Partial Match or RegEx in Search Console's URL Parameters Tool?
-
So I currently have approximately 1000 of these URLs indexed, when I only want roughly 100 of them.
Let's say the URL is www.example.com/page.php?par1=ABC123=&par2=DEF456=&par3=GHI789=
All the indexed URLs follow that same kinda format, but I only want to index the URLs that have a par1 of ABC (but that could be ABC123 or ABC456 or whatever). Using URL Parameters tool in Search Console, I can ask Googlebot to only crawl URLs with a specific value. But is there any way to get a partial match, using regex maybe?
Am I wasting my time with Search Console, and should I just disallow any page.php without par1=ABC in robots.txt?
-
No problem
Hope you get it sorted!
-Andy

Thank you!
-
Haha, I think the train passed the station on that one. I would have realised eventually... XD
Thanks for your help!
-
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

Ah sorry I missed that bit!

Disallowing them would be my first priority really, before removing from index.
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.
-Andy
-
Yep, have done. (Briefly mentioned in my previous response.) Doesn't pass
-
I thought so too, but according to Google the trailing wildcard is completely unnecessary, and only needs to be used mid-URL.
-
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...)
-
My guess would be that this line needs an * at the end.
Allow: /page.php?par1=ABC* -
Sorry Martijn, just to jump in here for a second - Ria, you can test this via the Robots.txt testing tool in search console before going live to make sure it work.
-Andy

Hi Martijn, thanks for your response!
I'm currently looking at something like this...
**user-agent: *** #disallowing page.php and any parameters after it
disallow: /page.php #but leaving anything that starts with par1=ABC
allow: /page.php?par1=ABCI would have thought that you could disallow things broadly like that and give an exception, as you can with files in disallowed folders. But it's not passing Google's robots.txt Tester.
One thing that's probably worth mentioning really is that there are only two variables that I want to allow of the par1 parameter. For example's sake, ABC123 and ABC456. So would need to be either a partial match or "this or that" kinda deal, disallowing everything else.
-
Hi Ria,
I have never tried regular expressions in this way, so I can't tell you if this would work or not.
However, If all 1000 of these URL's are already indexed, just disallowing access won't then remove them from Google. You would ideally be able to place a noindex tag on those pages and let Google act on them, then you will be good to disallow. I am pretty sure there is no option to noindex under the URL Parameter Tool.
I hope that makes sense?
-Andy
-
Hi Ria,
What you could do, but it also depends on the rest of your structure is Disallow these urls based on the parameters (what you could do in a worst case scenario is that you would disallow all URLs and then put an exception Allow in there as well to make sure you still have the right URLs being indexed).
Martijn.

Over-optimizing Internal Linking: Is this real and, if so, what's the happy medium?
I have heard a lot about having a solid internal linking structure so that Google can easily discover pages and understand your page hierarchies and correlations and equity can be passed. Often, it's mentioned that it's good to have optimized anchor text, but not too optimized. You hear a lot of warnings about how over-optimization can be perceived as spammy: https://neilpatel.com/blog/avoid-over-optimizing/ But you also see posts and news like this saying that the internal link over-optimization warnings are unfounded or outdated:
Intermediate & Advanced SEO | | SearchStan
https://www.seroundtable.com/google-no-internal-linking-overoptimization-penalty-27092.html So what's the tea? Is internal linking overoptimization a myth? If it's true, what's the tipping point? Does it have to be super invasive and keyword stuffy to negatively impact rankings? Or does simple light optimization of internal links on every page trigger this?1 -
Can you disallow links via Search Console?
Hey guys, Is it possible in anyway to nofollow links via search console (not disavow) but just nofollow external links pointing to your site? Cheers.

Does Google Read URL's if they include a # tag? Re: SEO Value of Clean Url's
An ECWID rep stated in regards to an inquiry about how the ECWID url's are not customizable, that "an important thing is that it doesn't matter what these URLs look like, because search engines don't read anything after that # in URLs. " Example http://www.runningboards4less.com/general-motors#!/Classic-Pro-Series-Extruded-2/p/28043025/category=6593891 Basically all of this: #!/Classic-Pro-Series-Extruded-2/p/28043025/category=6593891 That is a snippet out of a conversation where ECWID said that dirty urls don't matter beyond a hashtag... Is that true? I haven't found any rule that Google or other search engines (Google is really the most important) don't index, read, or place value on the part of the url after a # tag.

Why is my client's site not ranking anymore? Like big time!
Ok, I'm reaching out to all of you Moz'rs for some help with this one. My client's site has dropped off the face of google in a real short period of time. It went from page 1 (avg rank 3 to page 6 (avg rank 50) and below in the matter of 2 weeks. Here's some facts: 1. DA is a 22 and homepage PA is a 31. It outranks all other sites in its competitive set. 2. The homepage used to be the page that displays for keyword searches, now its the FAQ page, which has a lower PA of 23. Why has the home page seemingly vaporized? And, why is the FAQ showing as the first result? What should I start checking. I feel paralyzed, not sure where to start. More info: a. There are no alerts present in Webmaster Tools. b. For some reason the homepage (domain.com) was 301'd to domain.com/home.html. Domain.com is indexed by Google, however, domain.com/home.html is not. If this is the issue, what is the best way to handle it? Thanks in advance for your help!

Brackets vs Encoded URLs: The "Same" in Google's eyes, or dup content?
Hello, This is the first time I've asked a question here, but I would really appreciate the advice of the community - thank you, thank you! Scenario: Internal linking is pointing to two different versions of a URL, one with brackets [] and the other version with the brackets encoded as %5B%5D Version 1: http://www.site.com/test?hello**[]=all&howdy[]=all&ciao[]=all
Intermediate & Advanced SEO | | mirabile
Version 2: http://www.site.com/test?hello%5B%5D**=all&howdy**%5B%5D**=all&ciao**%5B%5D**=all Question: Will search engines view these as duplicate content? Technically there is a difference in characters, but it's only because one version encodes the brackets, and the other does not (See: http://www.w3schools.com/tags/ref_urlencode.asp) We are asking the developer to encode ALL URLs because this seems cleaner but they are telling us that Google will see zero difference. We aren't sure if this is true, since engines can get so _hung up on even one single difference in character. _ We don't want to unnecessarily fracture the internal link structure of the site, so again - any feedback is welcome, thank you. 🙂0 -
May know what's the meaning of these parameters in .htaccess?

What's the best way to redirect categories & paginated pages on a blog?
I'm currently re-doing my blog and have a few categories that I'm getting rid of for housecleaning purposes and crawl efficiency. Each of these categories has many pages (some have hundreds). The new blog will also not have new relevant categories to redirect them to (1 or 2 may work). So what is the best place to properly redirect these pages to? And how do I handle the paginated URLs? The only logical place I can think of would be to redirect them to the homepage of the blog, but since there are so many pages, I don't know if that's the best idea. Does anybody have any thoughts?

Tool to calculate the number of pages in Google's index?
When working with a very large site, are there any tools that will help you calculate the number of links in the Google index? I know you can use site:www.domain.com to see all the links indexed for a particular url. But what if you want to see the number of pages indexed for 100 different subdirectories (i.e. www.domain.com/a, www.domain.com/b)? is there a tool to help automate the process of finding the number of pages from each subdirectory in Google's index?
