The meaning of ‘canonical’ and ‘canonicalisation’
Canonicalisation, and related terms ‘canonical links’ and ‘canonicalised’, is an important concept in online marketing. It refers to selecting the best URL for a webpage when there are multiple versions. In simple terms, it means choosing the preferred version of a webpage to be indexed by search engines. This avoids issues with duplicate content and ensures a website’s SEO efforts aren’t weakened. To miss-quote Lord of The Rings, ‘One page to rule them all’.
Canonicalisation and canonical links in marketing
Canonicalisation is vital in online marketing. As search engines get smarter, website owners must make sure their content is optimised and easy for search engine crawlers to understand. If not done correctly, it can lead to lower rankings, reduced visibility, and missed opportunities to drive traffic and generate leads.
A common situation where canonicalisation is needed is when a website has different versions of the same content. This can happen due to tracking parameters, session IDs, or different protocols like HTTP and HTTPS. Search engines may see these as separate pages, causing duplicate content problems, which can hurt the website’s SEO.
Using canonical tags helps website owners tell search engines which version of the content is the main one. This keeps the link equity focused on one URL, preventing the SEO impact from being spread too thin. It also helps avoid penalties for duplicate content, which can lower rankings and reduce visibility.
Another key part of canonicalisation is using 301 redirects to point duplicate URLs to the main one. This tells search engines to ignore the duplicates and focus on the correct version. It also improves the user experience by ensuring visitors are always directed to the right page.
In summary, canonicalisation is a crucial part of online marketing that ensures a website’s content is optimised for search engines. By choosing a preferred version of a webpage and using canonical tags and 301 redirects, website owners can avoid duplicate content issues, consolidate link equity, and improve their SEO. Ultimately, this leads to more traffic, better visibility, and more leads—making it a must for anyone looking to succeed in the competitive world of digital marketing.
