What are Canonical Tags?
A canonical tag (or rel=canonical) tells search engines which version is the “main” version of a page from the other, identical or very similar pages.
Canonical tags can be used to specify which version of the content should be indexed if multiple URLs are available with the same or similar content.
<link rel="canonical" href="https://www.bapugraphics.com/blog " />
What are the benefits of canonical tags for SEO?
They help manage syndicated content
Search engines use Canonical Tags to determine which websites contain the original content and which ones republish it
There are many website owners who (either for promotional purposes or for another purpose) post their content on other websites.
It is up to Google to choose which website is the initial resource of this content and also ought to be presented as a search results page as well as which internet site simply promotes it.
This problem can be resolved by implementing canonical tags on external websites in order to promote the original, main version of the page in Google search results.
In this way, crawling is improved
Using canonical tags makes it easier for search engines to crawl and index pages that you actually want to be crawled and indexed instead of duplicates that shouldn’t be crawled.

Canonical tag best practices
1. Use absolute URLs
In contrast to relative URLs, absolute URLs in canonical tags can help you avoid unintentional mistakes or incorrect interpretations by search engines. If possible, absolute URLs should also include https, //, www, and trailing slashes.
Example of Absolute URL in canonical tag.
<link rel="canonical" href="https://www.bapugraphics.com/pagename/" />
Example of real UEL in canonical tag.
<link rel="canonical" href="/pagename/" />
2. Use lowercase URLs
In URLs, search engines like Google can be sensitive to uppercase and lowercase letters. By using lowercase in canonical URLs, you can avoid duplication issues with search engines. Whenever possible, use lowercase URLs on your servers as well as canonical tags.
3. Make use of self-referencing canonical
it is always a good practice to include a canonical tag on a page that indicates itself– even if you did not make use of canonical tags on the rest of the duplicate pages.
