Optimal Number of Blog Posts per month to Rank in a 'Moderate' Niche.

Hello!

I am fairly new to SEO, and my first project is my own company's website. I've learnt a bit about keyword research, On-Page SEO, and Backlinks through multiple guides, articles, and Udemy courses. I am not that proficient yet, hence would be grateful if you guys help.

Main Question Here!

My business operates in a niche where most of the keywords I have researched have a KD of below 45. Now, I'm cranking out blog posts on a regular basis (nothing spam, everything is well-researched and properly curated).

My last few RankMath and SEMRush's Content Analyzer scores were (95, 9.6), (88, 9.2), (92, 9.1) respectively.

Accordingly, how many blog posts should I publish per month to make my blog/site rank in the Top 2-3 SERPs?

Please let me know if the information I have provided is insufficient to answer such a question.

Thank you!
