Is there a reason to set a crawl-delay in the robots.txt?
-
I've recently encountered a site that has set a crawl-delay command set in their robots.txt file. I've never seen a need for this to be set since you can set that in Google Webmaster Tools for Googlebot. They have this command set for all crawlers, which seems odd to me. What are some reasons that someone would want to set it like that? I can't find any good information on it when researching.

Google does not support the crawl delay command directly, but you can lower your crawl priority inside Google Webmaster Central.
So you are right using it the way you are. If you have it in the robots.txt, it does not really do anything and it will show in the webmaster console as well that GWT does not support it.

Google Webmaster Tools is saying "Sitemap contains urls which are blocked by robots.txt" after Https move...
Hi Everyone, I really don't see anything wrong with our robots.txt file after our https move that just happened, but Google says all URLs are blocked. The only change I know we need to make is changing the sitemap url to https. Anything you all see wrong with this robots.txt file? robots.txt This file is to prevent the crawling and indexing of certain parts of your site by web crawlers and spiders run by sites like Yahoo! and Google. By telling these "robots" where not to go on your site, you save bandwidth and server resources. This file will be ignored unless it is at the root of your host: Used: http://example.com/robots.txt Ignored: http://example.com/site/robots.txt For more information about the robots.txt standard, see: http://www.robotstxt.org/wc/robots.html For syntax checking, see: http://www.sxw.org.uk/computing/robots/check.html Website Sitemap Sitemap: http://www.bestpricenutrition.com/sitemap.xml Crawlers Setup User-agent: * Allowable Index Allow: /*?p=

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.

What does the Google Crawler see when crawling this page?
If you look at this page http://www.rockymountainatvmc.com/t/49/61/185/730/Batteries. You will see we have a vehicle filter on it. Right now you only see a picture of a battery and some bad text that needs to be updated ( We just hired a copywriter!). Our question is when google crawls this site will thy just see this or will they see all the products that appear after you pick a "machine type" "make" "model" and "year" Any help would be great. Right now we think it just sees this main page how we have set things up; however, we know that the crawler is also crawling some ajax. We just want to be sure of things.

Meta-robots Nofollow on logins and admins
In my SEO MOZ reports I am getting over 400 errors as Meta-robots Nofollow. These are all leading to my admin login page which I do not want robots in. Should I put some code on these pages so the robots know this and don't attempt to and I do not get these errors in my reports?

Understanding the actions needed from a Crawl Report
I've just joined SEOMOZ last week and have not even received my first full-crawl yet, but as you know, I do get the re-crawl report. It shows I have 50 301's and 20 rel canonical's. I'm still very confused as to what I'm supposed to fix...And, all the rel canonical's are my sites main pages, so hence I am still equally confused as to what the canonical is doing and how do I properly setup my site. I'm a technical person and can grasp most things fairly quickly, but on this the light bulb is taking a little while longer to fire-up 🙂 If my question wasn't total jibberish and you can help shed some light, I would be forever grateful. Thank you.

Need Help With Robots.txt on Magento eCommerce Site
Hello, I am having difficulty getting my robots.txt file to be configured properly. I am getting error emails from Google products stating they can't view our products because they are being blocked, and this past week, in my SEO dashboard, the URL's receiving search traffic dropped by almost 40%. Is there anyone that can offer assistance on a good template robots.txt file I can use for a Magento eCommerce website? The one I am currently using was found at this site here: e-commercewebdesign.co.uk/blog/magento-seo/magento-robots-txt-seo.php - However, I am getting problems from Google now because of it. I searched and found this thread here: http://www.magentocommerce.com/wiki/multi-store_set_up/multiple_website_setup_with_different_document_roots#the_root_folder_robots.txt_file - But I felt like maybe I should get some additional help on properly configuring a robots for a Magento site. Thanks in advance for any help. Please, let me know if you need more info to provide assistance.
