Block session id URLs with robots.txt
-
Hi,
I would like to block all URLs with the parameter '?filter=' from being crawled by including them in the robots.txt.
Which directive should I use:
User-agent: *
Disallow: ?filter=or
User-agent: *
Disallow: /?filter=In other words, is the forward slash in the beginning of the disallow directive necessary?
Thanks!
-
Hi Martijn,
Thanks for the answer. Regarding the forward slash in the beginning, is it necessary to use this?
In the robots text from Zalando for example, you can see that they don't use it for a lot of filters.
-
Uhh, that's not what the requester is looking for and could actually cause tons of problems if you would apply this on a site that you're unaware of. I would always go with the most limiting robots.txt that you can and in this case, I would go with: /?filter=
-
Hi,
The following should suffice as it will black any URL with a "?" in it
User-agent: * Disallow: /*?

Will Reduced Bounce Rate, Increased Pages/Session, Increased Session Duration-RESULT IN BETTER RANKING?
Our relaunched website has a much lower bounce rate (66% before, now 58%) increased pages per session (1.89 before, now 3.47) and increased session duration (1:33 before, now 3:47). The relaunch was December 20th. Should these improvements result in an improvement in Google rank? How about in MOZ authority? We have not significantly changed the content of the site but the UX has been greatly improved. Thanks, Alan

All URLs in the site is 302 redirected to itself
Hi everyone, I have a problem with a website wherein all URLs (homepage, inner pages) are 302 redirected. This is based on Screaming Frog crawl. But the weird thing is that they are 302 redirected to themselves which doesn't make any sense. Example:
Intermediate & Advanced SEO | | alex_goldman
https://www.example.com.au/ is 302 redirected to https://www.example.com.au/ https://www.example.com.au/shop is 302 redirected to https://www.example.com.au/shop https://www.example.com.au/shop/dresses is 302 redirected to https://www.example.com.au/shop/dresses Have you encountered this issue? What did you do to fix it? Would be very glad to hear your responses. Cheers!0 -
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?

URL Injection Hack - What to do with spammy URLs that keep appearing in Google's index?
A website was hacked (URL injection) but the malicious code has been cleaned up and removed from all pages. However, whenever we run a site:domain.com in Google, we keep finding more spammy URLs from the hack. They all lead to a 404 error page since the hack was cleaned up in the code. We have been using the Google WMT Remove URLs tool to have these spammy URLs removed from Google's index but new URLs keep appearing every day. We looked at the cache dates on these URLs and they are vary in dates but none are recent and most are from a month ago when the initial hack occurred. My question is...should we continue to check the index every day and keep submitting these URLs to be removed manually? Or since they all lead to a 404 page will Google eventually remove these spammy URLs from the index automatically? Thanks in advance Moz community for your feedback.

Removing UpperCase URLs from Indexing
This search - site:www.qjamba.com/online-savings/automotix gives me this result from Google: Automotix online coupons and shopping - Qjamba
Intermediate & Advanced SEO | | friendoffood
https://www.qjamba.com/online-savings/automotix
Online Coupons and Shopping Savings for Automotix. Coupon codes for online discounts on Vehicles & Parts products. and Google tells me there is another one, which is 'very simliar'. When I click to see it I get: Automotix online coupons and shopping - Qjamba
https://www.qjamba.com/online-savings/Automotix
Online Coupons and Shopping Savings for Automotix. Coupon codes for online discounts on Vehicles & Parts products. This is because I recently changed my program to redirect all urls with uppercase in them to lower case, as it appears that all lowercase is strongly recommended. I assume that having 2 indexed urls for the same content dilutes link juice. Can I safely remove all of my UpperCase indexed pages from Google without it affecting the indexing of the lower case urls? And if, so what is the best way -- there are thousands.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 -

So far we have added the following to our robots,txt Disallow: /?sort=title Disallow: /?use_selected_filter=Y Disallow: /?sort=price Disallow: /?clearall=Y Just not sure if they are correct.
