How to Disallow Tag Pages With Robot.txt
-
Hi i have a site which i'm dealing with that has tag pages for instant -
http://www.domain.com/news/?tag=choice
How can i exclude these tag pages (about 20+ being crawled and indexed by the search engines with robot.txt
Also sometimes they're created dynamically so i want something which automatically excludes tage pages from being crawled and indexed.
Any suggestions?
Cheers,
Mark

What CMS is it Mark ?

Thanks, is there a way to test it out before actually implementing it with the site.
The site is non-wordpress aswell.
Cheers,

I agree. I would suggest adding the noindex on the pages and letting the bots crawl them. Blocking them would prevent future crawl of these pages, but I am guessing you would also want to remove the existing pages.
Therefore add the noindex first, wait a few days and then add the disallow (Although technically if they are noindex, you don't really need the disallow).

Hi Mark
If your using Wordpress then I would recommend SEO Yoast to resolve the tag issue. If not then I suggest you amend the robots.txt file to resolve.
Here is an example:
Disallow: /?tag=
Disallow: /?subcats=
Disallow: /*?features_hash=NOTE:
Be very careful when blocking search engines. Test and test again!

What does Disallow: /french-wines/?* actually do - robots.txt
Hello Mozzers - Just wondering what this robots.txt instruction means: Disallow: /french-wines/?* Does it stop Googlebot crawling and indexing URLs in that "French Wines" folder - specifically the URLs that include a question mark? Would it stop the crawling of deeper folders - e.g. /french-wines/rhone-region/ that include a question mark in their URL? I think this has been done to block URLs containing query strings. Thanks, Luke

What are best page titles for sub-domain pages?
Hi Moz communtity, Let's say a website has multiple sub-domains with hundreds and thousands of pages. Generally we will be mentioning "primary keyword & "brand name" on every page of website. Can we do same on all pages of sub-domains to increase the authority of website for this primary keyword in Google? Or it gonna end up as negative impact if Google consider as duplicate content being mentioned same keyword and brand name on every page even on website and all pages of sub domains? Thanks

Wildcarding Robots.txt for Particular Word in URL
Hey All, So I know that this isn't a standard robots.txt, I'm aware of how to block or wildcard certain folders but I'm wondering whether it's possible to block all URL's with a certain word in it? We have a client that was hacked a year ago and now they want us to help remove some of the pages that were being autogenerated with the word "viagra" in it. I saw this article and tried implementing it https://builtvisible.com/wildcards-in-robots-txt/ and it seems that I've been able to remove some of the URL's (although I can't confirm yet until I do a full pull of the SERPs on the domain). However, when I test certain URL's inside of WMT it still says that they are allowed which makes me think that it's not working fully or working at all. In this case these are the lines I've added to the robots.txt Disallow: /*&viagra Disallow: /*&Viagra I know I have the solution of individually requesting URL's to be removed from the index but I want to see if anybody has every had success with wildcarding URL's with a certain word in their robots.txt? The individual URL route could be very tedious. Thanks! Jon

Should I disallow all URL query strings/parameters in Robots.txt?
Webmaster Tools correctly identifies the query strings/parameters used in my URLs, but still reports duplicate title tags and meta descriptions for the original URL and the versions with parameters. For example, Webmaster Tools would report duplicates for the following URLs, despite it correctly identifying the "cat_id" and "kw" parameters: /Mulligan-Practitioner-CD-ROM
Intermediate & Advanced SEO | | jmorehouse
/Mulligan-Practitioner-CD-ROM?cat_id=87
/Mulligan-Practitioner-CD-ROM?kw=CROM Additionally, theses pages have self-referential canonical tags, so I would think I'd be covered, but I recently read that another Mozzer saw a great improvement after disallowing all query/parameter URLs, despite Webmaster Tools not reporting any errors. As I see it, I have two options: Manually tell Google that these parameters have no effect on page content via the URL Parameters section in Webmaster Tools (in case Google is unable to automatically detect this, and I am being penalized as a result). Add "Disallow: *?" to hide all query/parameter URLs from Google. My concern here is that most backlinks include the parameters, and in some cases these parameter URLs outrank the original. Any thoughts?0 -
Avoiding Duplicate Content with Used Car Listings Database: Robots.txt vs Noindex vs Hash URLs (Help!)
Hi Guys, We have developed a plugin that allows us to display used vehicle listings from a centralized, third-party database. The functionality works similar to autotrader.com or cargurus.com, and there are two primary components: 1. Vehicle Listings Pages: this is the page where the user can use various filters to narrow the vehicle listings to find the vehicle they want.
Intermediate & Advanced SEO | | browndoginteractive
2. Vehicle Details Pages: this is the page where the user actually views the details about said vehicle. It is served up via Ajax, in a dialog box on the Vehicle Listings Pages. Example functionality: http://screencast.com/t/kArKm4tBo The Vehicle Listings pages (#1), we do want indexed and to rank. These pages have additional content besides the vehicle listings themselves, and those results are randomized or sliced/diced in different and unique ways. They're also updated twice per day. We do not want to index #2, the Vehicle Details pages, as these pages appear and disappear all of the time, based on dealer inventory, and don't have much value in the SERPs. Additionally, other sites such as autotrader.com, Yahoo Autos, and others draw from this same database, so we're worried about duplicate content. For instance, entering a snippet of dealer-provided content for one specific listing that Google indexed yielded 8,200+ results: Example Google query. We did not originally think that Google would even be able to index these pages, as they are served up via Ajax. However, it seems we were wrong, as Google has already begun indexing them. Not only is duplicate content an issue, but these pages are not meant for visitors to navigate to directly! If a user were to navigate to the url directly, from the SERPs, they would see a page that isn't styled right. Now we have to determine the right solution to keep these pages out of the index: robots.txt, noindex meta tags, or hash (#) internal links. Robots.txt Advantages: Super easy to implement Conserves crawl budget for large sites Ensures crawler doesn't get stuck. After all, if our website only has 500 pages that we really want indexed and ranked, and vehicle details pages constitute another 1,000,000,000 pages, it doesn't seem to make sense to make Googlebot crawl all of those pages. Robots.txt Disadvantages: Doesn't prevent pages from being indexed, as we've seen, probably because there are internal links to these pages. We could nofollow these internal links, thereby minimizing indexation, but this would lead to each 10-25 noindex internal links on each Vehicle Listings page (will Google think we're pagerank sculpting?) Noindex Advantages: Does prevent vehicle details pages from being indexed Allows ALL pages to be crawled (advantage?) Noindex Disadvantages: Difficult to implement (vehicle details pages are served using ajax, so they have no tag. Solution would have to involve X-Robots-Tag HTTP header and Apache, sending a noindex tag based on querystring variables, similar to this stackoverflow solution. This means the plugin functionality is no longer self-contained, and some hosts may not allow these types of Apache rewrites (as I understand it) Forces (or rather allows) Googlebot to crawl hundreds of thousands of noindex pages. I say "force" because of the crawl budget required. Crawler could get stuck/lost in so many pages, and my not like crawling a site with 1,000,000,000 pages, 99.9% of which are noindexed. Cannot be used in conjunction with robots.txt. After all, crawler never reads noindex meta tag if blocked by robots.txt Hash (#) URL Advantages: By using for links on Vehicle Listing pages to Vehicle Details pages (such as "Contact Seller" buttons), coupled with Javascript, crawler won't be able to follow/crawl these links. Best of both worlds: crawl budget isn't overtaxed by thousands of noindex pages, and internal links used to index robots.txt-disallowed pages are gone. Accomplishes same thing as "nofollowing" these links, but without looking like pagerank sculpting (?) Does not require complex Apache stuff Hash (#) URL Disdvantages: Is Google suspicious of sites with (some) internal links structured like this, since they can't crawl/follow them? Initially, we implemented robots.txt--the "sledgehammer solution." We figured that we'd have a happier crawler this way, as it wouldn't have to crawl zillions of partially duplicate vehicle details pages, and we wanted it to be like these pages didn't even exist. However, Google seems to be indexing many of these pages anyway, probably based on internal links pointing to them. We could nofollow the links pointing to these pages, but we don't want it to look like we're pagerank sculpting or something like that. If we implement noindex on these pages (and doing so is a difficult task itself), then we will be certain these pages aren't indexed. However, to do so we will have to remove the robots.txt disallowal, in order to let the crawler read the noindex tag on these pages. Intuitively, it doesn't make sense to me to make googlebot crawl zillions of vehicle details pages, all of which are noindexed, and it could easily get stuck/lost/etc. It seems like a waste of resources, and in some shadowy way bad for SEO. My developers are pushing for the third solution: using the hash URLs. This works on all hosts and keeps all functionality in the plugin self-contained (unlike noindex), and conserves crawl budget while keeping vehicle details page out of the index (unlike robots.txt). But I don't want Google to slap us 6-12 months from now because it doesn't like links like these (). Any thoughts or advice you guys have would be hugely appreciated, as I've been going in circles, circles, circles on this for a couple of days now. Also, I can provide a test site URL if you'd like to see the functionality in action.0 -
Recovering from robots.txt error
Hello, A client of mine is going through a bit of a crisis. A developer (at their end) added Disallow: / to the robots.txt file. Luckily the SEOMoz crawl ran a couple of days after this happened and alerted me to the error. The robots.txt file was quickly updated but the client has found the vast majority of their rankings have gone. It took a further 5 days for GWMT to file that the robots.txt file had been updated and since then we have "Fetched as Google" and "Submitted URL and linked pages" in GWMT. In GWMT it is still showing that that vast majority of pages are blocked in the "Blocked URLs" section, although the robots.txt file below it is now ok. I guess what I want to ask is: What else is there that we can do to recover these rankings quickly? What time scales can we expect for recovery? More importantly has anyone had any experience with this sort of situation and is full recovery normal? Thanks in advance!

Disallowed Pages Still Showing Up in Google Index. What do we do?
We recently disallowed a wide variety of pages for www.udemy.com which we do not want google indexing (e.g., /tags or /lectures). Basically we don't want to spread our link juice around to all these pages that are never going to rank. We want to keep it focused on our core pages which are for our courses. We've added them as disallows in robots.txt, but after 2-3 weeks google is still showing them in it's index. When we lookup "site: udemy.com", for example, Google currently shows ~650,000 pages indexed... when really it should only be showing ~5,000 pages indexed. As another example, if you search for "site:udemy.com/tag", google shows 129,000 results. We've definitely added "/tag" into our robots.txt properly, so this should not be happening... Google showed be showing 0 results. Any ideas re: how we get Google to pay attention and re-index our site properly?

Should I prevent Google from indexing blog tag and category pages?
I am working on a website that has a regularly updated Wordpress blog and am unsure whether or not the category and tag pages should be indexable. The blog posts are often outranked by the tag and category pages and they are ultimately leaving me with a duplicate content issue. With this in mind, I assumed that the best thing to do would be to remove the tag and category pages from the index, but after speaking to someone else about the issue, I am no longer sure. I have tried researching online, but there isn't anything that provided any further information. Please can anyone with any experience of dealing with issues like this or with any knowledge of the topic help me to resolve this annoying issue. Any input will be greatly appreciated. Thanks Paul
