What the Common Mistakes to Avoid with Canonical Tags?

Here are some of the most common mistakes to avoid with canonical tags:

• Using the wrong href attribute value. The href attribute value should point to the original version of the page. If you point it to a different page, it will create a redirect loop, which can hurt your site's SEO.
• Not using canonical tags on all duplicate pages. If you have multiple pages that are essentially the same content, you should use a canonical tag on all of them. If you don't, search engines may not be able to determine which version of the page is the original.
• Using canonical tags on pages that are not duplicates. Canonical tags should only be used on pages that are essentially the same content. If you use a canonical tag on a page that is not a duplicate, it will not have any effect.
• Using multiple canonical tags on a single page. You should only use one canonical tag on a single page. If you use multiple canonical tags, search engines will not know which one to use.
• Putting the canonical tag in the wrong place. The canonical tag should be placed in the head section of the HTML code. If you put it in the body section, it will not be effective.
