If my website do not have a robot.txt file, does it hurt my website ranking?
-
After a site audit, I find out that my website don't have a robot.txt. Does it hurt my website rankings? One more thing, when I type mywebsite.com/robot.txt, it automatically redirect to the homepage.
Please help!

One word answer: NO
Robots.txt informs search engine crawlers (bots) about which web pages should and should not be crawled and indexed. It uses directives like Allow and Disallow to specify these instructions.
If you haven't added a robots.txt file to your website, it generally means search engine crawlers will assume permission to crawl all your publicly accessible web pages.
This can have both positive and negative consequences:
Positive Impacts:
- Complete Indexing: All your web pages that are publicly available will likely be crawled and indexed by search engines, potentially improving your website's discoverability in search results.
Negative Impacts:
-
Unnecessary Crawling: Search engines might crawl pages that aren't valuable for search results, such as login pages, duplicate content, or temporary files. This can overload your server with unnecessary requests.
-
Confidentiality Issues: If you have any sensitive information on your website that shouldn't be publicly indexed (like internal documents or admin pages), it might get crawled without a robots.txt blocking it.
It's generally recommended to create a robots.txt file to:
- Prevent crawling of unimportant pages.
- list itemProtect confidential information.
- list itemInstruct crawlers on how to crawl your site efficiently.
Just for your reference check this website robots.txt.

Googlebot might not index all pages and blog posts unless you have a robot.txt. We added one to our garden office company website; we noticed organic seo improvements are within the month, we gained more sales.

Hi,
No, your website will work just fine without a robots.txt file.
Without a robots.txt file search engines will have a free run to crawl and index anything they find on the website. This is fine for most websites but it’s really good practice to at least point out where your XML sitemap is so search engines can find new content without having to slowly crawl through all the pages on your website and bumping into them days later.
It shouldn't go to homepage if mywebsite.com/robot.txt doesn't exist shoud go to custom 404 error page.
Hope this helps.
Thanks

Large robots.txt file
We're looking at potentially creating a robots.txt with 1450 lines in it. This will remove 100k+ pages from the crawl that are all old pages (I know, the ideal would be to delete/noindex but not viable unfortunately) Now the issue i'm thinking is that a large robots.txt will either stop the robots.txt from being followed or will slow our crawl rate down. Does anybody have any experience with a robots.txt of that size?

Will disallowing URL's in the robots.txt file stop those URL's being indexed by Google
I found a lot of duplicate title tags showing in Google Webmaster Tools. When I visited the URL's that these duplicates belonged to, I found that they were just images from a gallery that we didn't particularly want Google to index. There is no benefit to the end user in these image pages being indexed in Google. Our developer has told us that these urls are created by a module and are not "real" pages in the CMS. They would like to add the following to our robots.txt file Disallow: /catalog/product/gallery/ QUESTION: If the these pages are already indexed by Google, will this adjustment to the robots.txt file help to remove the pages from the index? We don't want these pages to be found.

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 -

Blocking Dynamic URLs with Robots.txt
Background: My e-commerce site uses a lot of layered navigation and sorting links. While this is great for users, it ends up in a lot of URL variations of the same page being crawled by Google. For example, a standard category page: www.mysite.com/widgets.html ...which uses a "Price" layered navigation sidebar to filter products based on price also produces the following URLs which link to the same page: http://www.mysite.com/widgets.html?price=1%2C250 http://www.mysite.com/widgets.html?price=2%2C250 http://www.mysite.com/widgets.html?price=3%2C250 As there are literally thousands of these URL variations being indexed, so I'd like to use Robots.txt to disallow these variations. Question: Is this a wise thing to do? Or does Google take into account layered navigation links by default, and I don't need to worry. To implement, I was going to do the following in Robots.txt: User-agent: * Disallow: /*? Disallow: /*= ....which would prevent any dynamic URL with a '?" or '=' from being indexed. Is there a better way to do this, or is this a good solution? Thank you!
