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

Robots.txt blocked internal resources Wordpress
Hi all, We've recently migrated a Wordpress website from staging to live, but the robots.txt was deleted. I've created the following new one: User-agent: *
Intermediate & Advanced SEO | | Mat_C
Allow: /
Disallow: /wp-admin/
Disallow: /wp-includes/
Disallow: /wp-content/plugins/
Disallow: /wp-content/cache/
Disallow: /wp-content/themes/
Allow: /wp-admin/admin-ajax.php However, in the site audit on SemRush, I now get the mention that a lot of pages have issues with blocked internal resources in robots.txt file. These blocked internal resources are all cached and minified css elements: links, images and scripts. Does this mean that Google won't crawl some parts of these pages with blocked resources correctly and thus won't be able to follow these links and index the images? In other words, is this any cause for concern regarding SEO? Of course I can change the robots.txt again, but will urls like https://example.com/wp-content/cache/minify/df983.js end up in the index? Thanks for your thoughts!2 -
Could another site copying my content hurt my ranking?
Earlier this week I asked why a page of mine might not be ranking locally. (https://moz.com/community/q/what-could-be-stopping-us-from-ranking-locally). Maybe this might be part of the answer – another firm has copied huge chunks of my website copy: **My company: **https://idearocketanimation.com/video-production-company/ The other company: http://studio3dm.com/studio3dm-com/video/ Could this be causing my page to not rank? And is there anything I can do about it, other than huff and puff to the other firm? (Which I am already doing.)

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.

Wildcarding Robots.txt for Particular Word in URL
Hey All, So I know that this isn't a standard robots.txt, I'm aware of how to block or wildcard certain folders but I'm wondering whether it's possible to block all URL's with a certain word in it? We have a client that was hacked a year ago and now they want us to help remove some of the pages that were being autogenerated with the word "viagra" in it. I saw this article and tried implementing it https://builtvisible.com/wildcards-in-robots-txt/ and it seems that I've been able to remove some of the URL's (although I can't confirm yet until I do a full pull of the SERPs on the domain). However, when I test certain URL's inside of WMT it still says that they are allowed which makes me think that it's not working fully or working at all. In this case these are the lines I've added to the robots.txt Disallow: /*&viagra Disallow: /*&Viagra I know I have the solution of individually requesting URL's to be removed from the index but I want to see if anybody has every had success with wildcarding URL's with a certain word in their robots.txt? The individual URL route could be very tedious. Thanks! Jon

Help! The website ranks fine but one of my web pages simply won't rank on Google!!!
One of our web pages will not rank on Google. The website as a whole ranks fine except just one section...We have tested and it looks fine...Google can crawl the page no problem. There are no spurious redirects in place. The content is fine. There is no duplicate page content issue. The page has a dozen product images (photos) but the load time of the page is absolutely fine. We have the submitted the page via webmaster and its fine. It gets listed but then a few hours later disappears!!! The site has not been penalised as we get good rankings with other pages. Can anyone help? Know about this problem?

We have two different websites with the same products and information, will that hurt our rankings?
We have two different domains, one for the UK and the other for the US, they have the exact same products, categories and information. (the information is almost the same in 400 products) We know that Google could recognize that as duplicate content, but will that actually hurt our rankings in both sites? Is it better if we create two completely different versions of the content on those pages?

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!
