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: /*?

Help with facet URLs in Magento
Hi Guys, Wondering if I can get some technical help here... We have our site britishbraces.co.uk , built in Magento. As per eCommerce sites, we have paginated pages throughout. These have rel=next/prev implemented but not correctly ( as it is not in is it in ) - this fix is in process. Our canonicals are currently incorrect as far as I believe, as even when content is filtered, the canonical takes you back to the first page URL. For example, http://www.britishbraces.co.uk/braces/x-style.html?ajaxcatalog=true&brand=380&max=51.19&min=31.19 Canonical to... http://www.britishbraces.co.uk/braces/x-style.html Which I understand to be incorrect. As I want the coloured filtered pages to be indexed ( due to search volume for colour related queries ), but I don't want the price filtered pages to be indexed - I am unsure how to implement the solution? As I understand, because rel=next/prev implemented ( with no View All page ), the rel=canonical is not necessary as Google understands page 1 is the first page in the series. Therefore, once a user has filtered by colour, there should then be a canonical pointing to the coloured filter URL? ( e.g. /product/black ) But when a user filters by price, there should be noindex on those URLs ? Or can this be blocked in robots.txt prior? My head is a little confused here and I know we have an issue because our amount of indexed pages is increasing day by day but to no solution of the facet urls. Can anybody help - apologies in advance if I have confused the matter. Thanks

Link juice through URL parameters
Hi guys, hope you had a fantastic bank holiday weekend. Quick question re URL parameters, I understand that links which pass through an affiliate URL parameter aren't taken into consideration when passing link juice through one site to another. However, when a link contains a tracking URL parameter (let's say gclid=), does link juice get passed through? We have a number of external links pointing to our main site, however, they are linking directly to a unique tracking parameter. I'm just curious to know about this. Thanks, Brett

Disallow URLs ENDING with certain values in robots.txt?
Is there any way to disallow URLs ending in a certain value? For example, if I have the following product page URL: http://website.com/category/product1, and I want to disallow /category/product1/review, /category/product2/review, etc. without disallowing the product pages themselves, is there any shortcut to do this, or must I disallow each gallery page individually?

Overly-Dynamic URL
Hi, We have over 5000 pages showing under Overly-Dynamic URL error Our ecommerce site uses Ajax and we have several different filters like, Size, Color, Brand and we therefor have many different urls like, http://www.dellamoda.com/Designer-Pumps.html?sort=price&sort_direction=1&use_selected_filter=Y http://www.dellamoda.com/Designer-Accessories.html?sort=title&use_selected_filter=Y&view=all http://www.dellamoda.com/designer-handbags.html?use_selected_filter=Y&option=manufacturer%3A&page3 Could we use the robots.txt file to disallow these from showing as duplicate content? and do we need to put the whole url in there? like: Disallow: /*?sort=price&sort_direction=1&use_selected_filter=Y if not how far into the url should be disallowed? 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. Any help would be greatly appreciated. Thank you,Kami

Google News URL Structure
Hi there folks I am looking for some guidance on Google News URLs. We are restructuring the site. A main traffic driver will be the traffic we get from Google News. Most large publishers use: www.site.com/news/12345/this-is-the-title/ Others use www.example.com/news/celebrity/12345/this-is-the-title/ etc. www.example.com/news/celebrity-news/12345/this-is-the-title/ www.example.com/celebrity-news/12345/this-is-the-title/ (Celebrity is a channel on Google News so should we try and follow that format?) www.example.com/news/celebrity-news/this-is-the-title/12345/ www.example.com/news/celebrity-news/this-is-the-title-12345/ (unique ID no at the end and part of the title URL) www.example.com/news/celebrity-news/celebrity-name/this-is-the-title-12345/ Others include the date. So as you can see there are so many combinations and there doesnt seem to be any unity across news sites for this format. Have you any advice on how to structure these URLs? Particularly if we want to been seen as an authority on the following topics: fashion, hair, beauty, and celebrity news - in particular "celebrity name" So should the celebrity news section be www.example.com/news/celebrity-news/celebrity-name/this-is-the-title-12345/ or what? This is for a completely new site build. Thanks Barry

Using 2 wildcards in the robots.txt file
I have a URL string which I don't want to be indexed. it includes the characters _Q1 ni the middle of the string. So in the robots.txt can I use 2 wildcards in the string to take out all of the URLs with that in it? So something like /_Q1. Will that pickup and block every URL with those characters in the string? Also, this is not directly of the root, but in a secondary directory, so .com/.../_Q1. So do I have to format the robots.txt as //_Q1* as it will be in the second folder or just using /_Q1 will pickup everything no matter what folder it is on? Thanks.

Blocking HTTP 1.0?
One of my clients believes someone is trying to hack their site. We are seeing the requests with a server protocol or HTTP 1.0 so they want to block 1.0 entirely. Will this cause any problems with search engines or regular, non-spamming visitors?

Is it safe to redirect multiple URLs to a single URL?
Hi, I have an old Wordress website with about 300-400 original pages of content on it. All relating to my company's industry: travel in Africa. It's a legitimate site with travel stories, photos, advice etc. Nothing spammy about. No adverts on it. No affiliates. The site hasn't been updated for a couple of years and we no longer have a need for it. Many of the stories on it are quite out of date. The site has built up a modest Mozrank value over the last 5 years, and has a few hundreds organically achieved inbound links. Recently I set up a swanky new branded website on ExpressionEngine on a new domain. My intention is to: Shut down the old site Focus all attention on building up content on the new website Ask the people linking to the old site to my new site instead (I wonder how many will actually do so...) Where possible, setup a 301 redirect from pages on the old site to their closest match on the new site Setup a 301 redirect from the old site's home page to new site's homepage Sounds good, right? But there is one issue I need some advice on... The old site has about 100 pages that do not have a good match on the new site. These pages are outdated or inferior quality, so it doesn't really make sense to rewrite them and put them on the new site. I call these my "black sheep pages". So... for these "black sheep pages" should I (A) redirect the urls to the new site's homepage (B) redirect the urls the old site's home page (which in turn, redirects to the new site's homepage, or (C) not redirect the urls, and let them die a lonely 404 death? OPTION A: oldsite.com/page1.php -> newsite.com

oldsite.com/page3.php -> oldsite.com
oldsite.com/page4.php -> oldsite.com
oldsite.com/page5.php -> oldsite.com
oldsite.com -> newsite.com OPTION 😄 oldsite.com/page1.php : do not redirect, let page 404 and disappear forever
oldsite.com/page2.php : do not redirect, let page 404 and disappear forever
oldsite.com/page3.php : do not redirect, let page 404 and disappear forever
oldsite.com/page4.php : do not redirect, let page 404 and disappear forever
oldsite.com/page5.php : do not redirect, let page 404 and disappear forever
oldsite.com -> newsite.com My intuition tells me that Option A would pass the most "link juice" to my new site, but I am concerned that it could also be seen by Google as a spammy redirect technique. What would you do? Help 😐1
