Missing Canonical Tag

Without canonical tags, Google can index duplicate URLs and split your ranking signal. Here's how to add them right.

What it means

Pages don't include a <link rel="canonical"> tag pointing to the preferred URL.

Why it matters

Without canonicals, the same content reachable at /page, /page?utm=..., /page/ (trailing slash), and https vs http can all be indexed separately, splitting link equity.

How to fix it

Add <link rel="canonical" href="https://yoursite.com/page"> to every page.
Use the absolute URL with your preferred protocol and domain.
Self-canonical (page points to itself) is correct for unique pages.
For deliberate duplicates (print version, AMP), point at the master.

Example

Before

<!-- No canonical -->

After

<link rel="canonical" href="https://freeseo.in/pricing" />
