“Robots Exclusion Protocol” or robots.txt file is a file that tells instruct web crawlers and search engine bots on how to interact with their site’s content and page. A robots txt generator can generate robot file that will help you to gain managing website indexing, improving search engine optimization (SEO), and safeguarding sensitive information from unwanted exposure. In this article, we’ll learn the various aspects of the Robots.txt file and we will create a robots txt file generator using html, CSS and JavaScript including its advantages, disadvantages, security implications, potential problems, and the world of bots.
A robots.txt file is located in the root or public_html directory of your website. This directory will represent your website for web crawlers. It is a plain text file that contains a list of directives of website path, each of which tells a bot what it can and cannot do.
The most common directives are:
- User-agent: This command or instruction tells the bot which crawler the instructions are for. For example, User-agent: Googlebot tells Googlebot which page or website path to follow.
- Disallow: This directive tells the bot to not crawl a specific path or file. For example, Disallow: /private/bank_data tells Googlebot not to crawl the /private/bank_data directory.
- Allow: This directive tells the bot to crawl a specific path or file. For example, Allow: /public/ tells Googlebot to crawl the /public/ directory.
- Sitemap: Site map instruction told a bot that while your sitemap are available for this website. Example Sitemap: https://example.com/sitemap.xml
Analysis of robots file :
- Web Crawlers: Bots like Googlebot, Bingbot, and other search engine crawlers are used to visit your website in every day and generate a index file for their search engine. That’s why we can control “Web Crawlers” by using robots.txt file. We can give access any bot to use our website or we can disallow a bot to access our website or web page.
- Bad Bots: Malicious bots (a kind of bot that used for various security virus spreading reason), often used for web scraping (this bot can copy our website data and use their own Preferences), spamming, or launching cyberattacks, can cause harm to websites and users.
- Good Bots: Some bots, like chatbots and web assistants, provide helpful and interactive features to enhance user experience and provide analysis data through the website owner. Or upset owner can analyze these data and enhance the experience of their website and the users.
- Analysis Bots: There are some boat like Uber suggest, small seo tool, semrush seo tool will scan your website for their own benefits. Therefore, you can disallow this analysis bot using robots txt file.
Advantages of Robots.txt:
- Improving search engine optimization is the most benefit of Robots.txt file. By controlling hot files are indexed, can be very easy for search engine bot to recognize your files and articles.

- Enhancing user experience is another great thing that we can do using Robots.txt.
Disadvantages of Robots.txt:
- Robots.txt formats are not supported for all the bots. That’s why it’s a lack of information that can be produced a new problem for website owner and users.
- Security Through Obscurity is another main problem for using robots.txt. We can disclose our private information to public area.
- Robots.txt does not have big opportunity to solve every problem that includes in “Web Crawlers”.
- There are also some security and privacy problem for using robots.txt. A normal user can see the private path or folder that includes in robot.txt file.

Code For Blogger And WordPress :
You can create robot.txt generator for blogger and WordPress and any other website. Just Follow the Step :
- In head section you can put CSS and some responsive options. Now lets code our css in head section.
<style>
body {
font-family: Arial, sans-serif;
margin: 0;
padding: 0;
background-color: #f0f0f0;
}
.container {
max-width: 600px;
margin: 50px auto;
padding: 20px;
background-color: #fff;
border-radius: 5px;
box-shadow: 0 2px 5px rgba(0, 0, 0, 0.1);
}
h1 {
text-align: center;
}
label,
input,
button {
display: block;
width: 100%;
}
input {
margin-bottom: 10px;
padding: 10px;
border: 1px solid #ccc;
border-radius: 3px;
}
button {
margin-top: 20px;
padding: 10px;
background-color: #4CAF50;
color: #fff;
border: none;
border-radius: 3px;
cursor: pointer;
}
textarea {
width: 100%;
margin-top: 20px;
padding: 10px;
border: 1px solid #ccc;
border-radius: 3px;
}
.btn-container {
display: flex;
justify-content: flex-end;
align-items: center;
margin-top: 20px;
}
.copy-btn,
.share-btn {
display: flex;
align-items: center;
background-color: #2196F3;
color: #fff;
border: none;
border-radius: 3px;
cursor: pointer;
padding: 8px 15px;
transition: background-color 0.3s;
}
.share-btn {
margin-left: 10px;
background-color: #4CAF50;
}
.btn-container button:hover {
background-color: #0e7ce8;
}
.copy-icon,
.share-icon {
margin-right: 5px;
}
</style>2. In body section we will write somebody external code that are included box, button and other important things. This section will contain the main body of a website.
<body>
<div class="container">
<h1>Robots.txt Generator</h1>
<label for="user-agent">User-agent:</label>
<input type="text" id="user-agent" placeholder="e.g., *">
<div id="allow-container">
<label for="allow">Allow:</label>
<input type="text" class="allow-input" placeholder="e.g., /">
</div>
<button onclick="addAllow()">Add Another Allow</button>
<div id="disallow-container">
<label for="disallow">Disallow:</label>
<input type="text" class="disallow-input" placeholder="e.g., /private">
</div>
<button onclick="addDisallow()">Add Another Disallow</button>
<label for="sitemap">Sitemap:</label>
<input type="text" id="sitemap" placeholder="e.g., https://www.example.com/sitemap.xml">
<label for="crawl-delay">Crawl-delay (in seconds):</label>
<input type="number" id="crawl-delay" placeholder="e.g., 5">
<button onclick="generateRobotsTxt()">Generate robots.txt</button>
<textarea id="robots-txt" rows="10" readonly></textarea>
<div class="btn-container">
<button class="copy-btn" onclick="copyToClipboard()">
<span class="copy-icon">📋</span> Copy to Clipboard
</button>
<button class="share-btn" onclick="shareViaEmail()">
<span class="share-icon">📧</span> Share via Email
</button>
<button class="share-btn" onclick="shareOnTwitter()">
<span class="share-icon">🐦</span> Share on Twitter
</button>
</div>
</div>
<body>3. In the final section we will add some JavaScript code to function our body text or element. In this JavaScript code we are using Robots.txt generator function to generate complete Robots.txt files and text.
<script>
function addAllow() {
const allowContainer = document.getElementById('allow-container');
const input = document.createElement('input');
input.type = 'text';
input.className = 'allow-input';
input.placeholder = 'e.g., /';
allowContainer.appendChild(input);
}
function addDisallow() {
const disallowContainer = document.getElementById('disallow-container');
const input = document.createElement('input');
input.type = 'text';
input.className = 'disallow-input';
input.placeholder = 'e.g., /private';
disallowContainer.appendChild(input);
}
function generateRobotsTxt() {
const userAgent = document.getElementById('user-agent').value;
const allowInputs = document.querySelectorAll('.allow-input');
const allowDirectives = Array.from(allowInputs).map(input => input.value).join('\nAllow: ');
const disallowInputs = document.querySelectorAll('.disallow-input');
const disallowDirectives = Array.from(disallowInputs).map(input => input.value).join('\nDisallow: ');
const sitemap = document.getElementById('sitemap').value;
const crawlDelay = document.getElementById('crawl-delay').value;
const crawlDelayDirective = crawlDelay ? `Crawl-delay: ${crawlDelay}\n` : '';
const robotsTxtContent = `User-agent: ${userAgent}
Allow: ${allowDirectives}
Disallow: ${disallowDirectives}
${crawlDelayDirective}Sitemap: ${sitemap}`;
document.getElementById('robots-txt').value = robotsTxtContent;
}
function copyToClipboard() {
const robotsTxtContent = document.getElementById('robots-txt');
robotsTxtContent.select();
document.execCommand('copy');
alert('Copied to clipboard!');
}
function shareViaEmail() {
const robotsTxtContent = document.getElementById('robots-txt').value;
const subject = encodeURIComponent('Robots.txt Content');
const body = encodeURIComponent(robotsTxtContent);
window.location.href = `mailto:?subject=${subject}&body=${body}`;
}
function shareOnTwitter() {
const robotsTxtContent = document.getElementById('robots-txt').value;
const tweet = encodeURIComponent(robotsTxtContent);
window.open(`https://twitter.com/intent/tweet?text=${tweet}`);
}
