Hi, I have some questions regarding backlinks. I have a website which is 5 months old and has alexa rankings. I am trying to build backlinks for it. I got a list of Do-follow blogs. I commented on them with my domain name at the website column in the comment section. Most of them approved my comments. But when I check sites like rank signals and backlink checker to see my back link count, they say I don't have any back links. Am I doing anything wrong?
