Partial Match or RegEx in Search Console's URL Parameters Tool?

[Martijn_Scheijbeler]

My guess would be that this line needs an * at the end.
Allow: /page.php?par1=ABC*

Hi Andy,

Disallowing them would be my first priority really, before removing from index. Didn't want to remove them before I've blocked Google from crawling them in case they get added back again next time Google comes a-crawling, as has happened before when I've simply removed a URL here and there. Does that make sense or am I getting myself mixed up here?

My other hack of a solution would be to check the URL in the page.php, and if URL includes par1=ABC then insert noindex meta tag. (Not sure if that would work well or not...)

I thought so too, but according to Google the trailing wildcard is completely unnecessary, and only needs to be used mid-URL.

[Ria_]

Yep, have done. (Briefly mentioned in my previous response.) Doesn't pass

The trouble with this is that if you disallow first, Google won't be able to crawl the page to act on the noindex. If you add a noindex flag, Google won't index them the next time it comes-a-crawling and then you will be good to disallow

I'm not actually sure of the best way for you to get the noindex in to the page header of those pages though.

Ah sorry I missed that bit!

Don't forget that . & ? have a specific meaning within regex - if you want to use them for pattern matching you will have to escape them. Also be aware that not all bots are capable of interpreting regex in robots.txt - you might want to be more explicit on the user agent - only using regex for Google bot.

User-agent: Googlebot

#disallowing page.php and any parameters after it

disallow: /page.php

#but leaving anything that starts with par1=ABC

allow: page.php?par1=ABC

Haha, I think the train passed the station on that one. I would have realised eventually... XD

Thanks for your help!

[Ria_]

Thank you!

[Andy.Drinkwater]

No problem

Hope you get it sorted!
