As a website owner, it’s important to take steps to stop bot traffic from crawling your website.
Bots, also known as crawlers, spiders or web robots, are programs that automatically explore the internet and index website content for search engines. However, not all bots are good, and some may harm your website’s performance and security.
Learn how to stop bots from crawling your website, including good and bad bots like Googlebot and spam bots, which can negatively impact your site’s SEO and performance. Using techniques such as robots.txt, IP blocking, and CAPTCHA, you can prevent bot traffic and create rules for search engines to crawl your site.
How To Stop Bot Traffic From Crawling Your Website
There are several steps you can take to prevent bots crawling the website. One way is to use the robots.txt file to disallow certain types of bots from accessing your site. You can also block bots by their user agent, IP address, or even by specific search engines like Google.
Good bots that help with indexing and crawling your site should be allowed, but bad bots and spam bots should be blocked. To prevent bots from crawling your website, you can start by identifying the types of bots that are accessing your site.
User agent strings can help you determine the identity of the bot and its purpose. For example, Google’s crawler is called “Googlebot”. You can also use your website’s analytics to identify bot traffic, such as high bounce rates or suspiciously low time on site.
One of the most common ways to block bots from crawling your site is by using the robots.txt file. This file is a set of instructions that tells search engines and other bots which pages or resources they are allowed to access on your site. You can use this file to disallow access to certain pages or directories that you don’t want to be indexed or crawled.
You can also block bot traffic by IP address or user agent using the .htaccess file on your web server and adding certain rules to the file. This file contains configuration settings that control access to your website.
Another way to prevent bots from crawling your site is to use a firewall that blocks known bad bot traffic. Many web application firewalls (WAFs) have built-in features to block bot traffic, including malicious bots, based on user agents or IP addresses. By implementing a WAF, you can also protect your website from other types of cyber threats, such as DDoS attacks, SQL injections, and cross-site scripting (XSS) attacks.
It’s also important to regularly monitor your website traffic and analyze your server logs to identify any suspicious bot behavior. By monitoring your website traffic, you can detect any unusual spikes in traffic that may indicate bot activity. You can also use tools such as Google Analytics to analyze your website traffic and identify any high-bounce pages that may be attracting bot traffic.
It’s Important To Note That Not All Bots Are Bad Bots
Some good bots, such as those used by search engines, can help improve your website’s SEO and visibility. Therefore, it’s important to use tools to differentiate between good and bad bots, and only block the ones that are harmful.
Blocking malicious bots from crawling your website can improve your website’s performance, security, and SEO. By taking control of the access to your website and monitoring bot traffic, you can create a better experience for your users and protect your website from spam bots, duplicate content, and other issues.
To Stop Bots From Crawling Your website, You Can Use A Combination Of The Following Techniques:
1. Identify Bot Traffic
Use tools such as Google Analytics to identify bot traffic on your website.
2. User-Agent:
Check the user-agent string of the bots that crawl your site. This will help you identify the types of bots that are crawling your website.
3. Robots.txt file:
Use a robots.txt file to tell search engines which pages of your site to crawl and which pages to ignore.
4. Disallow Duplicate Content:
Use canonical tags to disallow duplicate content.
5. Block Bad Bots
Block bad bots using the IP address or user-agent string. You can also block bots using the .htaccess file.
6. Allow Good Bots:
Allow good bots such as Googlebot to crawl your site by not blocking them in the robots.txt file.
7. Use A Web Server:
Use a web server to manage your website’s performance and security.
8. Use Tools:
Use tools such as Google Search Console to manage your website’s crawl rate and to monitor for security issues.
9. Monitor Bounce Rate:
Monitor your website’s bounce rate and identify any high bounce rate pages. This may indicate that bots are crawling your site too much.
10. Use A Solution:
Consider using a third-party solution to help manage bot traffic and block malicious bots.
Other Tips And Tricks To Stop Bots
Although using the robots.txt file is your best bet to stop bots, here are some other tips and tricks you should know about. Before that if you want to know how to write a code, for say, Ahrefs or semrush, follow this example –
User-agent: AhrefsBot
Disallow: /
Or,
User-agent: SemrushBot
Disallow: /
1. Blocking Outdated Browsers
You must block outdated browsers or agents because the default configuration of many of these scripts and tools have user-agent string lists that are no longer of use. You can also CAPTCHA the following web browsers –
- Firefox version less than 38
- Chrome version less than 41
- Safari version less than 9
- Internet explorer less than 10
2. Blocking Hosting Providers
Even though advanced attackers are likely to use hard-to-block networks, you must block hosting or proxy networks that are easily accessible. Blocking such networks is enough to stop many attackers from targeting your API, site, or mobile apps.
3. Failed Login Attempts
It’s important to define how many failed login attempts are fine before you become suspicious of malicious activity. This will help you determine the spike or anomalies and set alerts to get timely notifications. We recommend setting global thresholds because advanced “low and slow” attacks fail to trigger user-level or session alerts.
4. Public Data Breach
Keep an eye out for public data breaches since credentials that have recently been stolen are more likely to be active. If a large breach has occurred recently, there is a high chance bad bots will run those credentials against your site with greater frequency.
5. Bot Mitigation Solution
The major problem with trying to stop bots from crawling a website is that modern bots mimic human behavior, which helps them bypass traditional security tools. That’s why you must evaluate bot mitigation vendors since they offer full support and possess the necessary industry experience for control over abusive traffic, while guaranteeing greater visibility.
6. Protecting Bad Bot Access Points
There are several bad bot access points, such as exposed mobile apps and APIs, apart from your website. Hence, you must share blocking information between systems to close all backdoor entry points.
FAQs
Q1. What are bots?
Bots, short for robots, are software programs that perform automated tasks, such as web crawling or chatbot interactions.
Q2. What Is Bot Traffic?
Bot traffic refers to the visits to a website made by automated software programs known as bots. Some bots are good, such as those used by search engines to crawl and index web pages, while others are bad, such as those used by hackers to scrape data or perform other malicious activities.
Q3. What Is A User Agent?
A user agent is a string of text that identifies the software used to access a web page. Browsers and search engine bots both have user agents that identify such software.
Q4. What Is A Robots.Txt File?
A robots.txt file is a text file that tells search engine bots which pages or sections of a website they are allowed to access.
Q5. What Is A User Agent Googlebot?
Googlebot is the user agent used by the Google search engine to crawl and index web pages.
Q6. What is An .Htaccess File?
An .htaccess file is a configuration file used on web servers that allows website administrators to control access to specific directories or files.
Conclusion
There are various ways to stop bot traffic from crawling your website, including the use of robots.txt file, user agent and IP address blocking, or the creation of rules in the .htaccess file. But it is important to differentiate between good bots like search engine crawlers and bad bots like spam bots or malicious crawlers to disallow the latter from accessing your site.
Blocking bot traffic can improve website performance, reduce high bounce rates, and enhance online security. By using the appropriate tools and resources, businesses can take control of bot management to create a solution that works for their specific needs.
