Soft 404's from pages blocked by robots.txt -- cause for concern?
-
We're seeing soft 404 errors appear in our google webmaster tools section on pages that are blocked by robots.txt (our search result pages).
Should we be concerned? Is there anything we can do about this?
-
Me too. It was that video that helped to clear things up for me. Then I could see when to use robots.txt vs the noindex meta tag. It has made a big difference in how I manage sites that have large amounts of content that can be sorted in a huge number of ways.
-
Good stuff. I was always under the impression they still crawled them (otherwise, how would you know if the block was removed).
-
Take a look at

to see what I am talking about.
Robots.txt does prevent crawling according to Matt Cutts.
-
Robots.txt prevents indexation, not crawling. The good news is that Googlebot stops crawling 404s.
-
Just a couple of under the hood things to check.
-
Are you sure your robots.txt is setup correctly. Check in GWT to see that Google is reading it.
-
This may be a timing issue. Errors take 30-60 days to drop out (as what I have seen) so did they show soft 404 and then you added them to robots.txt?
If that was the case, this may be a sequence issue. If Google finds a soft 404 (or some other error) then it comes back to spider and is not able to crawl the page due to robots.txt - it does not know what the current status of the page is so it may just leave the last status that it found.
-
I tend to see soft 404 for pages that you have a 301 redirect on where you have a many to one association. In other words, you have a bunch of pages that are 301ing to a single page. You may want to consider changing where some of the 301s redirect so that they going to a specific page vs an index page.
-
If you have a page in robots.txt - you do not want them in Google, here is what I would do. Show a 200 on that page but then put in the meta tags a noindex nofollow.
http://support.google.com/webmasters/bin/answer.py?hl=en&answer=93710
"When we see the noindex meta tag on a page, Google will completely drop the page from our search results, even if other pages link to it"
Let Google spider it so that it can see the 200 code - you get rid of the soft 404 errors. Then toss in the noindex nofollow meta tags to have the page removed from the Google index. It sounds backwards that you have to let Google spider to get it to remove stuff, but it works it you walk through the logic.
Good luck!

SEO Best Practices regarding Robots.txt disallow
I cannot find hard and fast direction about the following issue: It looks like the Robots.txt file on my server has been set up to disallow "account" and "search" pages within my site, so I am receiving warnings from the Google Search console that URLs are being blocked by Robots.txt. (Disallow: /Account/ and Disallow: /?search=). Do you recommend unblocking these URLs? I'm getting a warning that over 18,000 Urls are blocked by robots.txt. ("Sitemap contains urls which are blocked by robots.txt"). Seems that I wouldn't want that many urls blocked. ? Thank you!!

Ranking 1st for a keyword - but when 's' is added to the end we are ranking on the second page
Hi everyone - hope you are well. I can't get my head around why we are ranking 1st for a specific keyword, but then when 's' is added to the end of the keyword - we are ranking on the second page. What could be the cause of this? I thought that Google would class both of the keywords the same, in this case, let's say the keyword was 'button'. We would be ranking 1st for 'button', but 'buttons' we are ranking on the second page. Any ideas? - I appreciate every comment.

Large robots.txt file
We're looking at potentially creating a robots.txt with 1450 lines in it. This will remove 100k+ pages from the crawl that are all old pages (I know, the ideal would be to delete/noindex but not viable unfortunately) Now the issue i'm thinking is that a large robots.txt will either stop the robots.txt from being followed or will slow our crawl rate down. Does anybody have any experience with a robots.txt of that size?

Chinese Sites Linking With Bizarre Keywords Creating 404's
Just ran a link profile, and have noticed for the first time many spammy Chinese sites linking to my site with spammy keywords such as "Buy Nike" or "Get Viagra". Making matters worse, they're linking to pages that are creating 404's. Can anybody explain what's going on, and what I can do?

Robots.txt: Can you put a /* wildcard in the middle of a URL?
We have noticed that Google is indexing the language/country directory versions of directories we have disallowed in our robots.txt. For example: Disallow: /images/ is blocked just fine However, once you add our /en/uk/ directory in front of it, there are dozens of pages indexed. The question is: Can I put a wildcard in the middle of the string, ex. /en/*/images/, or do I need to list out every single country for every language in the robots file. Anyone know of any workarounds?

Blocking Dynamic URLs with Robots.txt
Background: My e-commerce site uses a lot of layered navigation and sorting links. While this is great for users, it ends up in a lot of URL variations of the same page being crawled by Google. For example, a standard category page: www.mysite.com/widgets.html ...which uses a "Price" layered navigation sidebar to filter products based on price also produces the following URLs which link to the same page: http://www.mysite.com/widgets.html?price=1%2C250 http://www.mysite.com/widgets.html?price=2%2C250 http://www.mysite.com/widgets.html?price=3%2C250 As there are literally thousands of these URL variations being indexed, so I'd like to use Robots.txt to disallow these variations. Question: Is this a wise thing to do? Or does Google take into account layered navigation links by default, and I don't need to worry. To implement, I was going to do the following in Robots.txt: User-agent: * Disallow: /*? Disallow: /*= ....which would prevent any dynamic URL with a '?" or '=' from being indexed. Is there a better way to do this, or is this a good solution? Thank you!
