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

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 -

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 : ![Red ford truck](2554.jpg) changed to ![Red ford truck](6842.jpg)

Is it normal to initially rank low in the SERPs, then over time gain rank?
We just released a very targeted page for a specific item about 18 hours ago. For the main keyword as well as multiple variations, we currently are ranking around # 40 to # 50 depending on what the exact query is. Is it normal to initially rank lower in the SERPs and then as the page ages, gain? Thank you for your insights!

Robots.txt: how to exclude sub-directories correctly?
Hello here, I am trying to figure out the correct way to tell SEs to crawls this: http://www.mysite.com/directory/ But not this: http://www.mysite.com/directory/sub-directory/ or this: http://www.mysite.com/directory/sub-directory2/sub-directory/... But with the fact I have thousands of sub-directories with almost infinite combinations, I can't put the following definitions in a manageable way: disallow: /directory/sub-directory/ disallow: /directory/sub-directory2/ disallow: /directory/sub-directory/sub-directory/ disallow: /directory/sub-directory2/subdirectory/ etc... I would end up having thousands of definitions to disallow all the possible sub-directory combinations. So, is the following way a correct, better and shorter way to define what I want above: allow: /directory/$ disallow: /directory/* Would the above work? Any thoughts are very welcome! Thank you in advance. Best, Fab.

Splitting one Website into 2 Different New Websites with 301 redirects, help?
Here's the deal. My website stbands.com does fairly well. The only issue it is facing a long term branding crisis. It sells custom products and sporting goods. We decided that we want to make a sporting goods website for the retail stuff and then a custom site only focusing on the custom stuff. One website transformed and broken into 2 new ones, with two new brand names. The way we are thinking about doing this is doing a lot of 301 redirects, but what do we do with the homepage (stbands.com) and what is the best practice to make sure we don't lose traffic to the categories, etc.? Which new website do we 301 the homepage to? It's rough because for some keywords we rank 3 or 4 times on the first page. Scary times, but something must be done for the long term. Any advise is greatly appreciated. Thank you in advance. We are set for a busy next few months 🙂
