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

What to do with PDFs that rank well?
Looking at some reports, I found that a client's site has PDFs that are ranking well for niche terms and getting some traffic. What can I do to get more out of them from a marketing standpoint? The obvious issue is that a PDF doesn't have the interactivity of a site visit, where we have analytics and CTAs. Someone has to follow a link back from the PDF to the site for us to even register a visit, let alone try to get their email or have them otherwise convert. My first guess is to make landing page summaries of the PDF content that link to the PDF, and canonical the PDF to the respective landing page. Has anyone tried this, or done something else that they would recommend again in this situation?

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

Would changing the file name of an image (not the alt attribute) have an effect of on seo / ranking of that image and thus the site?
Would changing the file name of image, not the alt attribute nor the image itself (so it would be exactly the same but just a name change) have any effect on : a) A sites seo ranking b) the individual images seo ranking (although i guess if b) would be true it would have an effect on a) although potentially small.) This is the sort of change i would be thinking of making :  changed to

Does blocking foreign country IP traffic to site, hurt my SEO / US Google rankings?
I have a website is is only of interest to US visitors. 99% (at least) of Adsense income is from the US. But I'm getting constant attempts by hackers to login to my admin account. I have countermeasures fo combat that and am initiating others. But here's my question: I am considering not allowing any non US, or at least any non-North American, traffic to the site via a Wordpress plugin that does this. I know it will not affect my business negatively, directly. However, are there any ramifications of the Google bots of these blocked countries not being able to access my site? Does it affect the rankings of my site in the US Google searches. At the very least I could block China, Russia and some eastern European countries.

Using 2 wildcards in the robots.txt file
I have a URL string which I don't want to be indexed. it includes the characters _Q1 ni the middle of the string. So in the robots.txt can I use 2 wildcards in the string to take out all of the URLs with that in it? So something like /_Q1. Will that pickup and block every URL with those characters in the string? Also, this is not directly of the root, but in a secondary directory, so .com/.../_Q1. So do I have to format the robots.txt as //_Q1* as it will be in the second folder or just using /_Q1 will pickup everything no matter what folder it is on? Thanks.
