Definition: What is Log File Analysis?
Log file analysis in SEO refers to the process of examining server logs to understand how search engine bots interact with a website. This analysis involves downloading and auditing the site’s log file to identify bugs, crawling issues, and other technical SEO problems. Log files contain information about every request made to the server, including details on how people and search engines interact with the site.
How It Works
Function and Concept
Log file analysis involves analyzing the records from web servers to measure the crawl behavior of search engines. This includes understanding the HTTP requests, response codes, and other interactions between the server and search engine bots. The process typically involves uploading log files to a log file analyzer tool, which processes and analyzes the data to provide insights into search bot activities.
Practical Use Cases

Analyze which URLs are being crawled by search bots, when, and how frequently.
Discover Crawl Frequency
Understand how often search bots crawl the site, which pages are prioritized, and any obstacles encountered.
Audit Redirects
Identify temporary and permanent redirects that might affect search engine crawling.
Improve Crawl Budget
Optimize the site to ensure search engines are not wasting resources on irrelevant or broken pages.
Identify Large & Slow Pages
Review the average bytes downloaded and time taken to load pages to identify performance issues.
Find Uncrawled & Orphan Pages
