What is a Canonical URL? Canonical URL Review

Canonical URL ( authoritative link ) is generated by the Amazon system and is used for off-site promotion and traffic diversion. While diverting traffic, you also increase the weight of your link, improve your link ranking on search engines, and increase search engine traffic entrances.

Get authoritative links

Step 1: Use Google Chrome to open the Amazon website and find the listing of the target ASIN. You can search or directly enter the ASIN.

Step 2: Press F12, then CTRL+F and search: canonical to get the authoritative link.

Use authoritative links

Publish the authoritative link directly as a naked link (also known as ASIN link) to external sites (for example: personal blogs, official websites, Facebook, Twitter and other external resources), or you can send keyword links to external sites.

Advantages

Using authoritative links for promotion is the safest and most effective. Because in a sense, any link you send outside the site is absorbing weight for this page, so when using the promotion mode on off-site tools, using authoritative links can maximize the efficiency of the links.
