I read a lot of posts of people who managed easy to rank websites with 10 - 20 posts , with a main keyword with about 1000 searches per month. Other people said that now is much harder to rank a micro niche website, than it used to be. I'm trying with a website with 20 posts, and I can't rank for the main keyword over position 50 in Google, and for the long tail keywords I can't get better than position 8 - 15. The first page is occupied by websites with Domain authority over 30 - 40, while mine had 9. The pages of competitotors don't have more backlinks than my pages, and some of them even don't had backlinks. But it looks like my micro niche website need a lot of backlinks to compete with them. Should I try with other niche, or I should add more posts, because my website is too small and micro niche sites are useless?
