To automate checking whether the links on a website are working, you can use several tools and methods, depending on your preference for programming or using external services.
Python
Python is a great option if you want more control and automation. You can write a script that crawls your website and checks the status of each link using libraries like requests and BeautifulSoup.

from bs4 import BeautifulSoup
# Function to check if the URL is working
def check_url(url):
try:
response = requests.get(url)
if response.status_code == 200:
return f"{url} is working!"
else:
return f"{url} returned {response.status_code}."
except requests.exceptions.RequestException as e:
return f"{url} failed to load. Error: {str(e)}"
# Function to scrape all links from a given page
def get_links_from_page(page_url):
try:
response = requests.get(page_url)
soup = BeautifulSoup(response.content, "html.parser")
links = []
for link in soup.find_all('a', href=True):
links.append(link['href'])
return links
except Exception as e:
return f"Error scraping links from {page_url}: {str(e)}"
# URL of the website to check
website_url = "https://yourwebsite.com"
links = get_links_from_page(website_url)
for link in links:
print(check_url(link))

Ruby
You can automate checking links on a website using Ruby by leveraging libraries like nokogiri to parse HTML and net/http to check link statuses.
Here’s a simple Ruby script to check the links of a website:
Step-by-step guide:
1. Install necessary libraries:
Run the following command to install the required libraries if you don’t have them installed:
2. Create the Ruby script:

# Check each link
links.each do |link|
# Handle relative URLs by converting them to absolute

full_link = URI.join(website_url, link).to_s

How the script works:
1. get_links function:
• This function takes a page URL and uses nokogiri to extract all the <a> tag links from the webpage.
• It returns an array of links.
2. check_link function:
• This function takes a link, makes an HTTP request using net/http, and checks the status code.
• It will print whether the link is working or if it returned an error code (like 404, 500, etc.).
3. Handling Relative URLs:
• The script ensures that relative URLs (like /about-us) are converted into absolute URLs.
Running the script:
1. Save the script in a file, e.g., check_links.rb.
2. Run the script with:
This script can be scheduled to run periodically using cron jobs for continuous monitoring. You can also modify it to save the results to a log file or send a notification when broken links are detected.
