JDoughs is correct.
The number of posts per day also creates an 'expectation' of how many posts you will make in the future. A site updating 5x per day consistently will do better than a 1x per day... But 1x per day consistently will do better than 20x per day once in a while and 0x per day for weeks.
Buy or create a year of content. Then automate publication with a set schedule to make it live. Once you have a year of content your site will update consistently with no guesswork.
