Blocking Dynamic URLs with Robots.txt
-
Background:
My e-commerce site uses a lot of layered navigation and sorting links. While this is great for users, it ends up in a lot of URL variations of the same page being crawled by Google. For example, a standard category page:
...which uses a "Price" layered navigation sidebar to filter products based on price also produces the following URLs which link to the same page:
http://www.mysite.com/widgets.html?price=1%2C250
http://www.mysite.com/widgets.html?price=2%2C250
http://www.mysite.com/widgets.html?price=3%2C250
As there are literally thousands of these URL variations being indexed, so I'd like to use Robots.txt to disallow these variations.
Question:
-
Is this a wise thing to do? Or does Google take into account layered navigation links by default, and I don't need to worry.
-
To implement, I was going to do the following in Robots.txt:
User-agent: *
Disallow: /*?
Disallow: /*=
....which would prevent any dynamic URL with a '?" or '=' from being indexed. Is there a better way to do this, or is this a good solution?
Thank you!

If you are happy with any URLs with query strings not being indexed your robots.txt will work fine.
Do any or your URLs with question marks in them have links to them? If so you might want to be careful blocking google from indexing them. I would think you'd lose the benefits those links would pass to your site.

Tait,
Thanks for the answer. I think the canonical tag would be ideal, but in terms of implementation, it would require some substantial code modification to the site / PHP code as I have a lot of categories, and adding this manually to each one would be very time consuming.
Would preventing the spiders from indexing any URLs with a "?" or "&" (which would only be dynamic URLs variations) cause any problems? Or is this just not an ideal best practice?
Thanks!

I don't know if there's a good solution with robots.txt given your URL structure. However, you could use the rel=canonical link tag in the header to force google to treat many of your URLs the same way. This would help you avoid duplicate content penalties.

My url disappeared from Google but Search Console shows indexed. This url has been indexed for more than a year. Please help!
Super weird problem that I can't solve for last 5 hours. One of my urls: https://www.dcacar.com/lax-car-service.html Has been indexed for more than a year and also has an AMP version, few hours ago I realized that it had disappeared from serps. We were ranking on page 1 for several key terms. When I perform a search "site:dcacar.com " the url is no where to be found on all 5 pages. But when I check my Google Console it shows as indexed I requested to index again but nothing changed. All other 50 or so urls are not effected at all, this is the only url that has gone missing can someone solve this mystery for me please. Thanks a lot in advance.

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

Does having a ? on the end of your URL affect your SEO?
I have some redirects that were done with at "?" at the end of the URL to include google coding (i.e. you click on an adwords link and the google coding follows the redirected link). When there is not coding to follow the link just appears as "filename.html?". Will that affect us negatively SEO-wise? Thank you.

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 -
Robots.txt: Can you put a /* wildcard in the middle of a URL?
We have noticed that Google is indexing the language/country directory versions of directories we have disallowed in our robots.txt. For example: Disallow: /images/ is blocked just fine However, once you add our /en/uk/ directory in front of it, there are dozens of pages indexed. The question is: Can I put a wildcard in the middle of the string, ex. /en/*/images/, or do I need to list out every single country for every language in the robots file. Anyone know of any workarounds?

Removing dashes in our URLs?
Hi Forum, Our site has an errant product review module that is resulting in about 9-10 404 errors per day on Google Webmaster Tools. We've found that by changing our product page URLs to only include 2 dashes, the module stops causing 404 errors for that page. Does changing our URL from "oursite.com/girls-pink-yoga-capri.html" to "oursite.com/girlspink-yoga-capri.html" hurt our SEO for a search for "girls pink yoga capri"? If so, by how much (assuming everthing else on the page is optimized properly) Thanks for your input.

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?

URL Length or Exact Breadcrumb Navigation URL? What's More Important
Basically my question is as follows, what's better: www.romancingdiamonds.com/gemstone-rings/amethyst-rings/purple-amethyst-ring-14k-white-gold (this would fully match the breadcrumbs). or www.romancingdiamonds.com/amethyst-rings/purple-amethyst-ring-14k-white-gold (cutting out the first level folder to keep the url shorter and the important keywords are closer to the root domain). In this question http://www.seomoz.org/qa/discuss/37982/url-length-vs-url-keywords I was consulted to drop a folder in my url because it may be to long. That's why I'm hesitant to keep the bradcrumb structure the same. To the best of your knowldege do you think it's best to drop a folder in the URL to keep it shorter and sweeter, or to have a longer URL and have it match the breadcrumb structure? Please advise, Shawn
