Will disallowing URL's in the robots.txt file stop those URL's being indexed by Google
-
I found a lot of duplicate title tags showing in Google Webmaster Tools. When I visited the URL's that these duplicates belonged to, I found that they were just images from a gallery that we didn't particularly want Google to index. There is no benefit to the end user in these image pages being indexed in Google.
Our developer has told us that these urls are created by a module and are not "real" pages in the CMS.
They would like to add the following to our robots.txt file
Disallow: /catalog/product/gallery/
QUESTION: If the these pages are already indexed by Google, will this adjustment to the robots.txt file help to remove the pages from the index?
We don't want these pages to be found.
-
That's why I mentioned: "eventually". But thanks for the added information. Hopefully it's clear now for the original poster.

Looking at this video - https://www.youtube.com/watch?v=KBdEwpRQRD0&feature=youtu.be Matt Cutts advises to use the noindex tag on every individual page. However, this is very time consuming if you're dealing wit a large volume of pages.
The other option he recommends is to use the robots.txt file as well as the URL removal tool in GWMT, Although this is the second choice option, it does seem easier for us to implement than the noindex tag.

Hi,
Yes, if you put any url in the robots.txt it will not be shown in the search results after some time even if your pages were already indexed. Because when your disallow urls in the robots.txt , Google will stop crawling that page and eventually will stop indexing those pages.

Hi Nico
Great response thanks.
This is certainly something I'm taking into consideration and will question my developer about this.
-
Thanks Thomas.
I'm now finding out from my developer is we are able to noindex these pages with the meta robots.
If this is something that isn't possible, it's likely that we'll add to the robots.txt as you did.
Either way I think will be progress to different degrees.

I don' think Martijn's statement is quite correct as I have made different experiences in an accidental experiment. Crawling is not the same as indexing. Google will put pages it cannot crawl into the index ... and they will stay there unless removed somehow. They will probably only show up for specific searches, though
Completely agree, I have done the same for a website I am doing work with, ideally we would noindex with meta robots however that isn't possible. So instead we added to the robots.txt, the number of indexed pages have dropped, yet when you search exactly it just says the description can't be reached.
So I was happy with the results as they're now not ranking for the terms they were.

Google will put pages it cannot crawl into the index ... and they will stay there unless removed somehow. They will probably only show up for specific searches, though
In September 2015 I catapulted a website from ~3.000 to 130.000 indexed pages (roughly). 127.000 were essentially canonicalised duplicates (yes, it did make sense) but also blocked by robots.txt - but put into the index nonetheless. The problem was a dynamically generated parameter, always different, always blocked by robots.
The title was equal to the link text; the description became "A description for this result is not available because of this site's robots.txt – learn more." (If Google cannot crawl a URL Google will usually take titles from links pointing to that URL). No sign of disappearing. In fact, Google was happy to add more and more to its index ...
At the start of December 2015 I removed the robots.txt block - Google could now read the canonicals or noindex on the URLs ... the pages only began dropping out, slowly and in bunches of a few thousand in March 2016 - probably due to the very low relevancy and crawl budget assigned to them. Right now there are still about 24.000 pages in the index.
So my answer would be: No - disabling crawling in the robots.txt will NOT remove a page from the index. For that you need to noindex them (which sometimes also works if done in robots.txt, I've heard). Disallowing URLs in the robots.txt will very likely drop pages to the end of useful results, though, as Andy described. (I don't know if this has any influence on the general evaluation of the site as a whole; I'd guess not.)
Regards
Nico

Thanks Martijn. This is what I was assuming would happen. However, I got a confusing message from my developer which said the following,
"won't remove the URL's from the index but it will mean that they will only show up for very specific searches that customers are extremely unlikely to use. It will also increase Asgard's crawl budget as Google and Bing won't try to crawl these URLs. Would you be happy with this solution?"
I would tend to still agree with your statement though.
-
Yes they will be eventually. As you disallow Google to crawl the URLs it will probably start hiding the descriptions for some of these image pages soon as they can't crawl them anymore. Then at some point they'll stop looking at them at all.

What's the best possible URL structure for a local search engine?
Hi Mozzers, I'm working at AskMe.com which is a local search engine in India i.e if you're standing somewhere & looking for the pizza joints nearby, we pick your current location and share the list of pizza outlets nearby along with ratings, reviews etc. about these outlets. Right now, our URL structure looks like www.askme.com/delhi/pizza-outlets for the city specific category pages (here, "Delhi" is the city name and "Pizza Outlets" is the category) and www.askme.com/delhi/pizza-outlets/in/saket for a category page in a particular area (here "Saket") in a city. The URL looks a little different if you're searching for something which is not a category (or not mapped to a category, in which case we 301 redirect you to the category page), it looks like www.askme.com/delhi/search/pizza-huts/in/saket if you're searching for pizza huts in Saket, Delhi as "pizza huts" is neither a category nor its mapped to any category. We're also dealing in ads & deals along with our very own e-commerce brand AskMeBazaar.com to make the better user experience and one stop shop for our customers. Now, we're working on URL restructure project and my question to you all SEO rockstars is, what can be the best possible URL structure we can have? Assume, we have kick-ass developers who can manage any given URL structure at backend.

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 -
What are Soft 404's and are they a problem
Hi, I have some old pages that were coming up in google WMT as a 404. These had links into them so i thought i'd do a 301 back to either the home page or to a relevant category or page. However these are now listed in WMT as soft 404's. I'm not sure what this means and whether google is saying it doesn't like this? Any advice welcomed.

Our login pages are being indexed by Google - How do you remove them?
Each of our login pages show up under different subdomains of our website. Currently these are accessible by Google which is a huge competitive advantage for our competitors looking for our client list. We've done a few things to try to rectify the problem: - No index/archive to each login page Robot.txt to all subdomains to block search engines gone into webmaster tools and added the subdomain of one of our bigger clients then requested to remove it from Google (This would be great to do for every subdomain but we have a LOT of clients and it would require tons of backend work to make this happen.) Other than the last option, is there something we can do that will remove subdomains from being viewed from search engines? We know the robots.txt are working since the message on search results say: "A description for this result is not available because of this site's robots.txt – learn more." But we'd like the whole link to disappear.. Any suggestions?

Two Pages with the Same Name Different URL's
I was hoping someone could give me some insight into a perplexing issue that I am having with my website. I run an 20K product ecommerce website and I am finding it necessary to have two pages for my content: 1 for content category pages about wigets one for shop pages for wigets 1st page would be .com/shop/wiget/ 2nd page would be .com/content/wiget/ The 1st page would be a catalogue of all the products with filters for the customer to narrow down wigets. So ultimately the URL for the shop page could look like this when the customer filters down... .com/shop/wiget/color/shape/ The second page would be content all about the Wigets. This would be types of wigets colors of wigets, how wigets are used, links to articles about wigets etc. Here are my questions. 1. Is it bad to have two pages about wigets on the site, one for shopping and one for information. The issue here is when I combine my content wiget with my shop wiget page, no one buys anything. But I want to be able to provide Google the best experience for rankings. What is the best approach for Google and the customer? 2. Should I rel canonical all of my .com/shop/wiget/ + .com/wiget/color/ etc. pages to the .com/content/wiget/ page? Or, Should I be canonicalizing all of my .com/shop/wiget/color/etc pages to .com/shop/wiget/ page? 3. Ranking issues. As it is right now, I rank #1 for wiget color. This page on my site would be .com/shop/wiget/color/ . If I rel canonicalize all of my pages to .com/content/wiget/ I am going to loose my rankings because all of my shop/wiget/xxx/xxx/ pages will then point to .com/content/wiget/ page. I am just finding with these massive ecommerce sites that there is WAY to much potential for duplicate content, not enough room to allow Google the ability to rank long tail phrases all the while making it completely complicated to offer people pages that promote buying. As I said before, when I combine my content + shop pages together into one page, my sales hit the floor (like 0 - 15 dollars a day), when i just make a shop page my sales are like (1k+ a day). But I have noticed that ever since Penguin and Panda my rankings have fallen from #1 across the board to #15 and lower for a lot of my phrase with the exception of the one mentioned above. This is why I want to make an information page about wigets and a shop page for people to buy wigets. Please advise if you would. Thanks so much for any insight you can give me!

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?

Tool to calculate the number of pages in Google's index?
When working with a very large site, are there any tools that will help you calculate the number of links in the Google index? I know you can use site:www.domain.com to see all the links indexed for a particular url. But what if you want to see the number of pages indexed for 100 different subdirectories (i.e. www.domain.com/a, www.domain.com/b)? is there a tool to help automate the process of finding the number of pages from each subdirectory in Google's index?
