Today I learned about canonical URLs. While looking into how I can syndicate content from this site, specifically longer form blog posts on other sites like dev.to, I came across canonical tags.
Basically they're a way of telling the internet, specifically search engines, what version of your content is the main copy or single-source of truth.
Currently I've configured my site so it's not indexed or crawled. However, for sites I don't own I don't have the same level of control. Check out the canonicalization and SEO best practices for canonical URLs articles from Moz if you're interested in learning more.
