What is internal linking?
Internal links connect the content of a website and give Google an idea of the structure of your website. Internal linking apart from reducing the bounce rate also boost your page’s concreteness by providing valuable information.
You can simply practice internal linking by adding links inside your blog posts directing to other blogposts or pages inside your website
Do I have to use UTM in internal links?
No, you don’t need to use UTMs. It will confuse analytics and it will create a lot of “noise”
