What is a canonical issue?

Search engines face confusion when a website contains many pages that share identical content causing negative effects on SEO outcomes. A canonical issue emerges when search engines face confusion because of duplicate content that stems from different URL paths.\
\
For example, a webpage might be accessible via two URLs like:

1. `www.example.com/page`
2. `www.example.com/page?ref=123`

Both URLs show the same content, but search engines treat them as separate pages, which can dilute the ranking potential of that content. This is known as **duplicate content**, and it can lead to SEO problems like:

- Lower search engine rankings
- Reduced crawl efficiency
- Split link equity (backlinks pointing to different URLs instead of one)

To resolve this, a **canonical tag** is used. A canonical tag is an HTML element that tells search engines which version of a page is the "preferred" or "original" one. It consolidates link equity and prevents duplicate content issues.\
