There are a lot of blogger tips and advice out there. yet, I'm writing my own, I am not a very experienced blogger, but I've learned somethings along the way.
I've red some blog posts where the blogger complaints about their blogs' numbers not growing : no new followers, small amount of daily views, not that much comments. And this bother a lot of bloggers. Sometimes they even end up giving of on their blog because they are not happy with their numbers. There are a few things that I do that helps me keep growing, steady and slowly, that do not take much extra time.
1- Visit other blogs and leave comments that are meaningful. Don't just copy-past a random comment like "Lovely Post" or "Very Interesting". Say something that is actually related to the post and you can also leave a question, so the other blogger comes to your blog and also leaves you a comment with the answer.
2 - Reply and return comments. Try to keep in touch with other bloggers. If someone takes the time to come to your blog and leave a nice comment, it is polite -- to say the least -- to go to their blog and also leave a nice comment.
3 - Leave your url in every comment. Every comment you leave, creates viability for your blog. so you should leave your url or a link to you blog in every single one.
4 - Try to find two or three new blogs a day, follow them and leave a comment about their last post and end it saying something like :"Hey, you have such a nice blog, I'm following you. I would love if you could follow me too".
And how to find new blogs? You can try to find them on platforms like Bloglovin' or you can just google a product + review + blogspot and you'll most probably find very diffident blogs. Just make sure the blog is still active (if the latest post has maybe like a week or two).
5 - Don't unfollow blogs. I don't think that there are a limit of blogs that you can follow so there is no need to unfollow blogs, even if that blogger doesn't follow you. Don't forget that leaving a comment increases your blog's visibility.
I try to follow this tips. I try to use the time that I spend on the bus, in the morning and in the afternoon, to visit blogs, and to leave comments. This method is giving me 1 to 3 new followers each day -- which I think is really good!
Let me know if you already follow this tips and what do you do to keep your blog growing :)
