A user agent is a computer program representing a person, for example, a browser in a Web context.
Besides a browser, a user agent could be a bot scraping webpages, a download manager, or another app accessing the Web. Along with each request they make to the server, browsers include a self-identifying User-Agent HTTP header called a user agent (UA) string. This string often identifies the browser, its version number, and its host operating system.
Spam bots, download managers, and some browsers often send a fake UA string to announce themselves as a different client. This is known as user agent spoofing.
A typical user agent string looks like this: "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:35.0) Gecko/20100101 Firefox/35.0".

This data enables companies and website owners alike to better understand the uptime and response time of their site(s). As an uptime monitoring company, we make every effort to minimize Timebox's impact on servers.
Shown below is a sample log file entry for the UptimeRobot web robot. It’s derived from an Apache web server log file.
From the log entry information about how the robot identifies itself, HTTP Sergeant, and where it is hosted are given. However, if you wish to prevent the robot from visiting a website you may wish to try including the following entry in the robots.txt.
You may also wish to trial controlling the frequency of UptimeRobot visiting your site, setting a minimum acceptable delay between consecutive requests can be set with the following added to the robots.txt file: UptimeRobot provides a monitoring service for websites, servers and domains.
Periodically the UptimeRobot will visit a website to determine whether the viewed page matches a given criteria. Every 5 minutes (or more depending on the monitor’s settings), If the status code doesn’t indicate a problem, we are good If the status code is~400+ and 500+, then the site is not loading In order to make sure the site is down, Uptime Robot makes several more checks in the next 30 seconds, If the site is still down, it sends an alert.

The referenced website confirms that the bot supports the robots' exclusion text and also obeys the crawl delay. Details are given about both preventing the robot from indexing the website and how to adjust its crawl rate.
Their advice is to include the following entry in the robots.txt file to prevent Timebox from visiting your site If you would like to limit the crawl rate you may wish to try the following which sets a minimum acceptable delay between consecutive requests of 10 seconds.
Periodically the Timebox will visit a website to determine whether the viewed page matches a given criteria. Unmaintained Ansible versions can contain unfixed security vulnerabilities (CVE).
This module will let you start and pause Uptime Robot Monitoring Protection I upgraded my BPS Pro plugin to version 5.7 today.

But it is a good idea to allow the search engine bots or crawlers manually to your site. One of the best ways to allow or disallow a search engine to crawl your website is to create a ‘robots.txt’ file.
And, by the time you are done reading this article, you will be able to allow or even disallow search engine bots like the ‘Google bot, Bingo, and Yahoo! As well as, we will add screenshots to each step to make it easier.
Foreground Server Speed How to allow search engine bots? In a nutshell, you will need a text file on the root directory of your website.
When a search engine visits your site to index the updated pages or posts from your website. First, it will directly go to check the ‘robots.txt’ file on your website.
From there, you will be able to instruct it to crawl your site or not using some specific line of codes which will be inside the ‘robots.txt’ file. Then the search engine bot will follow the instructions.
However, if you don’t have any ‘robots.txt’ files on your website then the search engine will index things randomly. On the address bar of your browser, Type on the URL of your site but add the extension ‘robots.txt’ at the end of the URL.

Rename After that, open the ‘robots.txt’ file and you need to type some specific lines of codes which you will find on the next section Seven, if you don’t know what to type in inside the ‘robots.txt’ file.
Then you can follow along to learn all the variations of codes which can be used in a ‘robots.txt’ file. Note: Do not directly copy and paste the codes from below.

Fortunately, if your site already has a ‘robots.txt’ file and want to edit it then you can use the same method which will be described below to do that. To edit the file you need to be on the ‘public_HTML’ folder of your web server.
For instance, we have added the sitemap URL to the code Or, you might have just added new lines of codes to your newly created ‘robots.txt’ file.
So, always use lowercase and the name should be ‘robots.txt’ A blank line on the code will tell the search engines that a new instruction needs to be followed. You can add the URL of the sitemap of your website on the ‘robots.txt’ file.
Plus, add a blank line between the ‘Sitemap:’ and the previous codes. And if your site has already been indexed by the search engines, then it will not erase that.
In case of that if you need to erase any URL form the search engines then you have to contact the search engine to erase the indexed URLs The ‘robots.txt’ file should be uploaded to the root directory of your website which means the ‘public_HTML’ folder of your web host account. If you have followed the guide above then it will not be a problem to add a ‘robots.txt’ file to your website.
