - me too!). I get a large amount of /index.php/ urls despite using a program to handle these issues. The URLs cause indexation errors with google (404). Now, I fixed this issue once before, but the problem persist. So I thought, instead of wasting more time, couldnt I just disallow all paths containing /index.php/ ?. I don't use that extension, but would it cause me any problems from an SEO perspective? How do I disallow all index.php's? Is it a simple: Disallow: /index.php/

Old URL redirect to New URL
Alright I did something dumb a year a go and I'm still paying for it. I changed my hyphenated URL to the non-hyphenated version when I redesigned my website. I say it was dumb because I lost most of my link juice even though I did 301 redirects (via the htaccess file) for almost all of the pages I could find in Google's index. Here's my problem. My new site took a huge hit in traffic (down 60%) when I made the change and even though I've done thousands of redirects my old site is still showing up in the SERPS and send much if not most of my traffic. I don't want to take the old site down in fear it will kill all of my traffic. What should I do? Is there a better method I should explore then 301 redirects? Could the other site be affecting my current rank since it's still there? (FYI...both sites are built on the WP platform). Any help or ideas are greatly appreciated. Thank you! Joe

Converting files from .html to .php or editing .htaccess file
Good day all, I have a bunch of files that are .html and I want to add some .php to them. It seems my 2 options are Convert .html to .php and 301 redirect or add this line of code to my .htaccess file and keep all files that are .html as .html AddType application/x-httpd-php .html My gut is that the 2nd way is better so as not alter any SEO rankings, but wanted to see if anybody had any experience with this line of code in their .htaccess file as definitely don't wan to mess up my entire site 🙂 Thanks for any help! John
