Keep your posts simple! Do not try to impress anyone. be yourself! Visit other blogs which might interest you, take part in conversations or simply put your two cents for others to read and follow you back to your blog.
Put advertisement but make sure that your blog visitor doesn't get irritated when ads pop up one after another like a flood.
After completing your post, read it with a fresh eye from the perspective of a reader to check if you enjoy it or if it needs changes.
It was lovely knowing your takeaways from 2017. Now, let us hear your wishes for 2018. Aren't we all looking at the new year with love and hope? It is better to write down and then refer to it regularly if you really care about them.
