Lære Automating Internal Link Analysis | Automating SEO Tasks with Python

Internal linking is a crucial aspect of SEO because it helps search engines crawl a website efficiently and distributes link equity throughout the site. By strategically linking pages together, you can guide both users and search engines to important content, improve crawlability, and enhance the overall structure of your website. Python is a powerful tool for automating the analysis of internal links. Using Python, you can quickly map out how your pages connect, identify potential issues such as orphan pages (pages with no internal links), and optimize your site’s internal link structure for better SEO performance.

# Simulate a website as a dictionary where keys are page URLs and values are lists of internal links

website = {
    "/": ["/about", "/products", "/contact"],
    "/about": ["/", "/team"],
    "/products": ["/", "/products/widget", "/products/gadget"],
    "/products/widget": ["/products", "/contact"],
    "/products/gadget": ["/products"],
    "/contact": ["/"],
    "/team": ["/about", "/contact"],
}

# Print out the internal link structure
for page, links in website.items():
    print(f"Page: {page}")
    print("  Links to:")
    for link in links:
        print(f"    {link}")

To analyze internal links with Python, you need a way to represent the relationships between pages. A common approach is to use a dictionary, where each key is a page URL and its value is a list of other URLs it links to internally. This structure effectively models the website as a graph, with pages as nodes and links as edges. Traversing this structure is straightforward: you can loop over each key-value pair to see which pages are linked from each one. This makes it easy to perform tasks like counting links, finding unlinked pages, and visualizing the link network.

# Function to count the number of internal links for each page

def count_internal_links(site_structure):
    link_counts = {}
    for page, links in site_structure.items():
        link_counts[page] = len(links)
    return link_counts

# Example usage
counts = count_internal_links(website)
for page, num_links in counts.items():
    print(f"{page}: {num_links} internal links")
