There is no definitive answer to this question as it largely depends on the individual blog and the type of content on that blog. However, some people believe that engaging in blog commenting can help improve a blog’s SEO.
This is because search engines favor websites that are well-liked and have a large audience. Comments left on a blog by readers can help to boost the visibility of that blog and make it more likely that Google will index it.
However, it is important to remember that there is no guarantee that linking to a blog through comments will improve its SEO. Furthermore, it is also important to keep in mind that not all comments left on a blog are going to be indexed by Google.
So, while commenting on a blog may help to boost its visibility and audience, it’s still important to produce high-quality content if you want your blog to rank well in search engine results pages.
