How to Build Loyal Readers on Your Blog

If you have loyal readers on your blog, who come to your blog every time you publish new content or come to your blog on a regular basis, you will have continuous traffic even when your SEO efforts are not paying.
Newsletter subscription: If you can get your visitors to subscribe to your blog, and if people voluntarily subscribe to your blog, you can build a loyal reader base.
Social media following: If you manage to build followers organically, you will also have loyal readers on your blog.

I am not sure if this will work but I think it is good to give a shout out to the people who visit your blogs almost every time so that they will remain loyal to you

I think that the writers can always achieve that through the provision of the most liked content by their readers.
