What does Disallow: /french-wines/?* actually do - robots.txt
-
Hello Mozzers - Just wondering what this robots.txt instruction means: Disallow: /french-wines/?*
Does it stop Googlebot crawling and indexing URLs in that "French Wines" folder - specifically the URLs that include a question mark?
Would it stop the crawling of deeper folders - e.g. /french-wines/rhone-region/ that include a question mark in their URL?
I think this has been done to block URLs containing query strings.
Thanks, Luke

Glad to help, Luke!

Thanks Logan for your help with this - much appreciated. Really helpful!

Disallow: /?* is the same thing as Disallow:/?, since the asterisk is a wildcard, both of those disallows prevent any URL that begins with /? from being crawled.
And yes, it is incredibly easy to disallow the wrong thing! The robots.txt tester in Search Console (under the Crawl menu) is very helpful for figuring out what a disallow will catch and what it will let by. I highly recommend testing any new disallows there before releasing them into the wild.

Thanks again Logan.
What would Disallow: /?* do because that is what the site I am looking at has implemented. Perhaps it works both ways around?
I imagine it's easy to disallow the wrong thing or possibly not disallow the right thing. Ugh.

Disallow: /*?
This disallow literally says to crawlers 'if a URL starts with a slash (all URLs) and has a parameter, don't crawl it'. The * is a wildcard that says anything between / and ? is applicable to the disallow.
It's very easy to disallow the wrong this especially in regards to parameters, for this reason I always do these 2 things rather than using robots.txt:
- Set the purpose of each parameter in Search Console - Go to Crawl > URL Parameters to configure for your site
- Self-referring canonicals - most people disallow URLs with parameters in robots.txt to prevent indexing, but this only prevents crawling. A self-referring canonical pointing to the root level of that URL will prevent indexing or URLs with parameters.
Hope that's helpful!

Thanks Logan - I was just reading: Disallow: /*? # block any URL that includes a ? (and thus a query string) - do you know why the ? comes before the * in this case?

Hi Luke,
You are correct that this was done to block URLs with parameters. However, since there's no wildcard (the asterisk) before the folder name, the URL would have to start with /french-wines/. This disallow is really only preventing crawling on the single URL www.yoursite.com/french-wines/ with any parameters appended.

Readd/Reindex a page that was 410'd
A script of ours had an error that caused some pages we didn't wish 410'd to be 410'd, we caught it in about 12 hours but for some pages it was too late. My question is, will those pages be reindexed again and how will that affect their page ranking will they eventually be back where they were? Would submitting a site map with them help, or what would be the best way to correct this error (submit the links to google indexer maybe?).

Should I disallow all URL query strings/parameters in Robots.txt?
Webmaster Tools correctly identifies the query strings/parameters used in my URLs, but still reports duplicate title tags and meta descriptions for the original URL and the versions with parameters. For example, Webmaster Tools would report duplicates for the following URLs, despite it correctly identifying the "cat_id" and "kw" parameters: /Mulligan-Practitioner-CD-ROM
Intermediate & Advanced SEO | | jmorehouse
/Mulligan-Practitioner-CD-ROM?cat_id=87
/Mulligan-Practitioner-CD-ROM?kw=CROM Additionally, theses pages have self-referential canonical tags, so I would think I'd be covered, but I recently read that another Mozzer saw a great improvement after disallowing all query/parameter URLs, despite Webmaster Tools not reporting any errors. As I see it, I have two options: Manually tell Google that these parameters have no effect on page content via the URL Parameters section in Webmaster Tools (in case Google is unable to automatically detect this, and I am being penalized as a result). Add "Disallow: *?" to hide all query/parameter URLs from Google. My concern here is that most backlinks include the parameters, and in some cases these parameter URLs outrank the original. Any thoughts?0 -
Citation/Business Directory Question...
A company I work for has two numbers... one for the std call centre and one for tracking SEO. Now, if local citation/business directory listings have the same address but different numbers, will this affect local/other SEO results? Any help is greatly appreciated! 🙂

Should you include domain / brand in Meta Title
Hello, I am trying to come up with a strategy for creating meta title information for my eCommerce store. I have read mixed reviews on the examples below. The first includes the company / brand in the meta title and thus is included in SE results. The second does not. Probably not a 'right' answer here so I look forward to answers with rationale... also open to a completely difference strategy all together! 1MR Vortex by BPI Sports - $Company_Name OR 1MR Vortex by BPI Sports - Pre Workout Supplement Thanks!

Robots.txt, does it need preceding directory structure?
Do you need the entire preceding path in robots.txt for it to match? e.g: I know if i add Disallow: /fish to robots.txt it will block /fish
Intermediate & Advanced SEO | | Milian
/fish.html
/fish/salmon.html
/fishheads
/fishheads/yummy.html
/fish.php?id=anything But would it block?: en/fish
en/fish.html
en/fish/salmon.html
en/fishheads
en/fishheads/yummy.html
**en/fish.php?id=anything (taken from Robots.txt Specifications)** I'm hoping it actually wont match, that way writing this particular robots.txt will be much easier! As basically I'm wanting to block many URL that have BTS- in such as: http://www.example.com/BTS-something
http://www.example.com/BTS-somethingelse
http://www.example.com/BTS-thingybob But have other pages that I do not want blocked, in subfolders that also have BTS- in, such as: http://www.example.com/somesubfolder/BTS-thingy
http://www.example.com/anothersubfolder/BTS-otherthingy Thanks for listening0 -
Ending URLs in .html versus /
Hi there! Currently all the URLs on my website, even the home page, end it .html, such as http://www,consumerbase.com/index.html Is this bad?
Intermediate & Advanced SEO | | Travis-W
Is there any benefit to this? Should I remove it and just have them end with a forward slash?
If I 301 redirect the old .html URLs to the forward slash URLs, will I lose PA? Thanks!0
