SEO Audit: Not an Exact Science
There’s a reason why there’s no one-size-fits-all approach to a successful SEO audit. It’s also why SEO “best guidelines” are sometimes inconsistent. Google is an enigmatic beast. It alters its algorithm on a regular basis and rarely explains why or how it did so.
🧾 Glossary

Search engines have their own site crawlers; for example, Google has its “Google bots.”
These bots, commonly known as “crawlers” or “spiders,” go over new or updated websites, examine the content and metadata, and index the content collected.

These site crawlers may examine the health of your website as well as your rivals’ backlink profiles.

An XML sitemap is a file that lists a website’s important pages, making sure Google can find and crawl them all. It also helps search engines understand your website structure.

Robots.txt is a file connected with your website that tells web spiders whether or not to crawl certain parts of your website.
What Is a Log File?
A log file is a text file that records all of a server’s queries, both from people and crawlers, as well as its answers to those requests.
