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

Hacked website - Dealing with 301 redirects and a large .htaccess file
One of my client's websites was recently hacked and I've been dealing with the after effects of it. The website is now clean of malware and I already appealed to Google about the malware issue. The current issue I have is dealing with the 20, 000+ crawl errors which are garbage links that were created from the hacking. How does one go about dealing with all the 301 redirects I need to create for all the 404 crawl errors? I'm already noticing an increased load time on the website due to having a rather large .htaccess file with a couple thousand 301 redirects done already which I fear will result in my client's website performance and SEO performance taking a hit as well.

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.

If Robots.txt have blocked an Image (Image URL) but the other page which can be indexed has this image, how is the image treated?
Hi MOZers, This probably is a dumb question but I have a case where the robots.tags has an image url blocked but this image is used on a page (lets call it Page A) which can be indexed. If the image on Page A has an Alt tags, then how is this information digested by crawlers? A) would Google totally ignore the image and the ALT tags information? OR B) Google would consider the ALT tags information? I am asking this because all the images on the website are blocked by robots.txt at the moment but I would really like website crawlers to crawl the alt tags information. Chances are that I will ask the webmaster to allow indexing of images too but I would like to understand what's happening currently. Looking forward to all your responses 🙂 Malika

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 -
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

How to handle a blog subdomain on the main sitemap and robots file?
Hi, I have some confusion about how our blog subdomain is handled in our sitemap. We have our main website, example.com, and our blog, blog.example.com. Should we list the blog subdomain URL in our main sitemap? In other words, is listing a subdomain allowed in the root sitemap? What does the final structure look like in terms of the sitemap and robots file? Specifically: **example.com/sitemap.xml ** would I include a link to our blog subdomain (blog.example.com)? example.com/robots.xml would I include a link to BOTH our main sitemap and blog sitemap? blog.example.com/sitemap.xml would I include a link to our main website URL (even though it's not a subdomain)? blog.example.com/robots.xml does a subdomain need its own robots file? I'm a technical SEO and understand the mechanics of much of on-page SEO.... but for some reason I never found an answer to this specific question and I am wondering how the pros do it. I appreciate your help with this.

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?

Soft 404's from pages blocked by robots.txt -- cause for concern?
We're seeing soft 404 errors appear in our google webmaster tools section on pages that are blocked by robots.txt (our search result pages). Should we be concerned? Is there anything we can do about this?
