Best practice for disallowing URLS with Robots.txt
-
Hi Everybody,
We are currently trying to tidy up the crawling errors which are appearing when we crawl the site. On first viewing, we were very worried to say the least:17000+. But after looking closer at the report, we found the majority of these errors were being caused by bad URLs featuring:
- Currency - For example: "directory/currency/switch/currency/GBP/uenc/aHR0cDovL2NlbnR1cnlzYWZldHkuY29tL3dvcmt3ZWFyP3ByaWNlPTUwLSZzdGFuZGFyZHM9NzEx/"
- Color - For example: ?color=91
- Price - For example: "?price=650-700"
- Order - For example: ?dir=desc&order=most_popular
- Page - For example: "?p=1&standards=704"
- Login - For example: "customer/account/login/referer/aHR0cDovL2NlbnR1cnlzYWZldHkuY29tL2NhdGFsb2cvcHJvZHVjdC92aWV3L2lkLzQ1ODczLyNyZXZpZXctZm9ybQ,,/"
My question now is as a novice of working with Robots.txt, what would be the best practice for disallowing URLs featuring these from being crawled?
Any advice would be appreciated!

If you are looking to disallow url parameters you could use something like the following as a convention.
Disallow: /? or Disallow: /?dir=&order=&p= if you wanted to be more accurate with specific parameters. There have been a few Moz questions of this type over the last few years, if you do look to remove the parameters.
Also try and ensure that the product pages you have listed are well canonicalised and point to the original product etc. A good review on how to do this can be found here. This will in most cases be enough to remove any indexation/duplicate issues.

First I assume you have webmaster tools set up?
They have a robots.txt tester tool which you can test out different parameters to make sure you get the right syntax. For example color would be blocked by: Disallow: /?color=91* and you would follow that similar format more or less.
If you are confused I highly recommend reading through Moz's robots.txt best practices guide before you make any changes. Be sure to test all out in webmaster tools(search console)>robots.txt tester.
Let me know if you run into any problems.

Best SEO Practices for Displaying FAQs throughout site?
I've got an FAQ plugin (Ultimate FAQ) for a Wordpress site with tons of content (like 30 questions each with a page full, multi-paragraphs, of answers with good info -- stuff Google LOVES.) Right now, I have a main FAQ page that has 3 categories and about 10 questions under each category and each question is collapsed by default. You click an arrow to expand it to reveal the answer.I then have a single category's questions also displayed at the bottom of an appropriate related page. So the questions appear in two places on the site, always collapsed by default.Each question has a permalink that links to an individual page with only that question and answer.I know Google discounts (doesn't ignore) content that is hidden by default and requires a click (via js function) to reveal it.So what I'm wondering is if the way I have it setup is optimal for SEO? How is Google going to handle the questions being in essentially three places: it's own standalone page, in a list on a category page, and in a list on a page showing all questions for all categories. Should I make the questions not collapsed by default (which will make the master FAQ page SUPER long!)Does Google not mind the duplicate content within the site?What's the best strategy?

Using Meta Header vs Robots.txt
Hey Mozzers, I am working on a site that has search-friendly parameters for their faceted navigation, however this makes it difficult to identify the parameters in a robots.txt file. I know that using the robots.txt file is highly recommended and powerful, but I am not sure how to do this when facets are using common words such as sizes. For example, a filtered url may look like www.website.com/category/brand/small.html Brand and size are both facets. Brand is a great filter, and size is very relevant for shoppers, but many products include "small" in the url, so it is tough to isolate that filter in the robots.txt. (I hope that makes sense). I am able to identify problematic pages and edit the Meta Head so I can add on any page that is causing these duplicate issues. My question is, is this a good idea? I want bots to crawl the facets, but indexing all of the facets causes duplicate issues. Thoughts?

Hash URLs
Hi Mozzers, Happy Friday! I have a client that has created some really nice pages from their old content and we want to redirect the old ones to the new pages. The way the web developers have built these new pages is to use hashbang url's for example www.website.co.uk/product#newpage My question is can I redirect urls to these kind of pages? Would it be using the .htaccess file to do it? Thanks in advance, Karl

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

What Should I Do With My URL Names?
I release property on my blog each week, and it has come to the point we will get property in the same area as we have had in the past. So, I name my URL /blah-blah-blah-[area of property]/ for the first property in that area right. Now I get a different property in that same area and the URL will have to be named /blah-blah-blah-[area of property]-2/. Now I'm not sure if this is a major issue or not, but I'm sure there must be a better way than this, and I don't really want to take down our past properties - unless you can give me good reason too, of course? So before I start getting URLs like this: /blah-blah-blah-[area of property]-2334343534654/ (well, ok, maybe not that bad! But you get my point) I wanted to see what everyones opinion on it is 🙂 Thanks in advance!

Given a choice, for your #1 keyword, would you pick a .com with one or two hypens? (chicago-real-estate.com) or a .co with the full name as the url (chicagorealestate.co)? Is there an accepted best practice regarding hypenated urls and/or decent results regarding the effectiveness of the.co? Thank you in advance!
