Should I block robots from URLs containing query strings?
-
I'm about to block off all URLs that have a query string using robots.txt. They're mostly URLs with coremetrics tags and other referrer info. I figured that search engines don't need to see these as they're always better off with the original URL.
Might there be any downside to this that I need to consider?
Appreciate your help / experiences on this one.
Thanks
Jenni

Thanks for your suggestions. I've already got canonical tags on every page, but they're not all being adhered to and lots of URLs with query strings are still getting organic traffic.
Passing referrer info behind scenes isn't an option with Coremetrics I don't think. Is it?
Interested to know more about number 1 though. How would you do that in WMT other than blocking with robots.txt?
Thanks

Instead of blocking them with robots.txt (which isn't very effective), try using the canonical tag instead.
For instance, a URL like this:
http://wwww.testdomain.com/page.html?utm_source=Google&utm_medium=Banner&utm_campaign=CampaignYou could add this canonical tag in the head:
With this solution you don't have to worry about losing quality links OR having your query tracking show up in any of the major search engines.
Cheers- Kyle

The downside to this would be if someone linked to the page with the query string, the search engines wouldn't crawl the page and flow link juice properly to the rest of your site.
Other options:
-
Use Google and Bing WMT to ignore those parameter query strings.
-
Make sure the canoncial tag is on those pages, pointing back to the version without the query string
-
Try to pass referrer info behind the scenes if possible

Old URLs Appearing in SERPs
Thirteen months ago we removed a large number of non-corporate URLs from our web server. We created 301 redirects and in some cases, we simply removed the content as there was no place to redirect to. Unfortunately, all these pages still appear in Google's SERPs (not Bings) for both the 301'd pages and the pages we removed without redirecting. When you click on the pages in the SERPs that have been redirected - you do get redirected - so we have ruled out any problems with the 301s. We have already resubmitted our XML sitemap and when we run a crawl using Screaming Frog we do not see any of these old pages being linked to at our domain. We have a few different approaches we're considering to get Google to remove these pages from the SERPs and would welcome your input. Remove the 301 redirect entirely so that visits to those pages return a 404 (much easier) or a 410 (would require some setup/configuration via Wordpress). This of course means that anyone visiting those URLs won't be forwarded along, but Google may not drop those redirects from the SERPs otherwise. Request that Google temporarily block those pages (done via GWMT), which lasts for 90 days. Update robots.txt to block access to the redirecting directories. Thank you. Rosemary One year ago I removed a whole lot of junk that was on my web server but it is still appearing in the SERPs.

Special characters in URL
Will registered trademark symbol within a URL be bad? I know some special characters are unsafe (#, >, etc.) but can not find anything that mentions registered trademark. Thanks!

Special characters in URL
Hi There, We're in the process of changing our URL structure to be more SEO friendly. Right now I'm struggling to find a good way to handle slashes that are part of a targeted keyword. For example, if I have a product page and my product title is "1/2 ct Diamond Earrings in 14K Gold" which of the following URLs is the right way to go if I'm targeting the product title as the search keyword? example.com/jewelry/1-2-ct-diamond-earrings-in-14k-gold example.com/jewelry/12-ct-diamond-earrings-in-14k-gold example.com/jewelry/1_2-ct-diamond-earrings-in-14k-gold example.com/jewelry/1%2F2-ct-diamond-earrings-in-14k-gold Thanks!

Block Baidu crawler?
Hello! One of our websites receives a large amount of traffic from the Baidu crawler. We do not have any Chinese content or do any business with China since our market is Uk. Is it a good idea to block the Baidu crawler in the robots.txt or could it have any adverse effects on SEO of our site? What do you suggest?

How do I check if my IP is blocked?
We changed servers and where our sites once ranked very highly (page 1 for all sites), they now are nowhere to be seen. Someone suggested that our IP might be blocked. Someone else suggested SEOMoz was the place to go to get it checked. Any help would be GREATLY appreciated. With thanks. Bryan

Can I Disallow Faceted Nav URLs - Robots.txt
I have been disallowing /*? So I know that works without affecting crawling. I am wondering if I can disallow the faceted nav urls. So disallow: /category.html/? /category2.html/? /category3.html/*? To prevent the price faceted url from being cached: /category.html?price=1%2C1000

Drupal URL Aliases vs 301 Redirects + Do URL Aliases create duplicates?
Hi all! I have just begun work on a Drupal site which heavily uses the URL Aliases feature. I fear that it is creating duplicate links. For example:: we have http://www.URL.com/index.php and http://www.URL.com/ In addition we are about to switch a lot of links and want to keep the search engine benefit. Am I right in thinking URL aliases change the URL, while leaving the old URL live and without creating search engine friendly redirects such as 301s? Thanks for any help! Christian

How to handle sitemap with pages using query strings?
Hi, I'm working to optimize a site that currently has about 5K pages listed in the sitemap. There are not in face this many pages. Part of the problem is that one of the pages is a tool where each sort and filter button produces a query string URL. It seems to me inefficient to have so many items listed that are all really the same page. Not to mention wanting to avoid any duplicate content or low quality issues. How have you found it best to handle this? Should I just noindex each of the links? Canonical links? Should I manually remove the pages from the sitemap? Should I continue as is? Thanks a ton for any input you have!
