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: /*?

How important is the file extension in the URL for images?
I know that descriptive image file names are important for SEO. But how important is it to include .png, .jpg, .gif (or whatever file extension) in the url path? i.e. https://example.com/images/golden-retriever vs. https://example.com/images/golden-retriever.jpg Furthermore, since you can set the filename in the Content-Disposition response header, is there any need to include the descriptive filename in the URL path? Since I'm pulling most of our images from a database, it'd be much simpler to not care about simulating a filename, and just reference an image id in my templates. Example: 1. Browser requests GET /images/123456

2. Server responds with image setting both Content-Disposition, and Link (canonical) headers Content-Disposition: inline; filename="golden-retriever"
Link: <https: 123456="" example.com="" images="">; rel="canonical"</https:>1 -
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

Image URLs - best practice
Hi - I'm assuming image URL best practice follows same principles as non image URLs (not too many files and so on) - I notice alot of web devs putting photos in subdomains, so wonder if I'm missing something (I usually avoid subdomains like the plague)!

Canonical URL & sitemap URL mismatch
Hi We're running a Magento store which doesn't have too much stock rotation. We've implemented a plugin that will allow us to give products custom canonical URLs (basically including the category slug, which is not possible through vanilla Magento). The sitemap feature doesn't pick up on these URLs, so we're submitting URLs to Google that are available and will serve content, but actually point to a longer URL via a canonical meta tag. The content is available at each URL and is near identical (all apart from the breadcrumbs) All instances of the page point to the same canonical URL We are using the longer URL in our internal architecture/link building to show this preference My questions are; Will this harm our visibility? Aside from editing the sitemap, are there any other signals we could give Google? Thanks

Where to put a page ID in a URL?
Hello, My company is going to change URLs to example.com/category or example.com/product. When we will change the URLs to product or category pages somehow we have to check whether the requested page is from category table in DB or from products table (this gives much speed to page load time). So we have to choose how to make the different product and category pages.

Programmers said that we need to insert id to URL. So the question is: Which is the better way to place an id to an URL? example.com/product-name?id=111 example.com/product-name/111 example.com/product_name-111 Or maybe we should use some other punctuation mark to separate id from product name? p.s. I have read Dynamic URLs vs. static URLs by Google and it still didn't answered which is the best for all of the pages. Somehow others solve this problem by typing only the names to the URL, but could anyone tell what that technology should be?0 -

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/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 -
Block an entire subdomain with robots.txt?
Is it possible to block an entire subdomain with robots.txt? I write for a blog that has their root domain as well as a subdomain pointing to the exact same IP. Getting rid of the option is not an option so I'd like to explore other options to avoid duplicate content. Any ideas?
