Did you know that you can use a robots.txt file to control how search engines crawl and index your website? In this blog post, we'll explain what a robots.txt file is, how to use it, and the benefits of doing so. We'll also provide tips for creating a robots.txt file that will help you optimize your website's SEO. Stay tuned!
What's robots.txt?
Robots.txt is a file that lists all the rules for robots on crawling websites and what to ignore while crawling. This enables website owners to control which robots can index their site to keep some pages private even if they usually respect robots exclusion protocol (REP).
Why should I use robots.txt?
When you create a website, you likely want it to be found by as many people as possible. After all, the more people who see your site, the more chances you have of turning them into customers or clients. One way to make sure your site is easy to find is by using robots.txt files.
Robots.txt files are instructions for search engine robots to crawl and index your website pages. By telling robots which pages are not to crawl and index, you can keep certain areas of your website hidden from public view. This is especially useful if you have confidential information on your site that you don't want others to see.
Setting up robots.txt file
Setting up a robots.txt file is necessary for SEO (Search Engine Optimization). The robots.txt file tells the robots what to index and not index on a website. Robots.txt will increase or decrease your page rank, so you must follow these instructions carefully to create your robots.txt file correctly:
The robots.txt should be placed in the root directory of every site you want search engines such as Google and Bing Crawlers NOT to crawl through due to excessive crawling, which can lead to slowdowns in web browser response time and overall poor user experience.
You should start with an empty robot's.txt file at first, then add each blocked URL per line, one URL per line if possible, because it makes it easier to read and update the robots.txt file in the future.
The robots.txt file should be named robots.txt and not robots, just robots or any other name. This is because it's considered a best practice to name files and directories the way they're supposed to be. Robots are known as user agents, so robots txt makes more sense than robots.txt.
Before you add new URLs to your robots.txt file, make sure you search Google, for example, site:domainnamehere.com/robots.txt, so that you can get an idea of how many URLs are already blocked by existing rules in your robots txt file if there are any; otherwise, this will result in blocking of indexed pages that might still be required for your SEO and user experience.
Your robots.txt file should look like this:
User-agent: *
Disallow:/blog/
Allow: /css/ Allow: /wp-admin/ Disallow: /cgi-bin/
A robots.txt file is a small text file that gives directions to search engine robots. This robots.txt file tells robots whether they can go through the whole site or only certain parts of it and which files should be ignored. It's one of the first lines of defense in protecting your website from spamming and crawling since it means robots will avoid indexing pages you don't want to be indexed on Google's SERPs/search results page.
Spelling & grammar checker tools are available online. The robot's text file has to follow some pre-determined rules so that the robots know what they should do with all the data they find on your site.
If you're using WordPress for your content management system (CMS), robots.txt is usually found under your site's root directory.
How to create a robots txt file
When creating a robots.txt file, directories are denoted by forwarding slashes (/), e.g., /images/. In contrast, files are marked by their name followed by an asterisk ( * ), e.g., header*.jpg. This code tells robots to crawl the whole website and no directories or files within it - except those listed in another robots.txt section below:
User-agent: Googlebot
Disallow: /*?author=1
This robot's text file would then be saved as robots.txt and placed under wwwroot/themes/theme name/. Without that first line saying 'User-agent: Googlebot, however, robots will read robots.txt and see that they're intended to crawl everything, not just specific paths or files within site - which is more of a robot's exclusion protocol (REP).
Robots.txt is usually used for excluding pages from search engine robots and web spiders rather than blocking them completely since robots will still be able to visit your homepage if you want them to. You can also manually create robots' text files for each page on your site, so robots know exactly what should and shouldn't be indexed on the Google SERPs/search results page.
User-agent: *
Disallow: /Admin/*
Disallow: /login*
This robot's text file would then be saved as robots2txt and placed under wwwroot/ the robots txt file that you want robots to ignore.
Disallow: *.php
This robot's.txt file would then be saved as robots3txt and placed under wwwroot/themes/theme name/. Robots can read each robot's text file, taking precedence over robots2txt, which blocks access to admin pages. The third section says you don't want robots reading anything with a '.php' extension, which means they won't go through any scripts or PHP files that are part of your website's content management system (CMS) - e.g., WordPress, Joomla, etc.
How to upload the robots txt file
So you've created your robots.txt file - great! But now, what do you do with it? How can you ensure that it's uploaded to your website so that the robots can access it and follow your instructions?
Here are a few tips on how to upload the robots txt file:
- Check with your web host to see if they have an area where you can upload files, or check their support documentation for more information.
Suppose you're using a content management system (CMS) like WordPress. In that case, there may be plugins available that allow you to upload your robot's text file easily.
- You can also use FTP software to upload your robots.txt file directly to your website's root directory.
- Make sure to test your robots.txt file to ensure that it's working correctly. You can do this using the robot's txt validator tool on robots.txt Tester.
Uploading your robot's txt file is an essential step in helping to ensure that your website is accessible and search engine friendly. By following these tips, you can ensure that your robot's text file is correctly uploaded and functioning as intended.
Disadvantages of using Robots.txt
When misused, robots.txt can have many negative consequences for your website. Here are some of the main disadvantages to using robots.txt:
1) Your website may be penalized by Google.
Google uses robots.txt files to determine how much a website should be indexed and cached. If your robots.txt file is disallowing Google from indexing certain pages or directories, Google may penalize your website as a result. This could decrease traffic and lower search engine results page (SERPs) rankings.
2) You may lose out on potential web traffic.
Suppose you're preventing search engines from indexing certain pages or directories on your website. In that case, you're essentially cutting yourself off potential web traffic. Many users rely on search engines to find the information they need. If your website isn't ranking high in SERPs, you will likely lose potential visitors.
3) Your website may be less accessible to users.
If your website is robots.txt- ed, it will be much less accessible to users browsing the web using a search engine. This could lead to a decrease in conversion rates and an overall loss in revenue.
4) You may experience reduced website performance.
If you're blocking robots from indexing certain pages or directories on your website, it can result in reduced website performance. This is because search engine crawlers consume a lot of bandwidth, and your website may be performing slowly as a result.
5) You could lose data.
When robots crawl your site, they download any files linked to the robots.txt file (including HTML files). If you're robots.txt- ing these pages entirely, you'll lose all of the web page content associated with those files (e.g., product images on an eCommerce site or articles on a blog).
6) Your robots exclusion protocol file will be publicly visible.
Suppose you place your robots.txt file in the root directory of your website. In that case, it will appear in the source code for any page that it references—meaning that anyone can view them! Instead of placing robots.txt in your root directory, could you put it in a hidden directory instead?
7) Search engines will index your robot's exclusion protocol file.
Suppose you place robots.txt in your root directory. In that case, it will become part of web crawlers' index for any page that it references—meaning that the robots.txt file itself could get indexed and displayed by search engines! Instead of placing robots.txt in your root directory, could you put it in a hidden directory instead?
Remember a few key things when creating a robots.txt file for your website. Here are some of the most critical points:
Key Points To Remember while Setting up Robots.txt
1. The robots.txt file should be placed in the root directory of your website.
2. The robots.txt file must be named "robots.txt" and have no extension.
3. The robots.txt file must be formatted as plain text.
4. The robots.txt file can contain multiple lines, or rules, for robots to follow.
5. Each line in the robots.txt file should start with "User-agent:*
6. You can use the robots.txt file to deny access to certain parts of your website or to specify which pages robots are allowed to crawl.
7. If you don't have a robots.txt file, robots will assume that they can crawl all of your websites.
8. Always test your robots.txt file before publishing it live on your website.
9. robots.txt is case-sensitive, so be sure to use the correct capitalization when entering rules into the file.
10. The robots exclusion standard (the technical name for robots.txt) is maintained by the World Wide Web Consortium (W3C). For more information on robots.txt, visit their website at www.w3c.org/robots/ exclusion-standard/.
Conclusion
Remember, robots.txt is case sensitive, so be sure to use the correct casing when entering rules into the file. Also, robots.txt must be named robots.txt and have no extension. Ensure that you don't have robots/robots.txt instead of robots.txt by using an FTP client with a search function or manually checking your site's files before uploading robots.txt to your website; root directory with an FTP client program such as FileZilla, WinSCP, CuteFTP, etc... If robots are crawling parts of your site you'd rather they not see (such as wp-admin in WordPress), make sure the rule is in your robots file like "Disallow: /wp-admin/" and not "/wp-admin/."
Now that you know the basics of robots.txt go ahead and set it up on your website! robots.txt is a powerful tool to help keep your site organized and optimized for search engine crawlers.
