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.

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

Should I canonicalize URLs with no query params even though query params are always automatically appended?
There's a section of my client's website that presents quarterly government financial data. Users can filter results to see different years and quarters of financial info. If a user navigates to those pages, the URLs automatically append the latest query parameters. It's not a redirect...when I asked a developer what the mechanism was for this happening, he said "magic." He honestly didn't know how to describe it. So my question is, is it ok to canonicalize the URL without any query parameters, knowing that the user will always be served a page that does have query parameters? I need to figure out how to manage all of the various versions of these URLs.

Is sitemap required on my robots.txt?
Hi, I know that linking your sitemap from your robots.txt file is a good practice. Ok, but... may I just send my sitemap to search console and forget about adding ti to my robots.txt? That's my situation: 1 multilang platform which means... ... 2 set of pages. One for each lang, of course But my CMS (magento) only allows me to have 1 robots.txt file So, again: may I have a robots.txt file woth no sitemap AND not suffering any potential SEO loss? Thanks in advance, Juan Vicente Mañanas Abad

Should I block Map pages with robots.txt?
Hello, I have a website that was started in 1999. On the website I have map pages for each of the offices listed on my site, for which there are about 120. Each of the 120 maps is in a whole separate html page. There is no content in the page other than the map. I know all of the offices love having the map pages so I don't want to remove the pages. So, my question is would these pages with no real content be hurting the rankings of the other pages on our site? Therefore, should I block the pages with my robots.txt? Would I also have to remove these pages (in webmaster tools?) from Google for blocking by robots.txt to really work? I appreciate your feedback, thanks!

Blocked URL parameters can still be crawled and indexed by google?
Hy guys, I have two questions and one might be a dumb question but there it goes. I just want to be sure that I understand: IF I tell webmaster tools to ignore an URL Parameter, will google still index and rank my url? IS it ok if I don't append in the url structure the brand filter?, will I still rank for that brand? Thanks, PS: ok 3 questions :)...

Cyrillic letter in URL - Encoding
Hi all We are launching our site in Russia. As far as I can see by searching Google all sites have URLs in latin letters. Is there a special reason for this? - It seems that cyrillic letters also work. My technical staff says that it might give some encoding problems. Can anyone give me some insight into this? Thanks in advance.. / Kenneth

Trailing Slashes In Url use Canonical Url or 301 Redirect?
I was thinking of using 301 redirects for trailing slahes to no trailing slashes for my urls. EG: www.url.com/page1/ 301 redirect to www.url.com/page1 Already got a redirect for non-www to www already. Just wondering in my case would it be best to continue using htacces for the trailing slash redirect or just go with Canonical URLs?

Block a sub-domain from being indexed
This is a pretty quick and simple (i'm hoping) question. What is the best way to completely block a sub domain from getting indexed from all search engines? One item i cannot use is the meta "no follow" tag. Thanks! - Kyle
